As a wholesaler,do you know how to check your faucets quality?

Perhaps,many wholesalers don't check their products quality by themself,just ask their suppliers to do these,if problem comes,you may need to return to your supplier,and change new some,that will lost your time,why not check the products before you received it?Like faucets,there are many things you should know about.

(of course,you can't check it just at home,because it need some special test equipments).

Maybe the next checking list is boring,but that is what we have to do before shipment,to ensure each of our products is in good quality.

(PS. Also you can set the QC standard to your supplier,that may be easier for you. :) )

Hot and cold faucet working principle

Faucet is a great invention,so that we can experience fun of life and convenient,but what is the internal structure of hot and cold faucet?Do you know which parts will be used when it is working?

hot and cold faucet mainly make up by handles, valve core,inlet and out let braid tube,and other installation accessories. Ceramic valve working principle:generally,there are 3 holes under the bottom of the ceramic valve,one for cold water,one for hot water,the other for internal water outlet.The valve holes which for cold and hot water both have sealing ring,to guarantee in sealed condition when the faucet body is in incline,ensure that the cold tube and hot tube after cold and hot water pipe body connection to ensure hot water pipe and cold water pipe is one-to-one correspondence with the valve cold and hot hole.So the valve is mainly to control open-close of these two hole to realize hot and cold water come out.

Handle drives the valve rod moving,make ceramic chip moving to make the two holes sealed,so no water into the valve.The valve sealing ring to make that water have to pass the valve and then can come out from the faucet,no water into valve,no water flow out.This is working principle of faucet.

When we turn on the faucet on the hot water side, hot water hole will open and cold water hole will closed,so the hot water will flow out,this is the hot water in and out working principle.the same as the cold water working principle.if the two is open the same time,warm water will flow out.

The classic bathroom products in 20 century

Compared with entertainment, catering, FMCG industry,sanitary industry is so low profile.But Banyan believe that everyone is no stranger to bath product, mention faucet,everyone will think of hot and cold faucet,referred to toilet, everyone will think of buttons flush function,mention intelligence,everyone will think of intelligent toilet cover.

Next, will list some classic bath products in the last century,for their presence,more and innovative sanitary ware products had became,to make people's lives more convenient.

HCG Alps series in 1980

Toilet is quite rare in the 1980s,is limited by the complicated manufacturing process,there is less than five manufacturers can produce independent toilet. And then,HCG had made the Alps first product - low cistern mute independent toilet after 18 months,thousands of adjustment test.And first Alps ahd created sales of 100000 sets, and created the hot-selling for more than 20 years, Accumulative total sales up to 38 million.

TOTO WASHLET in 1980

In the early 1960s,Bedet industry put forward a question that,body should be cleaned if dirty,should be cleaned hands after toilet,so,if wash buns is more clean and comfortable?In 1964,TOTO began to research and development the product which can water washing after toilet in convenient,through hundreds of thousands of testing and improving,WASHLET came out in 1980.It subvert the traditional way of using toilet,water washing instead of paper,to bring clean and comfortable bathroom experience for consumers all over the world.

TOTO,always leading technology trend more than 30 years,WASHLET constantly blend in advance humanization intelligence technology. Global sales breakthrough 40 million in 2015 years. For the first time pushout since 1980, Break through 40 million sales volume after 35 years.TOTO did not release details, but more than 90% WASHLET was considered had been sale in Japan. WASHLET’s popularizing rate has been close to 80% in ordinary families, has been close to 80% in Japan,for manufacturers,expand overseas sales will be the future development.

WASHLET total shipments from 30 million to 40 million,spent four and a half years.At the beginning of the 1980,most consumers did not the habit of "wash buns".But you can compare, from the initial to 10 million shipments,it took 18 years.

Moen: in 1939,the first hot and cold faucet

In Seattle,1937,AI Moen was studying studied mechanical engineering in university,one day,he get burned when he was washing hands under an old double handle bibcock,this make him to find a better way for outlet.Two years later, he finally completed a revolutionary invention which change pipeline industry and daily water supply:single hand hot and cold water mixer faucet,people was mentioned in the same breath with Edison invented the light bulb and Bell invented the telephone,was awarded by internationally famous "FORTUNE" magazine as the 100 the best inventions 20th-century in American.For more than seventy years,Moen's history made the world faucets and plumbing equipment industry change constantly and revolutionary,every footprint as the milestone of modern faucet industry, creating a legend of space and water.

When AI recall this particular night, he said: "it makes me thinking, faucet should let people to control water temperature do as their wishes.When I think this matter further,I more sure that single hand mixer faucet is the solution to this problem, so I began to draw the drawings.”

It was born a immortal patent from these drawings.Since then,AI Moen is recognized as the pioneers to change people’s water using experience.

MOEN brand’s establishment is quite legendary, with strong technological inventions.In the next nearly century,MOEN inheriting and carrying forward to the spirit of unremitting pursuit to technological innovation.In 1950,through Hotpoint’s first precasting single handle kitchen faucet,MOEN was recognized by all over United States;In 1959,MOEN’S single handle kitchen faucet was awarded one of the best design by Fortune.In 1979,MOEN launched double handle faucet,with patent no mat valve.By 1982,AI Moen had invented more than 75 patents.whereafter,Space coating technology,pull out faucet follow control system,fingerprint proof coating,sensor faucet and a series of technologies and products appeared one after another,had won the "most valuable product award", "2008 crystal achievement award", "WaterSense® manufacturer partner of the year award" and so on.

New bath showers for modern life

We take shower almost every day,some people for clean;Some for routine;Some for enjoying pleasure and relaxation... no matter what purpose it is,shower is an indispensable part of life, as time passes,shower culture had been extends out.

In ancient China,there is rule about “the emperor will take a shower before holding court”,it is not only a kind of etiquette,but also a kind of spiritual life.At first people take shower along the river bank or in hot spring,afterwards,have tub,artificial bathing pool,then have shower, as time goes on and changes of bathing way,now,people began to pursue health bathing. In order to convenient, most people will choose shower,of course,in addition to clean and healthy,people also enjoy mental relaxation in bathing.

On the design of shower, in addition to consider cleaning body and relax, but also saving water and other social needs.See the following few shower designs, if more suitable for modern way of life?

1. Double shower

Currently shower equipment generally including top shower and hand shower, but you can not used both at the same time.In fact,if you can use both at the same time will be more healthy and more comfortable.Designer Thomas Baker make a shower which can realize this operation,top shower fixed in the wall and hand shower(can take off) is stucked in top shower.The advantages of this design is that even it is a double shower,but water yield is the same as single way shower.

2. OaSense Intelligent shower head

Although shower is comfortable and efficient,but the biggest drawback is a waste of water, OaSense intelligent shower head is designed for saving water. The appearance of the shower head have not different from other common types, but theres is built-in sensors in it,if people leave under the shower,the shower will stop the flow automatically,according to experiment, the design of suspended water can save 50% water

3. Daphne multipurpose shower

The shower head design by South Korea's designer Park Geun,looks simple and elegant,not only is a shower,but also can as the faucet on basin.There are two part of shower,one for shower head outlet,the other for basin faucet outlet

4. Nana bath system

Female designers from Poland Katarzyna Malczewska had designed a bath system, there is shower and tub inside,looks like a elegant white ribbon. This conceptual design adopted integrated system,not only with practical function and artistic,but also space saving.

5. Spining tub

This is a wall hung bathtub which is Ron Arad designed for bathroom manufacturers Teuco,there is shower system inside,in fact,it is an changeable bathtub,can combines tub with shower and with free transform, the width of bathtub edge is not the same,when the wider edge rotate to the bottom,can be used as a mini tub.But this bathtub have a big problem,you need to a big enough bathroom to install it

6. Watertile shower

This watertile shower is a new product designed by KHOLER,it is installed on the ceiling directly, do not take up space,and not through an external pipe connection. Installed thermostatic valve, don't need to control water temperature, besides,this shower had won the Germany Hanover design awards.

Something you have to know in bathroom decoration

Bathroom is the place where we use most daily, so particularly pay attention to decoration, thoughtful in everywhere.But you will find many what we had not considered in decoration after we finished it, such as socket is not enough,shower height is wrong and so on. Expectation at first,now only regret and helplessness

First,for the waterway

Bathroom is the place use the most water, so must consider about the waterway design before decoration,make a good plan.For fear that it is not enough. Here I compiled a simple list for reference, of course,can be adjusted according to your own actual situation.

Waterway design in Bathroom

1.one washing machine faucet

2.One bibcock for mop pool (although many families will not make a mop pool when decorating,but had better install a faucet is used for washing cloth, etc)

3.The water heater inlet and outlet(this is must be)

4.One toilet connector

5.Hot and cold water mouth for basin

6.two water floor drain

Circuit should not be neglected

Circuit is always the top priority of decoration, with the increasing of home appliance, there is more and more demands for circuit, so as bathroom.Reserve a socket beside or behind the toilet when decorating,mainly considering that it is possible to use smart toilet or can use for hair dryer,of course, the place is not absolutely fixed, can be adjusted according to personal habits.

As for the water heater switch,had better to make as switch panel control, in order to reduce excess loss on unplug; also advocate that the lamp and fan switch install out of the bathroom.Besides waterwat and electricity,there is some other things also need to be pay attention to, and here I also picked out some important for everyone.

Bathroom sink, toilet plumbing need to install the angle valve (angle valve can effectively regulate the water pressure, at the same time can play a role of switch, if the faucet is leaking,you can turn off the angle valve, don't have to shut the master valve), convenient for maintenance after check-in.

To check if had installed the exhaust duct or sealing When installing fan, this step is essential for bathroom decoration, to prevent the smell can not go out in the future.Many families found floor drain is impeded, drainage is not effective after check in.This is because the floor drain hose test was not done after installation, worker will fall cement into the sewer careless,it become solidification after a long time, cause the clogging.So have to do hose testing after installed floor drain immediately.

About floor drain

Floor drain have better to Locate in the middle of the four ceramic tile, not only can make beautiful cutting,also four ceramic tile can be a natural slope like floor drain, avoid hydrops.

When installing water heater, have better to avoid cutting ceramic tile, if not, not only the water heater is hard to be hang , and is very difficult to modify, have to open ground and metope, time-consuming.

Finally, different family have different habits,this is just for reference, can be properly adjusted according to their own situation.

Thermostatic mixer profile

With the pursuit of people's living standard is higher and higher, there is more and more bathtub brands on the market, variety of bathtub is known, but we know how much about bathroom products? All the bathtub cannot leave it, let's come together and learn about it-the temperature mixer.

Thermostatic mixer profile

Thermostatic mixer,also can call thermostatic faucet or thermostatic shower mix faucet,Its role is,mixing the cold water and hot water into a preset temperature of warm water automatically.

Its working principle:equipped with hot temperature sensitive components in the water outlet of thermostatic mixer,control the movement of valve inside, block or open the inlet of cold and hot water.After setting a certain temperature,temperature mixer will adjusting proportion of hot and cold water to keep water temperature constant.

Thermostatic mixer advantage

The main advantages of thermostat mixer:

first,thermostatic mixer can constant temperature on the initial setup automatically, once setting, you do not need set the temperature every time,just turn on the shower and enjoy it, especially convenient for children and elders.

Second, there is water supply disconnection automatic protection function,when temperature is 38 degrees or below 38 degrees,either cold or hot water supply pipes is broken,it will stop working automatically,to prevent burns,cold shock accident effectively

Matters need attention

The usage of thermostatic mixer is very simple.Standard thermostatic mixer have one knob in each side,the left side knobs is for adjusting water temperature,twist forth,water temperature drop,twist back, water temperature increases, but Screw fixed on 40℃.This is because when the water temperature is over 40℃,it is easy to burn the skin, if you need a higher water temperature,must be press on the red safety button,continue to twist back.And right side knobs is for controling output water type and water yield:scale aligned closed; Forward twist,for water nozzle below,twist back,for shower head.the greater the but when installing and using some must be pay attention to matters

Here is some matters need attention when on installation and use

1.If there are tiny solid lumps in your house,is not suitable for using thermostatic mixer.

2.If there is powdery sediment or soft foreign in tap water may reduce the sensitivity of the thermostatic valve,also may Shorten the service life of thermostatic mixer.

3. Try to shorten the distance between water heater and faucet, in order to make hot water reaches to faucet as soon as possible.

4.Normal water pressure:0.05Mpa ~ 0.6 Mpa

5.Water supply pipe must not be wrong, hot water pipe must be on left, cold water pipe must be on right.

6.Must clean up before installing thermostatic faucet, in order to avoid the tiny sand lump damage the rubber gasket, thread, thermostatic valve and other parts.

7.Please according to specification to make the installation, pay attention to do not loss or damage any gaskets.

8.thermostatic mixer doesn’t has heating function, please set water heater's temperature to 65℃~ 80℃.

9.If hot and cold water pressure’s difference is too big, please use a screwdriver to adjust bracket valve. Especially the families using gas water heater.

The most important part for faucet - the valve

Profile of valve

valve element is one of the most important parts for faucets, valves and other fluid control system components. Valve is a component which with direction control,pressure control or flow rate control by its interior turning.Each faucets’s switching control needs a valve,the quality of valve is the important evidence to assess the quality of the entire faucet,or you can think the most important thing to faucet is valve.

steel ball valve and ceramic valve is the common faucet valve.Steel ball valve is good at resist pressure, but the drawback is the seal rubber seals is easy to wear and tear.Compare to steel ball valve,ceramic valve has good better performance in heat-resisting wear-resisting,also ceramic valve have good sealing performance,so its lifetime is very long and with so much opening times,not easy to cause water nozzle leaking for wear and tear of valve.The faucet with ceramic valve,hand feeling is more comfortable, smooth,open and close rapidly.we can not see the valve when we are buying faucet,but we can simply judged the quality of valve based on hand feeling when turning handle. Generally,without block sense,feeling slight,that may be a good valve,but not 100% sure.

There are three kinds of common valve core: stainless steel ball valve, ceramic valve and roll shaft valve. The common characteristic of these 3 valve is:the valve is integral,easy on installation maintenance and replacement.

Roll shaft valve

The advantage of roll shaft valve is: handle rotation smooth, easy to operate,comfortable hand feeling, ageing resistance, resistance to wear. But as old-fashioned valve,it has been gradually can not meet the demand of people for valve,so will gradually eliminated by the market. Roll shaft valve core is very rare in common faucets.

Valve brand

Abroad: Spanish Sedal, Hungary Kerox

Taiwan:KCG valve,Hain-Yo valve

China:Wanhai valve,Mingshi valve

many international valve brands had built factory in China to supply the mainland directly,such as Sedal, KCG

Ceramic valve

Ceramic valve:deformation of ceramic material is very small,has higher bonding strength than metal.And ceramic have high performance in tensile strength, compressive strength, elastic modulus and hardness,However,ceramic is "brittle" and difficult to machining,limits its application scope.

Over the last decade, due to the development and progress of martensitic phase change toughening technique,composite Technology and nano-ceramic,had made greatly improved for "brittle" of ceramics,its toughness and strength has been greatly improved,applied range is also expanding, such as the application as the faucet valve to be greatly welcomed. affordable,less water pollution, good wear resistance,good sealing performance,and improvements for the “brittle”,to make ceramic valve been widely used.Currently,most faucet had been used ceramic valve on the market.

Stainless steel ball valve

Stainless steel ball valve is high-tech content,some high-grade sanitary ware brand use laser technology processing irregular seven hole stell ball valve, as a new faucet valve for the newest product.Insiders think that this valve is suitable for poor water quality area.because it is not affected by water impurities or shorten service life.And steel ball valve handle have larger turning angle to control temperature accurately,ensure hot water can be flowed promptly and accurately to saving energy.

However, the cost of stainless steel ball valve is higher than other types,and production process requirements is much higher,suitable for poor water quality area.

Identification methods for valve.

"simple way" to identify faucet valve:

1.To feel if there is blocked feeling when you are turning off/on the faucet(if so,the valve is bad).

2.Turning off/on the faucet in half,the handle feeling of upper half and lower half is not different(just high-grade valve have this characteristic)

3.Good valve,you will feel very slight when you are turning off/on faucet.

4.Also turning off/on the faucet,to feel if there is oil damping feeling,blocking feeling,if no blocking feeling and with damping feeling,just buy it.
