How to disassemble and repair the household hot and cold water faucet?

1. Preparations.

Before replacing the faucet, first close the inlet valve. The inlet valve is located under the kitchen countertop. However, it is understood that if the valve is not closed tightly or can not be closed, it can be operated with water, but during the installation, the new faucet should be prepared in advance with raw material tape along the thread direction 7-8 times in advance (it is easy to seep water if it is less), and a large bucket should be prepared under the water pipe to receive water to prevent waste; In addition, when the valve cannot be closed, be sure to open the new faucet and other faucets to divert and decompress the pressure.

2. Disassemble the faucet.

1.Separate the inlet pipe and hose.

Use a wrench to separate the inlet pipe and hose first. The water inlet pipe in the bathroom is an open pipe, which can be shaken by hand, so you are afraid that it will break if you accidentally break it when disassembling it. Therefore, when disassembling, you should be especially careful, hold the water pipe with your left hand, twist the wrench with your right hand, and easily separate the two.

2.Separate the faucet from the basin.

Remove the faucet fixtures so that the faucet can be removed from the basin. But that's when the problem arises. The hose of the faucet has been used for a long time, so the hose has become brittle, and the fixing parts have rusted and cannot be unscrewed with a wrench.

3.Cut the interface with a saw.

It is difficult to operate due to the small space under the basin. Moreover, the glass glue between the washbasin and the countertop has long since failed, so the washbasin can be easily removed from the countertop. Once the basin is removed, the construction will not get in the way.

Then use a saw to cut off the rusty part that is difficult to remove, and the faucet is successfully removed.

We know that preparations must be carried out before disassembling the faucet, and there are some knowledge in the process of disassembling the faucet that we must learn. With the emergence of various faucet products on the market, we should consider all aspects before purchasing faucets, such as its material, function, shape, and so on. Faucets have a wide range of applications, such as star-rated hotels, homes, guesthouses, public places, hospitals and other places.

Therefore, it is also very helpful for us to master the relevant disassembly methods.

The procedure for disassembly is:

1. Turn off the main switch. Find the red and blue dots under the handle. Snap it open with your hand and reveal a small hole.

2. Use a flashlight to observe the hole to see whether a fixing screw inside is a cross or a slot, and use the corresponding screwdriver to loosen it.

A few brands of this screw have an inner square hole (e.g. Moen), which is a bit more cumbersome. When tools are not available, be careful not to damage the screw mouth with other alternative tools that can be removed.

3. When the screw is loosened, the handle can be removed.

Fourth, at this time, what you see is a large copper nut, after removing the nut with a movable wrench, you can remove the valve core of the faucet.

5. Observe whether the copper plane under the valve core is uneven or whether there are fine sand grains, and remove it.

The specific operation steps for disassembling the electric water faucet are as follows:

1. Loosen the plug wire screws that disconnect the power supply, and the wires can be removed.

2. Unscrew the inlet pipe joint of the faucet.

3. Unscrew the fixing screws at the bottom of the faucet.

4. Shake up and lift the faucet.

5. The outlet pipe of the rotating faucet can be disassembled.

3. Unscrew the fixing screws at the bottom of the faucet.

4. Shake up and lift the faucet.

5. The outlet pipe of the rotating faucet can be disassembled.

Method 1: Close the main water valve first, and then put the faucet handle with a red and blue mark of about 8 mm, buckle it down, loosen the fixing screw counterclockwise with a flathead screwdriver, take off the handle, use a live wrench to disassemble the valve core of the faucet, open the upper part of the gland with a wrench, and take out the ceramic valve core inside.

Method 2: Close the main water valve first, you can use a screwdriver to insert under the handle of the faucet, pry left and right, pry it on the side, take it slowly, and the force is even and stable, so that you can remove the valve core.

Method 3: Close the main water valve first, unscrew the blue cover on the right handle, loosen the screws inside with a Phillips screwdriver, take off the handle, and the valve core will be exposed, and then use a movable wrench to unscrew the valve core.

When you remove the spool, you will see a blue rubber ring at the bottom of the spool. It is generally customary to have a red rubber at the bottom of the left spool, while a blue rubber on the right spool. Therefore, when changing the valve core on the right, it is still necessary to use the blue rubber valve core, after the valve core is installed, the handle is plugged in, and the direction of the handwheel is adjusted.

Attach the screws and close the blue cap on the right, so that the new spool is replaced.

Various faucet disassembly**, teach you how to replace faucets.

Hot and cold water faucets are generally divided into single hole and duplex, and you will be given a single hole faucet installation diagram for your reference.

1. Close the inlet valve of hot and cold water;

2. Unscrew the two hoses connecting the hot and cold water pipes and the faucet;

3. Unscrew the big nut that fixes the faucet under the pool;

4. Remove the faucet.

It will not be inappropriate, and the general faucet is DN15 joint with hose. As long as it is a professional plumber, it will do. You didn't say anything about the location of the water leakage, so it's hard to say, generally the faucet is not closed tightly because the ceramic core inside is not tightly pressed by foreign bodies.

So it's not tight. Is it that you used cold water when you first installed it, and after a period of time you used too hot water, and then you still used both hot and cold water after changing the valve core. It should be a problem with the spool.

There are several kinds of valve spools of faucets, and the plastic spool was originally used, due to the large coefficient of thermal expansion of plastic, there is no problem when used on cold water, and this situation will occur when used in hot water. There is also a ceramic spool, as long as the spool is tightened, there is no problem with the seal. Hello, I do the installation, you are talking about the hot and cold basin faucet1, first connect the hot and cold water inlet pipe and the faucet, and the very simple hose thread can be transferred to the faucet water inlet hole 2, fix the faucet to the countertop, and there is an installation nut at the bottom of the faucet 3, connect the hexagonal nut of the faucet water inlet hose with the angle valve ---

First, turn off the pressure reducing valve or switch of the faucet for hot and cold water, then use a wrench to remove the two connecting hoses, and loosen the large nut fixed under the sink or washbasin with a pipe wrench, and then take out the faucet from the top of the sink or washbasin. The installation sequence is reversed, the key is to ensure the sealing performance of the hose and faucet connection, and secondly, to secure the large nut (not too loose, not too tight) under the sink or washbasin.

There is a red and blue chick under the handle, buckle it, a small screwdriver, unscrew it, unscrew the decorative ring, use a wrench to remove the ** that fixes the valve core, and take down the valve core. Then how to disassemble it, how to install it.

First handle, then gland, and then screw to remove the valve core, and it is finished.

In fact, the faucet is not so easy to install, so be very careful, 1 because it involves a leakage problem, in many cases we don't know the degree of bite inside;

Precautions before installation:

1. Arrange the water inlet pipes and joints according to the selected faucet products.

2 Pipe flushing (flushing out debris in the pipe) must be carried out before installing the product.

3 Install the product after closing the main valve (be careful not to touch the product).

4. Test after installation: 1) seal the connecting part, 2) hot on the left and cold on the right, and 3) whether it is installed firmly.

5 Test and debug OK.

6. Clean up the site, hand over to the user, and give a preliminary description of the use to avoid improper use.

Installation Notes:

1 Countertop Basin (Kitchen) Faucet Installation:

1) Generally, the height of the table is 80-85cm, and the water inlet pipe attached to the faucet is 35cm long, so the water inlet interface should be 55-60cm away from the ground level to avoid no margin when connecting. (The above is for reference only, and the water intake, drainage, and lamp line should be discharged according to the product hydropower circuit diagram).

2) The water inlet interface and the faucet water inlet pipe are generally connected with angle valves, which is convenient for faucet maintenance and replacement (no need to turn off the main switch).

3) The hole at the bottom of the faucet and the countertop should be evenly combined, and the gasket or gasket should have a certain amount of compression after assembly to prevent water leakage and loosening of the faucet body.

4) When installing, pay attention to the nut to lock in a quick installation way.

This is actually not difficult, and there are usually a lot of tutorials on the Internet. , you prepare a 10-12 inch live wrench, first close the main water valve at home, use the live wrench to remove the threads are right-handed, and the unloading is reversed is the opposite direction.

1. Prepare tools. It is necessary to prepare a flathead screwdriver and a 30 to 50 adjustable wrench, and then check the reason, and then close the main valve of the tung bucket to facilitate construction.

2. Separate the faucet. Insert the screwdriver into the hot and cold mark holes when the celery wheel is eliminated, then rotate it counterclockwise about three times, and finally grab the handle and pull it up forcefully to separate it.

3. Replace parts. Place the adjustable wrench in the hexagonal position, then rotate counterclockwise to remove the ceramic core for inspection, if it is damaged, you need to replace the valve core, and finally install it.

1.Turn off the water source: Before disassembling the faucet, the water source must be turned off to avoid damage and waste caused by the water flow.

2.To remove the faucet: Use a wrench or wrench pliers to unscrew the nut of the faucet, then remove the faucet from the pipe.

3.Disassembling the inside of a faucet: Taking the faucet apart usually requires removing the handle and other parts of the faucet. These parts may need to be disassembled with a wrench or screwdriver for transport with the closed key.

4.Inspect the parts: Inspect the parts inside the faucet for damage or wear. If there is, it needs to be replaced.

5.Replacement Parts: Replace damaged or worn parts as needed. If the gasket needs to be replaced, it can be removed and replaced with a new one.

6.Assemble the faucet: Reassemble all the parts onto the faucet and tighten the nut with a wrench or wrench pliers.

7.Turn on the water source: Turn the water source back on and check that the faucet is working. If there is a water leak or other problems, it is necessary to re-inspect the car beam for inspection and repair.

First close the main sluice of the water pipe, and then buckle the part with red and blue dots under the faucet handle, and then you can see a small hole. Then determine the model of the screwdriver through this small hole, use the corresponding screwdriver to unscrew the screws in the small hole, then remove the handle, and then use a wrench to remove the big nut on it, and then take out its valve core for repair.

How to choose a faucet.

1. Choose a brand with good quality.

When choosing a faucet, the first thing to pay attention to is the choice of brand, and it is best to choose some high-quality brand products on the market. If you choose an imported faucet, you need to pay attention to whether the brand nameplate is marked on the product during the observation period. However, if you choose a domestic brand, it is best to ask the seller to provide the corresponding product certificate, and pay attention to the relevant labels of the product, such as name, address, etc.

In addition, when choosing a faucet, it is also necessary to look at how the dealer's after-sales service is.

2. Weigh the test switch.

In the process of choosing a faucet, most of them will weigh some of it, and basically people will do this kind of thing. Generally speaking, the heavier the faucet with a similar appearance, the better the quality.

At the same time, when selecting, we can also flip its switch to see whether the switch in each part is flexible and firm enough, and when pressing the switch, whether it feels soft. If it is very laborious during the opening and closing process, it means that the assembled structure is not up to standard, and this kind of faucet is prone to leakage after long-term use.
