How to repair a broken faucet?

If the faucet is controlled by a main inlet valve, close the main valve. When the hot and cold inlet pipes are separated, then close the corresponding two valves. Specific steps for repairing leakage from hot and cold water faucets; Use a flat-mouth screwdriver to open the accessory "01 hot and cold mark (handle fixing screw hole plug)"; Use a flat-mouth screwdriver to insert the handle into the handle to fix the screw hole plug (hot and cold standard hole), and turn the screwdriver counterclockwise (left-handed) about 3 times; Grasp the faucet handle with your left hand, dial it upwards hard, and at the same time use the rear handle of the screwdriver (it must be made of non-metallic material, otherwise it will damage the outer surface of the faucet) and gently tap it upwards, so that the accessory "02 water outlet handle" is separated; Counterclockwise (left-handed) fitting "03 end cap", the end cap is separated from the main body; Place the beginning of the movable wrench in the hexagonal position of the accessory "04 core tightening hexagonal sleeve", adjust the size of the opening of the movable wrench, rotate counterclockwise, remove the ceramic valve core for inspection, if it is intact, clockwise (right-handed), and tighten the upper strength; If damaged, replace the spool with a new one.

Replace the accessories "03 end cap", "02 water outlet handle", and "01 hot and cold label (note that red represents the hot water side, and blue represents the cold water side)".

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.

Use a flashlight to observe the inside of the hole, see if a fixed 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.

When the screw is released, the handle can be removed. At this time, you see a large copper nut, and after removing the nut with a large wrench, you can remove the valve core of the faucet. Observe whether the copper plane under the spool is uneven or whether there are fine sand grains, and remove it.

Remove the rubber seal on the flat surface and observe for damage. Generally speaking, the integrity of the hot and cold faucets is good and the reliability of use is high. Therefore, after opening, it is often impossible to find obvious problems, at this time, it is just to change the valve core.

Finally, install it in reverse according to the above procedure.

First of all, you need to turn off the main switch, find the red and blue dots under the handle, buckle it open and reveal a small hole; Use a screwdriver to loosen it; When the screws are released, the handle can be removed; If you see a large copper nut, you need to remove the nut with a large wrench, and you can remove the valve core of the faucet; Observe whether there are uneven or fine sand particles on the copper plane under the valve core, which needs to be cleaned, and remove the rubber seal on the plane to observe whether there is any damage. Because the integrity of the hot and cold faucet is good and the reliability is high, only one valve core needs to be replaced.

Supplementary knowledge: bathroom faucet repair methods.

1. It can be carried out according to the above faucet maintenance process, the main difference is that the bathroom has a drain plug that can be ejected and connected to a knob or plug on the old faucet through a connecting device.

2. Before removing the old faucet from the pool, there should be one or two places on this connecting device that can be easily removed from the faucet, and it can be removed, of course, when installing the new faucet, it is also necessary to reconnect the drainage connection device to ensure the subsequent use.

3. The faucet on the bathtub is also the same operation procedure. Turn off the water supply, remove the faucet handle on the side of the tub, and remove the old faucet from the back. If you have an old sprinkler tube, just unscrew it from the pipe in the wall.

The hot and cold water faucet is repaired as follows:

Turn off the main switch, find the red and blue dot under the handle, and buckle it open, revealing a small hole; Observe the hole, see whether the fixing screw is a cross or a slot, use the corresponding screwdriver to loosen it, when there is no tool, use other alternative tools that can be disassembled, be careful not to damage the screw mouth; When the screw is released, the handle can be removed. What you see is a large copper lead sensitive nut, after removing the nut with a large wrench, you can remove the valve core of the faucet; Observe whether the copper plane under the valve core is uneven or whether there are fine sand particles, clean it, take out the rubber seal on the plane and take the hall ring to observe whether there is any damage, the integrity of the hot and cold faucet is good, the reliability of use is high, and the obvious problem is often not found after opening, that is, just change a valve core.

The electric hot water faucet light is not lit and the water is not hot:

1. The light is on and the water is not hot. Generally, the heating tube is damaged and can be replaced.

2. The light is not lit and the water is hot. Generally, the indicator resistor is damaged and needs to be replaced.

If it is a new machine, check the waterway to see if the water pressure is low or whether there is a wrong circuit wire; If it is not a new machine, then it is thermal damage and can be replaced.

Precautions. In addition, after each use of hot water, pull the handle to the cold water position and stay for 5 seconds before turning off the water, which can effectively prevent thermal damage and prolong the service life of the machine.

Due to the low probability of failure, it is not required to master the maintenance for the time being; If there is a first type of failure, or if it is a newly installed machine, it is 100% not a problem of the machine rental hole lifter itself, but a problem of waterway or circuit.

In addition, after each use of hot water, pull the handle to the cold water position for 5 seconds and then turn off the water, which can effectively prevent thermal damage and prolong the service life of the machine.

How to fix a broken water heater faucet
