No matter what appearance the push-type faucet has, whether it has two handles for hot and cold water or only one handle for controlling hot and cold water at the same time, it works according to some basic principles. The following is a description of how to open a press faucet and repair dripping:

Required tools: Use these tools to deal with push-type taps - screwdrivers, penetrating lubricating oils, slip joints or adjustable wrenches and pads to be replaced.


Repair step 1: Remove the handle and check the parts of the faucet. Remove the packing nut using a large-scale pliers or adjustable wrench, taking care not to leave scratches on the metal. Rotate the spool or shaft in the same direction that you turned it when you turned on the faucet to unscrew them.


Repair step 2: Remove the screws securing the washers. If necessary, use penetrating oil to loosen the screws. Check the screws and valve plugs and replace them if damaged.


Repair step 3: Close the water supply and remove the small screw on or behind the faucet handle to remove the handle attached to the faucet body. Some screws are hidden under metal buttons, plastic buttons, or plastic tabs, which snap or screw into the handles. Just open the button and you will see the handle screw on the top. If necessary, use a penetrating oil such as WD-40 to loosen the screws.


Repair step 4: Replace the old gasket with a completely new one. New washers that almost perfectly match the old washers will generally make the tap no longer dripping. You also notice whether the old washer is beveled or flat and replaced with the same new washer. Gaskets designed for cold water only expand rapidly when there is hot water passing through it, blocking the outlet and slowing the flow of hot water. Some washers work in both hot and cold water, but you have to make sure that the gasket you bought for replacement is exactly the same as the original one.


Repair step 5: Fix the new gasket to the valve plug and reinstall the parts in the faucet. Rotate the valve clockwise. After the valve plug is in place, reinstall the packing nut. Be careful not to let the wrench scratch the metal.


Repair step 6: Reinstall the handle and put the button or disc back. Re-open the water supply and check for leaks.

1.Check the tap valve seat

    If you change the washer and the faucet still drips, there may be a problem with the faucet seat. A damaged gasket may cause the faucet seat to become worn out by the metal plug, or the deposition of chemical in the water may form a residue that will not allow the gasket to fully compress with the seat.

    How to repair a broken faucet seat? Of course, you can replace the entire faucet. Another option is to simply replace the faucet seat. If you have the right tool, known as a seated spanner, it is a simple matter to remove the old seat. Insert the valve seat spanner into the seat, and then pull it counterclockwise. Once you have removed the old valve seat, make sure that the new valve seat you bought is exactly the same as the original one. If the seat cannot be removed, insert a seat cover that slides into place on the old seat and provides a seal. Two types of seat roller or sanders that can flatten worn seats. Another option is to use a seat roller or sander, an inexpensive tool that flattens worn seats. Be careful not to use too much time or use too much force when using this tool because the valve seat is made of soft metal and you can easily wear it off too much.

    When using a sander, first remove the faucet valve and insert the seat roller down into the seat in the faucet body. Rotate the tool clockwise several times with moderate force. Then use a cloth to wipe off the metal chips that have fallen off the valve seat.


2. Check the tap sealing ring

   Drips occur when the faucet is closed; leaks occur when water flows through the faucet. If you see water pouring out of the handle, your faucet is leaking; the first thing to do is to make sure the tap nut is tight, but be careful not to scratch the nut with a pliers or wrench.

   Here are the tools you need to replace the tap seals: adjustable wrenches, replacement faucet seals, petrolatum.

   If you find that the cause of the leak is not a loose nut, you must replace the seal. The sealing ring of the faucet may be a tight seal consisting of one or more O-shaped rubber rings, or something like a string or a soft wire wrapped around the valve core under a packing nut.

When replacing the tap seal, follow these steps:

Repair step 1: Turn off the water supply and remove the three way faucet handle.

Repair step 2: Unscrew the packing nut and remove the nut and the old seal from the valve plug.

Repair step 3: Install a new seal. If you are using a linear seal material, wrap it around the spool. If it is a sealing material such as a soft wire, it will only wrap around the valve core. Before you reassemble the three way faucet, apply a thin layer of vaseline oil on the threads of the valve plug and the threads of the packing nut.


3.Check the tap the O-ring

    The three way faucet has one or more O-rings to prevent water from escaping around the outlet. If the o-ring is worn, you will see water flowing out at the bottom of the outlet each time you turn on the tap.

    The following are the tools needed to change the O-ring: Adjustable wrench, water joint tape, replaced O-shape.


Replace the O-ring:

Repair step 1: Turn off the water supply, turn it counterclockwise and remove the threaded coupling nuts that secure the outlet. Be sure to wrap the nut with tape to prevent it from being scratched by a pliers or wrench.

Repair step 2: After removing the coupling nut, lift the water outlet upwards and out of the outlet seat. Inside the outlet seat you can see the rings.

Repair step 3: Replace the problematic ring with a new one of the same size. Reassemble the three way faucet again.
