How to solve the problem of opening and leveling the valve seat of faucet?
If you change a gasket, the faucet still drips, it may be that there is something wrong with the faucet seat. A damaged gasket may cause the faucet seat to be worn by the metal valve core and become uneven. Perhaps the accumulation of chemicals in the water may form residue, which makes the gasket unable to completely press against the valve seat.
How to repair a broken faucet? Of course, you can replace the whole faucet. Another option is to just replace the faucet holder. If there is the right thing - called a seat wrench - removing the old seat is a very simple job. Insert the seat wrench into the valve seat and turn it counter clockwise. Once you remove the old valve seat, please acknowledge that the new valve seat you bought is completely the same as the original one. Assuming that the seat cannot be removed, insert a seat sleeve that slides into the proper orientation of the old seat and supplies the seal. There are two types of seat rollers or burners that can flatten worn seats from the beginning.
Another option is to use a seat roller or grinder, a cheap way to flatten worn seats from the beginning. Be careful not to use too long or too much force when using this thing. Since the valve seat is made of soft metal, you can easily wear it off too much.
When using the grinder, first remove the faucet valve core, and insert the seat roller downward into the valve seat in the faucet body. With moderate force, rotate the object clockwise several times. Then use a cloth to clean the metal chips falling off the valve seat.
