What is the reason for the tight tap switch?
1, too high water pressure: too high water pressure can not drive the valve core, which will lead to the tightening of the faucet switch. Just add a pressure reducing valve to the main valve of the water pipe.
2. Spool damage: the faucet spool is damaged and needs to be replaced with a new one. Friends who can't install can ask local professional masters to handle it at home. When replacing the valve core, be sure to turn off the main switch of the water valve at home.
3, faucet aging: the faucet will age after a long time, and the switch will rust. Add some engine oil and it will work normally.
4. Plug: There is something blocked at the plug. You can take the faucet apart to see if there is any blockage.
Above, I have analyzed the reason why the faucet switch is tight, hoping to help you.
