1. The old valve core must be removed to measure the size, which is uncertain.
Please send pictures to customer service to avoid buying mistakes and delaying time
2. Be sure to figure out whether the valve core is a water distributor valve core or a cold
Thermal adjustment switch valve core
3. If you change the valve core, continue to drip or rotate the valve core handle
The flowing water may also cause a leak in the internal pipeline of the faucet.
4. The faucet is leaking from zinc alloy material, and the faucet is basically damaged.


Note: Save the old valve core first after removal
Close the sluice when disassembling this valve core
If you are not sure about the size, please contact customer service
The water leakage after installation is the sealing ring at the bottom of the valve core
It is not sealed well with the faucet, the bottom is right
Just tighten the cover with a wrench


Note: Slight error in manual measurement will not affect installation
