Then wrap the inlet pipes with Teflon tape to ensure a watertight seal.
Connect the supply lines to the inlet pipes on the faucet, wrap Teflon tape around the shutoff valve connections, and connect the other ends of the supply lines to the shutoff valves.
Otherwise, the air exhauster is not necessary, and the air inlet (4) connecting with the high-pressure clean air is arranged in the air inlet pipeline.
The above measures can effectively reduce the problems caused by the water inlet pipe.
