If a vacuum breaker is not integrated into your plumbing system, screw a hose-type vacuum breaker on the hose threads before you connect the garden hose. Hose-type vacuum breakers are available at hardware stores. This prevents a siphon from developing and drawing chemicals or waste into the drinking water supply if the hose gets accidentally left in (submerged in) a container with cleaning chemicals or contaminated, un-potable water.
Check for leaks. The faucet may leak from the replaced faucet tip if the seal is not as good as it originally was.
Pull the tape tightly around the threaded area of the faucet, being careful not to let extra tape overhang the area where the water exits the faucet, as it may impede the flow of the water.
