Things to Keep in Listen
An important thing to call back is that PTFE tape should not be used when connecting PVC fittings or valves with a female person (FPT) thread. If the tape is used on female connections, a wedging action can occur which volition cause major stress on the articulation during assembly.
PTFE record does not guarantee a leak gratuitous connection. Make sure you always inspect the connections with h2o pressure level to confirm that the connectedness is not leaking.
Knowing how to correctly wrap PTFE tape is the cardinal to easy and stress free installations. Having specific tape sealants colour coded for different applications makes it even easier. Book marking this simple guide as your become-to the adjacent fourth dimension you need to properly wrap a plumbing fixtures, peradventure even show a friend how to properly use the sealing tape.
