Came across a 3 basin restaurant style sink that I am going to use in my basement (homebrewing!).
I'm using CPVC to connect to this faucet but there was originally a short threaded black pipe nipple with washers that went into the faucet from the back side and then a female CPVC connection to the water supply. The black nipples were solid gunk & rust inside so I removed them.
Instead of going back with another black pipe connection, can I not just use CPVC male adapters straight into the back of the faucet?..is CPVC strong enough to make this connection and hold the faucet to the sink? It seems to hold (see pictures) but I didn't tighten it down very far, only did this as a test. It seems like there should be a locknut on the back side to hold the faucet in place and then the threaded plumbing fitting, but no one at the home center could help me find anything like this...should there be one?
