Greetings Plumbing Gurus!

I have a friend that has asked me a question, but I don't have the foggiest clue. If any of you can understand it and help us out, we would appreciate it! Thanks in advance:

My pressure tank and its feed line will be lowest point of my household water system. What sort of valve would you buy to put in line so I can drain the system? It will end up being lower that hot water tank, filters, etc. Of course they can all be relieved but I'd like a way to do same for pressure tank. I didn't realize the internal bladder is replaceable but I'd have to disconnect tank and turn it upside down. I may have to tee off the mainline but was trying to think of alternative.

Your pressure should have a boiler drain on it that you can connect a garden hose to. Usually it will be on the tank tee. If not then there should be a 1/2" or 3/4" plug for one. If not then I suggest plumbing a tee for a 1/2" or 3/4" boiler drain in the outlet plumbing of the tank, but you won't be able to totally drain the tank. That's why there should be one on the tank tee.
