Had to rotate the hot water heater in it's closet as part of the basement remodel. Decided to replace the old gate valve with a new ball valve, and use 3/4" compression fittings to attach the new valve to the existing copper. Never worked with a compression fitting that size, and was worried about leaks at the fitting. Good news - no leaks at the compression joint.
Bad news, leaks just about everywhere else. Bought new dielectric connectors for the top of the water heater, fitted brass elbows to these to allow the s/s flex to attach with a single flowing bend. Leaks where the brass elbow attaches to the dielectric connector. Sealed with lots of wraps of teflon tape. Tightened VERY tight.
Nipple between the compression fitting and the ball valve - leaks.
Nipple between the ball valve and the S/S flex - leaks.
Only place we don't have leaks are at the compression joints, and the ends of the S/S flex which have a rubber washer. Didn't use tape at either of these spots.
All connections are made with plenty of teflon tape, and are very tight. Notice that the threads on the brass fittings are very sharp, and wondering if pipe dope, or a combination of dope and tape would provide a better seal with brass on brass connections. Haven't used dope in ages, and have never had this much leaking using tape.
Thanks!
