Installing "Flexible Corrugated Copper Water Heater Connector"


These have 3/4" FIP fittings and a gasket (not cone) in them. Do I use teflon tape to connect to a 3/4" pipe nipple, after all, both are tapered. The watts connector I have offers no instructions, just "Do Not Overtighten" on the tiny tag. I think I may have cranked the hell out of one that eventually leaked. Not sure if I used tape or not on that one...

I have no experience with these, but someone recently created a thread about how he regretted installing one of these.

Do not use tape. Tighten them hand tight, then go about 180 more degrees. That should hold major amounts of water. Pressurize the system and check for leaks. Tighten as needed to stop any further water coming from the joints.

That was me! I've decided to try and get it to work and put off "doing it right" until the water heater craps out. No question, I'm never using compression or this type of connections again, all sweat from here on out.

Flex connectors will last for years if installed properly.

Doesn't a water heater installation require an earthquake strap anyway?

Installing "Flexible Corrugated Copper Water Heater Connector"


Earthquake straps? Not in GA. Not since my first wife walked out, now when she walks across a room=Earthquake! Don't know if we've ever had an earthquake in the 61 years I've been here. I install electric water heaters in my business. The only way I will use those flex copper tubes is if I'm running late in the day, I don't have something I really need in my trailer, and I can come back tomorrow to finish the job rather professionally. I've seen those flex pipes develop pin holes, usually within the bottom of the corrugation and on the outside of the bend --where the water flows against the tubing. David
