MY moms elecric water heater in the garage is old. when I go to replace it I do not want to have to use all the brazed elbows the plumbers used when they put it in.
My choices are
1. braze on a threaded fitting on the hot and cold water lines and use threaded copper flex to the heater.
or
2. Don’t braze anything and use those big flex connectors that come with compression fittings- I see them for 3/4 in copper pipe
But do those big compression fitting work oK n the hard pipe copper lines?
Any experiences.
Just cause they sell them does not mean they are great.

The trick with compression fittings is a little lube. As in pipe dope, make a world of difference.
Nothing wrong with the fittings as they are used all over the place.
THEY NOW MAKE HWH FLEXES WITH SHARK BITE ON ONE END THREADED ON THE OTHER
I ran about 75' of 3/4 copper water line through our telecom room with nothing but compression fittings. I couldn't use any sweat fitting because of all the cable in trays and equipment that doesn't like open flame and heat.
That was six years ago and we haven't had the first drip of a problem.

It has been there for 5 years now, and my phone hasn't rung yet. Nore has it rung for the schdl 40 pvc we ran for a loop off our chilled water line to a water cooled condenser unit in that same telecom room. The 3/4" copper with compression fittings is for domestic water to the same unit as a back up to the chilled water.
That just means that you are getting closer to the day it does leak. With luck it will be 1 day after you retire. LOL
Seriously, doesn't it strike you as stupid to be running water through a room that is full of critical electronics? Every time I see water lines in a server room, I cringe.
