asihi Posted April 29, 2010 Report Share Posted April 29, 2010 I did a new construction townhome today. At the water heater, instead of finding dielectric fittings at the supply lines, the plumber used brass compression fittings. Is this type of fitting allowed or is this a new type of fitting? Thanks for your help. Tony Click to Enlarge 25.57 KB Quote Link to comment Share on other sites More sharing options...
Terence McCann Posted April 29, 2010 Report Share Posted April 29, 2010 Typically the nipples going into the tank are dielectric. Quote Link to comment Share on other sites More sharing options...
hausdok Posted April 30, 2010 Report Share Posted April 30, 2010 There's no need to use a dielectric fitting if you're going to use brass between the steel and the copper and I don't think there's going to be any steel-to-copper contact there.

I don't know what the ruling is, but I know I've used those compression fittings on 1/2" copper and they are fine. Better than solder for hooking up a woodstove water jacket.I don't think I'd trust the new push and twist fittings, but have never used them, either.
