Unvented Undersink Water Heaters. For D.I.Yers.

Compression fittings have a place, they are also something I would not use unless readily accessible. 

A plumber once told me that they are not permitted to be used where they are inaccessible. In other words, the situation is just like MF JBs.

I have never found one that correctly installed has leaked. They are a fit and forget fitting. Also the maintenance free electrical connectors are a con just to boost profits. I have never found self loosening screws in junction boxes or wiring accessories. Fit correctly and forget.
