Difficult water heater connector leak


I recently replaced a leaking water heater connector, and had to tighten it down more than normal to get it to stop leaking. I'm guessing the lip of the male adapter (where the gasket of the connector seals) on the hard copper line might be chipped or eroded.
The line is holding now, but if it starts leaking, do you guys think it would be best to:
1) file down the lip of the male adapter until it is smooth, file off any sharp edges, so that it will seal better, or
2) cut off the male adapter, solder on a new one.

Difficult water heater connector leak


I'm confused:
What is the male adapter made of, what is it adapting from and to?
Gasket on what connector?
A picture would help.

I suspect it's a solder x compression adapter to use a cheater hose with...
and the 'gasket' is the compression ring.

OP: if/when it leaks in the future...
yeah, post a picture.

When you say where the gasket of the connector seals on the hard copper line, I'm guessing that the fitting on the hard copper line is not quite lining up with the male adapter.

If that's the case and if your area allows flex lines to the water heater, maybe consider the Watts stainless steel corrugated flex line.


See more info at: http://www.watts.com/pages/whatsnew/FFSS.asp

Though the picture shows connection to vertical copper lines, it would work well with horizontal copper lines as well. The flexibility of the line insures that the threaded fitting and gasket will seat properly. You will probably have to cut the copper line back a ways and solder a 3/4" copper male fitting, to allow installation of the corrugated line. This type of line comes in 12, 15, 18 and 24 inch lengths and comes with built-in dielectric sleeves, eliminating the need for separate dielectric unions. I installed one to our expansion tank and both connections were leak free from initial installation.

----------

If your area requires hard copper lines to the water heater, maybe consider installing heat traps on both hot and cold lines. The extra copper piping of the heat traps could allow some flexibility in proper alignment of the fittings and you would gain excellent, trouble free heat traps as well.


http://www.energycodes.gov/moodle/mo...iew.php?id=109

If you do install pipe type heat traps, remove any valve heat traps that you may already have. Pipe type heat traps don't restrict water flow or fail like valve type heat traps.

Maybe some options,

It is possible (albeit difficult) to just replace the gasket. Most of the time that's what causes the leak on the old flex lines when a heater is replaced.

Difficult water heater connector leak


Here is a diagram. The connector is a flexible copper line for hot water coming out.
Usually replacing the connector is a quick fix for me, I should have examined the lip of the adapter more carefully. It is holding for now...
