got another low pressure today...
jammed a screwdriver down the dielectric, jiggled it around to clean it out.
Both hot and cold. I put the water heater in Dec. 1996.
Considerable amout of loss in pressure in hot.
Unless its commercial, or on demand, i no longer use em for this reason.
Am i the only one who feels this way
I know that all three of you guys know what your talking about, but like
the first thing I learned in school was that dissimilar metal thingy. I've
also witnessed the dielectric union problem, but won't the "copper directly
to steel" cause problems too? I think those insulating nipples work just
fine (though they add about $6.00!).
When I can get away with it, I'll use copper adapters. They seem to pose
less of a problem. However, if the job is being inspected, the inspector
usually will want to see dielectric unions. If I have to use them, lately
I've been experimenting with brass nipples to see if this condition is
better or worse. I guess I'll know in a few years.
Thanks for the info, Ned. I haven't done many with brass nipples. I guess I
won't in the future. Lately I've been using dielectric nipples that are
coated on the inside...when I can find them. They don't seem too plentiful
here at the Jersey shore.
you don't ground your electric to the plumbing. you bond the plumbing with
that piece of copper.
ask an electrician you know who really knows his stuff. brass verry
dissimilar metal and will produce
yes it is.
I was told that brass had zinc in it.
That bronze is basicly brass without the zinc.
I have noticed that old brass fittings/ pipe if very weak sometimes.
I could squish it with channel locks.
I think there might be a connection.
we have a lot of iron in our water, it is quite dissimilar from copper.
We go through a lot of hot water tanks.
i have NEVER pulled an anode rod that was not seriously peppered with
Yes, that's electrolysis. I used to think the same as you, that brass
would cause a problem. I found out, and was humbled in the process, that it
ain't true. In a situation with electrolysis, it wouldn't be the brass
that'd rust; it'd be the steel tank.
mike thank you for just making my point agian.
Go back and read what i said.
Ask yourself why tanks come with anode rods in them.
Brass is close to copper but the zinc in the brass is not good.
Bronze would be better.
Why does TACO make a bronze circultor?? hmmmm??
