Does pipe dope work when the pipes are galvanized on plastic? I have a
plastic connector that needs to go on old galvanized for a temporary repair
and I was wondering if pipe dope would seal the galvanized pipe threads
sufficiently if the female end was plastic.
Well I'm definitely sold on pipe dope over teflon tape. The stuff I used
worked like a charm, had to torque the pipe down less to seal it and that
will make it so much easier when I finally repair it for good.
After working with PEX now for about 4 months I'm on the fence as to whether
or not it truly is a better system over copper. I know the copper snobs
will all yell "I told you so" but I think with PEX the deal is that you have
to go all or nothing and you have to pick the system that will work for you.
So far the Zurn system isn't panning out too well.
As a general rule you never use a PVC female on a male galvanized
pipe. It will split before it seals. Put a metal coupler on the pipe
and use a PVC male adapter. Dope the metal to metal and use teflon on
the male adapter into the new coupler.
Yes you can if you do it properly.....first put teflon tape on the
female thread. This done in the same direction as the thread ((two
layers thick). Then cover this with a high quality pipe dope....not the
convience store quality crap.Do not overtighten.
