Can you connect pvc to an old galvanized drain pipe. it drains fron a shower.can galvanized become corroded?
Question:
Answers:
Yes, Since it comes from a shower I would assume that it is 2" galvanized (They call it Durham when its for a drain)
It can be a little tricky to cut galvanized pipe.
A Reciprocating saw would work great but if you shake the pipe too much you might cause a leak so be really careful. Also there is the cost for the saw.
I used to use a hacksaw when I first started plumbing (no wonder plumbers died early!) You could do it though. Get extra blades.
2" galvanized and 2" PVC are the same size, so use what they call a " no hub" mission coupling. Frenco fitting are not code in some places. You don't want to cause a problem for your self in the future.
Yes Galvanized pipe does corrode and clog up .
easyeric… makes a really good point grinders are easier on the pipe. If you have one use that.
sure cut of the galvanized pipe with saw all, get a firmo, which is a rubber boot to make the connection from the galv. to the new pvc, and start glueing, and yes galv. corrodes alot and blocks the passage
Yes you can.. if you go to any hardware store you can get adapters to change the size and fit into the galvanized pipe.. and yes galvanized pipe can rust.. just takes longer and deppends on how hard your water is
the galvanise process makes it hard to corrode. there is a fitting made that goes between, PVC and a galvanised unit, but I confess, I can't remember just what it is called
Yes you can do this by using "fernco coupling" found at any decent hardware store or plumbing supply. The easiest method of cutting the galvanized is by using a reciprocating saw. If the pipe is severely corroded I would advise to just replace the drain completely w/ pvc. Just be careful not to damage the shower pan... be gentle :) It can come out with minimal effort.
Good Luck
I find angle grinder more gentle for cutting the galvanized.
Galvanized pipe is legal for drainage under certain conditions.
It's best you replace it. Those old Durham fittings used were always hard to work on.
Replace if you can, otherwise, use a cantex, ct, or Fernco adapting coupling to tie on to it.
sure just buy galvanize to pvc adaptor
sure... Yes and yes
Yes you just need an adapter. Talk with you local hardware dealer when you go to get your parts.
Yes galvanized pipe is not invincible. It is only resistant and eventually will need to be replaced.
