weakestlinkGalvanized Iron Pipes Corroded
I am getting slow leaks where the old water intake pipes are beginning to rust through. I consulted with a plumber who said that the situation is like a deck of cards. The pipes are so brittle that he could be working on one section and go to turn the union and another section may break. It sounds like it may be expensive, especially if the pipe breaks off up inside the wall. Is there a quick, easy fix for this, like a spray sealant similar to Flex Seal (the handyman in a can as seen on TV)? I looked in the local hardware store and they just gaped at me when I asked for plumbing sealant.

Bob FlemingSorry, but I don't know of any quick fix for rusted galvanized pipe. And replacing with more galvanized steel is a laugh! Some places allow PVC to be used for the house incoming pipe underground, and there may be better materials such as PEX.
Inside a house the galvanized hot water pipe usually goes first, and if it is under a concrete slab, it can be an expensive mess when it does go. Copper is no better under concrete.

SparkyWeakestlink,
Bob nails it. I'd look at going with PEX plumbing. It can be fished into walls like electrical wiring so there would be less disruption to your house. You could possibly drain the old plumbing and leave it in place once you get the PEX in.
Galvanized supply lines are good for 30 years or so, if yours are older they are a major leak waiting to happen. Sorry for the lousy Christmas gift.
