Can 50 year old galvanized pipe leading out of a shower drain become corroded on the inside and slow water?
Question:a plumber said my 50 year old galvanized pipe generaly does not corrode on the inside. is this true. water in shower backs up. would replacing the galvanized pipe fix water back up problem. plumber sent roto roooter through pipe, but only temporarily fixed problem
Answers:
It can get debris buiilt up around the insides like the arteries of your heart does with cholesterol. Look for something at the hardware store that is safe to use on shower drains to get the build up to loosen up and disintegrate.
Maybe not but soap scum and other debris can collect on the particles inside the pipe. That will restrict the flow of water. Bye
The pipe might not corrode, but if you have hard water, you can get deposits on the inside of the tank from minerals in the water. In some areas, a hot water tank only lasts a few years because it gets plugged up with the mineral deposits from hard water. But if he sent a roto rooter through and it fixed the problem, even if only temporarily, then something else is causing it to back up. It sounds as though there may be a break in the drain line.
My house was built in 1937, we have had some problems with our galvanize pipes as well. We took the one off to the shower and it had brown gunk on the inside, kinda the color of rust, so we replaced it. and it's as good as new now. your lucky you got a plumber, We can't find one that wants to work on this old dump.
i recently replaced the entire plumbing in a friends 50s style home because the galv. lines were 90% blocked and these were supply . he had no water pressure until after the replacement now he cant turn them all the way on,so if pressurized lines can get this corroded imagine how bad drain lines can get. hope this helps
one person said you are lucky you have a plumber. I disagree with them,,YOU DONT HAVE A PLUMBER
when you say 50 and galvanized ,,what you mean is stopped up bigtime,,,this last weekend I replaced s trap on kit sink and put a rubber boot on a galvanized pipe,, the pipe was about 15% open at the elbow,,,turned water on ,,filled sink,,, no leaks ,,,but no drain either,,,,,next 4 hours cleaning out GALVANIZED PIPE,,,
YOU DONT HAVE A PLUMBER
YOU HAVE CORRISON SLOWING DOWN YOUR WASTE WATER
If a rotor router was sent through he line and it helped, then I guess it would be plugged, wouldn't it.
Galvanized pipe does indeed plug up and does corrode. If it's fifty years old, it may be time to replace it.
The next time have then go further out with the cleaner, it may be plugged up further out.
