Galvanized drain pipe precaution

+9
Answered
I have a galvanized drain pipe for kitchen and garbage disposal which had a hole due to corrosion and I fixed it using a clamp. A bigger task is to replace them with PVC but until then I would like to know which food/liquids I should avoid dumping in the sink to increase its life.
Are vinegar, bleach, baking soda things that I should avoid?

    At thispoint it really won't make much difference fretting over what goes down the drain, unless it is industrial acid. The pipe is shot. A bit of this or that from your kitchen will not suddenly change your situation drastically. Plan for your pvc days sooner than later.

    You must be in a pretty old house. PVC is today's answer to drainage. Our old house had what is called Orangeburg that we replaced with PVC. As far as avoiding this stuff if you are fixing the pipe. I think that these can be caustic items if undiluted. Recommendation is to get it replaced as soon as possible or you might get an even bigger problem.

    Common household liquids should not harm the pipe. Change to PVC pipe as soon as possible. The old pipe is a problem waiting to happen again. Clamps a pipe tape only go so far.

    All the things you mentioned are actually accelerating the decomposition of this type of pipe.You have to get the old pipe replaced as soon as possible!

    Agree with Jonchip they are beyond worrying about what you put in them. They are thin other than the rust inside slowing the flow anyway. Time to replace with pic & not have the problems you're having or going to have.

    If you want to solve the problem and not add to it. install the PVC. In the end it is going to be cheaper than patching , You can continue to patch or you can do it once. I know you are looking at expense., The pipe is finished and served its duty
