We are selling our house and the buyers inspector says that our drip pan for the water heater has to have a drain line to an outside wall.
I have heard rumors that this is a fairly new code and that it may not apply in this case.
Our home was built in 1999 and has the same water heater that came with the house. I am told that in 1999 the codes didn't require a drain. It was installed with a drip pan but the pan has no drain line. I have been told that our water heater and drip pan are part of a grandfather clause that says if the water heater and drip pan were installed before the code change that we are not required to have the drain line installed until such time as we replace the water heater.
My buyers inspector says that it installed incorrectly ( without a drain line) and now the buyer wants us to have a drain line installed.
My questions is this. Do the new plumbing codes require this or can I say no and have a leg to stand on?
