Today I went back on a call I completed three days earlier. The initial problem was: toilet not filling into the bowl. I knew that if we replaced the fill valve that would fix the problem. The solution was to do a minor rebuild on the toilet.
A minor rebuild on a toilet includes the fill valve, flapper and toilet supply line. A major rebuild consist of all the above, as well as, replacing the tank to bowl bolts and gasket.
Anyway. Yesterday I came back because the customer called and said it was filling automatically every so often. I saw that water was spilling past the fill valve and onto the float. This was causing the fill valve to come on automatically . So I replaced the fill valve at no charge.
Well, low and behold, the customer calls back again. Now I'm getting frustrated. He said it was coming on every two minutes. The flapper was not sealing properly. If I would have just looked at it more closely the first time, I would have seen a small defect in the flapper.
