Greetings txmarti: Your best bet would be to find a valve that fits your tank. Any attempt to reduce the size of the threads on the valve would probably ruin it. You may be able to enlarge the hole in the tank slightly by grinding the hole a little larger using a die grinder. Most people don't have a die grinder at their disposal. Chipping away the porcelain with a any sort of tool is totally out of the question. the porcelain is very brittle, and would surely break. Good luck! Tom R

Dear Valued Customer: Thank you for your question concerning 2 in. Flush Valve Replacement Kit. The toilet is turning off and on because the tank is not holding water. This problem may be resolved by removing the refill tube from "Inside" the overflow pipe and attaching the tube to a clip to hold it onto the overflow pipe. In some cases the flush valve lock nut may not be tight enough and can cause water to seep into the toilet bowl.

First verify it is the flapper and not the tank seal that is leaking. Turn off the water. Flush toilet and hold lever open to drain all water down to the level of the flapper. Close lever and allow flapper to drop onto its seal. Add dye to remaining water. Check for dye in bowl. If there is then your problem is the tank seal. Flush valve needs to be removed and either the seal replaced or entire flush valve replaced with its included seals. If there is no evidence of dye in the bowl then it is your flapper that is leaking. Replace the flapper.
