When I flush the toilet it flushes just fine, but it doesn't fill again. You have to close the wall valve and then open it up again to fill the tank. Is this a problem with the valve or the internals of the tank? Thanks
Check your fill valve (inside the tank) first. If it appears to be working properly, turn the water off outside the house, drain the tank, take the filler tube ( from the valve to the bottom of the tank on the outside) loose at the valve. Remove the valve and inspect for obstructions, such as calcium and or lime deposits. You may need to replace the valve as they will occasionally wash out over time. Reverse this process to put everything back together, and be sure to wrap the male threads on the supply line (pipe sticking out of the wall) with teflon tape.
