You have probably figured this out by now, but we had the same problem when we bought out house, complete with new glacier bay toilets. If you look inside the tank, if I remember correctly, there was a piece of some kind of plastic (might be clear, it was hard to see), that comes with the toilet and was getting in the way of the seal, making the toilet run continuously.
How do I adjust the water level in my tank? The directions in the booklet is confusing. I have purchased a Glacier Bay toilet from Home Depot.
The water in the tank keep running into the man-hole
Either the flapper in the tank is not sealing or the fill valve is stuck open, Take the lid off the tank and you can find the problem.
I have a flapless glacier bay toilet that keeps running, the mechinism has failed and I can't seem to locate a replacement. Home Depot does not sell the mechinism. Where can I purchase one?
