Why Is My Toilet Running by Itself in Cary?
Cary · October 2026 · Alex & Chris · From our service records

What we found and did
Alex and Chris found that the master bathroom toilet was running by itself because the flapper was allowing water in and the fill valve turns on when it's low, and the tank to bowl bolts were also a little worn down. In the half bath on the first floor, which had a recent leak and was completely gutted, they found a compression stop leaking behind the toilet. In the crawlspace, the water heater was 9-10 years old with no issues that they could see, and a prv appeared to be rusting bad and had leaked at some point but wasn't actively leaking. The hallway bathroom had no leaks and the plumbing was in great shape, and Alex and Chris provided options for all of the findings.
