Toilet Keeps Running
Water trickles into the bowl or the tank keeps topping itself up long after the flush. It's quiet, but it's often the biggest single water waster in the house. On a septic system, that extra water also overloads the tank and drain field, so fix it soon and keep up with septic tank service.
- Usual cause
- A worn flapper, a chain with no slack, a fill valve set so high that water spills into the overflow tube, or a refill tube pushed below the water line.
- Check first
- Lift the float. If the running stops, it's the fill valve. If not, it's the flapper.
