Why Does My Toilet Keep Running?
A running toilet wastes 200+ gallons a day. Here are the three common causes and how to fix them yourself in under 20 minutes.
1) A worn flapper that won't seal — an inexpensive part.
2) A fill valve stuck open or set too high — an easy adjustment or swap.
3) A cracked overflow tube — less common but audible when you lift the lid.
A running toilet can waste 200+ gallons per day. It's usually a 20-minute fix.
