How do I stop a toilet that keeps running?
A toilet that keeps refilling every few minutes has a leaky flapper 90% of the time. Drop food coloring in the tank, wait 15 minutes, and check the bowl — if the color shows up in the bowl without flushing, replace the flapper. It's a $8 part and a 10-minute fix.
Why is water pressure low at only one faucet?
Low pressure at one fixture is almost always the aerator or the fixture cartridge — not a house-wide issue. Unscrew the aerator (the little screen at the tip of the spout), rinse it, and try again. If it's a shower, the head itself may be limed up. Pressure issues affecting the whole house are different and need a PRV check.
