Why does my toilet keep running after I flush?

A running toilet is usually caused by a worn flapper that doesn't seal properly, a faulty fill valve that doesn't shut off, or a float set too high. The flapper is the most common culprit — it's a rubber seal at the bottom of the tank that deteriorates over time. This is a straightforward repair that stops wasted water.

Why does my toilet clog frequently?

Frequent clogs can be caused by a partially blocked drain line, an older low-flow toilet with inadequate flush power, too much toilet paper, or objects lodged in the trap. If plunging provides only temporary relief, the issue may be further down the drain line and needs professional clearing.

What causes a toilet to leak at the base?

Water around the base of the toilet usually means the wax ring seal between the toilet and the floor flange has failed. This allows water (and sewer gases) to seep out during each flush. The toilet needs to be pulled, the old wax ring removed, and a new one installed. This also requires checking the flange for damage.

What is a comfort-height toilet?

Comfort-height toilets sit 17-19 inches from floor to seat, compared to the standard 15 inches. The extra height makes sitting down and standing up easier, especially for taller people, seniors, and anyone with mobility issues. Most modern toilets are available in comfort height and meet ADA requirements.

Can a toilet cause water damage to my floor?

Yes. A failed wax ring, a cracked tank or bowl, or a faulty supply line can cause water to seep under flooring without being immediately visible. Over time, this can rot subfloor, damage joists, and create mold. If you notice soft spots around your toilet, discoloration, or a sewer smell, call a plumber promptly.

Should I replace both toilets in my home at the same time?

If both toilets are the same age and you're already replacing one, it's often more cost-effective to replace both in the same visit — you save on the service call fee. Newer toilets use significantly less water (1.28 GPF vs 3.5+ GPF for older models), so the water savings add up quickly.
