How do I stop my toilet from running constantly?

The most common cause is a worn flapper that doesn't seal properly. To test, put food coloring in the tank — if it appears in the bowl without flushing, the flapper needs replacement. A plumber can diagnose and fix the issue in under an hour.

Why is there water around the base of my toilet?

Water at the base usually means the wax ring seal has failed. This requires removing the toilet, replacing the wax ring, and resetting the toilet. It's not a DIY job — an improper seal causes sewer gas leaks and subfloor damage.

How long do toilets last before needing replacement?

The porcelain itself lasts decades, but mechanical components (flappers, fill valves, flush valves) typically need replacement every 5–10 years. If you're replacing components frequently or the toilet was installed before 1994, consider upgrading to a water-efficient 1.28 GPF model.

How much does it cost to replace a toilet?

Total cost for a new toilet including parts and labor ranges from $300–$800 for a standard toilet replacement. Higher-end models (comfort height, dual-flush, bidet seat compatible) can push the cost to $1,000+.

Can I install a toilet myself?

Flapper replacements and tank component swaps are DIY-friendly. Wax ring replacement, floor flange repair, or full toilet installation is best left to a licensed plumber to ensure a proper seal and no leaks.

What is a comfort height toilet?

Also called ADA-height or right-height toilets, these have a bowl height of 17–19 inches vs. the standard 15 inches — making sitting and standing easier, particularly for seniors and taller individuals.
