Repairing Running Toilets & Weak Flushes

A constantly running toilet can waste over 200 gallons of water per day. We replace deteriorating flappers, worn fill valves, flush towers, and trip levers to stop ghost flushing instantly.

Wax Ring Seal Replacement & Toilet Installation

Water pooling around toilet bases indicates a blown wax ring seal or loose closet flange bolts. We reset toilets with heavy-duty wax rings, new brass closet bolts, and install modern high-efficiency toilets cleanly.

Frequently Asked Questions

Why does my toilet keep running after flushing?

A running toilet is usually caused by a warped flapper that fails to seal, a faulty fill valve that doesn't shut off, or an improperly adjusted float height.

What causes water to leak around the base of a toilet?

Water leaking around the toilet base indicates a blown wax ring seal, a cracked toilet bowl, or a damaged closet flange beneath the toilet.

Can a toilet clog cause other drains in the bathroom to gurgle?

Yes, if a main drain or branch line is blocked, flushing the toilet forces trapped air up through nearby shower or sink drains, causing gurgling sounds.

How much water does a modern high-efficiency toilet use?

Modern WaterSense high-efficiency toilets use 1.28 gallons per flush (GPF) or less, compared to older toilets that used 3.5 to 5.0 GPF.

When should a toilet be replaced instead of repaired?

If the porcelain bowl or tank has cracks, if internal components fail repeatedly, or if the toilet is outdated and uses high water volume, replacement is recommended.
