Leaking Toilet Repair in Northwest Indiana

Water around the base of a toilet is a wax seal problem. Water around the tank is a gasket or fitting issue. Either way, Downing Plumbing fixes leaking toilets throughout Lake, Porter, and LaPorte County — before the floor takes damage.

LEAKING TOILET REPAIR

Where the Leak Is Tells Us What the Fix Is

Water on the floor around a toilet has a few possible sources. A leak at the base — especially one that appears when you flush — almost always means the wax ring seal between the toilet and the floor flange has failed. This is often accompanied by a toilet that rocks or moves when sat upon, which breaks the wax seal over time. Left unaddressed, a wax ring leak will damage the subfloor and can cause significant water damage over months.

Water appearing around the tank can come from a loose tank-to-bowl bolt, a deteriorated tank gasket, a cracked tank, or condensation on a cool tank surface in humid weather. Supply line connections are another source — the braided supply line from the wall shutoff valve to the toilet tank can crack or the connections can loosen over time.

Downing Plumbing locates the exact source of a toilet leak, repairs or replaces the failed component, and inspects the subfloor for moisture damage before completing the job. A leaking toilet that's been going on for a while may have caused more damage than what's visible — we'll let you know what we find.

Fixing a Leaking Toilet

We find the source, fix the cause, and check for secondary damage — all in one visit.

1

Locate the Leak Source

We dry the area, observe where water appears during a flush cycle, and inspect the base, tank, and supply line to pinpoint the origin.

2

Assess the Flange

If the base is leaking, we remove the toilet and inspect the floor flange for cracks or damage that must be repaired before re-setting the toilet.

3

Repair the Leak Source

Wax ring, tank gasket, supply line, or flange — we replace the failed component properly so the fix is permanent, not temporary.
