What should I do about a leaking toilet today?
Shut off the water supply valve behind the toilet to stop the leak. Check whether the leak is at the flapper, the flush valve, the toilet flange, or the wax ring, since a flapper-only fix can cost about $12 to $30 in parts. Call a licensed local plumber to confirm the source before agreeing to any work.
How do I know if I need a repair or a replacement?
A pro can fix common toilet problems such as the flapper, chain adjustment, toilet flange, flush valve, or wax ring for around $150. Ask the pro to explain whether the issue is a repair or whether replacing the toilet makes more sense. Get that distinction in writing before approving the work.
What should I check when hiring a plumber in Kansas City?
Kansas City licenses plumbing contractors locally and requires a city contractor license and a qualified supervisor. Missouri does not issue a statewide plumbing license, so verify the Kansas City Journeyman Plumber or Master Plumber certificate. Ask for proof of licence and insurance before work starts.
Does a toilet repair need a permit in Kansas City?
Replacing a faucet or other plumbing fixture is exempt from permitting, but the full exemption list is limited. Most other plumbing work requires a permit before it begins, and applications can be filed through the city's CompassKC online system. Ask your pro whether a permit is needed for your specific repair.
What to do next
- Close the toilet's shutoff valve and note where the water is leaking (base, tank, or supply line).
- Ask the pro for a flat-rate quote that lists parts and labor separately, with any service call fee shown up front.
- Verify the plumber's Kansas City Journeyman or Master Plumber certificate through the city's contractor licensing page.
- Confirm whether the job is exempt from permitting or needs a CompassKC permit before work begins.
