Olathe, the Johnson County seat, has an established core around downtown and a lot of newer construction spreading south and west.
What plumbers run into in Olathe homes
Much of Olathe was built from the 1990s on, so many calls are water heaters reaching the end of a 10–15-year life, sump pumps in finished basements, and fixture swaps.
Closer to downtown and in 1980s–'90s neighborhoods, look for gray polybutylene supply lines — a planned repipe beats an emergency one. Olathe runs its own water utility, so meter-side issues go to the city.
Common plumbing calls in Olathe
- Leaking or burst supply lines
- Slow or backed-up drains
- Water heater repair and replacement
- Toilet, faucet, and disposal swaps
Olathe has both: older houses often still have sections of galvanized or cast-iron pipe, and a main drain that has seen decades of tree roots — slow drains and pinhole leaks are common calls. Meanwhile, newer homes are usually PEX and PVC, so calls tend to be fixtures, water heaters reaching the end of their life, and sump or ejector pumps in finished basements.
Seasonal notes for Olathe
Hard freezes in the metro are when pipes in exterior walls, crawlspaces, and hose bibs split — and the leak often shows up only when things thaw.
A leak at the meter or in the street is usually a job for the City of Olathe; leaks on the house side of the meter — supply lines, the main shutoff, water heaters, and fixtures — are what a TOD partner fixes in Olathe, KS.

Plumbing in Olathe: common questions
- Does plumbing in Olathe need a permit?
- It depends on the job. Like-for-like repairs often don't; replacements and new work (water heaters, new circuits, furnace or A/C swaps, reroofs) usually do. Permits in Olathe are issued by the City of Olathe, and the partner doing the work pulls any permit the job needs. In Johnson County, permitted plumbing also requires a county contractor license — class DP (plumbing) — and TOD checks partners who serve Johnson County against the county's public license roster.
- Which parts of Olathe do you cover for plumbing?
- All of Olathe, KS, including Downtown Olathe, the Cedar Creek area and neighborhoods along K-7. Partners come in via I-35, K-7, and K-10; when you book we confirm the street address and ZIP before anyone is assigned.
- A pipe burst in my Olathe home. What should I do first?
- Shut off the main water valve (often in the basement near the front wall, or at the meter), turn off the water heater if it's draining, and then book or call. If water is near outlets or the panel, stay out of the area.
- Can you replace a water heater in Olathe?
- Yes — book plumbing and describe the tank (gas or electric, gallons if you know them). The estimate covers typical labor and materials; the plumber confirms what your install needs on site.
- Do you cover all of Olathe, KS?
- Yes — Olathe is inside our Kansas City metro service area. When you book, we check the street address and ZIP; if it's in the metro, dispatch assigns an approved partner who serves Johnson County.
- How is plumbing priced in Olathe?
- Booking is free. You'll see an estimate before you confirm, based on what you describe. After the work, the contractor invoices time and materials at their shop rate plus the Trades on Demand platform fee, and you pay Trades on Demand — not the contractor — online.
- What counts as an emergency for plumbing?
- Something actively getting worse or leaving the home unsafe — for example: burst pipe, sewage backup and no water. Book it as an emergency or call (913) 286-6974. If anyone is in danger, call 911 first.
