Quick answer
Summit Flow Plumbing repairs and replaces toilets throughout Louisville. Most repairs, running toilets, weak flushes, fill problems, are done in a single visit for a flat rate; full replacement with a water-saving WaterSense model typically takes about an hour. A constantly running toilet wastes 200+ gallons a day, so call sooner: (502) 555-0148.
The problems we fix every week
The toilet that never stops running
That quiet hiss is your water bill leaking into the sewer. A worn flapper, an over-filled tank, or a tired fill valve keeps water flowing from tank to bowl around the clock. It’s the cheapest repair on this page and one of the most wasteful problems to ignore.
The phantom flush
A toilet that refills by itself every so often is a slow flapper leak, the tank drains until the fill valve wakes up. Same fix as above, same “why was our bill high?” answer.
Water at the base
A failed wax ring lets each flush seep under the toilet into the flooring. If the toilet also rocks, the flange or its bolts may be the root cause, resetting the toilet without fixing the flange just schedules the next leak.
The chronic clogger
If one toilet needs the plunger weekly, something structural is wrong: a low-flow first-generation model with a weak siphon, scale-blocked jets, an object lodged in the trap (kids’ toys are a classic), or a partial blockage in the branch line. We diagnose which, because plunging the same toilet forever is not a plan.
Cracks, wobbles, and endless repairs
Hairline tank cracks weep invisibly; a rocking bowl chews through wax rings; a 30-year-old toilet eats parts. Past a point, replacement is the honest recommendation.
When replacement beats repair
- Pre-1994 unit: using 3.5–7 gallons per flush versus 1.28 for a modern WaterSense model.
- Any crack in porcelain: cracks only grow, and a tank failure is a flood.
- Repeat repairs: two service calls in a year on an old toilet usually out-costs a new one.
- Constant clogging on a first-gen low-flow (mid-1990s models), modern trapway engineering flushes better with less water.
A replacement visit includes the new toilet, new wax ring and bolts, new supply line, leveling and securing, a leak test, and haul-away of the old unit.
| Toilet era | Gallons per flush | Annual use, family of four* |
|---|---|---|
| Pre-1980s | 5–7 gpf | ~36,000–51,000 gal |
| 1980–1994 | 3.5 gpf | ~25,500 gal |
| Federal standard since 1994 | 1.6 gpf | ~11,700 gal |
| EPA WaterSense | ≤1.28 gpf | ~9,300 gal |

What a running toilet actually costs
The EPA estimates household leaks nationally waste about 10,000 gallons per home per year, and running toilets are a lead contributor, a bad flapper alone can pass 200+ gallons a day. On a Louisville Water Company bill, that’s a leak you can see in the numbers within one billing cycle. The food-coloring test takes 15 minutes and costs nothing; the repair is one flat-rate visit.

FAQ
Toilet questions, answered
Straight answers to the questions our dispatchers hear most. Don't see yours? Call (502) 555-0148 and ask a person.
Why does my toilet run constantly?
Ninety percent of running toilets are one of three cheap parts: a worn flapper that no longer seals (the most common), a fill valve that never shuts off, or a float set too high so water spills down the overflow tube. The food-coloring test finds a bad flapper: drops in the tank, wait 15 minutes without flushing, color in the bowl means the flapper leaks. A running toilet can waste over 200 gallons a day, so it pays for its own repair fast.
How much does toilet repair or replacement cost?
U.S. homeowners typically see $100–$300 for common repairs (flapper, fill valve, flush handle, supply line) and $400–$800+ installed for a full replacement including the new toilet, wax ring, and haul-away, with wall-hung or smart models running higher. Summit Flow quotes flat-rate before work starts, and will tell you when a repair is throwing money at a toilet worth replacing.
Is water around the base of the toilet serious?
Treat it seriously. Occasionally it is condensation, but persistent water at the base usually means the wax ring seal has failed: and every flush is then seeping under the flooring, rotting subfloor and, in bathrooms over living space, staining the ceiling below. The fix (pull, reseal, reset) is quick and cheap compared to subfloor repair. Do not keep using a toilet that rocks; rocking is how wax rings fail.
Why is my flush weak?
Common causes in order: mineral deposits clogging the rim jets and siphon jet (very fixable), a partially stuck flapper closing early, low tank water level, or a partial drain blockage downstream. In older Louisville homes, decades of moderately hard water can scale the rim jets shut, the toilet is fine; its water passages need cleaning. If plunging is becoming routine, the problem is usually the drain, not the toilet: see our drain cleaning page.
Should I replace my old toilet even if it works?
If it predates 1994, probably yes. Pre-1994 toilets use 3.5–7 gallons per flush; the federal standard since then is 1.6, and EPA WaterSense models use 1.28 or less while flushing better than older designs. For a family home, swapping a 5-gallon relic for a WaterSense model saves thousands of gallons per year, the replacement gradually pays for itself on the water bill.
What should never be flushed?
Only the three P’s: pee, poop, and (toilet) paper. Wipes, including “flushable” ones, paper towels, cotton products, dental floss, hygiene products, and cat litter all either snag in the trap or weave into rope further down the line. Most “toilet keeps clogging” calls end at one of these.
