Toilet Problems We Fix Every Day
We diagnose the real problem, not just the symptom. These are the calls we get most.
The most common call, and the most wasteful. A worn flapper, a fill valve that won't shut off, or a pitted flush-valve seat. Houston's chlorinated water is hard on rubber flappers, and many fail in 3 to 5 years. Usually a fast, inexpensive fix that pays for itself.
Your toilet refills on its own every 20 minutes to a few hours with nobody touching it. Tank water is leaking into the bowl past a deteriorated flapper or warped seat. A dye-tablet test confirms it in ten minutes.
A one-time clog is a plunger job. Repeated clogs point to a trapway obstruction, a weak early-1990s low-flow design, or a developing blockage in the drain or sewer line, common in older Houston neighborhoods.
Water pooling at the base usually means a failed wax ring or a toilet rocking on a damaged flange. Never ignore it: that water comes from the drain side and wicks under tile and subfloor on a slab before you see it.
On two-piece toilets, the tank bolts to the bowl with a sponge gasket and bolt seals. When the rubber ages, water drips every flush and warps cabinets and trim. An inexpensive gasket-and-bolt fix.
Clogged rim jets, a flapper closing too early, low tank level, or a blocked trapway or vent. First-generation 1.6-gallon toilets (1994 to the early 2000s) are notorious for weak flushes no matter what you do.
Hairline tank cracks weep slowly; a cracked bowl can fail suddenly and flood a bathroom. Porcelain can't be reliably patched. A cracked bowl means a new toilet.
A toilet should not move. Rocking wears the wax seal, leaks sewer gas, and stresses the flange bolts. In Houston it's frequently a cracked flange or one that has shifted with the slab.
The Houston Problem: Slab Foundations, Clay Soil, and Broken Flanges
Most Greater Houston homes sit on slab-on-grade foundations poured over expansive clay soil. That clay swells when it rains and shrinks during our droughts, and the slab moves with it. The toilet flange, the ring that anchors your toilet to the drain pipe in the slab, is a fixed point in a moving system. When the slab shifts, flanges crack, tilt, or end up sitting too low or too high relative to the finished floor. The symptoms are a toilet that rocks, a wax seal that keeps failing, or a base leak that comes back after every fix.
We repair flanges properly: repair rings and spanner flanges for cracked plastic, full flange replacement when needed, and flange extenders when new flooring has raised the floor above the flange. When a flange sits badly out of level or the pipe below it has separated, we tell you honestly whether the problem is the flange or the drain line under the slab, and we can camera the line to prove it before anyone talks about breaking concrete.
Cast-Iron Flanges in Older Houston Homes
In the Heights, Meyerland, Bellaire, Oak Forest, and Garden Oaks, your toilet likely sits on a cast-iron flange tied to cast-iron drains. After 50 to 70 years, cast iron rusts from the inside out: bolt slots rust away, the rim flakes apart, and the hub weakens. We repair it with twist-set replacement flanges, repair rings rated for cast iron, or cutting back to sound pipe and transitioning to PVC. We work on cast iron weekly and carry the parts on the truck.
When the Toilet Isn't the Problem: Sewer-Line Ties
Your toilet is the largest fixture on the drain and usually the first to show sewer trouble. Recurring clogs, gurgling, sewage smell, or backups into the tub all point downstream. Before you pay to fix a toilet three times, let us camera the sewer line once. If the line is the issue, we'll show you the footage and quote the repair, no guessing.
What a Running Toilet Costs You
The EPA estimates a running toilet can waste up to 200 gallons per day, roughly 6,000 gallons a month from one fixture. City of Houston customers pay for that water twice, because wastewater charges are billed on top of usage. At Houston's combined rates, a constantly running toilet can add $60 to $100 or more per month, and a bad phantom-flush leak can add $20 to $40 without ever making a sound. If your bill jumped and nothing else changed, put a few drops of food coloring in the tank, wait 15 minutes without flushing, and check the bowl. the repair typically costs less than two months of the waste. If the tank keeps refilling with nobody touching the handle, that is the phantom flush described above, and our guide to a toilet flushing on its own walks through all six causes.
What one running toilet can waste (EPA), and in Houston you pay for it twice: water plus wastewater.
One note on rebates: unlike Austin and San Antonio, the City of Houston does not currently run a citywide toilet rebate program for residential customers. The savings from a WaterSense toilet (1.28 gallons per flush, 20% below the 1.6 GPF standard) come off your bill directly, typically thousands of gallons a year versus a pre-1994 model. Some MUDs outside the city periodically offer incentives; ask us and we'll check what applies to your address.
Repair or Replace? An Honest Framework
We fix toilets when fixing makes sense. Here's the same logic we use on the job.
Repair it when
- It's under 15 years old and the porcelain is sound.
- The problem is internal parts: flapper, fill valve, flush valve, handle, or tank gasket.
- It's a quality fixture (TOTO, Kohler, American Standard, Gerber) with parts readily available.
- The wax ring or bolts failed but the flange is in good shape.
Replace it when
- The bowl is cracked, or the tank is cracked with no replacement available.
- It's a 1980s 3.5-plus GPF toilet or an early-90s first-generation 1.6 GPF with chronically weak flush.
- Repair quotes exceed roughly half the cost of a comparable new toilet installed.
- It clogs constantly despite a clear drain line.
- You're paying Houston water rates on a 3.5 to 7 gallon flush (a WaterSense toilet cuts per-flush use by 60 to 80%).
- You want comfort height, an elongated bowl, or a bidet seat anyway.
A well-made toilet lasts 25 to 50 years, but the internal parts last 4 to 10. Most bad toilets just need parts. Most pre-1994 toilets aren't worth putting parts into.
Toilet Types We Install
Gravity-fed
The standard. Water weight drives the flush. Quiet, simple, cheap to maintain, and in 95% of homes.
Pressure-assist
A sealed inner tank uses line pressure for a stronger flush. Great for frequent clogs or long drain runs; louder, and parts cost more.
Two-piece vs. one-piece
Two-piece is cheaper and easier to carry in, but the tank gasket is a future maintenance item. One-piece costs more, has no tank-to-bowl joint to leak, and is easier to clean.
Comfort height (chair height)
17 to 19 inches to the seat versus about 15 for standard bowls. Meets ADA height guidelines and is easier on knees and backs. Our most-requested upgrade for anyone over 50. Worth knowing that comfort height and ADA compliant are not the same thing, and standard vs ADA compliant toilet explains where the two diverge before you buy.
Elongated vs. round
Elongated bowls extend about 2 inches farther and are more comfortable; round bowls fit tight powder rooms. Measure your rough-in (usually 12 inches) and door clearance before buying.
Dual-flush
Two buttons, a light flush for liquids and a full flush for solids. Real water savings, though some big-box valves use nonstandard parts.
Smart toilets & bidet seats
Heated seats, washing, night lights, auto-flush. A bidet seat needs a GFCI outlet within reach and an elongated bowl; we handle the outlet coordination, seat, and supply tee correctly the first time.

Top Toilet Brands We Repair and Install
We install any toilet you supply, or we'll source one and tell you plainly which models we'd put in our own homes.
TOTO
Drake, Entrada · $250 to $600The Drake is the toilet plumbers buy for their own homes: two-piece, elongated, Tornado Flush, 1.28 GPF option. It clogs rarely and flushes quietly. The Entrada is the efficient entry line. TOTO's failure rate is the lowest we see. Some proprietary flappers and valves, so bring us the model number; we stock common TOTO parts.
Kohler
Highline, Cimarron · $200 to $450The Highline is a workhorse two-piece, most versions in Comfort Height. The Cimarron uses Kohler's AquaPiston canister flush, strong and even, but the canister seal is a known wear item that causes running toilets. The replacement seal is cheap and we carry it. Parts availability is excellent across Houston.
American Standard
Champion 4, Cadet 3 · $150 to $500The Champion 4 is built around a 4-inch piston flush tower and an extra-wide 2-3/8-inch trapway, one of the most clog-resistant toilets made, with a 10-year warranty. Early flush-tower seals had a leak issue; we retrofit the updated part. The Cadet 3 is the sensible budget pick with standard, easy-to-service parts.
Gerber
Viper, Avalanche · $200 to $450A pro-channel brand sold through supply houses. It flushes hard for the money and uses widely available standard parts. A frequent choice when we supply the toilet on a replacement: dependable, unfussy, and easy to keep running.
Glacier Bay
Budget · $100 to $250Home Depot's house brand and often the cheapest in the aisle. Fine for light-use bathrooms and rentals. Trade-offs: part quality varies by run, and some models (especially dual-flush) use proprietary valves that take longer to source. We repair them regularly; just expect a parts hunt on some models.
Delta
Budget · $150 to $300Better known for faucets, Delta sells value-priced toilets through Home Depot with installer-friendly touches like pre-installed tank hardware. A solid budget option with conventional, easy-to-replace internal parts.
Frequently Asked Questions
How do I fix a running toilet?
Open the tank and check the flapper first. If it’s warped, stiff, or slimy, it’s leaking water into the bowl and needs replacement. If the flapper is fine but water keeps rising into the overflow tube, the fill valve needs adjustment or replacement. Both are quick fixes for a plumber, and at Houston water rates a running toilet wastes far more than the repair costs within a month or two.
How do I unclog a toilet?
Use a flange plunger (the kind with the fold-out cup), seat it over the drain, and push and pull firmly 15 to 20 times while keeping the seal. Most clogs clear this way. If plunging fails, a toilet auger reaches obstructions in the trapway. Skip chemical drain cleaners; they rarely clear toilet clogs and can crack porcelain with heat. Repeated clogging means a trapway obstruction or drain-line problem worth a professional look.
Why does my toilet keep running even after I replaced the flapper?
Either the new flapper doesn’t match the flush valve (flappers aren’t universal; 2-inch and 3-inch valves take different parts, and some brands need specific flappers), the chain is too tight, or the flush valve seat itself is pitted or scaled so no flapper can seal against it. A worn fill valve that won’t shut off produces the same symptom. This is one of our most common service calls, and it’s usually solved in one visit.
Why won't my toilet flush?
If the handle does nothing, the lift chain has detached or broken. If it flushes weakly, the tank water level is low, the flapper closes too soon, or the rim jets are scaled over. If the bowl fills but doesn’t evacuate, the trapway or drain is partially blocked. Each has a different fix, which is why we diagnose before we quote.
How much does toilet installation cost in Houston?
Labor to install a toilet you’ve purchased typically runs $200 to $450 in Greater Houston. With us supplying a quality two-piece toilet, expect $450 to $900 installed, and $550 to $1,200 for one-piece or comfort-height models. Add $200 to $650 if the flange needs repair, common on Houston slabs. We quote the exact price free before any work starts.
How long does a toilet last?
The porcelain itself lasts 25 to 50 years. The working parts don’t: flappers last 3 to 5 years in Houston water, fill valves 5 to 10, wax rings 20 to 30 (less if the toilet rocks). Plan on servicing the internals two or three times over the toilet’s life, and consider replacing any toilet made before 1994, which uses 2 to 5 times the water per flush of a modern one.
Is it worth repairing a toilet, or should I just replace it?
Repair it if it’s under 15 years old, the porcelain is intact, and the problem is internal parts; that’s a modest fix on a fixture with decades left. Replace it if the bowl is cracked, repairs approach half the cost of a new installed toilet, or it’s an old high-consumption model. We’ll give you both numbers and our honest recommendation.
Why does my toilet leak at the base?
The wax seal between the toilet and the flange has failed, or the toilet is rocking and breaking the seal each time it moves. On Houston slabs, repeat base leaks usually mean the flange itself is cracked or out of level from foundation movement; replacing the wax ring alone fixes it for a few months, then it’s back. Don’t keep using a base-leaking toilet, because that water is coming from the sewer side.
Why does my toilet flush on its own at night?
That’s phantom flushing: the flapper is leaking tank water into the bowl until the level drops enough for the fill valve to refill it. It’s silent waste all day long, not just at night; you simply hear it when the house is quiet. A flapper or flush-valve seal replacement ends it.
What is a comfort-height toilet and should I get one?
Comfort height (also called chair height or right height) puts the seat at 17 to 19 inches instead of the standard 15, matching ADA guidelines. It’s noticeably easier to sit and stand, especially for taller people, older adults, or anyone with knee or hip issues. It’s a same-price option on most major lines now, and it’s what we recommend on most replacements unless small children are the primary users.
