Common Toilet Problems We Fix in San Jose

Running Toilet (Water Won’t Stop)

A toilet that keeps running or refills every few minutes wastes up to 200 gallons of water per day. Cause is almost always a worn flapper (rubber seal at tank bottom), a fill valve that won’t shut off, or a chain that’s too short. Repair takes 30 to 60 minutes.

Clogged Toilet

Standard plunging clears about 80% of clogs. When plunging fails, the blockage is past the trap — often a foreign object, hygiene product, or excess paper. We use a closet auger to reach past the trap safely without scratching porcelain. If needed, we remove the toilet for direct access.

Leaking Around the Base

Water pooling at the toilet base indicates wax ring failure — the seal between the toilet and floor drain. Ignored base leaks cause subfloor damage within months. Wax ring replacement takes 1 to 2 hours and costs $175 to $350 in San Jose.

Weak Flush

Weak flushes come from mineral buildup blocking the rim holes under the bowl edge, low tank water level, a warped flapper closing too fast, or a partial drain line clog. We diagnose and address the actual cause — not just clean the bowl.

Toilet Won’t Fill or Fills Too Slowly

Slow-filling tanks are usually caused by mineral buildup restricting the fill valve, a partially closed shutoff valve, or a bad fill valve. Replacement fill valves cost $20 to $60; professional installation is $125 to $200

Constant Small Drips into the Bowl

If you see water trickling into the bowl between flushes, the flapper isn’t sealing properly. Add food coloring to the tank — if it appears in the bowl within 15 minutes without flushing, you’ve confirmed a flapper leak.

Complete Toilet Services in San Jose

Toilet Repair

Diagnosis and repair of running toilets, leaks, weak flushes, and any other functional issue. Most repairs complete in under 90 minutes with same-day service.

Toilet Installation

Installation of new toilets in existing bathrooms — either replacing an old unit or first-time installation. Includes wax ring, closet bolts, water supply connection, and full testing.

Toilet Replacement

When only the bowl is cracked or damaged (tank still works fine), we replace just the bowl. Cost-effective option for two-piece toilets where the tank is fine.

Fill Valve & Flapper Replacement

Replacement of tank internal components — fill valve, flapper, flush handle, and refill tube. Fixes running toilets and weak flushes. Fast, affordable, and prevents wasted water.

Toilet Flange Repair

Repair of the toilet flange (the ring that connects the toilet to the drain). Cracked or corroded flanges cause wobbling toilets and leaks. Includes flange replacement and floor inspection.

Emergency Toilet Service

24/7 emergency response for overflowing toilets, severe leaks, and complete toilet failures — especially important for single-bathroom homes.

Should You Repair or Replace Your Toilet?

Repair Signs

Repair is the right call when: the toilet is under 15 years old, it’s a modern low-flow model, the porcelain has no cracks, only internal parts (flapper, fill valve, wax ring) are failing, and repair cost is under $200.

Replace Signs

Replacement makes sense when: the toilet is pre-1994 (uses 3.5+ gallons per flush — massive water waste), the porcelain has visible cracks, wobbling can’t be fixed by tightening bolts, weak flushes persist after cleaning rim jets, multiple repairs in the past 2 years, or the flange is deeply corroded.

FAQ

Toilet repair in San Jose typically costs between $125 and $400 depending on the issue. Fill valve or flapper replacement costs $125 to $200. Wax ring replacement (for base leaks) costs $175 to $350. Toilet unclogging costs $150 to $300. Full toilet installation with a new mid-range unit costs $350 to $800. Premium toilet replacement (Kohler, TOTO) ranges from $600 to $1,500.

A constantly running toilet is almost always caused by one of three problems: a worn flapper that doesn’t seal properly (most common — cheap and easy to fix), a fill valve that doesn’t shut off when the tank is full, or a chain that’s too short and keeps the flapper open. A running toilet wastes 200 gallons per day — nearly 6,000 gallons per month — significantly increasing your water bill.

A toilet leaking at the base usually means the wax ring seal between the toilet and floor drain has failed. Signs include water pooling around the base, floor discoloration, and sewer smell. Wax ring replacement typically costs $175 to $350 in San Jose and takes 1 to 2 hours. If left unrepaired, base leaks cause subfloor damage requiring more expensive repair.

When a plunger doesn’t clear a toilet clog, the blockage is usually past the trap — often a foreign object like a toy, feminine product, or excess paper. A closet auger (toilet snake) can reach past the trap without scratching the porcelain. If a closet auger doesn’t work, the toilet may need to be removed to access the blockage directly. Call for professional service if two attempts fail.

A residential toilet typically lasts 20 to 50 years — often outlasting the house’s other plumbing. However, internal parts like fill valves, flappers, and flush handles need replacement every 5 to 10 years. Signs it’s time to replace the entire toilet include cracks in the porcelain, chronic clogs from an outdated 5+ gallon flush, wobbling that can’t be shimmed, or wanting a modern water-efficient model.

Standard toilet replacement in San Jose takes 1 to 2 hours from start to finish. This includes removing the old toilet, replacing the wax ring, installing the new unit, connecting the water supply, and testing for leaks. More complex replacements (relocating the toilet, floor repair, or upgrading rough-in) can take 3 to 5 hours.

Yes. We provide 24/7 emergency toilet service for overflowing toilets, sewer backups, and severe leaks. If your toilet is overflowing, turn off the water supply valve located behind the toilet (turn clockwise), then call (669) 332-9191. Emergency dispatch fees apply for after-hours service.
