“It’s Been Running for Weeks” — We Hear It Every Day
The running toilet is the most ignored plumbing problem in California — and one of the most expensive. A toilet with a bad flapper or fill valve can waste 200+ gallons a day. That’s 6,000 gallons a month, silently inflating your water bill while you get used to the sound.
Callers describe it in familiar ways: “It runs every few minutes,” “I have to jiggle the handle,” “it refills on its own,” “there’s water trickling into the bowl.” These are all symptoms of the same handful of causes, and they’re all cheap to fix — if you know what you’re looking at:
- Worn flapper — the rubber seal warps or degrades (California’s chlorinated water accelerates this). Water leaks from tank to bowl, fill valve kicks on to compensate. The #1 cause of running toilets.
- Bad fill valve — won’t shut off, fills too high, or hisses constantly. Modern fill valves are inexpensive and far more reliable than 20-year-old ballcocks.
- misadjusted float — water level too high sends water down the overflow tube nonstop.
- Cracked overflow tube or flush valve seat — less common, requires valve replacement.
Most running-toilet repairs take 30–45 minutes and cost far less than one month of the wasted water.
Weak Flush? It Might Not Be a Clog.
“It flushes, but… weakly. I have to flush twice.” Before you assume it’s clogged, consider what actually powers a flush: a full, fast dump of tank water through clean rim jets and a clear trapway. When any part of that chain degrades, flushing suffers:
- Clogged rim jets — mineral deposits (very common with California hard water) narrow the holes under the rim that wash the bowl. The fix is cleaning or replacing — and it’s dramatic when done.
- Low tank water level — less water, weaker flush. Often just a float adjustment.
- Partial trapway blockage — not a full clog, just enough restriction to kill siphon action. An auger (closet auger, not a chemical) clears it properly.
- Worn-out 90s-era low-flow — the first generation of 1.6 GPF toilets (1994–2005ish) were notoriously bad flushers. Modern designs flush better on less water. Sometimes the honest answer is a new toilet.
Leaking at the Base? Don’t Ignore It.
Water around the base of the toilet is never “just condensation” for long. It means the wax ring seal has failed, the flange is damaged, or the toilet is rocking and breaking the seal with every use. This is sewage water seeping into your subfloor. Every week you wait, the subfloor damage spreads — and a $400 wax ring job becomes a $2,000 subfloor repair.
We pull the toilet, inspect the flange (repairing or replacing it if cracked — very common in older California homes with cast-iron flanges), install a new wax ring or silicone seal, reset the toilet dead level, and verify with a dye test. Done right, it lasts decades.
Repair or Replace? Our Honest Guide
- Repair it: running/filling issues, weak flush from mineral buildup, handle problems, loose seat, minor leaks at supply line — all cheap fixes on an otherwise good toilet.
- Replace it: cracked tank or bowl (even hairline — they fail catastrophically), recurring clogs from a poorly designed trapway, a 1990s water-guzzler you want to upgrade, or repair costs approaching half the price of new.
- The 50% rule: if the repair costs more than half of a new installed toilet, replace it. We’ll tell you which side you’re on before we start.
New Toilet Installation — Done Right
A proper toilet installation is more than setting a bowl on a wax ring:
- Flange inspection and repair. We check the closet flange height and condition. Too low, cracked, or corroded flanges get repaired or replaced — this is the step skipped by cheap installs, and the reason they leak within a year.
- Quality seal. Premium wax ring (or silicone alternative where appropriate), set once, set right.
- New supply line and angle stop. Included standard. The old braided line and crusty shutoff get replaced while we’re there.
- Level and secure. Shimmed dead-level, bolted to spec — no rocking, ever.
- Tested. Multiple flush tests, dye test for base leaks, fill valve adjusted to the correct water line.
- Haul-away. The old toilet leaves with us. Porcelain recycling where available.
Which Toilet Should You Buy?
As plumbers, we install hundreds of toilets a year. Our honest take: Toto makes the best-flushing toilets in the business (their Drake and Entrada lines are workhorses). Kohler and American Standard make solid mid-range options. For most California homes, a comfort-height (17–19″), elongated-bowl, 1.28 GPF WaterSense model is the sweet spot — qualifies for most water district rebates, flushes well, and fits standard 12″ rough-ins.
Skip the $89 special. The trapway glazing and flush valve quality at that price point will have you calling us for clogs. A $250–$400 toilet installed right will outlast two cheap ones.
California rebate note: many water districts (MWD, LADWP, and others) offer rebates for WaterSense toilets — sometimes $100+. We install qualifying models and provide the documentation you need.
Toilet Costs — Honest Numbers
Running toilet repair: $150–$300 (flapper/fill valve). Wax ring replacement: $350–$600 (more if the flange needs repair). Clog clearing with closet auger: $150–$300. New toilet installed: $350–$700 labor plus the fixture. Flange repair/replacement: $400–$900 depending on what’s underneath.
The DIY Reality Check
Replacing a flapper or fill valve? Genuinely DIY-friendly — ten minutes with a YouTube video. But know when to stop: pulling a toilet to replace a wax ring is heavier, messier, and more technical than it looks (a cracked flange or a toilet set unleveled will leak sewage silently for months). And chemical drain cleaners in toilets are a hard no — they don’t clear the trapway, they damage the wax ring, and they create a chemical hazard for whoever augers it next (which might be us, wearing gloves and respirators). If the plunger and the easy fixes don’t solve it, call before it becomes a subfloor job.
Toilet FAQs
Why does my toilet keep running?
Almost always a worn flapper or faulty fill valve. A running toilet wastes 200+ gallons a day — the repair ($150–$300) pays for itself in one water bill cycle.
How much does toilet installation cost?
$350–$700 for labor including wax ring, supply line, angle stop replacement, and haul-away. The fixture is separate — budget $150–$600 depending on the model.
Water is leaking around the base — how urgent is this?
Very. It’s the wax ring seal failing, and sewage water is reaching your subfloor. Every week of delay risks turning a $400 job into a $2,000 subfloor repair.
Should I repair my old toilet or replace it?
Use the 50% rule: if repair costs more than half of new installed, replace. Cracked tanks/bowls, chronic clogs from bad trapway design, and 1990s-era poor flushers are all replace signals.
What toilet do plumbers recommend?
Toto Drake/Entrada for best flushing, Kohler or American Standard for solid mid-range. Comfort height, elongated bowl, 1.28 GPF WaterSense — and check your water district for rebates.
Can I use chemical drain cleaner in my toilet?
No. It doesn’t clear toilet trapways effectively, damages the wax ring, and creates a chemical hazard for anyone who services it afterward. Use a plunger or closet auger — or call us.
My toilet rocks slightly — is that a problem?
Yes. Rocking breaks the wax seal over time, leading to slow sewage leaks into the subfloor. It needs to be pulled, shimmed level, and resealed. Don’t just caulk around it — that traps the leak inside.
