A toilet that runs constantly wastes 26โ200 gallons per day โ that's $15โ$100 extra monthly for a problem that typically costs under $200 to fix. A rocking toilet that's dismissed as a loose bolt without checking the wax ring risks sewer gas seeping into the floor cavity with every flush. Masters Plumbing Service's toilet techs in Oak Brook carry fill valves, flappers, wax rings, flush valves, and toilet bolt sets to resolve every common toilet problem in a single visit.

Toilet repairs look simple until the wrong cartridge is installed in a fill valve, or a wax ring is reset over a damaged flange that can't hold a seal. Our techs identify the actual failed component โ not the most obvious guess.
Phantom flushing (spontaneous refill between uses) almost always indicates a flapper that no longer seals. But sometimes it's a hairline crack in the overflow tube keeping the water level from holding. We check both.
For toilets where the flush valve seat is chipped or the porcelain tank has cracked, we also carry compact replacement toilet units in standard rough-in dimensions.
A common mistake is resetting a toilet over a partial old wax ring or onto a damaged flange. We clean and inspect the flange, note any damage, and install the correct ring profile before reset. The toilet should not rock at all when we leave.
We quote toilet work at a flat rate before any repair begins. Whether it's a 20-minute fill valve swap or a 90-minute toilet reset with flange repair, you know the price before we start. Our rates for common toilet repairs are transparent โ ask for them when you call.
From a constantly running tank to a toilet that's been loose on the floor for years, here's what our toilet techs address in Oak Brook, IL.
Old-style ballcock fill valves with a float ball and brass arm are still common in older Oak Brook homes. We replace these with modern Fluidmaster-style anti-siphon fill valves that provide more reliable shutoff, quieter fill, and a 5-year warranty against failure.

If the flange is damaged โ cracked porcelain collar, corroded cast iron, or a flange sitting below finished floor height โ we repair or shim the flange before wax ring installation. A wax ring on a damaged flange won't hold long-term.
If the auger retrieves material and the toilet still doesn't clear, the blockage may be further in the drain line. We can extend with a sectional cable machine or CCTV camera to determine if a foreign object is lodged deeper.
For dual-flush toilets and pressure-assist units, internal mechanism repair requires model-specific parts โ we carry kits for major brands.

This repair is commonly misidentified as a wax ring issue when water appears at floor level โ water from a tank bolt leak runs down the outside of the bowl and accumulates at the base, looking identical to a wax ring leak until you trace the water path.
We handle the full process: shut water, pull old toilet including wax ring and flange inspection, set the new unit, connect supply, and verify flush performance and seal before leaving.
We don't replace everything hoping one part was the issue. A short diagnostic step tells us exactly which component failed โ and we fix that one.
Running after every flush? Wobbles when you sit? Won't clear on the first flush? Water on the floor after flushing? Each symptom points to a short list of components. Our dispatcher notes your symptom so the tech arrives with relevant parts loaded.
For a rocking toilet, we assess floor movement, flange bolt tightness, and wax ring seal before recommending the appropriate repair.
If diagnosis reveals a more involved repair than expected (damaged flange, cracked tank), we explain it before proceeding and re-quote accordingly.
Approved repairs execute immediately. After completion, we run five flush cycles to confirm: silent tank refill, no base movement, clear bowl, no water at the base.

Master bath toilet had been running intermittently for months. Masters Plumbing Service's tech diagnosed a deteriorated flapper seat and an aging fill valve that wasn't shutting off reliably. Replaced both in 35 minutes. Completely silent now. The tech also found my water pressure was running at 95 PSI โ well above the 80 PSI recommended โ and adjusted the pressure regulator, which had been stressing the fill valve. That kind of thorough thinking is why I called a plumber rather than replacing parts myself.
My kids flushed something I have no interest in describing, and the toilet wasn't clearing. The tech used a closet auger and retrieved the obstruction without damaging the porcelain. Fast, professional, zero judgment. Exactly what I needed.
Old toilet in a rental unit had a slow running sound the tenant reported as intermittent. Masters Plumbing Service's tech found a crack in the overflow tube inside the tank โ allowing the water level to drop slightly, triggering brief fill cycles every 20โ30 minutes. A problem I'd never have found on my own. New fill valve assembly fixed it.
