A toilet that runs constantly wastes 26โ200 gallons of water per day depending on the severity โ that's $20โ$100 extra on a monthly water bill for a problem that typically requires a $15 part and 30 minutes to fix. A toilet that rocks on the floor is either a loose flange bolt or a deteriorated wax ring โ and if it's the wax ring, every flush risks sewer gas leaking into the structure. Masters Plumbing Service's toilet techs in Woodway, WA carry fill valves, flappers, wax rings, flush valves, toilet bolts, and supply lines to resolve every common toilet problem in a single visit.

A rocking toilet that's dismissed as a loose bolt and tightened without replacing the wax ring will continue letting sewer gas into the bathroom floor cavity. The right diagnosis matters.
Phantom flushing (spontaneous refill with no flush) almost always indicates a flapper that no longer seals โ a 10-minute repair. But sometimes it's a hairline crack in the overflow tube that keeps 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 that needs addressing, and install the correct ring profile before reset. The toilet should not rock at all when we leave.
We don't upsell a toilet replacement when the existing toilet is functional and the problem is a repairable component. Honest diagnosis produces honest recommendations.
Our trucks are stocked for the most common toilet repairs โ most calls complete in a single visit.
A running toilet is almost always caused by one of two things: a flapper that no longer seats fully against the flush valve (allowing water to trickle from tank to bowl), or a fill valve that won't shut off at the target water level. We dye-test to confirm the flapper seal, check fill valve shutoff behavior, and replace whichever component โ or both โ is responsible.
A toilet that rocks on the floor, shows water staining at the base after flushing, or emits sewer gas odor near the floor needs to come up for a wax ring inspection. We pull the toilet, remove the old ring completely, inspect the closet flange for cracks or corrosion, install the correct wax ring profile for the finished floor height, and reset and secure the toilet.
A toilet that won't clear with a plunger has either a tight clog in the trap or a blockage in the drain arm beyond the trap. We use a closet auger โ a specialized toilet snake with a protective rubber boot โ to reach through the trap and break or retrieve the obstruction without scratching the porcelain bowl.
The flush valve is the large central drain at the bottom of the toilet tank. Over time, the flush valve seat โ the surface the flapper seals against โ can develop mineral scale buildup or micro-fractures that prevent the flapper from sealing completely. If a new flapper doesn't resolve a running toilet, the flush valve seat is the next check.
This repair is commonly misidentified as a wax ring issue when the water appears at floor level. Water from a tank bolt leak runs down the outside of the bowl and accumulates at the base โ looking identical to a wax ring leak until you trace the water path.
When a toilet is cracked, has a non-rebuildable internal flush mechanism (common in some older European-style or wall-hung units), or the overall condition warrants replacement, we supply and install a new unit in the correct rough-in dimension for your bathroom. Standard 12-inch rough-in toilets are stocked on our trucks; 10-inch and 14-inch rough-in units can be sourced same-day or next-day.
We don't replace everything and hope one part was the issue. A short diagnostic step tells us exactly which component failed โ and we fix that one.
We ask whether you have a gravity-feed toilet (standard) or a pressure-assist model, which affects which parts we bring.
For a rocking toilet, we assess floor movement, flange bolt tightness, and wax ring seal before recommending the appropriate repair.
If the diagnosis reveals a more involved repair than initially 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 the repair holds โ silent tank refill, no base movement, clear bowl, no water at the base.

Master bath toilet had been running intermittently for months โ I kept jiggling the handle. Masters Plumbing Service's tech diagnosed a deteriorated flapper seat and an aging fill valve that wasn't shutting off reliably. Replaced both in about 35 minutes. The toilet is completely silent now. The tech also found that my water pressure was running at 95 PSI โ well above the 80 PSI max recommended โ and adjusted the pressure regulator, which was stressing the fill valve in the first place. That kind of thorough thinking is why I called a plumber rather than just replacing parts myself.
My kids flushed something that 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.
Older toilet in a rental unit had a slow running sound that the tenant reported as intermittent. Masters Plumbing Service's tech found a crack in the overflow tube inside the tank โ it was 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 completely.
