Bathroom plumbing repairs for toilets, faucets and showers

Bathrooms have more plumbing packed into a small space than almost any other room. Toilets, sinks, tubs and showers each have supply connections, valves and drains, and many of those connections sit behind walls or under floors where a small leak can go unnoticed. A toilet that runs constantly can waste a considerable amount of water, and a slow leak under a vanity or around a toilet base can damage subflooring and ceilings below.

Most bathroom plumbing repairs are straightforward when handled early. Replacing a worn flapper or fill valve stops a running toilet. A new cartridge or washer fixes a dripping faucet. Resetting a toilet on a new wax ring stops leaks at the base. The key is identifying the correct part for your fixture, since faucet and valve cartridges vary widely by manufacturer.

We diagnose the problem, explain the repair and quote a flat price. Common parts are carried on the truck, and brand-specific cartridges are sourced when needed.

Inside a toilet tank, the fill valve refills the tank after each flush and shuts off at the correct water level, while the flapper seals the flush valve opening. When the flapper warps or the chain tangles, water leaks into the bowl and the fill valve runs to replace it. A simple dye test, adding a few drops of food coloring to the tank and waiting without flushing, shows whether water is leaking into the bowl. At the base, a wax ring seals the toilet to the drain flange. If the toilet rocks or the flange is damaged, the seal fails and must be replaced along with any flange repair.

Faucets use cartridges, compression stems, ball assemblies or ceramic discs depending on the design. Replacing a worn cartridge with the correct manufacturer part usually stops drips without replacing the faucet. Shower valves in most modern homes use pressure-balancing or thermostatic cartridges to prevent sudden temperature changes. Mineral buildup or worn seals can make these valves stick or allow temperature swings. Servicing or replacing the cartridge restores safe, stable temperatures.

Bathroom plumbing problems often begin small. A running toilet may be caused by a worn flapper, a misadjusted fill valve or a chain that catches. A toilet that rocks may have a failing wax ring or loose flange bolts, which can allow leaks under the floor.

Faucet drips usually come from worn cartridges, washers or seals. Shower valves can develop drips, temperature fluctuations or difficulty adjusting temperature when cartridges wear or mineral deposits build up. Pressure-balancing valves may need cleaning or replacement to maintain stable temperatures.

Slow drains in sinks and tubs are commonly caused by hair and soap buildup. Drain stoppers and overflow assemblies can collect debris. Leaks under sinks may come from supply connections, drain slip joints or cracked fittings.

Hidden leaks require careful investigation. Stains on ceilings below bathrooms, loose tiles or soft floors can indicate leaks from drains, supply lines or shower pans. Identifying the source prevents damage and mold growth.
