Water Heater Services for Swannanoa Homes
Cold shower this morning, or a puddle under the tank? O’Sheas Plumbing is a hot water system supplier in Swannanoa, and our job is getting your hot water back. We install, replace, repair and maintain tank and tankless water heaters that run on gas, propane or electricity. Ian O’Shea owns the company, and he’s on site for every job. He installs all brands, so the heater gets picked to fit your house and the way you use hot water. We take calls 24/7, and if you can’t tell yet whether it’s a part or the whole tank, that’s fine.
Repair or Replace a Tank Water Heater?
On a tank water heater, Ian first sorts out whether a part failed or the tank itself did. A worn part can be swapped, and the heater keeps going. A tank that’s leaking through its own steel can’t be patched, so no new part will save it. Rust streaks or a wet floor right under the tank, with dry fittings above it, usually mean the tank itself has failed. These usually point to a part, not the tank:
Ian replaces a worn thermocouple, heating element, dip tube or gas control valve as water heater repair. When the tank body itself is seeping, it’s time for water heater replacement, and hauling the old tank away is part of that job.
Gas, Propane and Electric Water Heaters
The fuel your house runs on shapes most of the job, whether you keep a tank or move to a tankless water heater. A gas water heater needs a gas line sized for it and venting that carries exhaust outside. A propane water heater works the same way, running off your propane tank. An electric water heater needs no vent, but it does need a circuit sized for its heating elements. If you’re thinking about switching fuel, plan it while the old heater still works, because a new gas line or circuit takes time. Tank size comes next, and many homes land on one of the 40- and 50-gallon tanks, matched to how many people shower in the morning.
Anode Rods, Relief Valves and Yearly Checks
A water heater maintenance visit checks the anode rod and the T&P relief valve, and it clears the sediment off the bottom of the tank. Where a house has an expansion tank, its pressure gets checked too. Once you can see the anode rod’s steel core wire, the rod is spent and the tank’s steel is next. Tankless units need upkeep of their own, mostly a descale of the heat exchanger, and the same kind of visit covers them. If you’re wondering how many years your tank has left, How Long Do Water Heaters Last walks through the signs.

Water Heaters After the Helene Water Outage
Swannanoa’s public water comes from the City of Asheville, and most of that supply starts at the North Fork Reservoir. When Helene washed out the transmission main, Swannanoa’s taps stayed dry until mid-October 2024. Every water heater on that system sat idle through the outage, then refilled with whatever the returning water carried. If yours rumbles now, or nobody’s looked at it since, a maintenance visit is the place to start.
On Swannanoa’s mill-era streets, like Whitson Ave, Morgan Ave and Dennis St, an older house can have its heater tucked in a tight closet. The spot and the way out get measured before a new tank is picked, since a taller one may not fit where the old one stood.
Commercial Water Heaters in Swannanoa
A business can’t go long without hot water, since the kitchen sink and the restroom taps all depend on it. Ian holds a Plumbing Class I Contractor license, North Carolina’s unrestricted plumbing class, so he can take on commercial buildings as well as houses. In the trade since 2003, Ian worked on commercial plumbing in hospital surgical rooms before he started O’Sheas Plumbing. We handle commercial water heaters with the same owner on site, scheduled around your open hours where the job allows.
When a Water Heater Leaks Right Now
If the tank is leaking now, shut off its water and its fuel. Close the cold water valve on the pipe feeding the top of the heater. Then turn the gas control to off on a gas or propane unit, or switch off the breaker on an electric one. Keep clear of the T&P discharge pipe, because water from it can scald. Once it’s off, call (828) 348-5820, and Sarah, who answers day or night, will take down what the tank is doing. Ian also works as a full-service plumber across the Swannanoa Valley, so a leaking supply line nearby is his job too.

Did you know?
A Norwegian engineer working for George Westinghouse in Pittsburgh gave us the tank water heater. In 1889, Edwin Ruud designed an automatic gas storage heater with a temperature-controlled valve, and the idea’s still in basements today.
FAQs About Hot Water System Supplier in Swannanoa
Most of these start with something you can see or hear at the tank, like a rumble or a dripping relief valve. Don’t see what you’re looking for? Ask a question here.
Tank size and fuel set the baseline, along with whether it’s a like-for-like swap and how easy the unit is to reach. Changing fuel, location, capacity or venting turns a simple swap into a bigger job. Code updates the old install lacks, such as an expansion tank or a drain pan, add to it.
Sometimes not. North Carolina exempts some water heater replacements in one- and two-family dwellings from a permit. The swap must be done by a licensed plumber who checks the finished work and sees that the gas piping was leak tested. The new heater also can’t draw more energy than the old one or change fuel, location, capacity or venting. Swannanoa is unincorporated, so Buncombe County handles permits for anything outside those limits.
That depends on how your household uses hot water and what the house can support. A tank stores 40 or 50 gallons and is simpler to swap. Tankless heats on demand without running out, but flow limits how many fixtures run at once. Tankless often needs a larger gas line, new venting and a condensate drain, and electric models need a heavy electrical supply. O’Sheas Plumbing looks at your gas line, venting and fixture demand before you choose.
Popping or rumbling usually means sediment has settled on the bottom of the tank, and water trapped under it boils as the burner fires. After Helene, the City of Asheville, Swannanoa’s public water supplier, told customers to flush lines as service returned. Flushing the tank helps, but a badly scaled tank may be near the end.
Hot water that runs out early usually comes from sediment filling the tank, a failed heating element or a broken dip tube. A broken dip tube lets cold water mix at the top, so showers turn lukewarm. Sometimes the tank is simply too small for the household. O’Sheas Plumbing checks the element, dip tube and sediment level before recommending a repair or a larger tank.
It’s a safety valve that opens if tank temperature or pressure climbs too high. A valve that drips now and then can point to high pressure or a missing expansion tank. A valve that’s stuck or corroded shut needs replacing right away. Never cap or plug the discharge pipe; call O’Sheas Plumbing instead.
An anode rod is a metal rod inside the tank that corrodes so the steel tank doesn’t. Once it’s mostly eaten away, the tank itself starts to rust. Checking it every few years during water heater maintenance helps a tank last longer. Ian checks the anode on maintenance visits around Swannanoa and replaces it when there’s little left.
A worn thermocouple is the usual cause on a gas or propane water heater. That part tells the gas control valve the flame is there. Dirt in the pilot tube or a failing gas control valve can cause the same thing, and poor venting can starve the flame. O’Sheas Plumbing repairs gas, propane and electric water heaters across Swannanoa and Black Mountain.
Not until a plumber checks it. Floodwater can ruin gas controls, burners, insulation and electrical parts, so don’t relight or power it up first. Gas controls that have been underwater are usually replaced, and in many cases the whole heater is. Homes on low ground along the Swannanoa River took floodwater in Helene, so this check matters there. O’Sheas Plumbing can tell you what’s salvageable.
Size it by the first hour rating, which is how much hot water the heater delivers in a busy hour. For many households a 40 or 50 gallon tank covers it, depending on bathrooms, people and big tubs or appliances. Gas tanks recover faster than electric ones of the same size. Ian sizes the unit to your peak use rather than copying the old tank’s label.
