Leaking Water Heater and Relief Valve Repair in West Palm Beach
Relief valve $50 to $300; tank replacement from $600 to $2,200
Water around a water heater comes from one of five places. Three are repairs, one dries up on its own, and one means a new tank.
Where the water comes from
- The cold or hot connections on top. A loose or corroded connector or nipple. A repair.
- The relief valve or its discharge pipe. The valve is letting off heat or pressure, or it is worn. A new valve, and a look at why it opened.
- The drain valve near the bottom. Plastic drain valves crack and leak, and sediment keeps them from closing. A repair.
- Condensation on a gas tank. A new tank filled with cold water can drip on the burner for a few minutes. It stops on its own.
- The tank itself. Water from under the jacket or the bottom of the tank. Rust has eaten through. Replace.
The relief valve
The temperature and pressure relief valve opens when the water passes about 210 degrees or about 150 psi. A valve that drips now and then is usually reacting to thermal expansion on a closed system or to high street pressure. A valve that runs steadily means the thermostat may be stuck and the water is overheating. Never plug or cap the discharge pipe. That valve is what keeps a tank from failing violently.
Storm season
Atlantic hurricane season runs June 1 to November 30. Before a storm, shut the heater down the way the manufacturer's manual says. A water heater that sat in floodwater stays off until a plumber has checked it, and an electrician too on an electric unit, and nobody switches power on while standing in water.
Condos and finished floors
Florida's Condominium Act says the association's property insurance must exclude water heaters inside a unit and makes them the unit owner's responsibility, so the repair or replacement is yours to book. Your declaration and the building manager set any rules on access and timing. A water heater in an interior closet, over finished flooring or in an attic should sit in a pan with a drain, and a leak sensor with an automatic shutoff valve costs far less than one ruined ceiling.
What it costs
A relief valve is $50 to $300. Fittings, connectors and drain valves are priced on the spot. If the tank is the leak, replacement runs $600 to $2,200 for electric and $800 to $2,500 for gas, and most swaps are done the same or next day.
Water on the floor is the call that cannot wait. Shut the cold supply, kill the power or gas, and call (561) 264-5624.
