Contrary to the thought of many homeowners, a leaking hot water heater does not always signify the need to replace the tank. Though the leaks may appear to stem from the tank, they may originate from another source. Rather than replacing the entire machine, a 24 hour plumber can troubleshoot the source of the leak and decide on the type of repair needed. This article highlights the likely sources of leaks in a hot water heater.
You have probably noticed puddles of water at the foot or down the sides of your water heater tank. Typically, the leaks can be attributed to a loose pipe connection. Water leaking from a fitting is a telltale sign of an ill-fitting joint. In terms of repair, the plumber first turns off the cold water supply to the tank and inspects the joints to see any signs of leaking. Any loose fittings are tightened or repaired with the threads being coated with the plumber's tape.
A pressure relief valve, as the name suggests, alleviates the pressure inside your hot water tank. Generally, hot water produces pressure. In the event that the generated pressure goes beyond the standard safety level, the pressure relief valve acts as a safety element by alleviating the pressure and preventing the water tank from blowing up. If the valve is faulty, it acts contrary to its intended function and begins discharging pressure before the hazardous level. What this means is that hot water will start spewing all over the place, creating a mess around the water heater tank. Often, installation of a new pressure relief valve is the best solution.
Deteriorated or broken gaskets near the heating elements of the hot water heater are also another cause of dripping leaks. Given that elements are hidden behind a cover panel and insulation, it is quite tough to detect a leak around the gaskets. First, the plumber turns off the voltage supply to the water heater. Next, they unfasten the cover panels and shove the insulation to one side. At this point, they have a clear view of the gaskets and proceed to thoroughly inspect them for leaks. Any leaking gasket should be replaced immediately.
Upon inspecting the pipes, gaskets and valves and finding they are in good shape, the next obvious step performed by the 24 hour plumber is inspecting the water tank itself. Note that hot water heater tanks ultimately corrode inside, which causes leaks. When this occurs, obtaining a new tank is the only alternative.
