Homeowners on a budget often ask if replacement is the only option. The answer is a not a simple yes or no. Some water heater issues such as ruptured tanks, leaking pipes inside the tank, or failure due to age, require replacement. Repairing these issues is cost prohibitive – you would pay more to patch an old heater up than to purchase a new hot water heater! Heating element failure, problems with the thermostat, and similar issues may be repairable; saving you money. Ask your Natick plumber what your options are and if repair is an option.
