If your water heater is starting to get noisy, then you should be worried because it might be indicative of some serious problems. Your water heater might be only moments away from a short circuit that could damage all of your circuit breakers. There might also be a buildup of sediment in your water heater, which may cause the use of excess electricity and rack up your utility bills. You can solve the problem temporarily by draining the entire system and then refilling it. However, the only surest solution is to call Narwhal Plumbing so they can send over a specialist to have a look at the problem and come up with a permanent solution.
