There are often a number of different causes for the same condition, so be sure to check them all -- even after you have identified the main reason for the problem. Some may be on the verge of developing, while others may develop right after you have fixed the primary cause. So play it safe...CHECK ALL CAUSES! We recommend that you rely on an experienced professional plumbing and heating contractor for water heater installation and maintenance.

National electrical code requires two grounds: (1) to water system. and (2) to metal stake driven in ground. Be sure all wiring is sufficiently heavy. Connections are clean and secure. There is no excuse for poor grounding: Better to be safe than sorry.
