Upon arrival to the home after talking with the homeowner he had this water heater installed in 2016, the power light had went out over the weekend but was able to be relit and the heater was functioning as it should, the water heater is a ream I did inform the homeowner that we have had problems with the rains in the past and if this happens again we will need to do a proper diagnostic as well as possibly replacing the gas valve the customer stated since the water heater is functioning properly now he does not want to proceed with anything else and will let us know if this happens again
