The overflow value of our water heater (Rheem installed by Fast 11 years ago) had malfunctioned recently. When we called Fast for a repair, we were told because of the age of the heater we would probably need a new heater. When the technician, Gordon, checked out our situation however, he felt we had another choice. The overflow value and the expansion tank needed to be replaced for sure, but our water heater appeared to be working well and was likely to last a few more years -- though no guarantee of course. We appreciated having an alternative to heater replacement based upon his experience. Repairs which included the expansion tank were much less expensive than replacing the water heater in addition. We felt comfortable with Gordon's clear explanation of our situation and concern about our needs. We will continue to use Fast in the future.
