While replacing the Hot water heater in 7956 a homeowner reported that they had to wait for the water in their shower and kitchen sink to heat up.

This was documented in a previous article. 7954 Leak Repaired on Re-Circulating Pump – Park Villas North

It was discovered that the recirculation valve was turned off. Once the valve was turned on, the circuit breaker to the recirculation pump was reset, and the system was bled of excess air in the system it started working properly again.

The additional cost of the electric needed to operate the re-circulation electric pump is minimal when compared to the wasted water wasted.

Please be sure to hire contractors who understand these systems so that they perform properly. If the job is not done properly, then everyone in the HOA community pays.
