I am thinking of installing a Pump Timer on my pool system, and was wondering if it's important to have my gas heater shut off prior to my pump motor. The heater does have a pressure switch which shuts down the heater if the pump is not running. Someone mentioned to me that the pump should run for about 10 minutes after the heater is shut down, to not leave hot water in the heater pipes.
Thanks in advance for the advice - Irving
