Pulsacoil taking 3 hours to fill a bath.

The reason I turn the three switches off when I'm done with my shower or bath is that the timer has three timer settings.

To find out if the system is working correctly, I think you need to leave the three switches on, and rely on the timeswitch. The Gledhill has some kind of control circuitry, I don't know what it does.
