ABSTRACT:
A time shared arrangement for delivering spa water and pool water to a water heater is disclosed in which check valves respond to the presence of spa water and pool water pressure. Water drawn from the pool is diverted into two streams, one passes through a check valve to a water heater and the other passes through a check valve to a return line. The flow of pool water to the heater is isolated by a further check valve forced to a close position by the pressure of the pool water. Water drawn from the spa is diverted into two streams, one passes through a check valve to a water heater and the other passes through a check valve to a return line. The flow of spa water to the heater is isolated by a check valve forced is closed by the pressure of spa water. Separate check valves are used for the diverted flows of each water stream to reduce pressure loss and provide a uniquely located site where a signal can be derived indicated by operation of the spa water pump or in the absence thereof a control parameter indicative of operation of the pool water pump.
