ABSTRACT:
A water system comprising a hot water system, including a hot water heater and a conduit coupled to feedwater under pressure for conducting water to and from the hot water heater. An injector pump is coupled to the feedwater under pressure and has a water port coupled to an inlet port of a reverse osmosis module and a brine port coupled to a brine outlet port of the reverse osmosis module and to the conduit. The injector pump provides water to the water port of the injector pump and increases the pressure of the brine at the brine port of the injector pump to greater than the pressure of the feedwater so that the brine can be injected into the hot water system.
