    Hayward Combo Adaptor Check Valve

    Item # E1834 Manuf.# SP1091CV

      Our Hayward SP1091CV 1.5" Male Threaded Combo Adaptor and Check Valve is ideal for use with chemical feeders installed on above ground pools. The Combo check valve has a 1.5” male thread on one side, tapered conical adaptor on the other. The tapered side is designed to fit 1.25” or 1.5” flex hose. There is a brass and rubber check valve in between. Use on the output of your chlorinator for above ground pool systems or in ground systems using PVC flex hose. This keeps concentrated chlorine or bromine from “rolling back” to your heater or pump when your system is turned off and prevents corrosion of your pump shaft seal and heat exchanger. Check valves also help your system to stay primed. Use Teflon tape on the threaded side for hassle-free, leak-free installation. read more
