Inline Pressure Reducer
For all installations a pre-assembled Inline Pressure Reducer Kit is provided.
The Inline Pressure Reducer Kit includes the following:
1) Pressure Reducing Valve (PRV), ¾” NPT that regulates outlet pressure to 4-psi
2) Coupling ¾” PVC, adapts PRV to provided barb fitting
3) Adapter, ¾”MT x ¼” Barb, HDPE, provides connection to ¼” hose and PRV/Coupling
The kit should be provided pre-assembled. If assembly is required, wrap both ¾” NPT
threads on PRV and Adapter with Teflon Tape. The tape should be wrapped 3 times (3X)
around the threads. Screw one end of the Coupling into the PRV and then screw the
adapter into the other end of the Coupling. Connections should be hand tight with an
additional ½ turn utilizing a wrench or channel lock pliers. Connect one end of the ¼” hose
to the ¼” barb on the Adapter and the other end to the ¼” barb water inlet fitting on the
RIO Zuni. Use hose clamp or cable ties to ensure barb connections will not leak. The
pressurized feed water should be connected to the unused end of the PRV, this connection
size is also ¾” NPT. Proper fittings should be utilized that can handle appropriate feed
water pressure.
NOTE: Check all fittings for leaks prior to operating the RIO Zuni.
