Includes a high flow injector, and a unique, state-of-the-art variable flow rate bypass check valve which automatically adjusts flow, allowing our manifold to be used with pumps in the widest horsepower range (far superior to old style manifolds using a manual valve). Unit is suitable for either 2" or 1.5" spa plumbing because we include a pair of reducer bushings at no extra charge. Has standard 1/4" barbed fitting for ozonator supply line.  Others charge up to $200 for units with less efficiency.

Product notes: Locate manifold after the filter, pump, and heater, as shown in flow diagram, by cutting out a section of the existing spa plumbing.  Install using PVC cement. Most other manifolds use fixed flow rate valves, and therefore will not function equally well with pumps of different HP ratings.  All this, yet we still charge much less for our Universal Manifold! (2) 2" x 1.5" PVC reducers included.
