Waterway Top-Load filter
Many Waterway's Top-Load filters have a built-in by-pass which is spring-activated and allows 100% water filtration on the low speed of two speed pumps. When the pump is running on high speed, the spring opens, allowing unrestricted flow and maximum hydrotherapy action.
The filter must be installed on the pressure side of the filtration pump with the flow arrow on bottom manifold pointing in the direction of water flow.
