Product details

The Waterway Plastics 550-1811 is the flexible hose assembly that connects the pump to a 19 inch ClearWater sand filter. It is built from clear flex PVC at 1-1/2 inch inside diameter and 1-7/8 inch outside diameter.

The two ends

One end carries a 2 inch union, with union nut threads that actually measure about 3-1/16 inches. The other end is a sweep 90 degree elbow with a 1-1/2 inch union nut, threads measuring about 2-9/16 inches. Those measured figures are the fastest way to confirm you have the right hose, since nominal union sizes and real thread diameters do not match.

Two things worth knowing

The 19 inches in the name is the filter tank size, not the hose. The hose has an actual length of 32 inches. And the source is unambiguous that this assembly fits Waterway ClearWater sand filters only, so it is not a general purpose pump to filter hose.

Being clear PVC, it also lets you see what is moving through the line, which is useful when you are chasing air in the system or checking that a backwash has run clean.
