Product details

The Waterway 550-1831 is a PVC flex hose assembly, the piece that carries water from the pump to a sand filter. It is supplied made up, with a union fitting at each end.

The two ends are different

One end is a 2" union. The other is a sweep 90 degree elbow carrying a 1-1/2" union nut, which is what lets the hose turn into the filter without a separate elbow. The measured thread figures are given as about 3-1/16" on the 2" union nut and about 2-9/16" on the 1-1/2" union nut, which is the practical way to check it against your own equipment. The actual length of the assembly is 38".

Check the filter size before you order

The source names this hose two different ways. The product name and the detailed description call it the assembly for 26" sand filters, while the page metadata and the image caption call it 22". Both readings are on record, so take a tape to your filter and to the union threads rather than going on the title alone.

Questions and answers

What people ask about this product, answered by our pool techs.

Is this for a 22 in. or a 26 in. sand filter?
The source is not consistent. The product name and the detailed description call it the hose for 26" sand filters, while the page metadata and the image caption say 22". Measure your union threads against the figures listed here before ordering.
What are the two ends?
One end is a 2" union. The other is a sweep 90 degree elbow with a 1-1/2" union nut.
How long is it?
The actual length is 38".
Why do the union nut threads measure bigger than the union size?
Unions are named for the pipe they serve, not for the thread. This listing gives the measured figures, about 3-1/16" on the 2" union nut and about 2-9/16" on the 1-1/2" union nut, so you can check them directly against your equipment.
