Custom Hoses

We make custom backflow test kit hoses. They have a 1/4” ID instead of the 3/16” ID in the refrigeration hoses currently being used in today's test kits. You can pick from 5 different colors and 3 different ends. Get one with or without a filter, and cut to your specified length.

Our filter has an all-anodized lightweight aluminum housing with a 90 micron brass filter that is both cleanable and replaceable.

We can also repair your current backflow test kit hoses and/or add a filter to it.

We repair and adjust all models of backflow test kits with normally a 1-3 day turn around.
