Waterway 2" non-return valve for blower line

This non-return valve is often installed to help keep water from getting into your spa's blower. It is installed on the air-line between the air jets and the blower.

The ends of the valve have an outside diameter of 60 mm, and slide neatly inside the sockets on 2" female pipe fittings.

The manufacturer says that it has a 1/4 pound spring, in case you are interested. We have found that it works well with most commercial and domestic blowers. You should also have a loop of air pipe above the water line, as an additional precaution against water reaching the blower.
