Raypak Tube Bundle [156A Polymer Kit] (014875F) miscvalves An impeller in this role

An impeller in this role is useful because it is directly responsible for how the pump converts motor power into water flow through the wet end

supporting water flow while allowing debris interception ahead of downstream equipment

and this Flo Control valve is designed with 1-1/2 inch slip connections and a 1/2 pound spring rating using the 1011C15 reference

That helps restore one of the cleaner’s most important working connections with a direct replacement

supporting a cleaner and safer finished installation

Raypak Tube Bundle [156A Polymer Kit] (014875F) miscvalves An impeller in this roleThe Raypak Tube Bundle [156A Polymer Kit] is a replacement heat exchanger tube bundle kit for compatible Raypak 156A pool and spa heater systems. The tube bundle is a central heat transfer component, allowing water to move through the heater while absorbing heat from the combustion process or heating assembly. This polymer kit is typically used when the existing tube bundle is leaking, scaled, damaged, or no longer transferring heat efficiently.
