I don't believe that they are available anymore. I have a complete housing that I can part with. PM me if you are interested in buying both pieces.

Ross,
If Scotts offer doesn't work or if anyone else's doesn't and you still have the housing, an alternate is a repair. I've had excellent results with Devcon metal epoxy putty. Way back, I used lots of it on cast iron pump housings, volutes and impellers that were eroded from cavitation. I remember one where the housing was eroded completely through. |

Ross, Out of curiosity, what was wrong with it and how did you repair it? |

So while investigating a wandering temp gauge i was inspecting the thermostat and upon reassembly broke out some threads and chunks of the mating surface around one of the mount holes. Turns out the mounting bolt was broken off and much shorter than needed. I drilled out the broke off bolt and re threaded deeper. Filled the voids with liquid silicone gasket and with a new paper gasket got it to seal. There was just enough flange left around the thermostat to make it work. Upon my test run discovered I was sucking air through my raw water strainer causing the irregular temp fluctuations I was investigating in the first place!

How did you determine you were sucking air at the strainer? Air bubbles or something else?

Ya air bubbles running through the clear housing of the flush pro. When I rotated the strainer the bubbles were gone!
