It's a
Raritan PHII. If it was built before 6/92, it needs kit PHIIRK. If it was built AFTER 6/92, it needs kit PHIIRKC. And it's important to get the right one, 'cuz not all the
parts are interchangeable.. If you don't know its age, give Raritan a call. There should be a
serial # somewhere on the
pump, but don't worry if you can't find it...their tech support guys can still ID it. 800-352-5630 x 3
As long as you're rebuilding it, it would also be a good idea to replace the corrugated hose and cold
water hose--neither of which are rated for below-waterline connection--with sanitation hose. Sheilds or Trident #148 flex PVC is fine for your flush
water inlet hose...If replacing hoses is a job you only want to do ONCE, go with a
toilet discharge hose that's proven to be
odor permeation resisitant. It'll cost you a bit more, but definitely worth it. Raritan SaniFlex
RaritanSaniFlex hose would be my choice. Defender has it for <$10/ft.
