Picked up a Hayward Power Flo II 1.5HP VL2285 (Power-Flo II | Hayward Canada) on an end of season deal.
Here is the PDF manual: https://www.hayward-pool.ca/assets/documents/pools/pdf/manuals/power-flo-ii-isvl1285.pdf
(parts breakdown page 11 and 12)
The connection to the pump uses SP8100 series connectors. Based on what is molded on the parts and what I found out online,
SP8100UNN - nut
SP8100UNO - oring
SP8100UNB - barb adapter (Accepts both 1 1/4" hose and 1 1/2" hose.)
SP8100UN? - slip adapter (accepts 1 1/2" PVC pipe inside. Outside is 2 1/8" which does not appear to match up to any dimensions for 2" PVC pipes or couplers.)
These components are available in various kits:
SP8100UNPAK - 2 nuts, 2 orings, 2 barb adapters, 2 slip adapters (This is what came with the pump.)
SP8100UNBPAK - 1 nut, 1 oring, 1 barb adapter
SP8100UNSPAK - 1 nut, 1 oring, 1 slip adapter
Sometimes these parts are referenced with SPX8100 or SP8100. I'm not sure what the difference is there??
I was going to do 2" PVC on the suction side. Why? Why not! Redoing the plumbing in the spring anyway to add in this pump and a 21" Hayward sand filter, so might as well do 2" on the suction side. I could use the slip adapter, a short piece of 1 1/2" pipe, bushing up to 2" and go with it. BUT, why have that reduction to 1 1/2" and introduce extra friction (likely minimal, I know) if I don't have to. So I went looking for an adapter to use.
In my mind, I am picturing a female coarse thread which mates to the pump and a male external thread which takes a larger union, like the SP1500 series (which just happens to fit my Hayward skimmer and accepts a 2" PVC coupler!) I thought I had found the solution with (https://thehottubsuperstore.com/product/hayward-pump-union-adapter/). When it arrived, the fine Hayward threads were a perfect match to the SP1500 series Hayward union. But the internal threads were still too fine to mate with this pump, although the diamater was almost perfect.
So now I am back looking and searching....
Anybody know if there is an adapter out there that would work?
If I can't find an adapter, my next idea is to glue a 2" long piece of 2" PVC in a 2" PVC coupler. Throw it in my lathe and bore that piece of pipe up to 2 1/8" so that I can glue the SP8100 slip adapter inside it!
