This is my first post but I am sure I can get some help here. I am following the TFPS methods as near as possible and have been incredibly pleased with this great resource. Thanks to the organizers.
Here is my problem. I have an in-ground pool, about 30-40,000 gal. Pool was built in late 1960s, maybe - when house was built - so I don't know the exact age of the equipment. It has been mine for 4.5 yrs. About a month ago I found a very rusted bolt-like thing in my pump strainer basket. A couple of weeks ago I realized that my pump (Century Centurion 1 1/2 HP) was running but not pumping through the filter (0 psi pressure and when I opened the air bleed valve it actually seemed to be sucking rather than blowing). This morning I finally had time to open up the pump (which seems not to have any manufacturer label - but it looks a lot like the Pentair Dyna-Pro schematic I found on-line) and motor and look for the problem. It appears that the motor has a female thread at the "impeller end" of the shaft and the impeller (C105-236P) has female threads on the side that faces the shaft. I am apparently missing the threaded coupling that should attach the two parts. I am having trouble finding a source on-line that shows me that type of connection and my local pool store kid was useless...without a SKU for the part. That was apparently what had worked its way - upstream ? - to basket...???
Any one familiar with this type of impeller set-up and/or any guidance on where to look for the part?
Thanks in advance for the help.
