I have a Kreepy Krauly classic that is currently connected via a skim plate and it works great! I have an unused poolside 1 1/2" threaded female PVC fitting that at some point under my concrete pool deck is reduced to 1" PVC and goes to the pump & filter where it is capped. This line was apparently used previously by a prior owner for a pressure driven cleaner which was replaced with a Kreepy.

My question is: If I connected this 1" line to the existing 1 1/2" skimmer line with appropriate valves and / or regulators to balance the flow, would I be able to successfully run my Kreepy using the 1 1/2 " poolside fitting and not stress the pump?

I have searched the web extensively and could find no conclusive information regarding the feasibility of doing this. I would appreciate any and all advice. Thanks.
