There are some downsides to running in-floor cleaning. It generally requires an oversized pump. Plumbing in Solar can be a lot more troublesome if you don't plan for it ahead of time.

My advice, if you do go for in-floor. 1) you still want regular returns (maybe deep returns of you want to do solar.) 2) you still want a dedicated vacuum port. 3) You may want to consider a second pump to run the in-floor. 4) Take a look at the diagrams on powermat.com for systems with Solar and in-floor. Even if you don't plan to do solar, you never know when you might want to in the future.
ok.. I was doing good until I got here and this is where you lost me. What does solar have anything to do with Paramount in floor? I live in South Carolina and don't have any use for a pool heater. Can you please clarify these statements for me? Otherwise, the advice is great..Thanks
