Thanks for the responses! I bought the exact equipment recommended by JVTrain, the last of it should arrive Thursday. I'll update after I finish. A couple quick follow-up questions.
First, will a pump's impeller impede the flow of air when you are trying to blow out lines? That is, if I'm only blowing from the skimmer, will I really get enough air all the way through to blow out the valve, heater, aux pump (cleaner), and return lines. I can control the flow of air so it's not like the heater and aux pump have to be done at the same time. But I still thought the main pump's anatomy (impeller) would greatly reduce airflow.
Second, I have a multi-port valve on the side of my sand filter. Should I change the valves position at all during blowing to blow out the other operational states of the valve (filter, backwash, waste, rinse)?
Thanks!
