What do you guys think of this response?The XF will take 2.5" pipe on the inside or a 3" coupling to the outside of the union.
You will need to make sure that all suction plumbing is big enough. Depending on the number of lines, you should probably use 2.5” or 3” plumbing.
You should go to a 420 square foot filter. You might want to use a spring check valve to bypass the heat pump and the SWG cell.
Make sure that the various return lines are valved so that you can control the flow to each feature.
Make sure that the plumbing to each feature is sufficient to provide the necessary flow without exceeding a water velocity of 8 feet per second. All suction lines should be sized to keep the water velocity below 6 feet per second.
“We use 2” lines and you will have no issues getting the best flow to the spa spillway because we use more returns (4) than most builders giving the pool and spa more circulation and water flow. The pump allows you to control the speed and flow of the water to the features.
