Forum Title: First time winterizing questions
As you can see from the picture I have ports to use for winterizing. I have gizmos for the two skimmers and black plugs for the four returns. I drain the pool just below the skimmer since I have an autocover. Blue S1/S2 = skimmers (valves purple) and MD=main drain (also valve purple) Green = Returns (2 are on one line; the other 2 are separate) Red = blow port for cycloneI have a few questions:Blowing lines: Do I need to block off the suction side while I do the other side or is the cyclone powerful enough to do all at once? Do I need to shut the cyclone off/on at certain times or just when doing the last line? S7D75 DE Filter: I assume filter should be on recirculate when blowing the lines? How do I clear the in/out lines into the filter or do they drain as the filter drains? Can I start with draining the filter prior to blowing the lines?Antifreeze: How much RV antifreeze should I add to the return/skimmer/drain ports? Main drain: Do I add antifreeze to the main drain line port or do I airlock, then add some antifreeze then blow and airlock again? Thanks for your help!

I have a few questions: Blowing lines: Do I need to block off the suction side while I do the other side or is the cyclone powerful enough to do all at once? Do I need to shut the cyclone off/on at certain times or just when doing the last line? Click to expand... I have never tried this, as I isolate each section (Suction & Return), but the Cyclone should be powerful enough. Shut it off at the last line. The main drain will probably blow last as it produces the most resistance. S7D75 DE Filter: I assume filter should be on recirculate when blowing the lines? How do I clear the in/out lines into the filter or do they drain as the filter drains? Can I start with draining the filter prior to blowing the lines? Click to expand... Everything drains while clearing the lines. When done, remove the drain plug for the excess water. Remove the pressure gauge as well. Antifreeze: How much RV antifreeze should I add to the return/skimmer/drain ports? Click to expand... If you wish to use antifreeze, follow the instructions on the bottle. Usually not recommended unless you are in a really cold climate. Main drain: Do I add antifreeze to the main drain line port or do I airlock, then add some antifreeze then blow and airlock again? Click to expand... Only if you wish. Usually not recommended either. If you break the lock, then water will come gushing back into the pump, so kind of defeating the purpose. Released trapped air will act like a siphon on the way back. Try it. Clear the line, lock it and open the lock with the pump lid on and see it fill up.

I'm still a little unclear...if the filter is on recirculate while blowing the lines doesn't it bypass the lines going in and out of the filter? thanks!

No, it bypasses the filter DE grids, or the cartridge, or the sand (you have a DE) and not the plumbing configuration. It is like having one straight run (kind of). The waste setting would bypass everything and water or air would be discharged from the back wash hose-line.
