It just dawned on me I don’t know where the cylinder is. Why would they take it? We have never used them before but they come highly recommended.I’m confused as to what it is supposed to look like. Are all the holes supposed to be plugged? They are supposed to use different plugs? They poured antifreeze in there on top of the plugs which seemed odd but I have no idea what I’m doing here.
Look at the previous posts. Yes, there is a cylinder in the port. The middle piping is where water is return to the unit. The cylinder spins, therefore allowing each head to pop up at a different time. Check where they store your other items and definitely give them a call.
3. Remove module(s) from valve housing(s). Store module in dry clean area out of the winter elements for winter until reinstallation in spring. (See Fig. 2)

Do you know if when the system is operational, if the 6 pop up heads in the pool rotate one after the other? If so, then you have a cylinder. If not, you never had one to begin with. Hard to tell.

In item # 3, you will find a picture of the module to the left. Click on link. The model is what spins based on water pressure and velocity. If you had a hose with a 4 port extension on the end and opened one valve and a time, then closed and moved to the next, it would basically work the same way.
