Was having low flow issues and consulted guy at local pool store (bought the unit online, but store is still very helpful). Suggested that I might have an airlock somewhere in the system, one thing I could try was to remove the drain cap (the one at the bottom of the filter that the manual said was used for draining for winterizing). Water is flowing out of it, so any airlock I might have had it probably gone, but I CANNOT get the cap back on. It is threaded, but only one side of the threads seem to be "catching." Am I just going to have to wait for the filter to drain completely before I can put the cap back on (system is plugged so filter is currently draining).
Please tell me I didn't ruin this on day 1. I was at least hoping to make it through the first week. =D
