I closed my pool yesterday. I have 3 returns and two skimmers that were blown out and plugged flawlessly. However I was unable to get my Polaris line bubble free while the blower was running after I plugged it (I tried 5-6 times using new teflon tape and even some lube on the o-ring, and changed the o-ring). When I turned off the blower, there were no more bubbles coming from that plug. Seems tight so I put the cover on.
Should I be concerned about this?
