PLEASE HELP ME!
I'm still having issues that I simply don't seem to be able to resolve. Desperately need advice/guidance...
1. SPA DRAINS. Whenever the system is shut down, spa empties to pool level. It also drains when I tried running it in spa mode. As long as the system is running in pool mode, all is well. This is a recent problem, began intermittently, has become permanent. Never had this problem ever in the prior 5 years. STEPS TAKEN: Replaced the check valve, even though it looked great when I opened it up. Planning to open up the pool/spa return valve as it seems to be the last possibility. What exactly am I looking for? Could it be anything else?
2. CHECK VALVE DRY. Noticed this morning that there was no water in the pool/spa return check valve and it was literally bone-dry (system was running in pool mode at the time). I've never seen this happen, but I have noticed recently that even when there's water in the valve, it doesn't seem "full" and I never seem to see the flap engaging in any way, regardless of system mode.
3. DE BLOW-BACK. After backwashing the filter today (temporary measure until ready to clean fully in the next day or two), I returned the push/pull valve to the normal circulate position. Decided to open the pressure relief valve to make sure all was well. As soon as the air began to flow through the valve, I saw DE entering the pool and spa through the returns/jets. The system was not running at the time. It happened while the pressure was releasing. When the system is running DE does NOT come out of the returns. I don't recall ever seeing this happen before.
Incidentally, I do have a small 1-inch air bubble trapped between the ribs of the pump basket lid. It's always been that way, from the very beginning, so I haven't ever given it much thought. Seems it has nowhere to go due to the ribs in the lid, but maybe I'm missing something.
Please help me. I've got less than a week until I leave the country. At this rate, my only option will be to keep my system running 24/7 which I'd really rather not do.
