Ditto, it was in fact the valve. Took it apart, replaced with new freshly lubed rings, re-oriented the handle properly and no more bubbles What a weight off my shoulders, and quite the learning experience along the way! Just got done spending about 5 hours on the valves/filters/vacuuming/scrubbing the pool and finished off with a fresh gallon of clorox and leaving the pump on for the night. My taylor testing kit came in as well so I'll be spending this week getting the water quality dialed in and hopefully be swimming by the weekend! Thanks to everyone who helped me along here; again, so much learned.
