This past weekend I noticed something odd when using my spa. I dont know if this issue has been present all along and I am just noticing it now, or if it is a new issue.
When I run my pool in "pool mode" (meaning the suction comes from the pool and the return goes to the pool) I see absolutely no air in the gasket at all.
If I have it set in "overflow mode" (meaning the suction comes from the pool but the return is from the spa) I see absolutely no air at all in the gasket.
But when in "spa mode" (suction from spa and return to spa) I see a decent amount of air in the gasket. It doesnt seem like I am leaking water anywhere...
Also, a lot of times I crack the suction just a drop in order to account for displacement. I allow just the slightest bit of suction to come from the pool which slowly refills the spa. When I do this, I see absolutely no air in the gasket. Its only when I have the suction coming 100% from the spa that I see this air.
Is this something to worry about and look into further, or could it be air that's trapped in there and really no big deal. If its been like this for 2 years since I put it in, I wouldnt think twice about it. But I dont know if its a new problem showing a leak in a pipe somewhere or something.
Thanks a million.
