Air Lock Return Jets on Inground Spa?


Aug 25, 2020
Philadelphia, PA
Potentially attempting to close the pool for the first time myself this year. In previous years, my pool guy lowered the water about 6" below the tiles, which is definitely not low enough to go below the inground spa return jets. So, my question is, do I blow them out and plug each one? Or do I blow them out and close the valve to the spa return jets which (in theory) would air lock them... I think???
