We recently purchased a house that came with a Beachcomber 530 hot tub. The hot tub turns on, heats, and doesn't have any leaks from the basin. However, underneath the part below there is a large leak underneath the air control for the neck massager. It appears as if the seal has gone bad. I am unsure of whether this part unscrews or just pulls off. There isn't a screw to release the piece to get at what's underneath. I've thought about trying to make a permanent seal underneath this part without removing it but haven't come across a product that can resist the heat and pressure. Any suggestions on what I might do to repair this? Also, where might I find such parts?
thanks in advance. A photo of the part in question is included. The leak happens at the bottom of this piece and sprays out in all sections.
