I have a 2003 Marquis Spirit Spa that I've been trying to get back up and running. After replacing all the o-ring seals and getting a new ozone device, she worked great...............until. There were no leaks from the reinstalled motor/heater connectors but there is an open pipe behind the pump that started leaking. I don't know where it leads or why it's there. It's always just been there but never leaked. I don't know why it's not capped either. 2 1/2 inch with what looks like 4 smaller pipes leading away from it, almost like a manifold of some kind. I have posted pictures. I plan on shooting some water up there to see where it comes out but I'd rather just cap it. Unless it's an air intake of some kind. Marquis was no help whatsoever. Thanks!
