Thanks, Spa Guru. Yes, it is on concrete. Are there usually two manifolds (I think that's what those octopus connectors are called)?

Last summer I pulled out the spay foam and replaced an octopus and 8 (I think it was) adjoining tubes that had exploded due to ice. I have a 2000, beachcomber 550c and the repair seems solid. It is, however, still leaking somewhere!!!! Does anyone know the layout of tubes under all this spray foam? Is there another low spot that would be good to check first or do I need to pull out ALL the insulation? Any help would be appreciated. GREATLY!!! Thanks, Claire
