I have a Cal Spa Eliminator series spa that I purchased in 1995. I have sprung a leak on one side and since we enclosed it with a building I cannot get to the outside of the spa on the leaking side. I believe it to be a jet that is not sealed good. I contacted Cal Spa in California for a copy of the schematic and I was informed that they had changed owners and did not have any old paperwork. Will someone tell me how to undo the jets and reseal them?
