I posted this earlier, but it didn't get there. I have a Cal Spa.

I have a leak in the pvc piping behind a 7" jet. The backside of the jet has a housing with four fittings and lines running to them. (1) 2", (2) 1 1/2" and a 1". The 1" is leaking. They lines are flexible ribbed lines fitted into couplers and/or elbows. How would you remove these and then reseal them. I don't think I can find another housing like this one. Is there a special glue for this flexible tubing and can I buy this flexible tubing if I cut some of the old off. This is a critical problem due to the weather getting cold and the leak tripping the GFI so I can't turn on the heater. Please help me.
