I bought a Marquis Quest spa used but in excellent conditon. After the move there was slight leakage where the PVC piping connects to the control box. I hand tightened it and it is now dripping very slowly. Does anyone know the best way to tighten this connection?
Also, the Tri-zone selector knob/switch was very hard to operate. In trying to change the zone the plastic insert broke off. How hard is it to replace this and how do you get the plastic housing off of the spa without breaking it. I looked for repair manuals on line but did not come across any. Any help will be deeply appreciated. Thanks.
