I have a Hot Spring Spa Envoy 2006 M# KK3H1550. Leaking from bottom of side panel. No leakage inside the equipment area. I did drain the spa in stages until it stopped leaking at the small jets at calf level in captains chair. So am I going to have to jack up and block the spa and dig out foam to find this leak? Is there any thing I can do to test the jet ports and possibly correct the leakage from the outside?
