Thanks for the responses. to answer a few questions: There are no visible leaks inside the equipment compartment. The noise is also difficult to hear inside the compartment... it's almost like the wood deck is amplifying a vibration and "creating the noise" under the deck. Topside- there's really very little audible noise. I'm going to try to isolate the vibration using a rod (up to my ear) on all the components to try to isolate the point of greatest vibration and perhaps find it that way. As to the leak- it definitly seems like I'll need to dig out some foam but I'm not sure how to best go about it. 1) some suggest - drain the tub, unhook the wiring and tip it on it's side- start digging. Easy enough but how the heck do you find the leak if theres no water in the tub OR track wetness if the tub is now in a different orientation? Won't the flow of wetness change making tracking it hard? 2) I could pull the sides and start digging that way but the sides don't appear to be easily removable? Do you just break the planks glue joints? 3) I could raise and support the tub with minimal water and dig from underneath it... doesn't seem especially fun or safe. I guess I'm looking for some ideas on how to start. Thanks

Anyone?

First post so be gentle- sorry for the length. I have a 2006 vanguard which has been great. Two winters ago, we had a really cold winter and the tub sits on an elevated wood deck which is pretty exposed. In the spring of 2011, we noticed a leak which appeared to be coming from the right side drain. After much research and contacting the local dealer, it was determined that the pipe behind the drain plug had cracked (freeze damage suspected) and it was patched. The leak improved greatly but we continued to see a very small drip under the deck. We were told it could be residual water and it was so small (maybe 1 drip every 30 seconds to 1 minute) that we just went ahead and monitored it. The tub lost almost negligable amounts of water considering we were using it . It would drop about 1 inch per month. Yesterday- I went under the deck on another matter and could hear a noise which sounded like a distant plane... and again saw that the drip is still there. The tub was on meaning- it's power up and to temperature but the jets were off. I went topside and could hear nothing at all. If i put my ear up to cabinet, I can hear the circulation pump hum but, under the tub, the noise is much louder. The dealer tells me it's possible but unlikey to be the circ pump as it has a bearingless magnetic flow??... they are also suggested this pour in stop leak where the drip still exists... which i'm skeptical about. Could anyone offer some guidance? I'm thinking the circ pump needs to be replaced and the leaks source needs to found but given that it's so small- I don't want to spend a fortune chasing ghosts but I'm willing to dive in myself if I could get some guidance. Any help appreciated.
