If it only leaks with the pumps on it is a pressure leak, which is not the gasket. I would stand it up and see, the leak point will be discolored. Plan to replace, not repair with epoxy or some flex seal stuff. Unless you want to do it again next year.

Thanks

you wouldn't happen to have a pic of what discoloration  of the leak looks like exactly

 

I'm off next week so weather permitting I plan on probing  from the sides with some dowel  to find the wettest area(s)  and if possible tunnel in from the side

what would you recommend  I replace the spry foam on the bottom of the tub with?  a small hole I can re-foam but if the areas large  the foam kits are expensive here 

 

I have pretty good side access due to previous owners rodent problem

  pics from reconstruction long completed    this was a test frame and fill  bottom corners are round

I am West of Milton. If you can't get at it from the sides while down and in place you might want to flip the spa completely over. The Sundance and Jacuzzi bottoms are part of the structure and if stood up without the bottom on the frame work might flex off square and you could have trouble getting the bottom back on depending on how old and rotted (if rotted) the wood is. 

Remove the foot well jets and pump return covers and try and get a good look at the seal in between the jet body and acrylic to see if the seal/o-rings are deteriorated. As a hail mary run a bead of marine grade silicone around the gaps in between the acrylic and jet bodies, pump returns and around any lights. I would try this before standing/flipping the spa.

the spa controller and that black plastic its attached to is in the way for side access and its a LONG reach!

I redid all the wood when I got this spa as it was rotted so it supports itself fine on its side

I'm not convinced its the seals between the tub and jets  as it 100% leaks when I run the footwell jets When the tub is left idle  the water level does NOT drop

 

I'm in Ajax  can you recommend anyone out this way? be a long drive for you!  if I cant get this fixed myself

Try leak seal liquid, no joke.  I have a 1988 CalSpa and have had a leak at the side 8" from my home's wall - of course; so I have used leak seal up to twice a year for over a decade, it does work.  I've used both these brands, and I buy online.

The footwell jets are notorious for leaks, and a huge pita to fix.

you mean the two under the lounge seat?  see pic  is the actual jets or the lines/fittings  or the jet gasket in your experience? because I would need to order parts that can take me weeks to get. looks to me that the ONLY way I can get to it would be to tip it up again and tunnel in from the bottom....  My concern is that while tipped up I cant have water in it to see the actual leak(s)

do you happen to know the part numbers of those jets or what they call them  I would like to look them up in a parts diagram so I can see what's involved

 

the pic is when i got the tub  its currently down and being used

Hi  I hope someone here can help

 

I got a 2001 sundance altamar for free this spring  it needed work had 2 leaks which we fixed and enjoy it twice a day

I had noticed water level dropping about 1.5-2 inch per week but chalked it up to us using it so much.  I had  the sides off  and poked around and noticed the foam is wet on the bottom nearer the middle

a lot of the foam was removed on the sides of tub due to rodents (previous owner said) I repacked it with roxul  insulation  the roxul is bone dry

we left the tub off for 48 hours after making water level  it did NOT drop

we ran recirculating pump for 24 hours  NO drop

we ran the 2 speed filtration pump for 12 hours NO drop

we ran the 1 speed pump (message seat and footwell jets) for 12 hours water level dropped   (i had diverter in the middle  now I will pick chair then footwell jets to figure out which side)

this "circuit"  has the message seat jets which were dry when i opened it and the 2 foot well and one side jet side jet was also dry  there are also 3 suction lines

I have tried fix a leak 3 times no luck

its getting cold here (Toronto Canada) so I want to try and fix before winter  I plan on tunneling into the foam where its wettest as there is a suction line a foot or so in

 

anyone dealt with this tub any plumbing diagrams?

  I would prefer not to tip it up but I may have to if leak is on bottom middle   this thing weighs a ton!
