can you see any water leaking when you look under the tub? it will give you an idea where the leak is but could be tough, when i looked under deck for a water leak it would run along the deck joists along to the other side of the tub.. (one of my lower jets was leaking on the right side but water would run along the bottom to the left what I'm getting at is, if your foam is really wet in one spot it helps the foam turns yellowish and starts to get eaten away by the water but not necessarily where the leak is unless you chip away a little foam.. check around where the motor is if you can and see if an o ring or gasket is leaking hopefully that might just be it, I had to replace those first before I found out I had other leaks and noticed I was dropping 2 inches a day with motors on... hope this helps..

Hello, Thought I'd share the details on this problem...So I was finally able to get back to working on this tub this summer after waiting too long last summer on trying to find the leak and had to wait for warmer weather. The end result was taking the tub out of the deck since it's encased two feet into the deck. first was to cut the front of the deck 2x6's then get my hydraulic car jack and lift the tub then put two 6' 2 inch pvc pipe under the tub and from the other end push the tub out and secure it on blocks.(cement) then fill the tub, run it and look under to find the possible leaks, the good news was 3/4 of the foam was out of it from past repairs and me trying it last summer. found the leaks 5 in total, one the mainifold again due to water from the winter even though I vaccumed all the water and lines last summer which shows it doesn't need much water to crack a line or manifold due to cold. 4 jets were leaking 2 because of pure butcherery by the past homeowner who decided to glue with some expoxy the jets to the tub instead of spending 20.00 to screw it to a jetbody. One leak in the footwell jets due to the blue glue I guess over time giving way or having water in the lines which was not a fun one to work on definitely try to avoid water freezing the footwell jets! and a union ring which was not installed properly where the flow of water goes through behind the heater and motor. So that said the tub is up and running and everything is good oh btw about 35 cans of spray foam were needed to reinsulate the tub and lines. So to say it can be done is true, just be patient and handy and the hard work will pay off. take care LR

Sorry ,, Title should read : Hot Tub leaking about 1/2 inch Overnight....

Ok, first off bought a house and it came with the tub. I've replaced the blower heater rings and gaskets and the water cylinder and thought I was homefree. Filled er up and realized I'm still leaking and know that it's in the footwell. (Was losing approx 2 inches nightly/daily with hottub pressure) Problem I'm having is I can't locate which jet or suction. I have a Cal Spa 8 man tub..4 jets on the bottom and 5 suction thingy's. - Tried fix a leak solution and didn't work for me .. - Tried cutting foam out from underneath and found a trail of water but after chipping away the wet foam it leads to no where! - Tried emptying the tub then getting a hose and squirting water into each jet hoping it would soak the foam.. but to no avail can't find any really wet foam.. that's dripping for me to spot a leak ( This worked in me locating the water cylinder leak right away. without ripping the tub apart. I've put food colour dye in the water .. but it doesn't seem to work This tub is incased in a deck.. and I have been working under it chipping away. Any suggestions without me flipping it on its side and knowing where to look a little better. I have chipped around 3 of the 4 jets and don't get any water leakage...Need a better way to tackle it. Is is possible to shoot dye in with no water in the 9 parts and if so how much so it bleeds through enough to see it past the thick foam in some parts? Help Thanks.. LR
