Fish tank condensation

[campion]

I have a Jebo R362 tank, and everything was going fine UNTILL one day water was dripping out the back of it, it managed to soak 3 large towels!!!
This seemed to have stopped for a few weeks, then yesterday while I was having a coffee, I could hear trickling water.
I looked at the back of the tank, and water was once again pouring down the rear of the tank. I quickly moved all the electrical plugs, and started to mop up the water once again...
I lifted the lid on the rear of the tank and it had lots of condensation.
After a few minutes the water stopped running down the back of the tank and everything is back to normal.
I first thought I had a major leak in the tank, but the water level hasnt dropped.
Any suggestions on why this is happening?
The tank is about 12 months old and everything was ok, untill recently.
Luckly I dont have carpet under the tank, as this would have caused me even more grief.

P.S.
I have noticed on top the tank lid that there seems to be a build up of dry salt. I am presuming this is from the condensation.

the condensation wouldn't be enough to soak 3 towels... and not without water level dropping...

I think it could have to do with your plumbing. Do you have a reverse stop vavle on your airtube that is running into the tank?

Raven is right.

yes I have the reverse stop valves for the air lines, and even if that was faulty, the air pump is BELOW where I have noticed the water was dripping from, it seems to be coming from the top half of the tank, the air pump is situated about 12" above the ground level in the sotrage cabinet underneath the tank.
