I have a Tiger River Spa- Bengal '99 with a slow leak ( about an inch in three days)

I would appreciate any suggestions in finding the leak including a plumbing diagram.

The access to the spa is difficult...it is enclosed in a deck. Is is possible to find the leak by going in the side? Do I have to go through the bottom?

Thanks

First make sure it's not the light lens. If it is it won't leak into the motor compartment, it will seep out behind the compartment and fill up the foam, and leak out through the lowest point.

Check for calcium deposits and residue around the lens from the inside of the compartment.

I checked the light lens from the inside it was dry....

The leak appears to be at the base in the front of the tub..slightly to the left of the drains....any suggestions?
