Pool/Spa Spillover Dam Height

Postby freerangequark » Fri 16 Dec, 2022 15:34

When my pool was recently rebuilt, the spillover dam from the spa to the pool was set too high.

When the spa goes into spillover mode, the spa level rises and water leaks out the spa under the spa's cantilever deck and into the ground.

The pool water level is set at 2" height through the skimmers 6" tall opening.

The dam/spillover is at 2-3/8" above the height of the pool water level.

The spa water lever is 3/8" below the spa's cantilever deck.


QUESTION: I am having the spa spillover dam height lowered. To what height should it be lowered?

Thank you,
Glenn

Seems like a poor design
The pool water level is normally set at 1/2 to 2/3 through the skimmers 6" tall opening. That is 3" to 4", but that's not possible with the spa level
I would be inclined to reduce it by 2" to keep it just above the pool level
