Hi! I recently had my old brick spillover replaced on my spa with a travertine spillover. While the water used to spill over the brick with more distance from the wall, the new situation has the water spilling over just a few inches and then running down the wall, even at 2700 RPM. The pool builder put a rounded edge on the spillover and now says that edge needs to be cut off. They say a sharper edge will let the water flow straight over the stone and give a waterfall effect.
Does the physics of that sound right, or is the spillover too wide regardless for a waterfall effect?
Also, a local pool guy told me I should just block up all the return jets in the main pool to force all the water to return through the spa jets, which would solve my problem without needing to cut the stone. Does that sound right? Doesn't that create a circulation problem in the main pool? I have a slam system by the way.
