    Water Depth Below Waterfall from Spa?????

    Sorry I dont have pictures for this but here goes.....

    I'm having a 7.5' spa with a waterfall (18" drop) flowing over into my pool. My concern is this water will be flowing into a very shallow part of my pool, roughly 8-10".

    Is the constant pounding of the water going to hurt the plaster? How deep would it need to be? Would extra steel help strengthen??

    Thanks for your helps/opinions.

    That water will actually be flowing pretty gently and with 8 to 10" of water under it you'll be fine. It won't hurt the plaster.
