Spa Remodel - How to plumb

[South_Texas_Sun]

Hi Fig Newton,

Thanks for the reply. She doesn't really need to know what plumbing to add. Everyone seems to agree about that.

Just HOW to bore through the thinnest part (about 12 inches, I think) of the spa wall for a 2 inch PVC pipe? Drill? Chisel? Etc. Her estimates are all over the place, and no one seems to have actually DONE it before. Hence the request.

It's a pool/raised spa combo with plenty of room for plumbing. I'm occupied with work and my own pool project, otherwise I'd probably help her. But I just thought I could get her a little objective advice from one of the pros here.

If your friend wants 8 jets at 15gpm she will need at a minimum 3" suction and 3" return to to feed these jets. To install the plumbing they need to core drill thru the spa wall to install the plumbing. Use a Waterway Plastics Poly Gunite jet body, with this you will have a 2 1/2" pipe coming thru the spa wall. The jets need to be plumbed in a loop to get equal flow.

Thanks for the core drill suggestion, IFN. That's a much better idea than a 2 or 3 inch masonry drill bit.

Only problem is.......with all the helpful suggestions I'm giving her, I may wind up being the one to try to actually DO it....lol

The lowest bid she's gotten so far, for the single suction line alone, is over $1000! I checked out equipment rentals, and it's possible to rent a 3" bit with drill hammer for $160/day.

I think I'm in the wrong business.

Thanks again.
