Made by Waterway
Gunite Air Injector Grey
Fits inside rigid 1.5" pipe (Actual 41.5cm)
If you are thinking of adding air to your concrete diy hot tub then these should help, they glue into 1.5" plumbing so easy to install after you have tiled your spa.
You will need to plumb a your pipes together through your block or concrete and connect everything at the back, then leave a healthy amount of pipe coming through until after you tile the spa, cut the pipe flush to the surface and then glue these in with UPVC glue.
We recommend Weldon = Please use the correct glue for UPVC fitting to make sure this is permanently sealed.
