I have about a 30 year old pool with an inground gunite spa. 4 jets that are basically 1 inch pipes with an orifice about 10 to 12 inches back inside the jets that looks to be about 3/8 to ½ inch. I’m currently remodeling the pool and spa. Are there retro-fit jets that I could install on the 1 inch pipes/jets? Waterway? I’m replastering so I can remove material from around the pipes to accommodate new jets. I can’t really get to the plumbing outside of the spa wall because they heavily coated it with gunite. Should I drill out the existing orifices if I do install new jets? I’m going to run a 2HP shared pump and a 1HP blower on the venturi pipe. Thanks in advance. Bruce
