Building 2- piece couplers for Pool and hot tub repair. No cutting or replumbing pipe. Makes that repair quick and easy. In 2019 I broke my union on my Pentair IC-40. I looked, and realized, it was going to be a big job to replace it, and 2 hrs later, my pool guy finished and it was $380.00. I told him that was the last time, we would do that. Next few weeks I figured a way to make a 2-piece, and I found a CAD engineer to help me. In Dec. of 2019, I put my first one on, and it is still on today. In 2021 my union, was voted Most innovative in the Pool Industry, and it has grown from there. I continue making more sizes. I have Patents in the U.S and Canada- selling all over North America, Colombia, and many Islandsl!
