Customers is having a pool installed in the rear of their home. They needed a backflow installed for the pool filler on the left side of the home. I installed a 3/4 watts RP backflow and then removed a 3/4 hose bib on the left side of home. I installed a new Rp back flow strapping to the side of home and installed a new ball value hose bib. It is connected to a 3/4 PVC going to the pull filler.
