Done a little work today, homeowner threaded the blowout plug in too far and broke the PVC elbow. Due to the way the setup was built, I had to cut the entire thing off and rebuild it. No big deal, gave me a chance to fix the other things that needed addressed as well. Set the PVB parallel with the house, installed an iron elbow for the blowout plug. Threaded on both sides, incase it ever needs replaced it can be unscrewed and replaced easily without disturbing the rest of the assembly. Finally, painted her up to make it look nice and protect it a little better from the sun.
Also on this same hacked up system, I will be redoing an entire median of spray heads. Probably 18 sprays, all fed from one end of the median. Great pressure at the start. And at the end they barely pop up. We're going to pull in new lines, staggering the heads and splitting them into two zones to fix the pressure. Currently they are all along the sidewalk, so it should be a real nice improvement for the customer.
They were VERY pleased with the rebuild of the backflow assembly.
