- Install 1” Apollo PVB backflow preventer device to bring system up to code. - Install inline filter to protect system from possible future issues due to sediment being sucked up from well when it is dry and getting caught in valves, causing them to get stuck open. - Install master valve outside after backflow to contain possible future stuck valves and main line leaks (mostly leaks in manifold as all valves are in boxes right by where main line comes out of house). Master valve inside is not holding and will be bypassed. There is existing extra wire in controller and outside in valve boxes that can be used to power master valve. - Remove wire from Hydrawise master valve terminal that is currently coming from brass master valve, and remove brass master valve and redo copper connection after shutoff valve with piece of 1” copper pipe and 1” pro press couplings *Extensive labor charges to reflect installing new backflow where there currently isn’t one, and not replacing existing backf
