My latest project is to remove one entire unused sprinkler valve assembly. Took a bit of care excavating but now I know to cut four pipes and cap at least the inlet (the pipe coming from the bottom of the photo). In a perfect world, I’d remove the three PVC runs into the front yard (mostly native plants there & no lawn!) but that’s a lot of work for no practical good payoff whatsoever. #yardenA trench and excavation revealing three standard Orbit sprinkler valves connected to PVC. One line tees off around the valves, presumably to the backyard valve box. There are two wires coming out of each sprinkler head. The soil is moist with some red coloration. Clearly the soil has experienced moist anoxic conditions.
