Old 30 yr old system. Old valves were completely buried, no box or anything. PVB was cracked. New Manifold with 18" of pvc extended from last valve to add the 5 other zones in 2 weeks. (note to the wise guys: I understand I need to do it before winter, I am also aware of the fact that if I do not add them there will be water trapped in the remaining length of the manifold) New PVB with boiler drain New valves (pgv) New Boxes 9 new pgps 10 new 4" (SRS & 1800's) Repaired 3 leaks. Within two weeks, I plan to have the other 5 lines pulled, 5 more valves with manifold (by using an elbow to the existing manifold), New clock, rain sensor, and everything else in place. All original zones are renovated and are working far better than before. Did not have room on the crappy phone for the finished pic's. Will get some tomorrow. Criticism will NOT be allowed. Just Kidding.
