I have to run a new water supply to the house as the old one has sprung a leak under a 80ft Redwood. It'll have to go under the sidewalk, a low stone wall, mow strip,, and 50ft of ground cover and lawn.
I plan to finally install sprinklers to the front parkway (ivy). There happens to be a hose bib out there that I assume comes off of the old supply line. So, the question is... is it better to run wire out from one of the existing controllers and put a valve out in a box by the street or should I add a valve to the set under the controller and run PVC out to the curd ?
The curb is probably 20-30" below the lawn level, if that matters. The existing sprinkler valves are a 20ft 'L' distance around corner and under mow strip and shrubs from where I expect to connect into the house.
I can think of several pros/cons. But wondered if some issue (anti- siphoning ?) would dictate.
Tnx, Bart
