Knowing sprinklers systems are not part of our SOP …
One of my neighbors had a automatic sprinkler system installed at her home last fall. After having a pipe burst last winter at the vacuum breaker, and extremely high water bills this summer, she asked if I would take a look at it. The system is tied both to city water and to a private well. City water side runs directly from the city water meter to the atmospheric vacuum breaker shut off valve at the front exterior of the house then ties in to the well pump output lines in the crawl space and to the sprinkler system zone control valves.
There is no way to winterize the sprinkler riser tree (vacuum breaker / valves) without shutting of the city water to the house.
I have noted repeatedly in homes that I have inspected a shut off valve for the sprinkler system installed inside the house down stream from the main shut off valve.
- Should sprinkler system be tied directly to city water system
- Should sprinkler system be isolated via valve after the house main water shut off valve
- Is there a standard / code that provides detail
your help would be appriciated…
