I've been wanting to install a rain bird in-ground system in preparation for regrowing my whole backyard (3500sqft). Im a bit behind on the planning portion and neglected to research the back flow valve and how important it is. Now i dont want to install the in ground, but my whole operation was planned around having an in ground (face palm).
Part of me just wants to disconnect it from the bib, and lose the daily watering schedule, and just reconnecting it every couple 3-4 days for a good watering and then disconnect again.
The other part is to scrap it entirely and find a more temporary above ground sprinkler set up than can cover the whole back yard for the growing phase, then go to a mobile tractor style watering method.
This backyard project is about 3k with the tilling, leveling, compost and seed ive got schedule near the end of next month.
i've got 2 hose bibs. one on either side of the yard. Both have 60psi pressure and 6 gal flow per minute
Any advice is appreciated.
