Recommendation for home with 30 psi static water pressure. Very small yard mostly driveways
What's the water supply pipe size? I would guess your best bet would be drip tubing, if it's a really small yard.
its about 25X25 with a U shaped drive way and small strips of grass else where with a decent sized back yard. Sprays or rotors?
Neither, unless you have a booster pump, and you shouldn't have a booster pump, unless you know your supply can give you more water than the booster can pump. (it's a water-safety issue)
What about MP Rotators? Their web site provides performance numbers down to 25psi. I realize it will be pushing the limits, but if you use 1" pipe and keep flow rates low (and if you don't have to use an RPZ).
Edgy...@ 30psi I'd hate to think what operating pressure is @ even 3 or 4 gpm!
use all copper laterals.
Like they say....low pressure equals additional zones.
The[turn your head leary] mp's are a great bet on this project.
You do not need 10 heads per zone.
Bak to plumbing school bub....the friction loss would kill you unless you have
some of Jon's magic pipe...even if you do....have you priced copper lately!
I like MPs. they are a poor man's Stream-Rotor. But 30 psi is getting down
there even if you have zero friction loss, which is impossible. He did not say
if a gpm test was taken, but......shiver.
