    Anyone try these yet (actually don't know if they're available yet.)

    New compact design can go up against a wall. No unions necessary because the whole inner section is removable with a couple screws.


    Took a sample apart at the distributor... looks like good engineering to me.

    R.P.P.s are required within 3 feet of the water meter here for a dedicated landscape meter (office complexes, medical buildings, shopping ceneters, condos, etc.)

    Most guys will use them on single family residences too, just because if you're on a slope it's usually easier and less expensive than running the mainline to the top of a hill... D.C.V.s aren't readily available and generally not used.

    But oddly enough, I come across a lot of DIY installations with A/S valves below grade or even in boxes below grade.

    I'm replacing 12 valves on a job next week were the gardener installed a dozen A/S valves at the bottom of a slope to run a whole backyard. This on a $3.5 M residential property.

    Funny thing is, he didn't realize there was already an R.P.P. protecting the system (hidden behind a hedge).. main problem is the dumping thru the A/S valves of all the water left in the laterals after every run... I think I'll take photos and post 'em. Gnats and mosquitoes seem to love it.
  2. 3.5 mill for a house with some property isn't nothing in our neck of the woods. Heck, 1.3 buys you a 3 bed 2 bath and about 500 sq.ft. of lawn and a non usable hill to boot. :) The house in my signature just sold for 975 in San Bruno.
