    West coast code still permits it. We call for proper clearance, side to side to test, plus 10" on the vertical with a gravel sump and unions. The new DCVAs with removabable check assemblies may change the specs, but, as a ex- tester, I like all the room I can get.

    Has anyone read the 10th edition of the USC manual yet? From what I heard before it was published, lawn irrigation systems were going to be re-classified as high hazard and DCVAs no longer permitted but I don't have the 10th edition yet.

    Guys, I seriously apologize for my initial sarcasm. The sarcasm does seem a bit thick around here, so I thought it would fit in.

    Thanks to all for the real suggestions. If anyone noticed, the plans are over a year old so obviously I'm in a big hurry to do this.

    Mike, as they say, free advice is worth what you pay for it. Remember, I was starting a discussion:) Seriously, if you ever need dental advice let me know.

    And, the beers are on me if anyone is ever in Winterset visiting the bridges or the Duke.

    Discuss all you like, I'm zipping my lip!!*trucewhiteflag*

    Thanks guys

    I didn't think USC ever recognised DCVA's acceptable for irrigation.

    The purveyor here does not allow DCVA below grade. Must be 12" above grade (they grandfathered in existing). If you have room it really doesn't matter. I would rather look at the top of a VB then a blanket any day.

    Isn't it RP only?

    Not up here, as far as I know. I'll check with Russ, who's certified, but I'm sure he would have told me about any change.

    PVB's are acceptable if they're 12" above the highest outlet.

    Hey don't forget that Rain Bird also offers design service for contractors. I think they claimed 48 hour turn around time. If I recall it was around $55-65 bucks. I had them do a design for my house and it was not to impressive.
