View Full Version : 6 Zone Manifold and Valve Box - Fimco Indexing Replacement

I am (finally!!) replacing my 6 zone Fimco Indexing Valve with 6 electical valves. One option is to use two 3-zone manifolds:

___L_L_L____L_L_L

I am not finding a valve box sufficiently large to hold both of the 3-zone manifolds, so I would need two valve boxes.

Another option is to use three cross manifolds with two valves hung off each cross:

---+-+-+

In this option, I have found a valve box that will work, but it is large and fits poorly (i.e., a lot of the space is unused).

Is one or the other better? Suggestions?

Use a 12" standard for three valves, spot a 10" round for the isolation gate valve.

Doesn't always work... depends on the size of his valves. I can barely squeeze 3 1.5" into a jumbo.

Maybe Boots will chime in, he can build a 6 valve manifold that'd fit up a gnats a$$.

True, I was thinking 1" valves, figured Boots would come on with one his stolen pics.

Funny eh? the differences in areas; 1" valves are unusually small in my market, 1.5 more common even for residential.

Smaller valves for city water & then used as a master for an indexing valve.

That is interesting, I've never, except in large commercial sites, used anything more than 1", since I never exceeded 12-15 gpm per zone, even though I've used 1 1/4" mainline pipe in the megas and 1" for the sub-laterals. :waving:

like, what's the backflow preventer, man?

I have an existing back flow preventer. Our regs in our locality would require certified testing (spelled d-o-l-l-a-r-s) if I touch it (or replace it). So I am leaving it alone. It sits a foot above ground level (give or take) and every sprayer for that matter.

I am using 1" valves.

The gnat thing sounds interesting.

Although I've done a few boxes this year that would make you happy :)..


always using a jumbo though.

I like the lack of a cap on the lower manifold on the right; typical Boots install.. :nono:

Because if you don't bring water in, there will be no service problems.

You non-poly guys tend to forget our PVC is hardly poppin' fresh like it is in trenching territory. A single length of one-inch sch 40 is enough for more than a dozen systems worth of manifolds.

I'm with boots on this one...

I've never seen a manifold crack or break here in New England because the glue and primer is a little slopy .

Yeah, just today I was making a manifold a had to dig a piece of PVC from the bottom of the bed of the truck. It was quite dirty I had to wash it before I started glueing.

The big boss loves putting valves, clock, reducer, 2 runs of wire and 4 zone pipes in a tight area about 4 X 8. with barely any running room ..

Thanks to 2 for 1 pulls I can do it..Although im suprised i didn't cut anything

Mike how old are you currently?

He's not telling Ed but there are rumors that he carved the as-builds of his first mega on a stone tablet.

He used a SunDial controller and sched 40 mayans and latins.


It's not the years Ed, it's the miles.

A day older and a day smarter. Just zeroed two RainMaster clocks (90 zones total) and re-initialized for a lower water table on seperate potable/cistern connections with concurrently running and re-charge delay start times. You want to try that at your age? :cool2:

The inspectors here want to see the primer, specially when using potable.

We usually extend it about 1/4" or so outside the coupling and sprinkle it liberally everywhere else for that true Florida look.:p

if you mean the six-in-a box manifold, then yes, it uses a number of the 'nesting' fittings manufactured by Dura

My lateral lines into the zones are CI 200 pipe.

In my manifold I use slip, threaded, slip tees. The valves are connected to the tees with threaded nipples and the tees are glued to each other using pvc pipe.

When I glue the Tees together, should I use schedule 40 or CI 200 PVC pipe? Perhaps it doesn't matter.

Different strokes for different folks, I never use CL class pipe.

Schedule 40 it is!

A union has two components. The male side has a rubber gasket and the female side is a "swivel". When a union is used with a manifold, the purpose is to allow removal of the manifold in order to do maintenance.

Which side of the union should be attached to the manifold - male or female?

CAPT Stream Rotar

Female on the mainifold I would guess..

spinning the valve is eaiser right>?

Its how Dura makes theirs..

I wish I started using more of them...

Eddie is prolly right, but I don't know that it matters, as long as you don't lose the "O" ring.

I took after my boss and started using angle valves, particularly the Hunter PGVs, threaded of course and used 1" x 6" sch.80 nipples cut in half, each valve set with its own Texas Econo box. Id rather pull a single box to fix a valve then to pull a standard or worse yet a jumbo. Ive already had to rebuild two 4 valve manifolds because there was no room when a fitting cracked on a manifold.
