The drawdown for both the stacks and the deep media bed was more than I was comfortable with so a put a Fimco indexing valve in. It is not the low pressure version designed for Aquaponics. My water flow was enough (12gpm) to use the standard irrigation model (Lowes $40). I am currently only using two of the four outlets, The remaining two are capped off but will be used next season when more expansion takes place.

What I thought.  I looked for these a couple of months ago and could only find 1" as well.  I was actually hoping this was a 3/4".  Thanks for the info Ron!  It is much appreciated!

It is 4x 1" line... they also have it in 6x. There is also both 4x and 6x in 1.25".

After three months the only issue I've had is the fish slime buildup causes it not to advance after 5-6 days. I have to remove the cap, blow it out and advance it a few times by hand (all of 5 minutes once a week). Since I need an index valve for my front yard flowerbed, I'll likely get the low-flow and switch them.

Ron - What size PVC is this indexing valve compatible with?  It looks like you're using 3/4" PVC in this picture.
