SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Todd,

Right I do not need to do the drain. But since the downspout drain is close I figured why not. Less water less mud and weeds. Once I get all the parts, I will take pictures and you experts can let me know how I did if you wish. It is very helpful to have people who do this work professionally who are willing to help the layman.

The drain connection is only required when installing indoors.

If you are installing outside you can drain into the yard.

You are doing your research.

Have a good project.

Todd,

Yes I opened the manuals. Min 12 " above grade. Plus air gap between overflow to drain. Luckily I have a downspout drain right around the corner. So I will dig down to provide a link to that drain. The valves I can place below grade as well as the EZ Flow. I think I have enough room for the three valves and the EZ Flow down in the pit. I am forgoing the mister idea. Oh and thx re the sprinkler valve.

Rainbird dv100.

Sprinkler valve

RP Can not be below grade.

It just can't.

12" above grade.

Thanks

Happy to help.

Todd,

Once again you came through and actually we are on the same plain. I am looking at Rainbird. I have the Drip valves selected. Just checking out the sprinker valve. And I will not put a filter in as you suggest. Water here in San Diego is hard but not dirty. I rarely need to clean any traps or faucet diffusers. So I will be placing my order soon. I wish the area was wider. None of the cover fake rocks will fit unless I trim the back off. I might be able to get everything below ground level if I trench a bit more. Any thoughts re the RPZ being below ground level. Seems to me the design allows for this. So I am not a royal pain I will also do some research on this.

Primary filter for?, the drip kit will come with one.

A filter before the RP Backflow, It will depend on your water supply quality.

In Houston, we normally do not use a primary filter, unless there is a specific known problem with the water.

All drip does need a filter and pressure reduction usually in a drip kit.

Good Luck

I would go with the
Rainbird drip kit.

Rainbird Valves.

They are an industry Standard.

Todd,

Also. How about your choice for valve mfg please. Do you have a particular model in mind?

Thx again.

Tom

Todd,

Thx for the reply. Very helpful. I did make one error. Supply is 1 ". The zone to the slope is 1" , but I know it is reduced to 3/4 on the slope. The back drip is 3/4 right from the valve. The front is 1" . So I will go 3/4 valves for the drip and to keep pressure up on the slope I will go with a 1 " valve. Any thoughts on the primary filter. Do I need it?
