Outdoor Spigot: Okay To Move Underground?
 
I have an outdoor spigot which sits atop an 18" or so piece of pvc. I would like to hide the spigot and was thinking about putting it in an underground irrigation valve box. Is this a reasonable idea?

Thanks

Should work.. Just make sure it has a backflow protector to keep any water from running back into your house water supply.

Is a back flow protector something I could find at my local home improvement store?

Sure can get it local...

Some are screw on to adapt to an existing or you may find a valve for your application already built in. Check the real guy plumbing stores versus the big box. Their expertise its worth it.

Thanks for the info. Along the same lines, since you mentioned the back flow issue, I have a few sprinkler valves located underground in valve boxes. I read that these were supposed to be at least 6" above the highest sprinkler head. Do you know if this is a problem?

Your welcome.

I dont think it would be a problem in season as long as they are backflow protected... Just for drainage when you are winterizing in the fall. But you can blow out the system with air to cure that or put a drain lower in elevation to winterize.

If you just have "in line" valves, there is suppossed to be a siphon break located at the connection betweeen the municipal supply and your sprinkler supply line. If you have individual valves with built in siphon breakers, they should all be located above ground to be functional. Here, it is 12" above the heads.
