Was is someone here that posted the picture of their sprinkler system setup with the PCV valve being an entire "take off" type rig they made up?

The in-flow and out-flow water pipes had couplings that allowed the entire PCV valve to be removed, dried out, and stored for winter months.

Going to do this for our neighborhood and want to know what that individual did it.

Thanks

I didn't post it, but I put a ball valve in the pvc pipe before it enters the back flow preventer.

If no one posts a pic, I'll try to take one tonight when I get home if it's not too dark
