This is a DCVA I did today. This house is still in construction.. It was rather funny telling about 25 people today ( 6 different contractors) that I was shutting the water off.. Half were like ohhhh nooooo I need it!! we'll do the installation of the system in like 2 months .

The pipe was 1.5" PEX.. which I've never seen before, has anyone else?
I had the contractor install the 'tee ' point of connection for us.

Why do you use an upside down box under it?

Proper code for a DCVA below ground . The clearance below the back flow assembly is 6". It has nothing to do with drainage or for a relief to spew out( it doesn't have one). Just so dirt doesn't come up and your allowed to test it.

double boxing is so much better.

It looks really clean. I likee. So it's a shallow rectangle upside-down with a jumbo box over the top? At least that's what we call them here.

Looks like Wirsbo PEX to me.
I've used it for drip to pots in patios.
You can heat the stuff up and bend as needed.
It also requires a special tool to spread the tube and collar to accept the fitting.

Nice work on the DCV install.
