Help with water hookup

Hi everyone, I got a possible job, some tire marks on concrete, pretty straight forward. However, the water hookup they have is something I’ve never dealt with before. We are mostly residential and the commercial we’ve done so far have regular spigots; if any of you recognize this hookup and know how I could hook up I’d appreciate the input. Thanks in advance.

Kinda looks like where they hook up a compressor to blow water out of a sprinkler system.

So is not the water hook up? I asked the guy that contacted me and this is what he sent me…

This is how I do it - YouTube

Edit: don’t do it this way

I’ve never seen one of those before, can’t wait to find out what it is. It’s definitely pressurized until a fitting twists in and depresses that valve inside the body. Notice the open ball valve to the right

First of all I can’t believe you made me watch that guy again. He gives me the shadiest vibe (and is our highest ranking Google result in our area). Second of all, altering a waterline on the city side of their backflow preventer is highly illegal. Do not do what he did. Just don’t. Only the water authority is allowed to do what he’s doing in that video, and his $2 PVC backflow preventer on a 300+psi waterline does not protect the municipal water supply. I honestly feel like I should send that video to the NC Water Resource Commission

In my town they have taps on the customer side of the water line. I hate that guy too but only vid I could find on it, had to use it in a couple residential cases when I wasn’t getting enough water flow at the spicket

I hear ya, different rules for different places. In the counties where he operates (Buncombe and Henderson mainly), those backflows are provided and maintained by the municipal water board. Any adjustment, tampering, or alteration of the water system upstream of the BPD (including the BPD) is not legal and carries a pretty massive fine

Sorry if it seems like I’m being aggressive at you, I didn’t mean for that to be the case. That dude just pisses me off, and he’s telling the entire internet to do something illegal. Got me all wound up lol

Bear with me guys, I’ve got one last thing to say about that video and then I swear I’m done. That port that he’s opening is NOT a supply port. It’s used by licensed professionals to test the function of a backflow preventer using a differential pressure guage. There’s a 40-hour course required before you can even TOUCH one of those things

Nicely done! The attachment is in this pic

I might be using it wrong then, I saw that video and got one but it is like the same layout as that one is just past the home owners water meter. Only had to use it twice in about 6 months but I’ll have to look into different options

I’m sure it probably works! But I’m also sure it’s illegal. Again, not tryna salt your game; but hopefully you’ll avoid a fine and an embarrassing business misstep

@Jake_Lambert Is absolutely correct! ! I have 30 yr in plumbing,irrigation and pest control industry’s, Back-flow prevention is a BIG DEAL with big fines. Put the monkey on the property owners back.

Yeap! That’s a Rainbird

There are two different sizes 1/4 and 3/4 iirc

I was kinda close.:+1:

It is an irrigation tap. You need an irrigation key which run about $40 each. No biggie, I connect to them all the time on commercial buildings when a spigot is not available. They are just a regular water line in the irrigation system (tap water usually) for exactly this purpose.

Thanks everyone! Going to get the irrigation key and try that out.

Shut that ball valve before you twist in the key lol
