What is this circled here? Is there a part missing? I turned on my water and this shit started gushing out of of the bottom of the pipe, obviously.

Yes, start digging and when you find the other pipe in the ground, connect them

I don't know shit about sprinkler systems, but I assume that's to provide access to the system.

If you told me "prep the sprinkler for winter" and I didn't know what exactly to do, I'd probably just force compressed air into it to get all the water out.

So I'd need a temporary opening to force air into the system.

Oh look, a separate opening with its own valve to close off, that would let you force air into the system! That looks convenient!

t. I made it the fuck up on the spot



Also, if I were this fictional person responsible for winterizing the system, I might also rub the sprinkler nozzles in grease to keep water from penetrating during the wet months. So maybe check for that too.

Sooo close the valve leading down.

Follow this anon. The backflow preventer is connected inline from the culinary water supply to the sprinkler side supply. There should be a pipe connecting to the open end you circled. If you really get in a bind don't feel bad about calling a company to fix it. You can get an estimate and then if you hire them you can just watch what they do to fix it.

It looks on now and there’s nothing coming out. Did you shut off the water supply? Or did a little just come out and stop? Looks to me like that is just a place to attach a compressor, the pipe to the sprinklers is on the left. If everything is open and the water is on and nothing is leaking I don’t see the problem.

Correct. The main water line is going through the brick behind and just above the circled bit in OP. The backflow is open so if no water is coming out, i assume the valve next to the main is closed and you're good to blow the lines out.



I would still follow that line to double check otherwise your water heater is going to have a bad day.

That is the blowout for winterizing. Close the valve directly above it and it should run to the field as you've already opened that. If water blows out the small metal ball vavle above it close that as well.
