Air Compressor Quick Connector

[Chevy]

Hi, I'm new here and have been reading for some time now. Lots to learn that's forsure.

Anyways, I would like to winterize my own sprinkler system and I do not know what type of connect I need to attach my compressor hose to the tap. In the past my system has been winterized by the guys that installed the system and I never really paid that much attention to how they connected to the line.

The connector is a normal garden hose tap that they connect the compressor to, and the shut off valve is in the house. What type of connector can I purchase to screw onto the tape with the quick disconnect male on the other end?

Thanks in advance!

I don't think there's a one-piece for this.

I stood in the plumbing section at the local hardware, and put one together out of adapters: quick-connect to fine-thread, fine-thread to hose threads. Took 4 or 5 parts, total.

Screw em all together, there's your adapter.

As the previous respond says, there's no one way. You have to make up an adapter that will work for you. When I blow my system, I remove the backflow preventer. That is attached with 1" copper unions. For the outlet side, I made an adapter that has the mating union half, then reduced the 1" to 1/2" with a ball valve and the quick connect fitting for my air hose. I open one zone at the manifold, then open the ball valve and let it blow until the entire 60 gallon air tank is empty. Then I close the ball valve and recharge the air tank and repeat the process. Then I close the first zone and go to the second. I use 2 tanks of air on each zone. The pros using the big industrial compressors can blow the entire system with one connection, but that costs from $50 and up. It's mucho quicker, but I figure I make pretty good wages doing my own, especially since I already have the compressor.

I blow my daughter's one line with 3 hose bibs with a small compressor through the hose bib at the high end of the line. I use a PVC double female connector with a 3/4" to 1/2" bushing with the quick connect fitting screwed in the other end.

If you ever see the yard service guys going around with the big compressor, you might see that they have a huge collection of fittings so they can make up whatever they need quickly.

the yard fellas lug around a real big compressor behind their trucks for a good reason...

when they connect to your system it literally has so much
PSI and pressure that all the sprinklers literlly jump out of the ground at the same time.....
...

the big compressor kicks butt ,,,,
and thats what you want to do it right.....


how much do they carge you ??

I've been doing my own for several years, but I believe the last time I had it done it was $50. I'm sure it's closer to $100 now. My 7-1/2 HP single stage compressor with a 60 gallon tank is slow by comparison, but my time is mine and since the compressor is sitting in the shop, it just makes sense to spend a couple of hours a year and save the $100. But, you're sure right about those big compressors kicking butt!

Psi and pressure?


Hmmm...


how bout PSI and CFM?

[frenchie]

And actually, you don't need much presssure - my irrigation guy says about 40 psi'll do most zones - it's volume that's important for blowing out irrigation systems.

The conversation started, because I noticed his compressor has no tank. He removed just the actual compressor & carries that around, it's lighter & easier.
