Winterize Sprinkler System Blow Out Adapter: Air Compressor to National Pipe Threads (NPT) Set with Shut Off Valve - Contains all common sizes!

Saving a lot of money having this attachment! Super easy instructions! Great purchase

Been paying >$100 for our landscaper to blow our sprinkler lines for winter. Got this and made up an attachment from the options, and it works like a charm! Already paid for itself, zero leakage and super easy to install and fit for virtually any sprinkler pipe. Awesome, and worth a few bucks more than piecing together the options you’ll find instead.

This came with exactly the attachments I needed. The quality is good and durable.

Works perfectly on the bottom port of the vacuum breaker.

Very good kit. I used multiple pieces to build a universal attachment for my car compressor. Atta hadn’t will universal meet for all pipes, returns, etc… for pool blow out winterizing.

I purchased the Winterize Sprinkler System Blow Out Adapter with high hopes, and it didn’t disappoint! The adapter worked perfectly and seamlessly to support my sprinkler system. It made winterizing quick and easy, providing a secure fit with the air compressor. The set contains all the common sizes, so I didn't have to worry about compatibility. I had trouble finding this in stores, but Amazon came to the rescue with fast delivery. If you're preparing your sprinkler system for winter, this adapter set is a must-have!

I bought this last year, and have now used it twice. It's been fine, even using the small, 6 gallon compressor I have. It just takes a while to charge, and you have to blow each zone multiple times. It literally comes with everything you need to do the job, except a wrench to tighten it up - and if you use enough of the supplied PTFE tape, you probably don't even need that. Sprinkler blowouts where I am are ~$50, so this pays for itself the first time you use it. It takes me about 90 minutes to complete winterization, instead of the 15 or so for someone to do it, but with a decent compressor, it would be the same time..

Short story long, this is going back to Amazon. The kit is a great concept, and maybe works for others, but not for this homeowner/installer. Now, the longer version ... I'm installing a sprinkler irrigation system in a four season, Idaho climate. My valves and manifold are buried underground, and I have a double check backflow preventer valve inside my house, versus a more routine PVB 16" above ground. That said, as I was picking up parts from Amazon and other sources, I noticed this kit and grabbed it. I have a second blow out valve indoors which I had to piece together. This kit definitely saves time. Now the problems: First, this kit has MNPT (male) brass fittings going into FNPT (female) PVC fitting. I just found out that as I was fixing a repeated leak on a house filter, that this is an improper configuration. Between brass and PVC threads, PVC is softer, and brass will win every time. A male PVC fitting can thread into a female brass fitting (don't overtighten)., but a male brass fitting into a female PVC fitting will result in the PVC threads deforming, and the fitting itself can crack. It's prone to leaking no matter how much pipe dope and/or silicon tape you use. "NPT" depends on threads matching and compressing to seal, and again, the female PVC fitting will give out before a proper seal can be made. Second, as configured, the hose will be under continuous water pressure, and will eventually fail, again causing a leak (probably a gusher). Mine would be inside an underground housing, so no UV considerations, but for those who have this thing outside and exposed to the sun, it won't last long. At the very least, you need a primary shut off valve prior to this attachment, which in my opinion, defeats the purpose of putting a shutoff valve on the house. I had considered reversing the hose configuration to place the valve at the other end of the hose, i.e. at the water source, so that the hose would be strictly for air pressure during blow out efforts, but I'd be buying additional fittings to do so. Avoiding that process was why I purchased the kit to begin with. So, I simply purchased a 3/4" PVC (slip/slip) shut off valve (about $5), a 3/4" slip to 1/2" FNPT PVC reducing bushing, and a 1/4" FNPT to 1/2" MNPT Brass adapter bushing from a local big box store. I have a box of 1/4" brass air nipples I picked up from another discount store, and will insert that into the 1/4" FNPT adapter, and we're good to go. (I'd prefer to just order all this from Amazon, but it takes a week to get stuff to me with "Prime", where I live. Can't wait that long.)

This item was exactly as described and quality is good.

Work very well

Works for me
