I Tested And Reviewed 6 Best Air Compressor For Sprinkler Blowout (2023)

I recently purchased the blowout sprinkler and RV plumbing attachment and I must say, it works flawlessly. I used it to blow out my sprinkler systems without any issues, and it also came in handy for draining my RV system for winterizing. This product offers great value for its price and the quality is top-notch.

I have a 900 sqft camp at a river's edge that I close up for the winter due to the rising cost of oil. Previously, I used a homemade setup with a blow valve for cleaning out small parts, but it was messy and time-consuming. However, with this blowout jig and the included blue hose, winterizing has become a breeze.

To prepare for winter, I had already installed two washing machine valves on the hot and cold side, along with separate drain hoses to the ground from the pressure tank and hot water tank in the water closet. The hose adapter came with both male and female garden hose fittings, a 1/4" quick-connect air hose piece, garden hose gaskets, and Teflon tape. These connections can be easily placed on and off on either side of the adapter as needed.

I opted to use washing machine hoses with garden hose on/off valves to have more control and flexibility in directing the air and later the pink anti-freeze. Initially, I gravity-drained the hot water tank and pressure tank, and then connected everything according to the instructions. Setting my air compressor to 40 psi, I attached it to the blow-out adapter using the quick connects, ensuring the valve on the adapter was closed. I slowly opened the air valve on the adapter to avoid any sudden impact of air into the pipes. This feature was a great addition.

After pressurizing the entire system to 40 psi, I proceeded to individually drain the hot water tank, pressure tank, washing machine, dishwasher, sinks (removing the aerators), shower (removing the shower head), toilet tank, and water line to the in-ground well pump. I repeated this process separately on the hot and cold side. It used to take me 3-5 hours, and it was messy. However, with this blowout attachment, it only took me an hour and everything was clean and neat.

To complete the winterizing process, I hooked up an irrigation pump and used the same adapter with the garden hose fittings to pump non-toxic pink anti-freeze through the system. I started by adding a little into the hot water tank and its drain valve, and then repeated the same routine as I did with the air compressor. The pink anti-freeze I used is rated to minus 100°F, which is perfect for the freezing temperatures around here (which can drop to minus 30°F).

I recently had to return a product because it did not fit my specific project requirements. I was attempting to fill a used fire extinguisher, but unfortunately, the product did not meet my needs in this particular case. However, I did have the opportunity to test it out on other items.

One of the standout features of this product is its versatility. The included valves and adapters make it an excellent set for fitting a wide range of valved NPT fittings. In fact, it is estimated that this set can accommodate approximately 95% of valved NPT fittings for different tank sizes. This level of compatibility is truly impressive and ensures that users will be able to find suitable fittings for the majority of their needs.

The ease of use is another positive aspect of this product. The valves and adapters are straightforward to attach and detach, making the set user-friendly even for those with limited experience. This convenience factor is particularly valuable, as it saves time and effort during the installation process.

Additionally, the durability of the product deserves mention. The valves and adapters are made from high-quality materials that are built to last. This ensures that the set will withstand regular use, providing long-term value for the investment.

While the product did not meet my specific requirements, I can confidently say that it is a reliable and versatile option for those in need of valved NPT fittings. Its compatibility, user-friendly design, and durability make it a worthwhile choice for a wide range of projects.

Winterizing your sprinkler system can be a daunting task, especially when you don't want to rely on expensive professionals who may not even show up. Blowing air into the pipes shouldn't be so difficult, but unfortunately, it often is. That's why I'm grateful for the existence of products like the one I found on Amazon.

Initially, I thought I could piece together the necessary parts for a lower price, but that idea quickly faded when I realized the selection of compressors and pipe diameters at my local home improvement store was limited and confusing. To make matters worse, the plumbing section employee dismissed my goal as ridiculous and impossible. It seemed like I was the only person in the world with a sprinkler system!

Finally, I gave in and purchased this kit, and I'm so glad I did. I connected it to a low-cost "hot dog" compressor, and voila! The water blew out of the system like magic. Admittedly, the 5-gallon capacity of the kit was a bit limited compared to more powerful compressors, but with a little finesse, I managed to cycle through all 15 zones in about an hour.

I can't help but think that there is a huge market for a complete unit that seamlessly adapts a compressor to typical irrigation pipe diameters. Whoever creates such a product will undoubtedly become a millionaire. Until then, though, this kit with its stackable parts will continue to serve as a means to achieving your winterizing goals.

One of the reasons I was motivated to purchase this adapter was because I noticed a pattern with the sprinkler guy I hired in the past. Every year, when he blew out my sprinklers for $60, he would miraculously find broken sprinkler heads that I had never noticed throughout the year. He would unscrew them and take them with him, essentially forcing me to call him in the spring to reinstall them and charging me for the replacements.

Frustrated by this experience, I decided to take matters into my own hands and invest in this adapter. With this kit, I can now blow out my sprinklers myself, ensuring that no one can take advantage of me by falsely claiming broken parts. It's as simple as turning the water back on in the spring, without any unnecessary expenses or manipulative tactics.

These two-pack winterization fittings have proven to be incredibly convenient for RV owners and professionals alike. The inclusion of both male and female fittings eliminates the need for switching ends when blowing out a hose, making the winterizing process much easier. The brass construction ensures durability and reliability, with very little chance of anything going wrong.

One satisfied customer, who owns a lawn care company that recently started an irrigation division, found these fittings to be a great addition to their equipment. The flexibility of having both ends came in handy when connecting to irrigation systems, and even allowed them to blow out nearby hoses for customers free of charge. The fittings have held up well during about a dozen blowouts, even with a powerful 210 cfm Kaeser compressor. While they are content with the fittings lasting only one season, they expect them to last several seasons or until they accidentally get left behind.

Another user described the fittings as a simple tool that effectively blows air out of water lines for campers. They found them to work very well, with no issues to report.

Although one reviewer mentioned that the fittings worked as intended, they did experience some difficulty with their compressor maintaining air pressure at 45 PSI to blow out sprinklers. This may be a consideration for those with less powerful compressors.

Finally, a satisfied customer purchased these fittings specifically for winterizing an unused house. They needed a female fitting to screw onto a water hose bib, and these fittings worked perfectly for their needs. They now have the female fitting for the house and a male fitting for future camper use.

I recently purchased the RV winterizing kit and I must say, it has made the winterizing process a breeze. I used it to blow out my water lines and locate a leak in my RV, and it worked exceptionally well. It was much easier than trying to jam the air compressor fitting into the water connection. The valve allowed me to control the air flow while my wife opened and closed the various faucets in the RV. This kit has definitely made winterizing much easier for us.

One of the things I love about this kit is that it allows you to blow out each line individually. This is so much better than running antifreeze through the lines, as it ensures that there is no leftover antifreeze that needs to be cleared out in the spring. I used a small pancake compressor with this kit and went through each line to blow out the water. Now, when spring comes, I can simply hook up the water without any hassle.

Not only is this kit great for winterizing an RV, but it also has other uses. I originally bought it to drain my garden hose before winter storage, but a friend suggested using it on my pressure washer as well. I'm glad I got myself another one because it has proven to be incredibly useful in multiple situations.

The ease of use of this kit is another aspect that impressed me. I previously owned a cheaper nozzle-type winterizing kit, and it was nowhere near as easy to use as this one. With this kit, I was able to blow out my sprinkler system and my camper in no time at all. It saved me a lot of time and effort.

There are a couple of minor drawbacks to this kit. Some users have mentioned that the shut-off valve doesn't seal completely, allowing some air to escape. While it may not serve a significant purpose other than a marketing gimmick, it does slow down the air flow. Additionally, there is no backflow preventer included, although it may not be necessary for a device like this.

Despite these minor drawbacks, I have decided to give this kit a 5-star rating. It is reasonably priced and gets the job done quickly and easily. If you're looking for a reliable and efficient RV winterizing kit, I highly recommend giving this one a try.

The Sprinkler System Air Compressor Blowout Valve is a highly convenient tool for blowing water out of sprinkler systems using an air compressor. With its on/off valve feature, you can easily connect it to a fully charged air compressor and quickly release the air into the system. The inclusion of Teflon tape, although not necessary in my case, is a thoughtful addition.

In my personal experience, I found this tool to be particularly useful for draining water from buried hoses in my garden. It effectively serves as the only method for draining the water, and it performs this task exceptionally well.

I did not receive the Teflon tape or gasket shown in the product photo, but I did not require them for its operation. I have successfully used this blowout valve multiple times to winterize my camper. By adjusting the air pressure before turning it on to the camper, I can complete the winterization process in just 15 minutes, even when taking my time.

Previously, I would utilize a "blowgun" and insert it into the hose with a towel wrapped around it to blow out the water from my water and garden hoses. While this method worked adequately, the Sprinkler System Air Compressor Blowout Valve offers greater control over the amount of air used to push the water out, providing a more effective and efficient solution.
