Air Supply 3 HP Cyclone Pool Line Blower and Vinyl Liner Vacuum 4128100P

I have bottom drains in my pool and while I know some people do not winterize those, I am not taking chances on expensive repairs. The pool installer included the first winterization and he used this blower to fill the drain with air and then closed the valve so the air cannot escape. I tried to do the same with a shop-vac but it did not have the power to blow out the water eight feet deep. This unit did the job in seconds and makes it much easier to blow out all the other lines as well. Totally worth the money.

I just used this to blow out all the lines to my pool. It worked great. I was able to run a hose from the blower into the skimmer and then use the valves on the pool equipment to direct air into each of the pipes that needed to be blown out.This unit has plenty of power for blowing out pool pipes. I understand that some blowers have a hard time blowing out multiple returns at once. You have to wait for one to blow out, plug it, and then the next one starts blowing. This blower pushed the water out of six return outlets at once, and did so evenly.The hardest part is making sure you get the accessories that you need to connect this unit into your system. It comes with an adapter that screws into blower that allows it to connect to a standard 1.5" pool hose. It doesn't come with a hose or anything to attach the hose on the other end to your pool equipment. With this blower I ordered:- a six foot pool hose- 1.5" screw adapter for a pool hose -- same size as the one that comes with the blower, but I'm using this on the other end of the hose to screw into the skimmer. Skimmers usually come with 1.5" or 2" holes and this fits the smaller of the two- 2" screw adapter for a pool hose -- fits the larger size skimmer holes (I have both size, lucky me)If I were doing it again, I would not buy the hose. I have a hose that I could have used (my standard vacuum hose). I bought the extra hose along with some clamps so that I could attach the hose to the adapter more securely and permanently. It turns out that clamping isn't needed. The hose stays on the friction fittings on the adapters while blowing out the lines very securely even without any clamps.With the hose friction fit onto the adapters and the adapters screwed into the skimmers, I was able to blow out the lines alone without any help. I didn't need anybody to hold the hose in place. It stayed right where I put it when I turned the blower on.I also tried to use this blower to blow out a hose line. It is not the right tool for that job. This blower works great for large diameter pool lines, but it fails miserably on 1/2" diameter hose lines. It couldn't push the water through and when I turned off the unit, the water backed up from the line into the blower. I had to dry the blower out completely before I turned it on so that I wouldn't ruin it. I found that an air compressor does a much better job for hose lines.

Seriously amazing little machine. For 30 years I have used air compressors to close my pools and when think of what a pain it was. This plugs in, and does the same job or better in about 10% of the time. No blower or compressor I have ever used worked this well. Yup its big money but it should outlast you,

For years I fought with shop vacs (good ones with 5-6.5HP) to blow out our pool lines and equipment from the skimmer using a Skimmer Winter Tube with Plug. It usually takes 45-60 minutes of fighting to get enough pressure to blow out the lines and sometimes it doesn't work at all. Since this has less Horsepower than the shopvacs I was using, I was skeptical if it would work, but thought I'll try it and return it if it doesn't. IT BLEW OUT EVERY LINE IN OUR POOL IN UNDER 2 MINUTES! That is through the filter, back out to 2 wall returns, out a slide and to three fountains all at once! I wish I bought this 10 years ago.For Reference, I have an in ground pool. I buy the "Skimmer Winter Tube with Plug 17.5" which you have to search for, it has a larger opening in the top than the Gizzmo with plug does, so you can get more air through it. I also bought a PVC reducer to adapt a hose down to fit inside the skimmer winter tube thing and add some duct tape to help it seal. The hose from this pump to the PVC reducer is a "Pentair R211256 Flexible 3 Ft. Vacuum Hose" which I got here on Amazon. (You can also use this hose and a rag/duct tape situation to blow out the lines from the pump, back each direction, but I like doing the whole thing at once from the skimmer on my setup.)I now have a setup that I can winterize my pool 100% in under 10 minutes, including adding chemicals. This is crazy. I'm gaining 3-4 hours per year back!
