Draws a lot of water out of the air
582859
Works great,, drops humidity down quickly.

I've got a house I'm remodeling and the crawlspace floods making it very wet, and humid in the house (90% humidity). Once I turn the machine on it drops it down to 60% in a matter of a few hours. You definitely want to hook up the hose attachment, or you'll be emptying a lot of buckets (it fills up fast with all areas of high humidity)

Installed as part of a roof collection system with a first flush diverter (WDDS98) and a Leaf Eater ultra (RHUL98). The output dumps onto the screen on the top of the barrel and all of it flows in, even with gutter-overflowing downpours. I greatly improved mine by ditching that toy of a valve and using a M71QT quarter-turn valve. It now fill watering cans in a few seconds.

Works well and has a nice long range. Be careful how you set it down if it still has water in it (especially uncharged) as mine has a tendency to leak a LOT of water when it's on it's side. I couldn't 5-star it because of the mess it made when setting it down on its side. I would have expected it to be completely contained since it also holds air pressure. Propping it into the upright position solves the leaking issue.

This stream machine holds a lot of water, is well built and shoot a jet of water a far distance.  The kids love it.

This VAC works well, especially for the money. To get all the air out of the hose we have one person in the pool and another holding the hose over the outlet jet of the pump. This will get 80% of the air out. We then work the hose under water and let the bubbles escape from either end. The screen in the canister seems to block a lot of debris and material, but the filter will likely need to be changed after using the vac. Overall we love it.

Our pool, over 20,000 gallons, had set unused for some time.  The frogs were happy with it.  In a smaller more controlled setting where we could have reversed the flow of water, it might have worked better.  I think I had too many leaks.  I am taking the pump off line, using solar, and a floating filter.

WORKS WELL,SPRINKLER SEEMS A LITTLE FLIMSEY,SHOOTS PRETTY FAR COVERING A LARGE AREA

One thing to be aware when using these, suspend it above the cover. Unthinkingly I dropped into the cover and walked away, only to discover that I drained 3000 gal out of my pool.  It removed the bad top water but was drawing good water thru the cover.  Oops.  Great pump.  I recommend it.

I used this for a quadcopter build and while it did what it was supposed to do, the flux is like water and when you press hard on the tip to release the flux, you get a gush of flux that spreads a lot further than intended.
Not a huge problem but a little messy looking.

I have a 4000 GPH pump,  Running this and a small fountain you get a nice bit of performance out of both.  Fountain shoots about 6 feet tall and waterfall spillway over a rock gives a very nice aesthetic effect!

This dehumidifier works extremely well for getting water out of a damp basement.  When the humidity is between 50-55%, I can fill the whole 30 pints in 12 hours.

The reason I gave it a 4 out of 5 is because as other have said, the thing will not shut off unless it is full.  No matter how low the humidity gets, it will endlessly run until it is full.  I ended up actually buying a good hygrometer to go along with this with the same order because of the reviews I read.

If you don't mind this little issue, then it is probably the best deal you can find.

Sometimes too much water comes out at once, but other than that it's great.

Not real pleased with the rate of water that drips out. It does a poor job of slowly watering and lets out way too much water. This created puddles in my flower garden and washed out some of my mulch. I never had any problems like this with the regular rubber soaker hoses.
It is a lot easier to maneuver and lay out. However, I had issues when needing to angle/make a turn. The hose would tend to create a small stream rather than dripping out slowly

This is amazing. It's better than any child sprinkler fun type toy. It shoots water up and spins tons of streams of water around in circles. It's a blast! My only negative is that it shoots really far and there isn't any easy way to control the flow. I live in NYC where backyards are small and neighbors and other people using the yard do not want to be soaked while we're having play time. So, being able to adjust for flow/distance would be a HUGE improvement.

It works well, but does not provide the full flow of the water that is provided to it, which causes a problem for one of my stations that needs a lot of water flow.

This little pump does the job. It is delivering about 180 gpm drawing water up from 17 feet through 3/4 inch pipe in my little garden well. A more powerful pump sucked the water out too fast and lost its prime. When I first tried this pump with a barrel of water, I believe it was pumping a lot more than 180 gpm.  I installed this pump during a dry spell. We got a couple of heavy rains since then, I assume the water table is back up because I'm getting about 240 gallons per hour now. What I wish this had is an on-off switch like my old pump.

I have trouble controlling the output of this sprinkler.  If I turn the water on all the way, it has a very wide spray radius but it tends to water at the circumference with dry spots closer to the sprinkler.  If I turn it to low, it quits turning.  Mainly I use it for the kids to play in.
