  • Terrific solution for draining the pool cover!
Pattern Name: Auto-Siphon Pump
Update: I didn't initially use the included hand pump. It seemed cheap & rinky-dink & was a pain to ttach to the hose to get the flow going. Well, I gave it a try, left it attached to the hose, & now I just squeeze the little bulb until the water starts flowing and the siphon drains the cover, no problem. I leave the pump attached and whenever I need to get the siphon started, it just takes a few squeezes. It's actually terrific. The automated solutions require a long cord attached to an outdoor outlet all the time, and the sump pumps are much heavier and could potentially rip through the cover. This one is light and easy to use. I highly recommend trying this one first. My above-ground pool is 24 feet in diameter; if you have a much bigger pool, or in-ground, where you're pumping uphill, the powered solutions might be a better option. For me, this is perfect. Okay, I didn't try one of the automated pump solutions -- the combination of wires going long-distance to the center of the pool cover to an outlet, the cost, the weight & reliability issues, just wasn't compelling. THIS thing just uses physics to drain the cover and it does an EXCELLENT job... once started. The little toy pump provided isn't impressive & I just used my mouth to get the flow started. So you need to restart it each time you have significant water buildup on the cover. But it's a few seconds and it starts right up and continues until the water has been drained. Sometimes, I have to move it around on the cover to find the deep center of a pool of water, also easy. But it's relatively light, so no cover damage. Siphoning/capillary action WORKS. Earlier, I bought a 1HP sump pump to drain the pool and I had some electrical outlet issues, so I used it as a heavy weight & a passive siphon -- same thing, just started the flow with suction & it drained and entire 24 foot pool without power to the pump until the last few inches! That pump is WAYYY too heavy to put on a pool cover, so this little SwimLine solution is PERFECT! For the price, why not? ... show more

  • Works well.
Pattern Name: Auto-Siphon Pump
Worked better than I was anticipating. That siphon only took 3 pumps and water started flowing. Wish the tubing was longer but they give you an attachment for a hose so it worked out great.

  • Time Saver equals Life Saver!
Pattern Name: Auto-Siphon Pump
This thing works great! We were skeptical at first, but we're sick of bucketing rainwater off of our 10 ft above ground pool cover every other day, so we gave it a try. It was really easy to assemble on the instructions are clear. The unit itself that sits on the pool cover is a little bit larger and heavier than I expected it to be, and that's a good thing because it keeps the pool cover weighted down so that any rainwater sitting on top flows to the lowest point where the siphon begins. It starts working with just a couple of pumps by hand, so you can just set it and forget it! It seems very sturdy and well made. The tubing is stable and there is no leaking, so the siphon function works really well. Each time we've used it we've had close to 50 gallons of water sitting on top of our pool cover from all the rain we've gotten this year and within 30 minutes the siphon has done its job and the pool cover is dry! We've already used it at least four times since it arrived about a week and a half ago ! We also like that it doesn't need batteries or electricity to operate! When it comes time to drain our pool in the fall , I'm pretty sure I can get the last bit of water out of the liner by feeding the siphon tube through the drain hole in our pool and that will be really handy! Highly recommend for small to medium size pool covers!!! ... show more

  • Works quite well, if not in the manner intended by the manufacturer
Pattern Name: Auto-Siphon Pump
I bought this to drain my in ground hot tub cover, about 8 feet in diameter. I quickly noticed that the included hand pump, while operable, leaks air quite badly, rapidly breaking suction on the siphon and causing the drainage to stop. If you aren't willing to modify this a bit, this probably isn’t going to work for you. I also noticed that the head unit, seen in picture 1, is nicely weighted and flat, and because I have somewhat of a height gradient from my in ground hot tub cover to the drain, I thought I had something to work with. I considered returning the whole thing, but didn't want to spend the ~ $150 to buy another powered pump from *ittle *iant, like I purchased to drain my in ground pool cover. I therefore went to the local hardware store and got a drill pump for about $8, as in picture 3 (I already had a drill). I also got their lowest cost garden hose of the desired length, for me 25 feet, which cost about $10. I cut off the appropriate end of the garden hose with a razor knife. Because I already had experience with this type of drill pump, the last one of which failed not because of the pump but because the cheap thermoset plastic housing threads failed after too much "screw on", "screw off", I purchased some quick connects, which are shown in pictures 2 and 3. While these quick connects aren't essential to the running of the siphon, it does make it very convenient to attach the pump to start the siphon, then remove the pump when the siphon is running. It should be noted, as the pictures show, that I have the hose attached directly to the "head unit" with a hose clamp and attach the starter pump to the distal end of the hose with a quick connect. I then remove the drill pump when water flow has started. Pictue 2 shows the siphon in place but not running, but flow is pretty reasonable considering there is a height gradient of less than 1 foot between the hot tub cover and the drain. Obviously if the cover were higher, it would drain faster. The siphon is more than adequate to drain the small area of the hot tub, in spite of the low height gradient involved, even in a relatively heavy rain. What's nice about this setup is that hose distance is relatively unimportant, and there is no motor to burn out if the float switch fails to shut off the pump, as I have observed occasionally with my pool cover pump. I just start the siphon with the drill pump, detach the drill pump, and walk away, letting the siphon run until the cover is empty. The down side is that once the cover is emptied, and the siphon is broken, it won’t restart until I restart it with the drill pump. Discussion: As already stated, the speed of the siphon is a function of the gradient between the reservoir and the drain, so unless there is a large gradient this wouldn’t be appropriate for large volumes or heavy rains. Because my pool cover is below the level of the drain, I continue to use a powered pump to drain it. With those caveats, this solution, as I have modified it, works extremely well, and fits my needs wonderfully. ... show more

  • Easy cover drainage
Pattern Name: Auto-Siphon Pump
Works great. Much easier than trying to siphon with your mouth and getting an occasional mouthful of dirty water. Squeeze bulb appears a little flimsy but will see how long it lasts.

  • Easy to use

If you need a super simple "sump pump" this is perfect, super simple to use, not as fast as a powered pump but get the job done.

  • Game changer – simple and it just works
Pattern Name: Auto-Siphon Pump
I don’t usually write reviews, but this thing deserves one. It’s an absolute game changer. I’ve tried siphoning water off my pool cover in different ways before, and it was always a hassle—messy, inconsistent, and honestly frustrating. With this pump, it’s incredibly simple. A few manual pumps to get it started, and then you just let physics take over. That’s it. No electricity, no complicated setup, no stress. Once it gets going, it does exactly what it’s supposed to do. If you’re tired of dealing with water buildup on your pool cover, just get this. It’s one of those tools that makes you wonder why you didn’t buy it sooner. ... show more

  • Worked once and then it didn’t
Pattern Name: Auto-Siphon Pump
Loved it initially. Used it once w no issue. Drained very slowly but it drained the water from the pool cover. We got a lot of rain again so went out to drain the water again. Today, 2nd use after be packed neatly and carefully away, I set it up and it will not syphon. The part submersed just bubbles and win’t come up the hose. I have youtubed for help, watched manufacturer’s videos, took it apart and put back together and am totally frustrated. Back to looking for another pool cover pump, sadly. Waste of $. I am disappointed and frustrated. However, I’ll try again tomorrow so keep your fingers crossed for me pls! If this is my biggest problem, I am doing ok. ... show more
