Simple product that works phenomenally well
A very simple product that works well! I wish I knew about this years ago because now I only change the soap bottle 1-2 times per year underneath my sink. This works very well, doesn't leak, and I've installed this on 2 sinks now, and bought one for a relative who also loves it. I just buy the big club-sized bottles of detergent now, and avoid messy fill-ups. I can highly recommend this dispenser kit.

Excellent solution for under counter soap dispensers
This is a great solution if you have an under counter soap dispense. No more filling that awkward hard to reach soap container. We attach this hose to an extra large bottle of dish soap and use it for dishes and for washing our hands. The design is great and after almost a year of use it has never failed or clogged. Great value for the money. I would purchase this item again.

Doesn't fit the BIG (1 gal) Dawn container
The product itself works fine, the parts are decent quality & the instructions are mediocre. The problem began when I bought the BIG a$$ Dawn from Sam's Club. The 1 gallon size that comes with a monster pump on it. I thought to myself, "I'll save a little money on the soap, and then I won't have to deal with refilling that irritating little bottle for a lo-o-ong time!" Unfortunately, this kit does not have a stopper big enough for this bottle. I know this without a doubt, because the larger stopper is at the bottom of that full soap jug. So I turned to my trusty gorilla tape & made the bottle opening smaller, then taped in the smaller stopper. It's working, for now. I would have returned it, but that meant dumping out the entire jug of soap to get the stopper out, and cleaning all the soap off of the parts. For $13, this'll do.

IT DOES NOT WORK!
Sorry the pic is a bit blurry, I have some tremor issues and it's hard to take 1 handed pics with my phone. The dishes are for decoration purposes...yeah...decoration... I was hopeful. My dispenser bottle broke after taking it off to do some repairs under the sink (can we get some metal on metal threads for these things faucet makers, or at least the option!? Why pour the soap? Why chance someone pouring too much and overflow it when you put the pump back in and make a mess (...kids...). I'm not some barely functional try and fail at home repairs person (and not implying others are, just context here). I was an aircraft mechanic. I do all our vehicle maintenance for both our vehicles, a 2010 crew cab pickup and a 2017 SUV. I do all of our own home repairs. Electrical (installed ceiling light sin our living room because there were no lights there when we bought the house), drywall, painting, building wooden sheds on the side of the house from scratch, building raised gardens from scratch, replacing plumbing pipes in the wall that developed an 18 inch crack and I'm pretty sure the previous owners ignored for years, you get the idea. I just don't do the super in depth stuff or super labor intensive that only 2 could easily do like HVAC replacement or roofing. I can trouble shoot. I know how things function. So let's get to it. I tried a variety of things to get this to work. I'm not sure how some say it does work. I think, after all the below testing and troubleshooting, that this system only works for a specific type of pump dispenser. If yours looks like the one in the pic, it won't work (see very bottom for my suspicion on why). What did I try? I got the green stopper to fit on the soap bottle. It was tight on. I tried exactly as the instructions state. It wouldn't even feed the soap up the first tube in the bottle. It actually made no progress at all after about 10 minutes of hitting the dispense pump and even picking it up, holding the bottom in my hand, and pumping like mad. I tried sucking it up by mouth (yuck) to where it was an inch from the push dispenser. I hooked it up (it had a snug fit just as the original tube that went into the OG dispenser did). I pumped like mad. Pounded it like I was at an arcade trying to beat the kid that always hangs out playing that game. Didn't feed at all. It actually lost a bit when pumping. "Your check valve was bad then!", you may say. I was inclined to think the same. That'd be my luck. It didn't back feed when I disconnected it and let it hang on its own for a few minutes. So no, the check valve was not the culprit. It functioned on its own when the pump was not being used. I ran a stiff pipe cleaner through my OG pump/dispenser. It's been sitting there, teasing me, for some time. It was clear. No blockage. No dried/caked soap. Maybe the check valve isn't supposed to be hooked with the arrow pointing at the pump? So I tried reversing the tube to where the check valve arrow pointed towards the soap bottle. Still nothing. It ran out of the end, like you'd expect, on the lower end. Maybe it's a pressure thing? The tube doesn't fit in the top of the bottle, in the adapter, tight at all. There is tons of space. I had enough room. So I put the check valve in the correct direction and shoved the bottle end down into the adapter. I made sure the end of the tube was still submerged in soap. I pushed on the bottle to create pressure and make sure it held a tight seal. It held a tight seal and it was hard to push the air out. So, pressure = check. I made sure the soap was right near the pump end. I smashed that button. Nothing. Again, soap actually lost progress in the tube. Hmm, maybe it's too much gravity/weight to overcome the pumping? So I ran the tube up through the second hole on the sink. I put the soap bottle to where it was above the pump handle. The rest of the tube, except the little bit that had to run through the hole in the sink top and under to the bottom of the pump hole, was above the pump itself. I smashed the pump button. Still nothing. Although it didn't lose progress this time at least. Maybe the check valve is too much to overcome? I removed the bottle side from the check valve and fed it directly into the bottle. I then pumped away. Still won't feed. If I had to guess, losing progress during pumping has to do with the pump itself. I think there is a bit of an air release during the down phase of pumping. With the original bottle, this creates back pressure to help push the soap up. This is likely why this system doesn't work. You'd have to remove the entire bottom portion of the pump, which I did try but I couldn't do it without breaking the entire thing. I couldn't get a good grip either and didn't want to cut my hand open trying. To further my suspision of this system, I ran water through the pump itself and held it in my hand when I pumped. There are 2 slots in the black portion of the bottom of the pump that would bubble up a bit when you press down on the pump. I don't know if any other products of this type will work. I'm not going to bother. For the amount I would spend on a second one, or trying more, I could just get a replacement pump setup. DO NOT BUY THIS! IT DOES NOT WORK!

Easy to install-quality product
I have an Allen + Roth faucet from Lowe’s , item # 1023089 and using the included soap dispenser. Lowe’s sells a similar product like this one but the tubing can’t be uncoiled without boiling the tubing in water for 5 minutes. This tubing is very high quality silicone and will NOT try to coil up like others do. I measured the connector and the tube on my soap dispenser before ordering to be sure it would fit. If the tubing doesn’t fit tightly it will allow air into the tube and you’ll have problems getting soap out. I slipped this tubing over the hard plastic tube on my soap dispenser again because I measured before ordering. If it didn’t fit tightly I would have tried a pipe clamp to help tighten it or replaced my dispenser with a known compatible model. I did have to pump it 450 times to get the soap all the way through the tubing but I should have sucked it through. The soap dispenser doesn’t provide much vacuum pressure. I tested it every 12 hours for 4 days and it always works on the 1st pump .this tubing needs to fit tightly onto your dispenser and if it doesn’t it’s your fault for taking bad measurements. I don’t care to see all these 1 star reviews all over Amazon for products that work . These reviewers make it impossible to know what products to buy. I got lucky and just bought this one dispite all the 1 star reviews I read on it.
