Aquatec 6800 Booster Pump Kit for up to 100 GPD Home RO Reverse Osmosis Water Filter System Standard or Manifold, Includes Pump, Pressure Switch PSW-240, Transformer, 6840-2J03-B224 B221 Made in USA

I purchased the Aquatec 6800 Booster Pump Kit for my 50 GPD 5-Stage Reverse Osmosis system, along with an Electric Shutoff Switch (ESO).Before, my feed pressure into the RO system was between 30 and 40 psi, which wasn't enough to push water into the holding tank. I was constantly running out of water, and it was really frustrating.I tried everything: changing filters, replacing the membrane, and even getting a new backflow valve. But it became clear that the pressure was just too low for the system to run properly. Adding this pump was super easy with the provided instructions. Now, my pressure gauge shows about 60 psi, and I haven’t run out of water since. The water pressure coming out of the spigot is also much higher, making it quick to fill up a pitcher.The Electric Shutoff Switch is a great addition too. It lets the system "rest" between cycles and stops it from continuously wasting water like before. The pump is very quiet, and with the sink cupboard doors shut, I can't hear it at all when it comes on.This has been the perfect fix for my RO system, and my whole family loves the fresh, clean water.

I bought a watts R/O system at Menards a couple years ago and really struggled to get it to work with just house pressure like they said it was supposed to. I called their help line, but got little useful advice. I finally decided to buy this booster pump and the system's been running great since! It pumps at about 90 psi. I connected the R/O water to the cold side of the kitchen sink faucet and bought an extra pressure tank that combined with the other gives about 3-4 gallon of useable capacity. The system recharges in a little over an hour which is above the rate Watts advertises. I'd also recommend you buy a pressure switch that Amazon offers as a "frequently bought with this item".

This small pump was the perfect replacement for my under the counter reverse osmosis system.

I added this booster pump to my home RO system to get more pressure on the inlet, with the ultimate goal of increasing flow rate on the output faucet. It worked in that regard, as do other booster pumps. I tried two different pumps. The benefit of this model is that it has an adjustment screw on the pump to adjust pressure boost and another on the pressure switch that turns it on/off. This is actually the main reason I tried this model, as other models don't always have these adjustment screws. In the end however, I did not end up adjusting, as the default range works in most cases so far. For my level of detail, even if I could adjust things a little, I don't think it wouldn't change much of the desired result. So, the adjustment wasn't a strict need. I read somewhere you aren't supposed to adjust the pump pressure while its running also, which kind of limits the whole trial and error ease of trying different pressures if I wanted to.The actual booster pump worked well. My inlet water pressure was about 40 psi, and when running this pump brought it up to 100psi by default. I installed a guage inline with the pump's output, which is essential. This 100psi was higher than another pump I tried that brought it up to 80psi. I installed a second guage inline right before the tank. This is also essential and honestly the more useful of the guage locations. By default this one reads whatever the tank psi is adjusted to, probably about 7-8 psi steady. Running the booster pump brings this up until the pressure switch turns it off. The most common case is 40/20 where it turns off when it rises to 40 and on again when it falls back to 20. With the booster pump running it slowly rose from 7 psi to 40 psi. This process took about 1 hour, from a "full" 7 psi tank. If you were doing this from no water, obviously longer. The weight of the holding tank noticably increased as it went to 40psi, though I'm not sure how much more water it added. Compared to the other pump that increased inlet to only 80psi, it seemed to get up to 40psi faster.The end result was the faucet flow rate noticably increased, significantly. It is faster when the level is at 40psi than at 20psi. And way better than the 7psi. Living alone, it takes about 2 days to drop from 40-20 psi, and the pump runs just 1hr. I'd rather it was a 30-40psi switch honestly. Or 30-50 I suppose, but I'm not sure if that would damage the tank bladder at that level.Finally, the reason I actually ended up not using this pump was because it was noiser than the other non-adjustable pump I tried. This pump has 4 little rubber feet at the bottom. However it still made a distinct pumping noise when running while the other was near silent. Additionally, the 1/4" water hoses noticably vibrated with this pump, such that anywhere they touched the cabinet wall, tank or one another would make a major rattling noise. I kept trying to carefully place them, but it was never right. I wish this all wasn't the case. There were also no mounting screw locations on the pump if I wanted to try that.

Shipped super fast! Install was very easy (So many videos on YouTube). I've had it now for a few months and OMG what a difference a replacement makes. Will definitely purchse from this seller again.

Quiet, doesn't leak. Bought a 50% cheaper one first but it leaked, this one has been good.

The company has responded and they are sending a part it is still under warranty

Our RO system hadn’t worked well since the delivery people hooked it up to our new refrigerator. They attached the line from the new refrigerator to the old one and it is much longer than it needs to be and with the added length the system couldn’t push the water through fast enough. They did do a good job of leveling it. It fits so snugly into the cabinets that I didn’t want to pull it out to shorten the line. After watching some you tube videos this looked like a good solution. Although when I received it the instructions were different than some of the videos. One guy added a second tank before it worked right which is not necessary if you install it as instructed.At first I thought it made the situation worse, but the next day water was flowing well. Even better than before I got my new refrigerator.At some point I will pull out the refrigerator and shorten the line. That will make it flow really well.I have the pump mounted on the block wall in the basement right under the refrigerator. We can’t even hear it run.Very happy. It’s been about a month. As long as it keeps working, we are very satisfied.
