Replaced Watts Premier equivalent pump. Uses the same power supply and pressure switch, so I just replaced the pump and kept the power supply and switch for backups.Works fibe so far (days).

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.

This pump works wonderfully. I have had an RO system on every house we have owned since 1998. The last house had good pressure, being on the city water, but now we live where we have our own well. The pressure registers between 26 and 30 psi. Needless to say, that is not enough pressure for an RO system to work efficiently, if it all. This pump not only works well, but the pressure at the tap is greater than it ever was when we were on city water. I highly recommend this pump. And the shutoff works well, too!

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.

A very high quality pump and pressure switch, performs exactly as advertised. I am on well water, and my under-sink 200gpd RO system for my fridge, ice maker, and instant-hot always suffered from low water output, despite a larger 5 gallon pressure tank. I couldn’t get more than 2/3 gallons at time before it lost pressure and the dispenser on my fridge slowed to a dribble. I installed the cutoff switch inline with my pressure tank, and left it at the factory setting of 40psi. As a note my input pressure to the pump is 40-60 psi, and regardless the pump boosted the pressure to 80psi at the RO stage 1 input. I purchased 2 extra $10 gauges so that I can monitor the input pressure and tank pressures. I recommend getting the gauges so you can optimize performance if your system. The pump itself is silent, with a nice vibration-isolating base. Very simple to install with a decent set of included instructions. You may need a couple feet of 1/4 in pex and various connectors to retrofit your existing setup, so order those at the same time (would have saved me a trip to the hardware store).

Nice pump, feels sturdy and well made. Easy to install, quiet, very little vibration with the rubber feet.One nice feature not mentioned in the listing is that the actual pump output pressure is adjustable. (The listing mentions that the pressure switch is adjustable, which is nice, but the pump output is also adjustable).To adjust, you simply turn the 1/16" Allen screw on the top of the pump--right to increase the pressure, left to decrease. I have a pressure gauge right after the pump so I can adjust the pressure going into the RO system--my system is best around 60 - 70 PSI. (See pics)
