It works well, installs easily but description on Amazon and elsewhere sucks..
on April 11, 2012
I just received and installed this pump. It can be heard while it is working but it's not that annoying. It is filling my tanks (13.2 gallons total) very quickly. I have pressure gauges on the incoming water supply and the tank. It would take forever for a 50 GPD watts system to fill the tanks after it gets past 10 PSI. My TDS is reading 3 ppm higher now and I don't know why. I'll know more as it finishes filling the tanks. my TDS with 0 pressure on the membrane is 9-10 ppm and it's 12-14 now. The tanks are still filling.
It was a surprise to find out the description does not tell you what comes with this system. I was proactive and went out to an actual store to prepare for installing this on a manifold RO. (its different). I received a 3/8" tee, 3/8" line Stop (for plugging one of the ports which is required for adding this pump to a manifold RO), 2 short lines of 1/4" and 2 3/8" x 1/4" connectors for the permeate connections between the RO and the pump. EVERYTHING you need to install this pump is in the kit.
BEWARE: The instructions are from 2004 and not what is on Watts website for installing this pump on a Manifold system. From what I understand, The configuration in the instructions will not work because it would require the finished product to travel backwards through the pump. The most updated instructions are on the Watts Premiere website and it requires plugging one of the ports on the manifold with the included plug and a few inches of 3/8 tubing that you supply.
I tested the output while the tanks are still filling. I got 2 GPM from the RO faucet. I've never seen an RO system with that much pressure before. This is worth it for that alone. One of the drawbacks for me with an RO system is you usually get 1 to 1 - 1/2 GPM at the RO faucet when the tank is full and that usually only lasts for the first gallon. Keep in mind 2 GPM is with the tank at 40psi, it will go higher then that with this pump. The pump turns off when the tank pressure equals the drain line pressure which is usually equal to your incoming water pressure.
This pump brought my tank pressure to 65 psi. (Line pressure is 68 psi). Water output from the RO faucet was 3 GPM. Filled a gallon jug in 20 seconds. I can't expect any better then that, especially for something so inexpensive compared to a booster / delivery pump that requires no power. The only drawback in I wish it was silent, that would be perfection.
I highly recommend this if you are unhappy with your RO's performance / waste water / water usage.
