Watts Premier ERP-1000 Permeate Pump Installation Kit for 4-Stage or 5-Stage Unit RO Reverse Osmosis Systems, 1/4" and 3/8" Adapters, Easy Retrofit, No Electricity Required

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.Update: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.

This is the fourth of these pumps that I have used for 4 RO units installed in 3 different houses.The pump is easily the best improvement for an RO system. The pump uses the brine from the RO process to briefly and intermittently isolate the membrane output and pump collected permeate (water that has passed through the RO membrane) into the holding tank and to the tap. On the backstroke, the pump reduces back pressure on the membrane and pumps the brine into the air gap and drain.This improves the efficiency of the RO process. Result: higher pressure and greater flow at the tap, shorter refill times, reduced brine waste, a fuller holding tank and reduced noise from the air gap. The pumps come with good instructions, push fittings, etc., and are relatively easy to install.

I installed the pump with my WP-5 system. Instructions are easy to follow, I like the diagram since it is very straightforward. When the pump is working there is a clicking noise coming from it every 2 seconds also. But it is not too bad because it is only noticeable when I am in the kitchen. Filling the tank seems to be quicker than without the pump. the included tube fittings are of good solid quality.

I installed the Watts 5-stage manifold RO system with the booster pump for my parents. The system works great and has plenty of pressure for the fridge icemaker and faucet, and recovery rate is super fast compared to no booster pump. However, my parents complained that the darn thing wastes so much water in the process. I added the permeate pump (keeping the booster pump) and amazingly water consumption is reduced by at least 5x, if not more.The permeate pump is purely mechanical and generates quite a bit of racket and vibration. I found it was easier to mount it on a solid piece of wood. Depending on how you installed the RO system, the included tubings may not be long enough.Well worth the price.

Got this pump for my water purifier because I am on a well with a 30-50# differential. So. sometimes the water pressure is down to 30 pounds, before the well pump comes on.I installed it with an Apec RO-HI reverse osmosis system. The diagrams are good, but you will have to read carefully and pay attention.

honestly you dont need an installation kit if you already have some leftover 1/4" tubings and the RO system is using 1/4" tubeworks. It works great with ispring rcc7 70GDP, installation is easy (just follow ispring or the included guide). It cuts me pure water to waste water ratio from 1:4 to 1:1.5, yes it clicks but unnoticeable unless you are near kitchen.

Came with all the fittings needed to install.

Like it ability to save water...since we are on a septic system. I've read complaints of this being noisy...❓..to stop this...I have taped the discharge hose to under part of sink...wa-la..silent.

Great product. Increased flow from R/O to fridge. Happy now

I added this pump to my existing APEC RO -90 system because of my low water pressure (30-50 psi). The pump came with clear instructions and was very simple and easy to install. It completely fixed the low pressure problem and now the RO unit works perfectly.
