Aqua TecERP-1000 Aquatec AQUATEC-ERP-1000 Permeate Pump, Black

I added a line to my ice maker from my APEC 50gpd RO filter but it wasn't filling the tray fully like straight from tap. Adding this pump and removing the ASO significantly increased pressure and fixed the ice issues. A wonderful side effect is my RO faucet now fills water bottles and other containers 2x faster. I can't speak to reduced waste water but I can believe it, the RO now takes only maybe 30 minutes to regenerate when I draw a lot of water from it.Connection to my RO system was pretty easy, just check out a YouTube video or follow the included instructions. I didn't test for TDS before I added the pump but I do think the levels went up slightly after adding the pump, but that is probably because I disabled the auto shutoff. Still 30ppm from RO vs 400ppm TDS from tap makes a huge difference. I refused to drink our water or ice before I put this in.I did not know there was a quieter version of this pump that worked with 50gpd systems when I ordered, or I would have gotten that. I have sound proofed my cabinet as much as possible but it's still pretty noticeable clicking on and off after you draw water. We only really notice it though when the house is quiet. If TV is on its not a big deal.All in all this is a very worthwhile upgrade to any RO system, especially if you have attached an icemaker.

Works great!Had a tank that I had replaced because I thought there was problems with holding air pressure. The new tank seemed to do better, but I put a little air into the old tank and stored it away. Several months later, their was very little water coming out of the RO faucet. So, I changed out the filters and checked the tank pressure, but no luck, it still didn't improve. I didn't have a way to measure the pressure from the city's line, but it seemed low, so I decided to install this pump as a potential solution.I went ahead and opted to use the pump as the cut off valve and removed the pressure valve that came with the system. Now, even with the city's low pressure, the tank is full, and the output from the RO faucet is great! I was happy withe results of finally have a full tank, vs. the usual half to 2/3 full, that I pulled the old tank out of storage and installed T and added it to the system. Now I have two tanks, both full!Not sure I can say that it actually processes the water any faster, but you can hear it working. It does make a click noise as it works, as others have said, but it's in the kitchen and it doesn't really bother me. I suppose if you were very sensitive about it, you could wrap it in some sort of sound absorbing material, it doesn't have any external moving parts or generate any heat since it just works off of line pressure.Great help to solving my RO problems!

Upgraded to a 100 GPD membrane and needed to swap the permeate pump ERP500 with this ERP1000 to match the 100 GPD membrane. This works well but is noisier than the ERP500. Also changed the flow restrictor to 100/120 GPD to balance the system.

The device works well. As others have said, def has a clicking sound, yet it does not go on forever. Takes a while to first fill and re-fill if you're installing on a new system. After things are up and running, it does not go on too long to get the pressure back to speck. I wrapped the drain line in a foam pipe cover and also mounted the unit to the Apec frame with a bit of foam between and then added a bit more foam between the device and cabinet. All that helps, yet it is not silent, just not as pronounced. Overall, it does what it should, good flow, and the icemaker and fridge work fine. If you have a refrigerator filter, bypass or remove it if you have an auto bypass. You don't need it with the RO system, and it will save $ on buying filters you don't need.

This was a great addition to my RO system!I have Apec RO-90, and have used the pump for 1 year already. Notice that the pump always helps to have higher tank pressure as well as to save water that is rejected. The clicking sound provides a nice comforting indication for when the water is flowing through the system. Actually, when the filters become clogged up, one can hear that the clicking becomes sluggish, and delayed from when the water was poured. So it's a great filter status indicator too! Just listen to the clicking when the filters are new, and then closer to when they need to be replaced. I was puzzled why pumping became delayed in time, and when I pulled out my filters I saw why - they were full of rust! With new filters, it's pumping again right after I pour some water.The slight challenge is how to attach the pump to the RO system. I bought "Big Simple Clip Clamp 2.5" Bracket Reverse Osmosis Ro Membrane Housing" on eBay (3 of these for $3 - see the attached picture), and then M5 -0.8 Nylon Lock Nuts and M5-0.8 x 16 mm machine screws at Home Depot. After drilling a hole in the pump bracket, I screwed together the 2.5" Clamp with the pump bracket, and then snapped it on the carbon after-filter of the RO system (the thin one that sits on top of the RO membrane). The 2.5" clamp is slightly loose, but it holds OK, and will be handy when I pull the RO-90 system out to replace filters.Overall, I saved about $50 on buying the pump separately, vs getting RO-90 with the pump already included. Of course, a bit of handywork was required, and some additional tubes. Notice that RO-90 has plenty of spare length in the provided tubing, so if the system sits near the water source, some of this RO tubing can be cut and used for connecting the pump.

After six months the pump started to leak from the housing. The company never returned my emails.
