Review: Title: Great 50 GPD upgrade, but you MUST change your flow restrictor - I purchased this 50 GPD membrane to upgrade and replace the original 24 GPD membrane in my 10+ year old RO system. It’s been installed for a week now and is working perfectly—the water output and tank refill speed are significantly higher than the original specs. ​Important technical tip for upgraders: If you are upgrading from a lower output membrane (like an 18 or 24 GPD) to this 50 GPD version, this is not just a plug-and-play filter swap. You must replace your original waste line flow restriction device to match the greater flow of this membrane. If you run a 50 GPD membrane with a 24 GPD restrictor, you will choke the flow across the membrane surface and foul your new filter very quickly, especially if you are on hard well water. ​Once properly configured with the correct restrictor, this membrane performs exactly as advertised. Highly recommended for breathing new life into an older system.
Review: A Perfect Fit - I would have to have my water tested to respond to the quality of the product, but I can tell you that it fit my Watts Premier Reverse Osmosis water treatment system, model, WP5-50 well, along with the Watts 7 pack of RO replacement filters. I had a plumber install them and he had no problems whatsoever, so that is a saving right there, as they charge by the hour! I was worried they would not fit before I ordered because the manual recorded four different models. I’m a happy camper, so I don’t think I will ever try generic brands in the future!

### ⭐⭐⭐⭐⭐ Still cheaper than Bottled water:)
*by H***S on 29 March 2020*

Overall a good maintenance item and relatively easy to to replace but not simple. System is for a low water use and the water had low TDS but it had been about 6 years since installation. RO filter was discolored but basically the TDS was the same before and after change out. Order TDS meter to check your system. Update for May 2026 Replaced after 3 years. I changed out every component in my 25 year old system because the faucet was constantly gurgling. Changing ASO which did not help. Seems that the RO membranes internal check valve became dislodged and fell out of the housing during replacement. After changing RO membrane and all of the filter it works perfect. About 75% sure it was the internal valve issue but it could have been something else. Just keep in mind that it could be the RO Membrane; however, internet searches never mentioned it as a cause of the gurgling. FYI changing the Membrane every 3 or 4 years is probably a good idea. I Attached photo of small housing with spring and plunger type valve that fell out in case anyone has a similar issue.
