Review: COMPLETE GARBAGE & WASTE OF MONEY - DON'T BUY, complete waste of money to spend the extra money on a this new MEMBRANE HOUSING. Upon purchasing i placed it on my system & had absolutely no water. I took the housing off & looked it over to discover that all 3 places where lines go were completely sealed with no way for water to come or go. I would rate this product a ZERO if i could as the quality of this product. Ive ran into the same problem with multipurpose after market membrane housing replacements. I recommend keeping your original membrane housing to your system & just replacing the filter. ## Features - [DIY RO System] What You'll Get: 75 GPD RO Membrane*1, 12" X 2.0" Membrane Housing*1, Wrench*1, Quick Connect Fittings*3.

This membrane is only 0.1nm, 50 times smaller than even the heavy metals. So these RO membranes can easily remove heavy metal, harmful minerals and other soluble salts from water. Enjoy Your Water with Confidence! - [100% Performance and Quality Tested] Membrane Solutions RO membrane uses the most advanced membrane film technology and manufacturing processes, verified by independent laboratory testing. These reverse osmosis membranes are made of the highest quality Polyamide Thin-Film Composite ensures that you get the most filtration and surface area coverage, let you enjoy high-quality taste. - [About RO GPD Ratings] GPD ratings are based on tests performed under specific water conditions (Urban tap water, 25°C / 77°F, 100 PSI). Every time the temperature drops by 1°C / 33.8°F, the GPD Rating drops by about 3-4 %; every time the pressure drops by 1 PSI, the GPD Rating drops by about 1 - 1.5%. For example, a standard 75GPD RO membrane, at a temperature of 10°C / 50°F (or a pressure of 50 PSI), the GPD Rating is about 37.5. - [Tips] Recommend work pressure is 100 psi when using this product in a Maple Syrup reverse osmosis system. And we suggest heating and maintaining the raw sap at 104°F(40°C) to prevent clog on the membrane while keeping it under 113°F(45°C) to avoid damage to the membrane due to over-high temperature. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H31GYTT | | Best Sellers Rank | #282,269 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,777 in Replacement Under-Sink Water Filters | | Brand | Membrane Solutions | | Brand Name | Membrane Solutions | | Customer Reviews | 3.8 out of 5 stars 60 Reviews | | External Testing Certification | ANSI, NSF | | Global Trade Identification Number | 00850071881929 | | Item Dimensions D x W x H | 2"D x 2"W x 12"H | | Item Highlight | Reverse Osmosis Membrane with Housing, MNPT Elbow Fittings, Check Valve and Wrench for Under Sink RO Water Filter DIY, 1 Set | | Item Weight | 14.4 ounces | | Manufacturer | Membrane Solutions | | Manufacturer Part Number | ROSL1812-75G | | Material | Polyamide Thin-Film Composite | | Material Type | Polyamide Thin-Film Composite | | Model Number | ROSL1812-75G | | Number of Items | 1 | | Product Benefits | High rejection rate for lower TDS, standard size for various usages like kitchen, maple syrup DIY, and aquariums.

To stop it from running constantly most use an ASV (Automatic shutoff valve). You will also need a flow restrictor on the Brine, sized appropriately for the RO membrane **Q: what is the wastewater to purified water ratio? can the flow restrictor be bypassed to flush?** A: The purified water to wastewater ratio is 1/2. **Q: Why waste water line seems to be running a lot of water ?** A: Waste water is usually 1gallon RO/DI to 2 to 4 gallons waste. I brought my waste to 1 -2 gallaons of waste to 1 gallon Ro/DI with a booster pump. I also added and upgradeed from 100G to 200Gallon system. Just added another 100G ro/di canister. use the waste water for plants, and garden. If ypu can get waste tube to go out and into a diffrent barrel or yard, you can recycle it. booster pump helps to reduce the waste, unfortunately there is no other way to completely reduce it to zero. good luck. **Q: Can you suggest asov for the 400g system? it has 3/8 input x 1/4 output - all of the asov on amazon are 1/4 x 1/4 or (rare) 3/8/ x 3/8** A: Chemo “Harrington Plastics “ online ## Customer Reviews ### ⭐⭐⭐⭐⭐ It work for the price *by D***N on February 1, 2026* the membrane work as expected. ### ⭐ COMPLETE GARBAGE & WASTE OF MONEY *by V***G on October 14, 2025* DON'T BUY, complete waste of money to spend the extra money on a this new MEMBRANE HOUSING.

Otherwise, this is a nicely made RO membrane and housing that I used to convert a 3 stage filter into a classic RO filter after the manufacturer (Express Water) told me it couldn't be done. ## Frequently Bought Together - Membrane Solutions 75 GPD RO Membrane, Reverse Osmosis Membrane with Membrane Housing, Wrench, 1/4" Quick-Connect Fittings, Check Valve, Replacement for Under Sink Home Drinking RO Water Filter System - Membrane Solutions T33 Inline Water Filter, 1/4" Quick-Connect Filter Replacement Cartridge In-line Filter for Refrigerator & Ice Maker, Post-Carbon Filter for Reverse Osmosis Water System, 2-Pack - Malida 1/4 inch O.D.
