In normal Ro systems you want the pure water made by the Ro membrane. In a maple sap system your trying to remove as much water as possible before boiling so you reduce your overall boil time for each gallon of pure maple syrup. This housing is a great buy for the price. I fully intend to purchase two more in the near future to add to my system. Be sure to use teflon tape on the threads of the fittings or it will leak. Overall a great ro housing/membrane deal. ## Features - [DIY RO System] What You'll Get: 100 GPD RO Membrane*1, 12" X 2.0" Membrane Housing*1, Wrench*1, Quick Connect Fittings*3.

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 100 GPD RO membrane, at a temperature of 10°C / 50°F (or a pressure of 50 PSI), the GPD Rating is about 50. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H2Z5ZJH | | Best Sellers Rank | #222,238 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,482 in Replacement Under-Sink Water Filters | | Brand | Membrane Solutions | | Brand Name | Membrane Solutions | | Customer Reviews | 4.4 out of 5 stars 242 Reviews | | External Testing Certification | ANSI, NSF | | Global Trade Identification Number | 00850071881936 | | 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 | ROSL1812-100G | | Manufacturer Warranty Description | We provide worry-free service and water purification solutions, welcome to disturb us! | | Material | Polyamide Thin-Film Composite | | Material Type | Polyamide Thin-Film Composite | | Model Number | ROSL1812-100G | | Number of Items | 1 | | Product Benefits | Reduces TDS | | Product Dimensions | 2"D x 2"W x 12"H | | Set Name | 100 GPD RO Membrane Set | | UPC | 850071881936 | | Unit Count | 1 Count | ## Product Details - **External Testing Certification:** ANSI, NSF - **Item Weight:** 14.4 ounces - **Material:** Polyamide Thin-Film Composite - **Product Benefits:** Reduces TDS - **Product Dimensions:** 2"D x 2"W x 12"H ## Images ![Membrane Solutions 100 GPD RO Membrane and 1812 Housing Kit - Image 1](https://m.media-amazon.com/images/I/61VtjUpXuzS.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Does it constantly discharge reject water even when your not using pure water** A: YES, you need to close both outputs or water will discharge from the brine. 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 ### ⭐⭐⭐⭐⭐ Good replacement still testing *by M***L on August 11, 2025* Still testing low cost replacement Ro membrane been using Ro systems for over 40 years started before anybody knew what role was still using the same system one of Apex first customers we won't discuss what I paid for it ### ⭐⭐⭐⭐⭐ Maple sap Ro system. *by C***E on March 19, 2019* I needed an additional Ro housing and filter to increase my sap production.
