    TDS Meter - Tester. The Only Way To Know If Your Reverse Osmosis RO Membrane Is Performing Correctly - Tests for TDS - Total Dissolved Solids. A Must For All RO System Owners. Compare Incoming Feed Water To Treated Water - Replace Membrane If Less Than 80% of TDS Is Being Removed - The lower the TDS level in the water, the more efficiently your body's cells actually get hydrated by the water that you drink. The higher the TDS levels in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. Simple to use for Reverse Osmosis membrane monitoring. We really like this tester and think that anyone who wants to know about the quality of their water should have one of these TDS Meter Testers to monitor their RO membrane. Learn More

    Protect the bladder of your tank by using our tank inversion stand. Most tanks hold the water in the top portion of the tank instead of the bottom. Storing the water on top of the bladder adds the weight of the water to the pressure to cause unnecessary stress on the bladder. By inverting (turning upside down) it removes the weight of the water on the seal where the bladder is attached to the inside of the tank. Fits most standard 3 and 4 gallon tanks. Plastic Inversion RO Tank Stand. UPC #850901003408 Learn More
