Well-Rite WR-120 Well Pressure Storage Tank Steel 33.4 Gal

The Well-Rite WR-120 Well Pressure Tank is a diaphragm type pre-charged hydro-pneumatic tank designed for residential and commercial water well, pressure booster, irrigation and reverse osmosis systems. The unique design of the WR-120 well water storage tank prevents tank corrosion and reduces wear and tear on your well pump. Features: Stainless steel system connection Brass Air Valve with o-ring seal Controlled Action Diaphragm maximizes drawdown Heavy duty butyl diaphragm Appliance quality urethane paint for indoor or outdoor installation Drawdown 30/50 Setting: 11.3 gallons 5 year warranty NSF Standard 61 listed Compatible with the following tanks: Well-X-Trol WX-203 Wel-Flo WF100 Goulds V100 Sta-Rite PSP75T-T03 Sta-Rite PS32-T05 Flex2Pro WWT-35 Champion CH800 How 2 Tank HT32 Sta-Rite PSP32-T05 A.O. Smith SSB-32, PM-32 Flex2Pro H2P-35 Reverse Osmosis Tank Maintenance and Accessories: A tank shut-off valve is necessary to connect the tank to your reverse osmosis system and control the flow of water into and out of the tank. The valve is also essential for performing system service or maintenance. If your RO system uses 1/4" OD tubing to connect to the tank, select the LFPP4VFE4 valve. If your system uses 3/8" OD tubing select the PP6VFE4-MG valve. For optimal performance, it is necessary to keep a pre-charge of approximately 7 psi in your tank. Most automotive tire pressure gauges either do not read below 10 psi, or are not very accurate at pressures this low. 54846 Tank Pressure Gauge reads pressures between 0 and 20 psi, making it perfect for RO tank maintenance. The RO tank should be sanitized before initial use and during every filter change. The Reverse Osmosis Sanitizing Maintenance Kit features Sani-System, an EPA & NSF certified sanitizer, making it a great alternative to using chlorine bleach. The kit also includes a syringe for application of the sanitizer. NOTE: The Well-Rite WR-120 33.4 gallon storage tank can be used for reverse osmosis or well pressure tank applications. The stainless steel connection and fully enclosed polypropylene & butyl water reservoir avoids leaching issues. The air pre-charge is factory set at 38 psi for well tank applications and should be reduced to 7 PSI for RO applications.

Watts FV-4M1-1/2 Automatic Air Vent Valve 1/2"

Watts Series FV-4M1-1/2 Automatic Air Vent Valves provide automatic air venting for hot or cold water distribution systems. These vents purge air that may be in the water system. The vent valve utilizes a float to actuate the valve plug which is located at the top of the valve. Once the air is displaced and the system pressure is sustained, the valve plug seals and prevents any water from escaping from the system. The float vent can also operate as an anti-vacuum device since it will permit air to enter the system when it must be drained. It can also be installed to permit the separation and dispersal of air while fluid is actually circulating in the system. Specifications: Brass body and cover Air vent with silicone rubber seal Float is high temperature resistant polyethylene Suitable for use with glycol systems Can be disassembled for cleaning and inspection Working Pressure Range: 1.45 - 150 psi Temperature Range: 33° - 240° F Disclaimer: Watts® is a registered trademark of Watts Water Technologies, Inc, which is not affiliated or otherwise associated with Fresh Water Systems, Inc. or this site.

Sustainability Score

61%

While the company promotes water conservation through their products, their corporate sustainability practices show room for improvement. They lack transparency in their supply chain and manufacturing processes. Though they have implemented some energy-efficient warehouse practices and recycling programs, they haven't published comprehensive environmental impact reports or clear sustainability goals. Their packaging could be more eco-friendly, and their commitment to reducing carbon emissions isn't clearly documented.
