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.
