Can I use a pressurized storage tank with my system?
Yes, your system can be connected to a pressurized storage tank for certain applications. Please contact your dealer for more information
about pressurized storage tank applications. They will provide you with the specific information necessary for this type of application.
Should I be using a storage tank and float switch?
Your VectaMaxx™ RSL system may be wired to a float control shut-off switch that shuts the system off when a non-pressurized storage
tank is filled. Size the tank to provide adequate water storage for your peak demand period. Keep in mind that atmospheric water
storage vessels are subject to contamination by airborne bacteria – they should include a lid, be sanitized before use, and periodically
disinfected. RO product water will have no residual chlorine and will be subject to contamination at all stages in the plumbing system.
Consider UV disinfection as an inline option for all water being pumped from the storage tank into the plumbing system.
An overflow bulkhead with a drain line should be installed in the tank above the float switch water line and be connected to a floor drain
to protect against a failed level control switch. If the inlet bulkhead fitting to the non-pressurized tank is below the maximum water level
in the tank, make sure that a check valve is installed in the product water line between the RO unit’s outlet and the tank inlet. This will
ensure that backpressure from the tank will not damage the membrane(s). To eliminate this problem, install the bulkhead fitting above
the float switch. Float switch contacts should be closed when the tank is empty, and open when the tank is full.
Consult your
Waterite commercial RO systems dealer
for information and availability on a wide variety of water system components
including storage tanks, re-pressurization pumps, bulkheads, tube, pipe, pressure switches, fittings, UV disinfection systems and float
valves.
!
TEST THAT THE PRE-TREATMENT SYSTEM IS DELIVERING RO FEED WATER TO NECESSARY SPECIFICATIONS BEFORE
PLUMBING THE RO SYSTEM ONLINE.
!
ALWAYS ALLOW A NEW SOFTENER INSTALLED TO PRE-TREAT AN RO SYSTEM TO START ON THE BACKWASH/
REGENERATION/RINSE CYCLE. OPERATE THE SOFTENER OFF-LINE UNTIL WATER RUNS CLEAR BEFORE USING IT TO
PROVIDE RO FEED WATER. THIS PROCEDURE ALSO APPLIES TO NEW RESIN BED INSTALLATIONS. COLOUR THROW
FROM NEW RESIN BEDS MAY DAMAGE OR FOUL RO MEMBRANES.
!
WATERITE DOES NOT RECOMMEND THE USE OF A GRANULAR CARBON CARTRIDGE IN THE PRE-TREATMENT
FILTER HOUSINGS SUPPLIED, FOR THE PRIMARY REDUCTION OF CHLORINE. IT WILL REQUIRE REPLACEMENT TOO
OFTEN, LIMIT FLOW RATES AND LIKELY LEAD TO CHLORINE BREAKTHROUGH TO THE MEMBRANE ELEMENT. WE
RECOMMEND THAT THIS HOUSING BE RESERVED FOR 5-MICRON OR 1-MICRON SEDIMENT CARTRIDGES, FOR THE
REDUCTION OF SUSPENDED PARTICULATE.
