VIQUA FRSS-12 Flow Restrictor 12 GPM 1" x 1" FNPT
VIQUA FRSS-12 Flow Restrictor 12 GPM 1" x 1" FNPT
Description
The VIQUA FRSS-12 water flow restrictor is for use with VIQUA Point-of-Entry UV water disinfection systems. The flow restrictor is important because it slows the incoming water flow rate, allowing the UV lamp to effectively treat all water that passes through the chamber. The VIQUA FRSS-12 Flow restrictor makes sure your system does not exceed water flow rate of 12 gpm. For the system to function properly, it is important that the recommended flow rate be maintained.
- Flow Rate: 12 Gallons Per Minute
- 1" x 1" FNPT
- Material: 316L stainless steel
Q:
What does the VIQUA FRSS-12 flow restrictor do?
A:
It limits flow to approximately 12 GPM so the matching UV system receives the contact time assumed for that flow rating.
Q:
Which systems use the VIQUA FRSS-12?
A:
The catalog-approved Fits value lists: FRSS-12, S12Q-PA, SC-320, SP320-HO. Match the exact system label and part number before ordering VIQUA FRSS-12.
Q:
What connection size does this restrictor use?
A:
It uses 1-inch by 1-inch female NPT ports. Match pipe size, thread type, flow direction, and service clearance before ordering.
Q:
Will the restrictor increase household water pressure?
A:
No. It intentionally limits maximum flow and creates pressure drop. Confirm the remaining pressure is acceptable at peak demand.
Q:
Where should it be installed?
A:
Install it in the location and orientation specified by the UV-system manual, following any flow arrow. Provide shutoff and service access and use approved thread sealant.
Q:
Can I choose a higher-GPM restrictor to improve faucet flow?
A:
Only if the UV system and required treatment target permit that flow. A restrictor that allows too much water through can reduce the delivered UV dose.
