Q:
What does the VIQUA FRSS-20 flow restrictor do?
A:
It limits flow to approximately 20 GPM so the matching UV system receives the contact time assumed for that flow rating.
Q:
Which systems use the VIQUA FRSS-20?
A:
The catalog-approved Fits value lists: FRSS-20, SP410-HO. Match the exact system label and part number before ordering VIQUA FRSS-20.
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.
