Does Sonic reduce water flow?
Sonic is rated for flow rates up to 70 litres per minute - roughly equivalent to around 6 to 8 standard showers running at the same time.
In a typical household, water demand is well below this level, so Sonic won’t restrict normal water flow.
Only in unusually high-flow systems exceeding 70 litres per minute would it become a limiting factor - which isn’t typical in domestic properties.
