Description
The Low Pressure Switch RO is a small safety switch installed on the feed water line of a pumped RO system. It monitors incoming water pressure. If the supply stops, for example during a water cut or when a rooftop tank runs empty, the switch opens and cuts power to the booster pump. When water returns, it closes and the system restarts automatically.
Without it, a pump can run dry, overheat and fail within a short time.
Why it matters in Oman
Water supply interruptions and empty storage tanks are common in many areas of Muscat and the regions, especially in summer. A Low Pressure Switch RO is inexpensive insurance for your booster pump, which costs much more to replace.
Key features
- Switches off the pump when feed pressure drops
- 1/4 inch push-fit or threaded port
- Spade terminals for 24V wiring
- Compact, mounts inline on the feed tube
- Works with standard RO pumps and solenoid valves

Frequently asked questions
My pump will not start. Is it the switch? Possibly, if feed pressure is very low or the switch has failed. We can test it.
Do non-pumped RO systems need it? No, only pumped systems.
