Why is there slow or no water coming from my Express Water Filtration Systems RO faucet?
- SSara NunezJul 28, 2025
Several factors can cause slow or no water from your RO faucet. If the system is just starting up, it normally takes 2-3 hours to fill the tank; low water pressure and/or temperature can reduce the production rate. Other causes include low air pressure in the water storage tank (add pressure to 8-10 PSI when the tank is empty), a closed tank valve (add a booster pump), low water pressure (make sure tubing is straight), crimps in the tubing (replace filters), clogged prefilters (replace filters), or a fouled RO membrane (replace filters).
