Seaflo 1L Accumulator Tank (SFAT-100-125-01)
Optimized Flow & Extended Pump Life
The Seaflo SFAT-100-125-01 is a high-performance 1.0-liter pressurized accumulator tank engineered for marine, RV, and domestic water systems. By holding a reservoir of air and water downstream from the pump, it acts as a cushion to absorb pressure fluctuations, resulting in a quieter system and a much smoother water flow.

- ✔ Potable Water Safe: NSF/ANSI/CAN 61 certified material.
- ✔ Universal Mounting: Install in any orientation (vertical or horizontal).
- ✔ Quiet Operation: Absorbs pump pulsations and vibration.

Questions & Answers
Is this a genuine original part?
This is a genuine Seaflo manufactured part, built to high industrial standards for reliable performance in harsh environments.
How do I know if it is compatible?
If your current system uses 1/2" NPT or BSP threaded fittings (common in RV and Marine), this tank will fit. It works with all diaphragm pressure pumps.
What pressure should I set the tank to?
For best results, adjust the air pressure in the tank using the tire valve to 2–3 PSI (0.2 Bar) below your water pump's cut-in (start) pressure.
Note: Please verify your plumbing fitting size before purchase. 4boats.co.uk recommends professional installation for pressurized water systems.
