120 Litre Mobile Pressure Washer Buffer Tank With Fill Cut Off

The 120 litre buffer tank is designed to ensure your pressure washer is always supplied with the correct volume of water, allowing it to perform as intended. Most standard domestic taps simply do not provide enough flow rate to properly feed professional pressure washers.

For example, if your machine is rated at 12 litres per minute or higher, but your water supply can only deliver 8–10 litres per minute, your machine will never reach its full performance. It can only output what it’s being fed. This not only reduces cleaning efficiency but also means you’re not getting the benefit of the higher flow rate you’ve invested in.

By introducing a buffer tank into your setup, you create a consistent water reserve that allows the machine to draw the full flow rate it requires. This ensures your pressure washer runs at maximum performance at all times, helping you complete jobs faster, more efficiently, and with better results—while also being kinder to the pump and internal components.

The integrated float valve system automatically controls the water level, topping the tank up as required while preventing overfilling. This avoids unnecessary spills and keeps your setup clean and professional on-site.
