Full Description

240L Pressure Washer Bowser / Buffer Tank, Reliable Supply for High-Output Machines

Connect to mains and feed your pressure washer from a steady buffered reservoir to prevent starvation, cavitation and downtime. Ideal for machines 15 LPM+ (and improves consistency on smaller units too).

240 L Capacity Auto Shut-Off Float HDPE (EN 840) Hozelock® Inlet ½" Male Outlet Wheelie Bin Chassis

Key Features

  • Optimised for High Flow: perfect partner for washers delivering 15 LPM+; enhances reliability on lower-flow units.
  • Automatic Shut-Off: integrated float valve stops overfilling.
  • Mobile Wheelie-Bin Format: robust rubber wheels for easy site moves; lightweight to transport when empty.
  • Quality Connections: Hozelock-style mains inlet; ½" male threaded outlet to your supply line/pump.
  • Built to Last: UV-stable HDPE, compliant with EN 840 for outdoor durability.

Why Use a Buffer Tank?

  • Prevents pump starvation when mains supply can’t match washer demand.
  • Protects pumps by reducing cavitation and air ingestion.
  • Smoother workflow: fewer pauses, faster job completion, lower running costs.

Expert Notes

This 240 litre buffer tank sits between the mains and your pressure washer, giving the pump a steady reservoir so it is not starved when the supply cannot match its demand. That helps prevent cavitation and air getting into the pump, with fewer pauses on the job. It is made for machines of 15 LPM and above and improves consistency on smaller units too. A float valve shuts off the Hozelock-style inlet when the tank is full, and your washer feeds from the ½ inch male outlet. The UV-stable HDPE body meets EN 840 and rides on a wheelie bin chassis with rubber wheels, measuring 103 x 60 x 72 cm. Stand it on level ground before use.

Perfect For / Suitable Surfaces

  • High-flow pressure washers
  • Smaller pressure washers
  • Mobile cleaning setups
  • Sites with a weak mains supply
  • Driveway and exterior cleaning
  • Commercial vehicle washing

Caution: Stand it on level ground, keep the outlet hose short and wide on long runs, and never run your washer once the tank is empty.

How To Use

Setting up

  1. Stand the tank on level ground.
  2. Connect the mains supply to the Hozelock-style inlet.
  3. Run your pressure washer feed from the ½ inch outlet.
  4. Let the tank fill until the float valve shuts off.

In use

  1. Start the washer once the tank has water in it.
  2. Keep the mains running so the tank refills as you work.
  3. Use a short, large-bore outlet hose for very high flow.
  4. Drain it before moving it, as it is lightest when empty.

Top Tip: Keeping the mains connected while you work lets the float valve top the tank up, so the washer does not run short.

Performance Benefits

  • Stops pump starvation
  • Reduces cavitation
  • Fewer pauses on the job
  • Steady flow from the mains
  • Moves around site on wheels
  • Stands up to outdoor use
