4200psi / 290bar Petrol Pressure Washer

The P4200PWT is a powerful petrol pressure washer from P1 Power Equipment, powered by a 420cc commercial grade petrol engine which drives an Annovi Reverberi (AR) Triplex Pump.

This petrol jet washer produces an adjustable output up to 290 bar or 4200psi with a 15 L/min flow rate, ideal for high-end DIY and light commercial use.

Portable Pressure Washer

This power washer has two puncture-proof tyres which allow it to be moved across rough surfaces easily, making it incredibly portable and easy to move between jobs.

This high pressure washer's large ergonomic soft grip handle bar can be folded for compact storage and the built in rear hose mount protects the hose from the hot exhaust.

Powerful Jet Wash Pump

This power washer uses a high-quality Italian Annovi Reverberi (AR) high pressure pump to give maximum performance and longevity. The expected lifespan of these pumps can exceed 3000 hours* (expected lifespan can vary depending upon the maintenance of the pump).

Annovi Reverberi are one of the world leaders in pressure washer pumps. Annovi Reverberi pumps also feature a detergent outlet for ultimate deep cleaning.

High Pressure Washer

With it's high PSI, this petrol jet washer is ideal for the cleaning of farm machinery, heavy plant, commercial vehicles, skips, wheelie bins, terraces, porches, patios, swimming pools, driveways, patios, windows and more.

Weighing 64kg, the P4200PWT is built using a robust, heavy-duty powder coated tubular steel frame which protects the engine during transportation and use. It also has rubber-mounted anti-vibration feet to reduce noise output whilst you're using it.

P1 Power Washer

This cold water pressure washer can be gravity fed or suction fed, tested up to a height of 2m vertically from a water butt or IBC.

If drawing uphill form a water butt, we suggest you use the following tips:

  • Ensure that the suction hose is 100% sealed against air leaks – any air drawn into the suction side of pump will prevent the machine from priming.
  • Connect the pressure washer to a mains water supply and run for 1 minute to free up any sticking valves.
  • Position the pressure washer as close to the water supply as possible.
  • On startup, to aid priming, prime pump before connecting high pressure hose to pump outlet.

2 Year Warranty

For added peace of mind, this pressure washer is covered by P1 Power Equipment's 2 year home-use warranty* / 1 year commercial warranty* (terms apply), including full parts and service backup to maintain your power washer for years to come.
