Easy Start Technology for Pressure Washer

One of the most frustrating issues with many pressure washers is the engine “lock-up” effect caused by back pressure during startup. That’s why this model includes AR’s Easy Start Valve—a clever addition that momentarily relieves pump pressure when the engine is cranked, reducing resistance and making the machine significantly easier to start.

Benefits of the Easy Start Valve include:

  • Less strain on recoil starters

  • Fewer startup stalls

  • Easier cold-weather operation

  • Reduced wear on your engine over time

It’s a small feature that makes a big difference, especially for users with pull-start machines or older engines.

Brass Head Construction: Built to Endure

The RSV23G33D-F25-EZ features a forged brass pump head, a major upgrade over aluminum and die-cast alternatives. Brass is not only more resistant to corrosion, but it also dissipates heat more efficiently, helping to protect internal seals and extend the life of the pump—even during extended run times.

Whether you’re washing in hot summer conditions or operating at maximum pressure, the brass head provides thermal stability and longevity that can’t be matched by cheaper pumps.

Pump Design and Operation

The design and operation of a high-pressure pump, such as an Annovi Reverberi pump, are crucial to its performance and longevity. These pumps are typically constructed with die-cast bodies and feature brass pump heads, which provide exceptional durability and resistance to corrosion. The inclusion of thick ceramic plungers further enhances the pump’s longevity, ensuring it can withstand the rigors of high-pressure applications.

Annovi Reverberi pumps operate on the principle of positive displacement. This means that the plungers move in and out of the pump head, creating a high-pressure stream of water. The flow rate and pressure of the pump are determined by its size and type, as well as the horsepower of the motor driving it. Designed for optimal performance and durability, Annovi Reverberi pumps are a popular choice for a wide range of high-pressure cleaning applications, from commercial and industrial cleaning to agricultural maintenance.

Frequently Asked Questions about Pressure Washers

How to store a pressure washer?

To ensure the durability of your heavy duty pressure washer:

  • Empty the gas tank to prevent fuel from degrading or clogging the engine.
  • Empty the pump and hoses of any remaining water.
  • Perform necessary maintenance before storage.
  • Store in a dry area.
  • Cover.

What is a pressure washer?

A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.

How does a power washer work?

A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.

Gas vs Electric power washers?

The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.

Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.

Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.

What to consider?

When choosing a gas pressure washer consider:

  • Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
  • Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
  • Engine Power: Bigger engines mean more durability and power.
  • Portability: Weight, handle design and wheel size for easier to move.
  • Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
  • Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.

How much pressure do I need for?

The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:

  • Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
  • Medium duty (patios, fences, decks): 2,000-3,000 PSI.
  • Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.

Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.

Can a pressure washing damage surfaces?

Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.

To prevent damage, consider using a model with adjustable pressure settings.

How to maintain your pressure washer?

To ensure the durability and smooth operation of a pressure washer:

  • Change the oil as per manufacturer’s instructions.
  • Clean or replace the air filter to ensure good airflow.
  • Inspect and clean the nozzle regularly to prevent clogs.
  • Drain the gas tank if you’re storing the washer for a long time.
  • Check the hoses for leaks or damage and replace them if needed.
  • Follow regular maintenance requirements to keep the washer in optimal condition.

Can I use a pressure washer in cold weather and low water temperature?

You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.

Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.
