Frequently Asked Questions

What are the Top Brands of Pressure Washers?

At PowerWash.com, we prioritize the performance and dependability of the engine and pump over brand names. Our dedication lies in providing our customers with top-notch pressure washers that deliver exceptional results. We understand that brand loyalty can sometimes overshadow the true value and functionality of a product, which is why we meticulously curate our recommendations based on performance, reliability, and overall user experience.

Which is More Crucial, GPM or PSI?

The importance of GPM (flow) vs. PSI (pressure) depends on the cleaning task. Generally, prioritize GPM for larger areas and PSI for stubborn dirt, while considering the surface’s recommended pressure ratings.

Why is Correct Nozzle Sizing Crucial for GPM and PSI?

Proper nozzle sizing ensures safe and efficient operation, especially when changing the pump’s specifications.

What Causes My Pressure Washer to Smoke?

White smoke is usually residual oil burning off and is not harmful. Persistent smoking or black smoke indicates a potential issue that needs further investigation.

How to Replace a Pressure Washer Plug?

To replace the oil plug:

  • Unscrew the sealed plug shipped with the washer.
  • Replace it with the vented plug provided.
  • Clean any oil from parts like the air filter or spark plug if necessary.
What Type of Oil is Suitable for My Pressure Washer?

Use non-detergent, non-foaming oil for the pump, and refer to the owner’s manual for the correct engine oil, typically SAE 10W-30 or a suitable alternative based on operating temperature.

How Often Should I Change the Oil in My Pressure Washer?

Change the engine oil after the first 20 hours or 1 month of use, then every 6 months or 100 hours. Change the pump oil after the first 50 hours, then every 100 hours or 3 months.
