Cold Water Pressure Washers

Professional-grade equipment and supplies at Sun Brite Supply — Gaithersburg, MD

Cold water pressure washers handle residential driveways, sidewalks, fences, and lightly soiled surfaces where heated water is not necessary. These units deliver high pressure at lower operating costs than hot water machines.

Ideal for house washing, deck cleaning, and residential flatwork. If you are cleaning commercial concrete with grease or oil, you need a hot water unit instead - cold water alone will not cut through hydrocarbons.

Frequently Asked Questions

When do I need a hot water pressure washer?

Hot water is required for commercial concrete with grease, oil, hydrocarbons, or gum - shopping centers, drive-throughs, dumpster pads, and loading docks. Cold water alone will not break down petroleum-based contamination.

What PSI and GPM do I need?

PSI provides cleaning power while GPM determines how fast you rinse. Most contractors run 3,000-4,000 PSI at 4+ GPM. Higher GPM means faster job completion and more revenue per hour.

Should I choose belt drive or direct drive?

Belt drive pumps run at lower RPM, last longer, and handle 6+ hour daily use. Direct drive costs less upfront but wears faster under heavy commercial workloads.

How do I size a machine for my truck?

Measure your truck bed dimensions and weight capacity. Skid units fit most full-size truck beds. Call us with your truck model and we will match the right unit.

What maintenance does a pressure washer need?

Change pump oil every 50 hours or monthly. Check unloader valve, inlet filter, and hose connections weekly. Replace seal kits at the first sign of leaking - do not wait for complete failure.
