|---|---|
| Should I choose a hot water or cold water pressure washer? | Cold water units are great for removing dirt, grime, and mud. Hot water is essential for cutting through grease, oil, and other tough, sticky substances, making it ideal for commercial and industrial cleaning. |
| What is the difference between a belt drive and a direct drive pump? | Direct drive pumps are connected directly to the engine and run at a high RPM, making them compact and economical. Belt drive pumps use pulleys to run at a lower RPM, which reduces heat and wear for a longer service life, ideal for heavy daily use. |
| Which is more important for cleaning: PSI or GPM? | Both are crucial, but GPM (gallons per minute) determines your cleaning speed and rinsing power. PSI (pounds per square inch) provides the force to break contaminants loose. A good balance is key for professional results. |
| Do I need a buffer tank to feed my pressure washer? | Yes, you should always feed a professional pressure washer from a buffer tank, not directly from a spigot. This prevents the pump from being starved of water (cavitation), which can cause serious damage, especially to belt-drive units. |
| What does the unloader valve do? | The unloader valve is a safety feature that redirects water flow back to the pump inlet (in bypass) when you release the trigger gun. This prevents pressure from building up to dangerous levels and protects the pump from damage. |
| How do I winterize my pressure washer to prevent freeze damage? | To winterize, flush all water from the system, including the pump, hoses, gun, and any accessories. Then, circulate a pump-safe antifreeze through the system until it comes out of the discharge end, ensuring all components are protected. |
| Can I use any kind of soap in my pressure washer? | No, only use detergents specifically designed for pressure washers. Household soaps can damage internal components like seals and o-rings and may not be environmentally safe for runoff. |
| How often should I change the oil in my pump and engine? | Follow the manufacturer's recommendations, but a general rule is to change the engine oil after the first 20-30 hours of use and every 100 hours thereafter. Pump oil should typically be changed every 250-500 hours of operation. |
