Residential Pressure Washer: Everything You Need to Know
Residential pressure washers are invaluable tools for cleaning driveways, patios, vehicles, and other surfaces at home. They save time and effort by delivering high-pressure water that effectively removes dirt, grime, and stubborn stains. However, like any mechanical equipment, they may encounter issues that require maintenance or repair. For homeowners in Kenya, Residential Pressure Washer Repair in Nairobi services are essential to keep these machines running smoothly.
How Residential Pressure Washers Work
A residential pressure washer operates by increasing the pressure of water flowing through it, creating a powerful stream for cleaning. Here’s a step-by-step explanation:
- Water Inlet: Connects the pressure washer to a water supply, filtering debris to prevent clogs.
- Motor or Engine: Powers the pump; can be electric or gas-powered.
- Pump: Pressurizes water before it exits through the nozzle.
- Hose and Nozzle: Direct the high-pressure water onto surfaces for cleaning.
Pressure washers typically operate at pressures between 1,500 to 2,000 PSI (pounds per square inch), sufficient for residential cleaning tasks.
Common Problems and Solutions
Pressure washers can face several issues over time. Below are common problems, their causes, and possible solutions:
1. Low or No Pressure

2. Leaking Water
