Understanding Medium-Pressure Washers: Common Issues and Solutions
Medium-pressure washers are a versatile and popular choice for residential and light commercial cleaning tasks. They provide enough power to tackle dirt, grime, and grease without the excessive force of high-pressure washers, making them ideal for cleaning cars, patios, driveways, and fences. This article delves into how these machines work, the common issues they face, solutions, and the costs associated with repairs, parts, and labor in Nairobi.
If you own a medium-pressure washer, maintaining it is crucial for its efficiency and longevity. For reliable Medium-Pressure Washer Repair in Nairobi, understanding the components and repair requirements can save time and money.
How Medium-Pressure Washers Work
Medium-pressure washers use a motor or engine to pressurize water, which is expelled through a nozzle at high speed to clean surfaces. Here’s a breakdown of how they function:
- Water Intake
Water enters the washer through the inlet and passes through a filter to remove debris that might damage internal components. - Pump
The pump is the core of the pressure washer, pressurizing water to the desired level (typically 2,000–3,000 PSI for medium-pressure washers). - Hose and Spray Gun
The pressurized water is delivered to the surface through a high-pressure hose connected to a spray gun. - Nozzle
The nozzle determines the spray pattern and intensity. Common types include zero-degree (jet), 15-degree (chisel), 25-degree (fan), and 40-degree (gentle wash).
