The water pressure required for a washer depends on the type of washer and its specific requirements. Typically, there are two common types of washers that people refer to: pressure washers and washing machines.
Pressure Washers: Pressure washers are used for outdoor cleaning tasks such as washing cars, driveways, decks, and other surfaces. The water pressure needed for a pressure washer is measured in pounds per square inch (psi) and gallons per minute (GPM). The required pressure and GPM can vary depending on the type of cleaning job. For light household tasks, a pressure washer with a pressure of around 1,500 to 2,000 psi and a flow rate of 1.2 to 2 GPM can be sufficient. However, for more heavy-duty cleaning, like commercial use, a pressure washer with higher psi and GPM is required.
Washing Machines: For household washing machines, the water pressure requirement is usually lower compared to pressure washers. A standard residential washing machine typically requires water pressure between 20 psi to 120 psi. Most homes have water pressure that falls within this range, so it's generally not a concern.
It's important to note that washers, especially washing machines, come with built-in water inlet valves that can regulate the flow of water and adapt to different water pressures. As long as your home's water supply meets the typical residential water pressure range, your washing machine should function properly.
If you are unsure about the water pressure requirements for a specific washer you have or are planning to purchase, it's always best to consult the manufacturer's manual or specifications for accurate information. Additionally, if you experience any water pressure issues at your home, it's a good idea to have a plumber check your plumbing system to ensure proper water flow to your appliances.
