When it comes to pressure washers, one of the key factors to consider is the water flow rate, measured in gallons per minute (GPM). A higher GPM means a more powerful pressure washer, capable of tackling tougher cleaning tasks. But what if you only have access to house water with a limited GPM?

The good news is that most pressure washers can still be run with house water. However, it’s important to note that the GPM of your house water will directly affect the performance of the pressure washer. A pressure washer with a high GPM will be less affected by low GPM house water, while a pressure washer with a low GPM may struggle to perform optimally.

Generally, a pressure washer with a GPM of 1.5 or higher should work well with house water. This is because most houses have a water supply that delivers around 2-4 GPM. So, as long as the pressure washer’s GPM is similar or just slightly higher than your house’s water GPM, you should be able to use it effectively for most cleaning tasks.

However, it’s worth noting that if you have a pressure washer with a high PSI (pounds per square inch), it will require a higher GPM to maximize its performance. In this case, using a pressure washer with house water may not be sufficient. It’s recommended to check the manufacturer’s specifications for your pressure washer to determine the ideal GPM for optimal performance.

In conclusion, while house water GPM may affect the performance of a pressure washer, most pressure washers can still be run with house water with satisfactory results. Just make sure to choose a pressure washer with a GPM that matches or slightly exceeds your house’s water GPM for the best cleaning experience.

Overview of House Water GPM

House water GPM (Gallons Per Minute) refers to the amount of water that flows through a house’s water supply per minute. It is an important factor to consider when determining if the house water supply can run a pressure washer effectively.

The GPM of a house’s water supply depends on several factors, including the size of the house’s water meter, the diameter of the water supply pipes, and the pressure of the water supply. The GPM can vary significantly from house to house.

Most residential homes have a standard water meter size of 5/8 inch, which can provide a maximum flow rate of around 10 GPM. If a house has larger water supply pipes with a diameter of 3/4 inch or 1 inch, the GPM can be increased to 15 GPM or even higher.

The pressure of the house water supply also affects the GPM. The higher the pressure, the higher the GPM. However, too high of a pressure can damage the pressure washer or cause leaks. It is important to check the pressure of the house water supply and adjust it accordingly if necessary.

To determine if the house water GPM is sufficient to run a pressure washer, it is important to consider the GPM requirements of the pressure washer. Most pressure washers require a minimum GPM of 1.8 to 2.5 to operate effectively. If the house water GPM is below this range, it may be necessary to upgrade the water supply system or consider using a different source of water for the pressure washer.

What is GPM and How It Affects Pressure Washer

GPM stands for gallons per minute and it refers to the flow rate of water. It is an important factor to consider when choosing a pressure washer as it directly affects its cleaning power and performance.

The GPM determines how much water the pressure washer can deliver in a minute. A higher GPM means a greater amount of water is being sprayed, resulting in faster and more efficient cleaning. Conversely, a lower GPM means less water is being sprayed, which can result in slower cleaning and less effective results.
