Do You Need Your Own Water for Pressure Washing?
If you’re considering carrying out the best pressure washing service possible , one of the key questions you might ask is; do you need your own water for pressure washing. This article will guide you through the essentials of pressure washing and delve into the water requirements.
What is Pressure Washing?
Pressure washing is the process of using high-pressure water spray to remove dirt, grime, mould, and stains from various surfaces. It’s commonly used for cleaning driveways, patios, decks, and vehicle exteriors. The powerful force of the water not only makes cleaning quicker and more efficient but also helps in restoring surfaces to their original state.
Pressure washing is a popular choice for both residential and commercial cleaning projects. It can save you time and effort compared to traditional scrubbing methods. However, one aspect often overlooked is the water supply necessary for effective pressure washing.
How Much Water Do Pressure Washers Use?
Water usage can vary based on the model and purpose of the pressure washer. Generally, commercial machines typically use between 15 litres per minute (lpm) to 21 lpm. This range is efficient enough to handle most exterior cleaning tasks, ensuring that dirt and stains are removed quickly.
However, some higher-end models—like those from Briggs and Stratton—can consume as much as 30 lpm or more. It’s important to consider that the machine doesn’t constantly operate at its maximum capacity. In many cases, pressure washers are designed with a return-to-tank feature that recycles excess water. This means that while the machine uses a substantial amount of water, it doesn’t necessarily waste it. Instead, the device can reuse water that is not needed for immediate cleaning, significantly reducing overall water consumption.
Average UK Tap Water Supply per Minute
In the UK, the average water pressure for residential areas usually provides between 10 to 15 lpm. However, this can vary based on the specific location and plumbing infrastructure. Older plumbing systems often have narrower pipes due to decades of mineral build-up, which can lead to reduced flow rates.
If you’re relying solely on tap water for your pressure washing needs, it’s crucial to assess your water supply. In some older homes, the water may flow considerably slower. Therefore, if you have a high-demand task like pressure washing, you may need to consider alternative water sources.
UK Standpipe Use
In commercial areas or locations with limited access to reliable water supply, using a standpipe can be an excellent solution. A standpipe is essentially a water supply point that can be connected to a pressure washer. Scottish Water offers standpipe hiring options for both businesses and individuals who require water for specific tasks, such as pressure washing. Pressure washing licencing is not required, but there is best practice and health and safety to adhere to.
These standpipes provide a convenient alternative, especially in urban settings where accessing a tap may be difficult. Hiring a standpipe typically involves obtaining a license and paying for the amount of water used. This option is particularly beneficial for contractors who need an abundant water supply for larger jobs. Failure to apply for the correct licence can lead to prosecution, if caught using a stand pipe illegally.
Additional Considerations
When planning your pressure washing project, consider any local regulations regarding water use. Some UK councils have specific guidelines to prevent waste. For instance, during periods of drought, restrictions on water usage may be implemented. Also, think about the surface material you’re cleaning. Some surfaces might require lower pressure settings or different cleaning solutions. This can affect how long you need to run your pressure washer, thus impacting overall water usage.
