Pressure Washers & the Importance of Water

As obvious as it may seem the quantity and quality of the water supply to your wash system is very important.

But when choosing a Pressure Washer for your wash bay, it is essential that you understand flow requirements and where water goes for the successful implementation of your Pressure Washer.

Pressure Washers and Flow of Water

Before choosing your new Industrial Pressure Washer it is essential that you measure the flow rate from your existing water supply.

  1. Take a container of a known capacity i.e a 25 litre drum (We recommend no smaller that a 10 litre drum for best results)
  2. Time how many seconds it takes the container to fill from the fully opened water supply
  3. Divide the number of litres capacity of your container by the number of seconds to fill it and multiply that answer by 60 i.e 25 litres divided by 30 seconds equals 0.833 multiply by 60 equals a flow rate of 50 LPM (litres per minute)
  4. Your measure flow rate should exceed the actual flow rate of your selected Pressure Washer (We recommend about 20%)

How Suitably Protected is your Water Supply

Is the water supply to your wash bay likely to be affected or interrupted by Cold weather? It is no use having a Pressure Washer which is protected from the frost if the water pipes supplying it are liable to freeze!

  1. Try to keep your water pipes inside buildings and minimise exposure to external elements.
  2. Protect exposed pipes using suitable and adequate heat trace and lagging products

Drainage, Waste Water & Discharge

In your vehicle wash bay do you have adequate drainage and do you comply with your local water and environmental agencies when you are handling waste water?

The last thing you want is to invest in a Pressure Washer that your local authority advises you can't use as you don't have the correct infrastructure in place for it.

Speak to your local Authority or Environmental agency to ensure you comply with the laws and local rules.
