Choosing A Water Blaster 

Lets face it, there are many options when it comes to Water Blasters and pressure washers
Choosing the right Water Blaster is important to ensure what you get is adequate for the tasks you need it for and also to ensure you get the best long term value out of your investment. 
First and probably the most important question is electric or petrol powered.
This is best answered by considering the usual location this will be used in, a contractor who is always at different locations will want petrol, as access to power can be limited, yet a commercial facility that regularly needs to clean its rooms would use electric as it is not going to emit unwanted fumes.
Secondly you should consider the application and whether you require Quality or Quantity - PSI or L/min
PSI is necessary to break the chemical bond between the surface and the stain. The stronger the bond the more you will need to remove it. However if you run your Water Blaster at too high a pressure you will risk damaging the surface.
Litres Per Minute (LPM) is how we measure the flow of water. The greater the L/min the more area you are able to clean.
It is also important to note that water flow is restricted to the flow rate from the tap, for example if you have a 16L/min Water Blaster but only 12L/min from the tap you are not going to have the benefit of the the 16L and will also run the possibility of damaging the pump.
To work out your water pressure fill a 1L bottle, timing how long it takes to fill, divide 60 by the time it takes and this will give you the L/min from the tap. If your water flow is to low you can fill an independent water tank and have the hose continuing to top this up while the Water Blaster draws from it.
