Just out of curiosity what number do you guys have your 100 psi pump at to work on general window cleaning, not cons or fascias.

 We're working as a 2 man wfp set up in an area where water measures around 160 ppm. How does this compare with other areas ? We're in North Nottinghamshire.

There is no right or wrong flow rate the flow setting will be the one that suits you best. You will see flow settings from 30 up through 80 dependant on the individual set up. The ideal is to set the flow to the lowest rate you are happy with,

As for TDS there are plenty of people better than me to answer that one.
