Approx 20
Based on a recent customer telling me this week that he cleans 3 semis with one of our 35 litre trolleys between refills.
We use 1200 litres on an average full eight hour day per vehicle with a team of three - we dont clean semi's so I cannot give you how many of that type of building.
Our  Average is  50 litres per man per hour so you should acheive five hours on your own with a 250 litre set up.
Our jets are micro pencil jets and we usually restrict the pumps flow but still have very high pressure at the brush due to the small jet.

i would get all day out of that, doing ALL Wfp on domestic

i never use more than 250 L on a domestic day

though saying that, the guy who helped me recently went though allmost 500 L in the day

I work on how much money I earn per tankful.  I have a 300lt 'D' tank which I usually fill to just above the'shoulder'.  This lasts me all day, app £150

If you're carefull it'll last all day.
Personally I'd have run dry by lunch time!!
