Title: How much water do we use???
Post by: Rob_Mac on June 14, 2012, 03:58:56 pm
Just completed a roof in London and because of the water fill up points being non existent a metered hydrant riser had to be used.

245000 litres of water - we used. I would say a further 30000 litres were also used by others on the same job.

275000 litres of water - at least they have a clean roof!!!!!!!!!!!!

Rob ;D

Hi Rob
 how big was the roof, if 245000 litres of water was used that would have been 245 fills of a 1000 litre container, when using my machine which runs at 21 litres a minute it is usually about 6 fills a day at most as obviously the trigger isnt used all the time with moving pipes etc, have you added another zero there by mistake as by my estimation with that amount of water thats about 40 days work on just the one roof

Hi Rob,
Still have the same water tank that came with the H&M 1350 lts?
The most I ever used when it was running all day (8 hours) was 7 fills with the original pump.
That does seem a lot of water, how many days?

A 21ltr / min m/c would run for 11666.66 mins which is 194 hours  ;) Thats a long day by anyones standards. 16 machines would run for 12 hours and 15 mins without a break

Figures possibly out there

Roger - It now has a 35LPM pump and we have been doing about ten fills per day on the 1350 tank.

Over a 6 day period

13500 x 6 = 81000 litres

There was other people working on the roof as well

So probably 100 000 litres used

Only out by a couple of litres - what's wrong with you all!!!! ;D

Rob ;D
