Title: What flow rate from brush, as in lpm would be best?
Post by: Pj on January 25, 2007, 09:28:16 pm: I'm sure Reps from water companies don't read this, so you can be honest.

At the moment I use about a cup full an hour ;D but ideally I would like to use about 2litres a minute.

So what flow rate, as in litres per minute do you think would generally work best?

Title: Re: What flow rate from brush, as in lpm would be best?
Post by: Jeff Brimble on January 25, 2007, 10:41:44 pm: PJ I have got used to using about 1/2 litre/min - less in the summer. Phobic spoty windows use the most.

Appologies Matt, thanks, Have you tried less or more or do you find that about right ?

Personally I find it's the right amount for me. I like to rinse a lot and be sure. I have tried with less but found I was chasing bits of dirt down the glass and it took ages.

I have also had it on full power before just to see what it was like. FAR too much!!

What about you? you still on 0.5l a min?

Post by: Pj on January 25, 2007, 10:46:39 pm: Yes. Thanks Chris. I have mine set at about 11

Tomorrow I'm gonna measure what that is putting out in litres per minute.

I am still interested to know what the pros like to use. But they're afraid of who is reading :o

Post by: Alex Gardiner on January 26, 2007, 08:03:46 am: I use 100m of microbore and a 100psi flojet, the flow rate is about 1.5-1.7 litres per minute. Which I find is spot on for my use.

Title: Re: What flow rate from brush, as in lpm would be best?
Post by: Pj on January 26, 2007, 01:24:23 pm: just measured my average flow rate.....2.5 litres per min! :o :o

No complaints from customers though
Title: Re: What flow rate from brush, as in lpm would be best?
Post by: Jeff Brimble on January 26, 2007, 02:07:45 pm: Fascinating 8)
The average is 1.5L/min.
Also depends on the width of the brush ? I use 11" but if you use 15" you would need more water ?
