Title: Big loss of pressure
Post by: petski2 on March 26, 2007, 05:48:23 pm: Hi all,I have a van mount using a 60psi pump.
Iv been using this for 2 years now with no problems :)
I have just swapped my normal half inch hose over to microbore.
The loss of pressure is bloo d y massive ???
By the time the water comes out of the brush its just a trickle ???
There are no blockages or kinks in the hose.
Any ideas what can be done guys or gals.
Thanks
Pete

I get a flow rate of about 2 litres a minute which is good enough for me.

Just make sure the microbore is the one with the clear rubber inner piece as opposed to the thin white plastic inner.

where did you get it from ?

If it is the good 6 mm i might swap it for my 8 mm which i got talked into buying, which i hate , tooo heavy compared to 6mm

I think I may have been using too high a flow rate in the past ::)
What I am calling a trickle is actually about 3 ltrs per minute :o
It may simply be the case that I am over reacting because this new flow rate feels so slow to me.I am used to hearing and feeling the water spray hard onto the glass whereas this just seems to trickle onto it in comparison ::)
I will wait and see what the results are like :)
Thanks for the comments guys :)
