Thanks, £20 for trolley, £20 reel which i attached with jubilee clips and i had hose lieing about.

30 psi might work in a backpack but if your van mount with 100m of hose it may struggle because of all the extra friction it needs to overcome.

Wrong sorry, this is how i use mine with 50m on it, and i have used it with 100m.

That's good to hear but if your going to use 100m of hose it sort of defeats the point of a trolley surely?

30psi is fine through 100m of hose we've used it with both 6mm and 8mm hose. Only issues where getting water to flow out at height i.e over that blackspot about 25 footish. PSI actually can work out to metre head and some pumps are quoted as this. Without going through all the jargon you can work out how high a pump can squirt water by its metre head figure (or equivalent PSI). Of course as you point out longer hose runs will mean the pump will have to work a bit harder, but they're still well able for two storeys using the setups we do.

I did all this in college but I can't remember all the calculations involved.
I'm an engineer by trade and I'd always go for the more powerful pump from a reliability stand point.

Yeah you're probably right. We only got to try out the 30PSI ones for WFP because we had got some to supply jet washers and other stuff from our water tanks and then just tried them. We do have one in daily use. We got a pleasant suprise.

yer u need a 100psi imo

[Nathanael Jones]

Too much pressure just puts extra strain on your connections, drains more batter power & can cause hoses to bulge if you use hot water. I have a 100psi pump, but have adjusted the pressure switch down to 60 PSI.

Thanks
Anyone in West Yorkshire got a pump for sale 100 psi preferably?

ive a brand new flo jet but im in Barnsley , where are you in west Yorkshire ?
you could go here if near leeds  airforce

                                                   ls12 1bh
they have both shurflow and flojet pumps in stock . also do 2nd hand pumps , poles,  tanks ect .

How much you want for the pump?
I'm 17 miles away and it's quite a nice drive except for some parts of Darton

Theres 50m on it now...its great to pull trolley up and you can literally get anywhere with it, trolleys can go most places and if it cant i just pull reel off.

I have a twin van mount and this for those awkward jobs.

Your trolley looks both simple and practical, can I ask you where the pump/battery is on the trolley?

Ok, ic, good way to do it, but possibly a bit hard on the back if you are doing it day in day out.
