Max hose length

<< < (2/2)

Mike Halliday:
I carry 100m on a reel and feel no pressure drop,  but if there is it’s not  noticeable , actually I carry a 35m reel on the trailer unit if I’m using the trailer but it not long enough I connect that onto the van reel so it’s 135m length and still no notice a difference

This seems reasonable.

I see a reduction in flow/pressure at extended hose lengths but I push it.

Up to around 100 metres it doesn't make a noticeable difference - I measure this not in a loss of flow/pressure but in a slow down on how fast I can work.

From 100 - 150 metres you start noticing the difference, above 150 metres an obvious difference, if your using a FSC I would need to go over it twice at least.

On larger commercial there is often no choice than to use these hose lengths, working all the way around a supermarket fire escape walkway, with a standard gated access you cannot get the machine any closer so the hose has to do the work

9 times out of 10 though you can use the supply hose to tank to reduce the amount of HP hose you need, whatever set up you use.

Just done a TK Maxx and a couple of other storefronts in Banbury. From fire hydrant/wash out - 130 metres - HP about the same.

Thank god for the FH. The ice rink left on the carpark was another story at minus 5.

Good luck

Topclean:
Thanks for the info Yada, Mike, so today I hooked up 100m and as Mike posted, no obvious pressure loss, I will add another 100m next week and report my findings, will it make any difference if, for testing reasons the hose is coiled on there reels?

Aqua Power Solutions:
If we are working on a building site we constantly leave the trailer where the water source is to trickle charge the bowser . We run hoses around the building . As long as all your hoses and connectors are serviceable then any flow loss is minimum at the trigger end.

Just be careful at this time of year the ground temperature  can freeze the hoses/connectors & pump
