HI,
I have a 20metre hose coming from my van, which then attaches to my hose cart, this normally means I can set the hose cart on the site I am working at without causing any hazards, just make sure you have a trip hazard sign for when it is on a pathway - you can also get attachments to split your hoses, you could operate from the one hose cart instead of two and split the feed at the end to feed your two poles - hope this helps in someway.
