I've used 600 litre on a single house before :laugh:

But we did learn that as a single operator doing window cleaning full time, you need at least a 400 liter tank. Both boys have 500 liters tanks in their vans which are more than sufficient for a days work

wow that's a lot mate, I carry 350ltr & have never run out on my own although I've come close, now I have my lad with me we use mebbe 450 a day, we only use backpacks so wonder if its to do with flow rate ??

Working with a backpack is slower when working individual houses, but not having to manage hoses is a time saver. My son prefers a backpack so when comparing our setting up, working, refilling his backpack and packing away times, I believe we end up with similar times. And yes, he doesn't use as much water. We do need to scrub and rinse more on coast effected windows than those inland, so do see a big difference in water usage depending on where we are.

But when it comes to commercials, he doesn't even bother with his backpack.

I would think that 400 liters would be the minimum for us now but 500 liters gives them a margin to work with.

yeah I didn't realise you were near the coast, I was trad in Scotland near the coast for a while & noticed the difference.

I've just got my lad a gardiners v3 - I have a v2 - and he had it on full bore fri/sat and seemed to use less water and he was definitely faster

We fitted son's brush with 1mm jets as an experiment. He loves them. It helps him to save water but he also now has enough squirt to blast any bits off the windows. With 2mm jets the flow of water just trickled out.

BTW, I don't like them. He is definitely slower if he plugs that pole into his hose reel doing commercial windows as he doesn't have a fast enough flow to rinse quickly.

doh !! never even thought of taking jet size into account, im off to gardiners site now

cheers

I'm just wondering now if theres something i should do different. I have the tap on my belt so switch water off when moving between windows, i'm not even aiming for a 'curtain of water' when rinsing (like i did when first started). To be fair i have been thinking of getting a digital water meter so i can see how much water im actually using.

You will get a pretty good idea if you aim the jets into a container and let the pump run for a minute. Then measure the amount of water that you have collected. I've done that with my Varistream on a couple of settings.

In reality it will be slightly less at height when scrubbing, but there won't be much in it.

I like the theory of Springs 'new' 2 speed controller operated by remote.

Start off with a slow pump speed for the scrubbing phase and then a click of the remote will speed the pump up for a fast rinse.
