My machine is 41 LPM and on idle 25 LPM, never once have I regretted having the larger flow capacity, across all previous machines as well.
The difference is I have an outlet for it and works are very large commercial, rapid and back to back.
Does it have a downside, yes - when not on a WO/hydrant fill and I then have to go and 'fetch' water.
A 1000 litre tank will last no more than half an hour, thankfullly it doesn't run at full flow very often, just when needed.
If you take a 'good' domestic water supply to fill at 15LPM (average), when working full flow there will be a deficit of 12LPM, that eventually becomes downtime, waiting to refill or at least get enough water to carry on and so on and so on.
Pressure washing has the potential to earn great money but it isn't the machine that does that, everyone thinks get a machine and push it out there and here we go.
It just isn't that easy, learn to market the business, blog about it on your socials, get photos and post them, learn to sell it after the enquiry.
Most of all know how to use the machine for the best results, don't settle for 'good enough' match your ability with the machine to 'above' client expectation and that's a standard as minimum.
Domestic market isn't something, pressure washing, I've ever done but target roof cleaning and again do it properly.
When you know what you're doing the confidence on the doorstep will get the sale, a reputation will be built and go from there.
Having the machine doesn't make you better than others, using it to give the best results will do that.
After 16 years I still want to leave the best job possible, looked at a commercial estate yesterday that was staggering in size.
I was going to write something controversial and not for a public forum about 30 LPM boilers - give me a call on that one, through the website and we'll have a chat.

I wish you well on the new venture, like Darran - happy to help if you need it.
Darran - someone else did it while I was everywhere else. We will catch up, if they've done that one over your way I'm sure there'll be others
