    This year I'm going to have some jobs where there is no water available and I'm going to use a tank. Last year when I tried a tank it seemed as though the water wasn't leaving the tank fast enough to feed the pressure washer. Should I be running a 12v waterpump off the tank to get water there fast enough? Also I'm charging $50 an hour when I'm running of the customers water. I was thinking of charging about $75 an hour this year and another $25 if I have to use my water tank. Does this sound good? I don't really want to charge alot right now because my machine is only 3000 PSI Landa with a 13 H.P Honda and I'm trying to attain a customer base.

    Make sure you are using a 5/8" hose for the feed and that the connections are air tight. If your pressure washer is a direct drive you'll have to gravity feed from the tank, it won't draw water itself. If its belt driven it will suck the water from the tank in almost any position as long as air isn't getting into the line, but I'd put the outlet valve at the bottom of the tank if it isn't already.

    Not charging much right now to attempt to build a customer base? Think about that for a moment. That is a recipe for a customer base full of un-loyal price shoppers. You are setting yourself up to fail from jump street. People that buy on price will shop anywhere, its a fact. You want LOYAL customers that have paid for your services based on VALUE not price. You should be getting 75/hr no matter what. If you have to drag water there then charge $50 more or something. Usually it just isn't feasible or necessary to haul water around. 99.9% of the time I use the customers water source.

    Vent the tank, did you allow the tank to breath?

    Amazing that this post was just put up, I found it doing a search fir the exact same question. Wanting to use my pressure washer off a tank rather than a pressurized water source. So by gravity feeding from "the bottom" of the tank I am not running any risk of burning out the pump on the pressure washer from lack of initial water pressure?? Are there any ill effects at all to expect?? Thank you everyone in advance for your input.
