I have a PW for my houses and it needs a tank to draw from as most homes will not keep up- (really hard with a well) If you get one stay under 4 GPM if you intend to use just a hose. I have a 55Gal drum that we fill first and draw from that as we keep filling it. That works for about the time till we need to move anyway. As we reset the tank fills all the way back up. We push 8GPM.
