Any ideas please.
The water coming out of the brush is not a lot more than a trickle. The pump is a shurflo 100 psi, I do use 100 ft microbore but it is no better when I connect brush directly to pump. I have tried another pump and that makes no difference either. The pump is connected to a leisure battery which is apparently charged according to the light on the battery, I have changed the hoses in the van and still no better. I s there a blindingly obvious mistake I have overlooked? Any suggestions welcome
