I have 2 x 60psi Flowjet pumps in the van.
What can I say, Had them since going wfp 30 months ago.Never had a problem, works every time I turn my hose valve on, the flow rate is allways constant.
If it aint broke dont fix it. So when my pumps go to the great resting place in the sky, I will buy Flowjet again.
But far more important then what pump you use is which Battery you use, But thats another topic.
