What is your hose setup like? On my WFP setup, I have a 7gpm pump that pulls water from a 200gal tank. It pushes it through ¾in hose to the sediment and carbon filters then the RO and DI filters. It then continues with ¾in hose to a reel where I have to step it down to ⅜in compressor hose like for 100ft, then the last 100ft to the brush os the xero pure line. Before I made that change it was all 200ft of xero 5/16 line so I only had enough pressure on my rinse bar to literally touch the end of the bristles. Now I have water streaming through both the rinse bar and 2 pencil jets with about 2ft of clearance. If you can, run ⅜ line all the way to the pole you should have a significant increase in pressure.
