I second all of Chris’s Questions. Except my xero pure system, minus the pole is exposed to the Central Florida heat and rain as it is mounted on a trailer.
To add:
5. Would using a hose with a larger diameter AND more tensile rigidity (hose which is a little more immune to pressure expansion/swelling) improve pressure at the end of longer runs of hose between the filter and the brush?
**I currently use 200ft of the 5/16 in Xero hose, which is nice for flexibility and attaching straight to the brush through the pole without excess hose when collapsed.
