In Use

Stored after flipping upside down to remove some water.

The inline blue one at the faucet with the pressure guage I just set on top of my totes against the wall. There is a camp chair laying in front of it stored so it stays in place.
Never have worried about the ends. Clear the faucet of rust as stated in the previous post then just run a bit of water through to get rid of any air. Figure that cleans it out good enough.
Actually have a second blue filter before these filter and after a water softener with maybe a three foot hose. That one I just loop around end to end, connect them and store it that way. Reason for that filter is just in case the media in the softener escapes.
Everything is quick disconnects except the faucet end.
All the hoses are stored in my hitch cargo basket in a canvas tote. Just blow out my hoses with a small leaf blower.
