bellis You will want to begin looking at all vinyl hose to pex connections as they are not secure. Initially I didn't think I had vinyl hose in my Imagine (other than at the pump) where I discovered its hidden behind a panel in the furnace/sink area and connected to a pex fitting under the rig. This past week while camping with some wonderful Grand Design owners in PA, a hose under the floor blew and sure enough, it pulled off the pex fitting. While I do not have an issue with a properly specified vinyl hose, I do have an issue with the vinyl hose clamped onto a pex fitting versus a more aggressive barbed fitting that should be used with vinyl. Rob from Cate & Rob has outlined this extensively so no need to go into great detail.
I pulled the rig to my parents place in Ohio and extended the PEX to above the floor and under the furnace area to install shutoff valves with pex on one side and a barbed fitting on the other to properly attach the vinyl hose.
Anyway, a much needed mod which if the RV industry did this right would not be necessary.
FYI: The vinyl hose that is in my Imagine is specified to operate at up to 150 psi.
