I want to get water from the first floor up along the outside of the wall (with a parapet and projecting coping) to the second floor.
I got this working as follows: 1st floor hose bibb -> 4:1 hose adapter -> Garden hose-mpt adapter->mpt-sharkbite 90 degree elbow -> 14 foot run of 1/2" PEX that goes through a 45 degree curve (now vertical), and then goes in rounded manner over the parapet wall (supported only at the top, and over to a Sharkbite->MPT(Female) ->hose bibb attached to the deck railing.
Works fine, but PEX degrades in sunlight, so this isn't a long-term solution. I'm concerned that the copper is heavier than the PEX and will put a lot of weight on the 4-1 hose adapter, and since the pipe is 6+ inches off the wall (thanks to the parapet), it isn't easy to support it.
What can I replace this with -- soft copper coil? Hard pipe with sharkbite fittings? PVC (???)
How do I support this from the top (I'd rather not drill holes in my wall)?
