Hello Charles,
See if I can get all the answers in this email:
It is schedule 40 now and had to be centered in the floating section to keep it
level, This will be 4 feet off center. There is no handrail on the floating
section so it will be mounted to the deck with 2' risers to the hose valves.
Leaning toward schedule 10 to save 10# per foot of weight.
Art:
Well from low tide to high tide it has to get 12" shorter, I already have a
flex hose at the top and there is a custom made Metraflex "V" hose at the
bottom (now ON the bottom) to handle the movement. The "U" hose did not have
enough movement range.
Scott:
Nice idea, I will look into those.
Matt:
The water is brackish, Tide going out is fairly fresh, tide coming in gets some
salt into the area.
John:
I looked into HDPE pipe on the initial install back in 2010. It is above ground
almost a 900 foot straight run out to the dock head, From my notes there was
about 6 feet of difference in the length of the pipe due to temperature changes
where is was not buried, The other was the sunlight exposure. I know of 2-3
docks in this area that are closed for use due to the HDPE welded joints
separating under the decking and there is no way to weld it for a repair.
Heck we even have a few in this area installed with white schedule 40 plumbing
pipe with glued joints under the decking.

Hello Sprinklerforum,
Looking for suggestions for pipe to use on top of a floating dock for the
Manual Dry standpipe. We had pipe under it but due to structural failures of
the dock the pipe is now in 3-5 feet of muck in the bottom of the river.
Looking to run the pipe on top of the dock. There is no access under the dock.
Dock is Aluminum decking welded into place, +/- 185' long, last hose valve is
about 1000 feet from the FDC. Had 6" all the way when it was put in 5 years ago.
