Shop Vac with a 'wet' tank ... use the suction to 'bounce' the clog. If
that doesnt work, 'snaking' a long stiff wire up from the bottom outlet
is probably the best course. Compacting the clog from the 'up' side
with air pressure, etc. will probably make it worse.

Apply 1/4" mesh SS screens to the drain holes.
At 4-6 ft. length drain hoses and two 90 degree (dirt catcher) angles,
either opt to remove the 90 degree bends and replace with a single hose
(long radius bends) ... or physically relocate the seacocks elsewhere.

Does anyone have any ideas?

I've tried wrapping the dock hose in tape to form a tight seal and
blowing it out with water pressure to no avail.

I'm loath to run any kind of snake down there because it's just hose and
there's a seacock below as well. BTW the hose is 4'-6' long with at
lease two 90 degree bends. Not a good design and way too small if I get
pooped.

Would Peggy's beloved Raritan CP safely dissolve this stuff.
