We've got a Bristol 53 with 2 showers, each of which has a little sump which runs to a pump
which has a loooong run all the way to the transom where *both* shower
drains tee into one of the bilge
discharges, above the waterline. Each shower
drain has an anti-siphon loop right before said tee.
What I'd like to do is get rid of all that excess hose, and have each drain hose go thru its anti-siphon loop closer to the corresponding head
, and then each discharge out through what would be dedicated below-the-waterline thru-hulls.
Forward, there is *already* an unused thru-hull that is closed off with a lovely Spartan seacock (freshly serviced) and a sturdy plug
. It's only a few feet away from where the end of the anti-siphon loop would be.
Aft, there's a presently used but soon-to-be unused (inlet for DC refrigeration
system which is going to be removed) thru-hull (also with a Spartan), about 1 foot away from the aft shower drain pump
I'd love to get rid of the total of about 40' of hose running around, but what I'm not sure of is if this idea is a good one. I know that the teeing into the bilge
discharge is a bad idea and needs fixing. Will the system I describe work
? Basically, shower sump
to pump to anti-siphon loop to below-waterline thru-hull, for each of the showers.
I could certainly add check valves in the run if that seems useful.
