I get very nervous when I see someone interrupt the dedicated line for the
bilge pump to add another device. This is not the place to drain showers,
sinks or other fixtures in my opinion. I would rather add another through
hull above the waterline for the shower sump...with a proper anti-siphon
loop installed. ( I have installed thru-hulls while at the dock, in calm
water, by myself using a length of rope.) I would also recommend removing
the sink drain from the other bilge pump line and instead "T" it to the
shower drain outlet. This would be much safer. Check valves on bilge pumps
are not recommended.
I am not sure of the "filtration" you mentioned. The showers sumps I have
used are not filtered and have an automatic pump installed in the box. Soap
scum does have to be cleaned out periodically depending on how much use it
gets. I would think a filter would last about 3 showers before clogging.
That's the way it looks to me.
