On Wanderer, when we run one of the toilet pumps, enough of the seawater goes to the bilge to activate the bilge pump (of course the bilge had to be partially full for this to happen, or the seawater pump was run for a longer time).

The seawater lines to the toilets have a vent loop in the engine room that has a tube going into the bilge.  As far as I can see there isn't a mechanical vent there.  So the conclusion I come to is that the seawater lines are clogged.  I haven't heard about this on the forum here so I'm wondering: is this common?
