I have a diaphragm bilge pump--they have internal check valves, so no run-back.
The photo shows the initial setup. But the TAFG makes four separate bilge compartments and the strumbox pickup was only in one of them. Limber holes leave some water in each.
I removed the strumbox and added five feet to the lightweight bilge pickup hose, incorporating an in-line debris filter. .
Now the hose will reach all the way to the mast, to suck out water under there, or in any compartment.
The lengthened hose normally rests coiled in the main bilge, weighted at the end so as to remain low, where the automatic Water Witch can empty rainwater.
Manually suctioning sections with this system gets out most water, so that only a few paper towels are required for the absolute dryness my psychiatrist said would make me feel better and possibly stave off expensive hospitalization.
We all know that some water in the bilge is normal. I don't know why it drives us nuts.
