I'm in the process of overhauling my entire bilge pump setup because over the last few weeks on the water before lockdown I witnessed 2 incidents in quick succession with vessels springing serious leaks and needing emergency assistance from CG / navy. It seemed like a 'message from the sea gods' and when I looked at the 'toys' that come with the standard bilge-pump setup I thought it deserves addressing ASAP.
1. New sump pump: to deal with the periodic accumulations that occur from minor leaks / condensation / overflows etc.:

This is a small capacity ~19 litres / minute diaphragm pump that means it is self-priming, can deal with minor pollutants that typically clog a centrifugal pump and can pump a combination of fluids inc air / water / oil / diesel / other nasties.
But to ensure it doesn't get clogged e.g. with hair, I'm putting a simple strum box (filter) on the front:

2. New bilge pump: to deal with worst case scenario of a serious leak that sump pump can't cope with:

This is a high capacity pump 4000 GPH / ~ 300 litres per minute to help buy time to either fix a serious problem or even prepare to abandon ship.
But all this has got me thinking - how far do you go with planning to evacuate unwanted water on a small private vessel where you have limited space for large capacity independent systems with redundancy etc?
What do others do?
