One of the big problems in bilge pump failures is low voltage. Years ago bigger boats used a 32 volt system, but there isn't as much 32 volt equipment available and the crappy builders that branch into bigger boats after doing speed boats don't seem understand the issue with long 12 volt runs. Some of my bilge pump problems I traced to too long of wire runs. In some cases my pumps were 60' to 70' away from the battery. The boat was wired will all the 12 volt going to the wheelhouse switches and then back to wherever the pumps were. I solved it by using relays near the pumps and the switches in the wheelhouse only run the relay coil. The relays are on fused lines, direct from the engine room.
Even though I had 12+ volts at the pump, when running, some were 10-11 volts.
I had the same issue with shower sumps.
