And I third it. When I refit Island Eagle I installed two Sealand diaphram
pumps on the aft black water tank and the grey water tank. I left the
existing macerator pump on the forward black water tank. That one failed the
first year of use, so I replaced it. Last summer the replacement failed. It's
now been replaced with a Sealand. Score Macerator 0, Sealand 3.

As for the switches, all of my pumps (black, grey, water transfer, fuel
polishing) are equipped with Intermatic clockwork timer switches, like this:

They are dead simply to install and debug, and you can pick them up at Home
Despot. If you are really keen, run the pump right when the "Tank Full"
indicator comes on, make a note of how long the tank takes to empty, and the
put a label beside the switch so you know how long to run it for.
