The standby 12VDC water pump doesn't work well with the Royal Flush toilets.  Is there a good reason to keep that system instead of replacing it with a standby 120VAC pump (assuming it fits)?  I just am not thinking of a scenario that takes us down to 12VDC without it being a total disaster regardless of the voltage.  We can normally find a cactus to lean against to resolve that problem
