What do you think of these water alarms?

[Spirit of Glenans]

But only a two year nonreplaceable battery life for a device you would hope will never be used in the lifetime of your boat. Can you see yourself making replacing these a regular part of your spring fitting out routine? I'm sure there are similar alarms which could be wired into the boat's power for a more "fit and forget" solution if you did want such a thing.

I doubt there is any such thing as a "non-replaceable battery". You might have to cut the casing open, un-solder the dead battery, solder in a new one and then repair the casing with Sika. or self-amalgamating tape. Nothing beyond the capabilities of any reasonably practical boat-owner.

That's me out then at £4 a pop I think I'd just get another one and confirm my place in the throw away society.

Couldn't you just use a proprietary hours run device.?

I couldn't find one cheap enough that could be reset to zero. Plus I wanted an alarm sounder as well so that plus a flashing LED and relay cost very little.

Why not just buy a bilge pump float switch (or the type with no moving parts) and connect a 12v sounder to it either instead of the bilge pump, or as well as?

Or just wire the float switch across a smoke alarm test button . Independent leccy source and another smoke detection source as well .......all for a tenner ......or a fiver if you are a cheapskate .

That's a smart piece of lateral thinking.
