Leak protection from permanent dock water connection

[markc]

I know those of us that have a dockside water connection have discussed the potential of a catastrophic failure of an internal pipe leading to sinking, so I thought this would be perfect to prevent the problem - AquaPal - Smart Water Monitoring & Control to Prevent Damage

No affiliation, but I have bought one

Wow M, what a technological solution.
Having used direct dockside water supply for decades, occasionally I also thought about the risk of flooding the boat.
Eventually, I always ended taking the easiest route, i.e. close by hand the dock valve, whenever I leave the boat for more than a few hours.
By now it became a sort of habit/routine, together with lifting the passerelle...

BUT, even if I never bothered trying it, I did find another solution, already years ago.
Simpler than the one you found and with no remote monitoring, but also cheaper.
It's a mechanical valve, that should just be fitted inline to the dockside supply.
It closes automatically if the water flow reaches 50 litres with no interruptions, but if the water stops flowing before reaching 50 L (say at 10, 35, 49, whatever), it self-resets and starts counting from zero again.
I always thought that it's a nice bit of kit also for explaining guests that they shouldn't leave the shower constantly open...
...Though I'm not sure of how the Admiral could react, if she would experience a blockage herself!

More about that here.

Looks good. They say 3/4 is a standard U.K. pipe ... but it isn’t so you may need to make up and adapter. I don’t have constant Boet internet when I am not there but it does look like a nice bit of kit. Does it need internet to make its “ decisions “ Re a leak ?

I looked at these. I have had taps left on and arrived with half water tanks. What stopped me was the reset procedure on the ones I found was tricky and would mean entering the stern locker where the pump is.

I did try to make a water running more than5 min alarm but I never finished it !

Yes P, I saw that too a while back, I think via jrudge but decided that 50l was too low to trip the device and I too thought that the reset procedure would be a pain, even more so covered in soap suds from a a long shower!

I have tried to get into the habit of turning the dock supply off when leaving the boat for a few hours, but the risk of flooding whilst asleep is still there. When leaving the boat between visits I always disconnect the supply.

I am guessing that this device will shut off even if there is no internet, and I presume they are supplying adapters for 22mm pipe, although the boat is in 15mm - making up some different adapters will be simple enough. I also have 220v power close to the incoming water supply in the ER so installation should be a breeze (famous last words!)

It obviously won't be until next year that I get the chance to fit it, but I'll add to this thread when I do

I suppose the best thing you can do is compare the rate of flow of the water supply with your bilge pump’s

 

[jrudge]

having has this I can confirm, the pumps run faster than the boat pump - but mains water maybe different given it is also continuous!

I had a "chirp" from the bilge alarm. First one I ignored / was not sure what it was. The second chirp - better look. Leak in hot water pipe. I would;d love to say it left the engine rooms sparking - but it didn't!

Mains pressure from my dock connection is very high, although I do have a pressure limiter just past the inlet. I would say it takes about 10-15 minutes to fill up our 800 litre water tank, so 3,000 - 4000 lph. £130 seems cheap peace of mind
