Water shut off device

[townfanjon]

Hi Boys , a customers just had a major leak from an unvented undersink water heater , water ran for hours. I replaced heater this morning and customer wants a shut off device , the type that automatically closes after a pre determined amount of water has passed through the device .
Anybody got any personal recommendations.
Thank you in advance.

Sounds like you want a sure stop device with leak sensor pad/probe.
Manual switch and
Auto switch off when leak detected..
Believe they only do local areas due to cable and leak sensor.
Might be the type of think your looking for.

Only ever fitted manual switch ones.
When stopcock hasn't been accessible in commercial places.

Effective systems are not cheap! Grohe Sense Guard is probably the best - you can zone them and configure the “shut off” point.

Tea Guard is also very good ( they are designed to protect vending machines), but work well in a domestic environment.

Both are around £600.

Sure Stop (in my view) is really only a remotely controlled isolation valve. In auto form, it lets so much water through that the damage has already been done before it shuts off.

I've always worried about how reliably these gadgets actually work and who's liable when they don't. If the customer pays a plumber to supply and fit a flood prevention device and there is a flood that it fails to prevent I think that they might come knocking expecting the plumber's insurance to pay out...

This is your American Waterblock, its identical to the Italian one ...except its moulded in black, again the reset needs to purchased and fitted after you dial in the set volume of water to pass through before activation. centralhearking I have fitted 100s

Yes me too , its the management company that have asked for it , theres 2 more of these undersink unvented’s and they are a similar age to the one that leaked .
What I would do on a job like this is supply the part at cost , a copy of the installation instructions and a “disclaimer”on the bottom of the invoice .
