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 .

This unit is actually specified by insurance companies esp. fitted to mains fed office water coolers as a reliable flood prevention unit in UK, it originated in Italy to protect expresso coffee makers in restaurants, I would include the disclaimer at the end of the invoice we have never had one fail in the past 8 years or so. centralheatking

Be careful installing these devices and make sure you know the specifications of each device.
A few years ago a Plumber I know installed some of these types of devices on washing machines.
A washing machine hose split and caused extensive damage to a property.
There was a lengthy legal battle on who was liable for the damage.

The flow rate the device was designed to shut down at was 14 litres per minute.
Due to a split hose pipe, the flow didn't reach that and, hence, the house flooded.
The water was running at close to the 'shut off limit' for 2 days.

correct Oz there is in fact no perfect automatic shut off device really. The waterblock will allow a minimum or maximum of water through in one go so a tap turned on will not trip it as it re sets itself when the flow stops. We did extensive research and still look on this subject for commercial reasons. Its how all these units respond to the specific problem which is the trick in choosing them. In fact a combination of two of the cheaper units can answer almost every scenario. centralheatking
