Water leak detector

That is how I have mine set up.  First is the auto water back up, then is my auto water off then are two lines - one internal and one for sprinklers.  So if water is detected the auto water shut off turns off water to the house/sprinkler but the backup sump pump water can still flow.  Only risk is that line/pipe isn’t what’s leaking.  Luckily my piping is exposed so I can easily put eyes on it to see if the copper line running to water back up is whats leaking or not.

Perfect - thanks! Nothing can be 100% but limiting risk tremendously is what it’s all about. Appreciate the info

Probably a dumb question but want to make sure I understand since I’m just starting to look into this option (water powered sump pump backup and auto shutoff). Does the shutoff get installed after the backup connection? I wouldn’t want the system to detect water somewhere and close a valve before the back up pump or it won’t work. 
 

Beginning the planning process here so any info would be appreciated.

The water pump has a separate sensor for water. It is not part of HA/C4. If water is detected on that sensor it allows the water pump to turn on and it's powered with city water pressure. I'm honestly not 100% up to tune with how it works other than that. The auto shut off is for other areas as my sump crocks are in an area with no water lines and is 1 ft lower lying than the rest of the basement.

Thanks Neo. Eggz answered my question. I was just trying to conceptualize in what order the physical auto shutoff valve would sit so it wouldn’t turn off the water to the Venturi pump sump backup.

Sounds like the order would be: physical main water shutoff then Venturi pump, then auto shutoff.

This way, if your sump pump fails and a water sensor goes off, it won’t turn off the valve before the Venturi pump (water based backup pump) and the backup pump will still work but the auto shutoff valve will work to shut down the other supply to the house if there is, for example, a hot water tank leak or a hose by a washing machine, etc.

Nothing is perfect so there are still ways for this whole setup to have issues but the likelihood is really mitigated with all of these systems in place.

Thanks again!
