Hi, Is anyone able to identify what this box is connected to my pipes under the kitchen sink. This is leaking and I need to replace, but need to know what it is first.
Thanks

Anti flood device for either a washing machine or dishwasher

Seeing as water finds the lowest spot are you sure it`s not leaking from a joint above?

And it looks like the valve above it is leaking not the antiflood

Is that supplied as part of the appliance then?

I assume its just a SOV the appliance opens when it needs to draw off water?

It's an anti flood device. It's a hose within a hose with the internal one carrying the water. If that ever bursts the outer hose fills with water and eventually (or quickly depending how bad the leak is) reaches the cylindrical anti-flood device which contains a float that moves and shuts off the supply to the leaking inner hose. Not a bad idea really.

An elegantly simple solution. Very clever

So being a bit thick here, this device ......
1. does it stop the waste water glugging up ..and flooding your gaff..
2. or does it stop what ?

Our Bosch dishwasher has a solenoid valve on the cold water connection. I’d never given it much thought why it was there. I guess this is an analogy equivalent.
