Greetings!
For more stable function and operation, we have made some improvements on our Leaking Alert. Kindly inform you here.
Please check below pictures, our original Leaking Alert with 3 connectors, one for AC adaptor, another one for Ball valve, and the third one is for possible extra Leaking Sensor connects.

But we found some of customers will misconnect and most of customers don't like the possible extra Leaking sensor connector, so we removed that, changed the mould and improved the main board.
For future orders, the Leaking Alert you receive will be only two connectors, one is for AC adaptor and another one is for ball valve. Check the picture below:

Kindly Noted.
If any confusion or requirements, Pls contact with your account manager.
Thanks
