MT12 Leak Cable Replacement FAQ

Overview

Updated 1/12/2022

We recently discovered that all MT12 leak detection cables that have been built were not properly manufactured to specification. As a result, some cables may appear to work correctly, but there is no guarantee that the presence of water will be reported successfully every time. This article covers some of the frequently asked questions for the issue.

All leak detection cables on all MT12s are impacted, regardless of the firmware version. The 8 ft. water sensing cable, sold as an accessory, and every version of this SKU is also impacted.

No, we are only aware of a specific issue affecting the leak detection cable on the MT12.

Customers will receive a replacement cable, free of charge, with instructions on how to complete the replacement. This new cable has been thoroughly tested and will accurately report the presence of water. The replacement cables will begin shipping in March 2022.

Since we cannot guarantee that the existing cables will accurately report the presence of water every time, we are recommending customers stop using the MT12s immediately. 

The issue was discovered during internal testing of the cables. 

We do not have any reason to believe the cables pose any safety risks to customers beyond an inability to detect a water leak.

There is not a test that can provide accurate results. As a result, we are recommending all customers stop using the MT12 sensors immediately. 

Orders can still be placed for MT12s. However, orders will not be fulfilled until MT12s with new and properly functioning cables are in inventory. 

MT12 RMAs will not be fulfilled at this time. Customers can instead request a refund or wait for a working unit.

We will be sharing instructions for updating your address in another round of communications in February.
