Water Sensor Instructions
Some of our products may have outdated instructions that were prepackaged during manufacturing regarding the water sensors. Free water sensors are ONLY available with purchases from Xtrememats.com. If you purchased elsewhere, you are not eligible for a free sensor. If your water sensor instructions mention an expiration date but you have the newer model water sensor (pictured above, featuring our logo) then your sensor will NOT have an expiration date because the batteries in the newer models are replaceable. The previous model of water sensor we were offering was disposable and did not have replaceable batteries, and thus, had an expiration date.
