From One Homeowner To Another
“This is a world class product and will set the bar for leak alert and damage prevention. From the efficient packaging to the flawless and simple set up, I’m sleeping better knowing the Guardian is installed and operating.”
“Amazing product. Easy installation. Works as described and is worth every dime considering the damage a plumbing failure can cause (bought after experiencing one). I definitely plan to get more sensors and the controller unit back up battery!”
“Super easy to set up. No plumber. Super easy to use. I now sleep better after just t covering from $40k of damage (plus lots of life disruption) caused by a $6 part that failed (braided intake line to dishwasher).”
