Safe-T-Switch SS3 Condensate Overflow Shut-Off Switch for HVAC Systems

Why Every HVAC System Needs Overflow Protection

Clogged condensate drain lines are one of the most common causes of residential HVAC water damage. Algae buildup, dirt, dust, and debris can restrict drainage and cause condensate to overflow into attics, ceilings, walls, and living spaces. The Safe-T-Switch SS3 provides an additional layer of protection by automatically shutting down the cooling system before overflow becomes a costly problem.

Many HVAC professionals consider condensate overflow switches an essential safeguard for systems installed in attics, closets, utility rooms, and other locations where water leaks can cause significant property damage.

The best chew, play and teeth cleaning toy
Size: Blue
I have a 24 lb medium australian labradoodle multigen. She loves to chew and nothing soothed her teething like this toy. It also cleans the adult teeth that came in. So win win. The squeakers didn't last but that was my fault for squeaking it to tire her out in play. We personally love this toy and will purchase it again when it wears out. So thanks for a great product. 😉

Not indestructible, but pretty close!
Size: Yellow, Size: Yellow
I adopted a pit mix a little over a month ago, and so far he's managed to destroy every single toy he's had, including ones meant for aggressive chewers. He's a sucker for a good squeaky toy, and this had good reviews (and was affordable) so I decided to check it out. He's had his corn for a week now, and surprisingly, it's still holding up pretty well - though there are some caveats to that. My boy didn't even want to wait for me to take his corn out of the plastic bag, he too excited to get it. He went to town immediately, to the point where he was sitting in a puddle of his own drool after about an hour. He managed to squeak it (which I couldn't do myself), but still hasn't really gotten the hang of doing so - and the squeaker, when wet, does sound a little... Well, wet. He managed to have bite marks in it within the first six hours. Within a day, there were tiny bits of yellow rubber starting to appear anywhere that he played with this toy. A week later and there are some decent sized chunks missing from the corn - some of which I've had to cut off when they got loose and I worried about him choking on them. He loves his corn cob, and will likely get at least a few more weeks of play out of it before I have to toss it for his safety. I'm unsure of whether the squeaker is still functional, but he seems to love it whether or not it squeaks. Overall, it's not a bad toy for most aggressive chewers, but it will not last forever. The rubber is as heavy as the regular red Kong toys, but it feels slightly softer, which might contribute to his ability to break off little pieces. Make sure you keep an eye on your dog with this toy, or with any other, especially if they are chew goblins. But I'd definitely buy this toy again.

Solid piece
Size: Yellow
Border Collie loves it. Great for aggressive chewers. Prefers this to the carrot or the pineapple one. Probably better for large dogs than my medium size dog as there is some heft to it.
