Asurity WS-1 Wet Switch Flood Detector for Secondary Drain Pans, 24VAC Hydrophilic HVAC Flood Detection Shutoff Switch

My HVAC man suggested I get this hockey puck size water detector that will shut down the AC unit if even if it senses a couple of drops of water leakage. This will prevent the AC unit from dripping water into your pan which can handle only so much water before spilling over on the floor, wetting your basement, until you realize your system is leaking. If your AC unit is in your attic, this device is an absolute must to prevent ceiling and wall and floor damage to the room below the unit. My AC man showed me how the typical auto water detecting devices are mechanical and water must rise high enough to push up the float to turn the system off. This may fail completely, but even when they do operate properly, your drip pan is already nearly full of water. Eliminate any significant build up of water by installing this device which operates electronically instead of mechanically.

After suffering the effect from a 1 in water pipe leak in my home served with a well and submersible pump, I decided to add a “Fail Safe” layer of security. This is in addition to the other layers I have using wireless connectivity through my router. I wanted this layer to be as simple as possible with no wireless, internet, etc I fabricated a solution using this device directly connected to a 240v relay in series with the pump turn off switch. It works as desired, with no issues from having to initialize after power, etc. The WS-1 appears to be fabricated as a commercial level product, above that of many of the homeowner devices available.

Easy to install just 2 or 3 wires (did the install a few months ago) just swapped out the old one wire for wire. New one did trip due to setting it on my pant leg in the attic in Texas as I installed it. Recommend not setting on a sweaty or wet surface for quickest results. Saved a lot on an AC repair call.

I installed this water sensor on whole house RO water treatment system. I poured a little water on the floor next to the switch and it instantly shut of my system. In the past, pipe fittings have leaked and flooded the room housing the water system. This is a quality packaged product. It is well engineered with a test switch and a clear wiring diagram on the nameplate. It comes with 6 ft of excellent sized wire. I just connected the wires to the 24 VAC control power in my system and it worked perfectly.

Works good

Bought this one to replace one just like it that was shutting down AC too often. The replacement is sensitive too. The switch is setting on concrete below the condensate pan. The felt pad on the switch is in contact with the concrete. Occasionally, apparently due to humidity, the switch shuts everything down but will not reset until the felt pad is dried out.

Included 6' cable made it easy to install on my system and the heavy weight of the puck makes it stay put. Test and reset buttons are convenient for verifying it is correctly wired. Material on bottom of the puck should wick any moisture and alarm quickly although I have not actually tested with water. Long term update: Unit is still working 4 years later and actually detected a leak and shut down the system when drain line had a problem.

Replaced an equivalent item that apparently went bad. Same color wires. Attached like for like and voilá it works. Very easy to install if you already have one in. I wouldn't have had a clue if it was a de novo install.

I am powering this switch with a 24 VAC transformer. I have connected this switch to a RIB 24P relay which is wired between the switch on the wall and the pressure switch on my pressure tank. I wired relay to the normally closed side. I place the wet switch on the floor of my utility room. If it senses water, it sends a 24 VAC signal to the relay which opens, and disconnects power to my pump. It seems to work well. I don't know exactly what size my pump is, but the control box on the wall is rated to 3/4 HP.....therefore, my submersible pump will be 3/4 HP or less.

très sensible à l’eau et réagit rapidement ...

I try and test this switch once a month. So far it has been reliable, thankfully we have not had to rely on it for flooding.

Product is as advertised. Shipping was quick. I wanted another one 3 days after I ordered the first one and SURPRISE SURPRISE the price went up 5 bucks. Keep it!!
