High / Low Water Level Sensor Detector Alarm 120 dB Red Strobe Siren, Adjustable Alarm Volume, Sump Bobber Water leak Sensor,16.4ft Probe Cord, Suitable for Water Tank/Aquarium, Swimming Pool/Basement

Works just like it's supposed to do. Works really good very loud audible alarm which can be adjusted with the volume control and with flashing lights.Using it for an a/c by SereneLife Small Air Conditioner Portable 12,000 BTU with Built-in Dehumidifier - Portable AC Unit. Drip or drain line into a 🪣 or waterproof leak proof container, it takes about 5 hours to fill my 2gal container. I have a pool pump which when alarm goes off, I push 1 button on a remote to drain water container outside. Everything I needed to setup and run a/c, I purchased from Amazon.

This thing works great for my well tank that supplies our house. I put the low sensor about 2 feet from the bottom and put the high sensor right at the top where the tank necks down. When i'm filling it and i hear the alarm go off we cut the well off, then drain a few gallons of water and the alarm shuts off. I'm glad because this allows us to save water and not overflow the tank.The alarm is extremely loud. It is high pitched so the sound doesn't travel super far, but we are about 50 yards from the alarm and can hear it go off, we leave the window cracked to make it easier to hear. At point blank this thing will make your ears ring.I do wish there was an indicator that whenever you first turn the alarm on it beeps one time to let you know the batteries are charged. I wonder about that battery dying one day and we don't realize it, we rely on this to tell us if our tank ever gets too empty. I'll probably end up replacing the battery once every 6 months just to be on the safe side. Well worth the $35.

Easy to install and broad range of alarm sound level.

I use this water level sensor for my 3000 gallon water tank to indicate 500 gallon drop in level. So far it is working great.

The 2 hanging probes feel very light and flimsy. You will definitely need some of counterweight to hold down the float into the tank otherwise the long wire just curls up and prevent float to hang down.

I use it for my pressure washing business. The alarm lets me know when my tank is full, so I don't have to monitor it, and it also lets me know when I am getting low on water so I have time to rince off any soaps or chemicals. I have been using this alarm for a year now and it has healed up impressively well. Definitely a good deal.

This is a high/low water level alarm. I only needed the high water level alarm, so I eliminated the low level float. The only downside was I had to cut the sensor wires to attach to the piping. It worked very well. The alarm is really loud so it can be heard from the basement. If needed you can extend the wire to bring the alarm body to a location more suitable for your needs. Hope this is useful!

It works great once you know how to use it. For the two sensors that are attached, one is for the water level dropping too low, and the other is for the water level rising too high. You need to play with float on each sensor to determine which is which. I use the later. Either sensor will trigger the same alarm. For the sensor that determines the water level dropping too low, I wrapped a twist tie underneath the float to prevent it from dropping and triggering the alarm. For the sensor that triggers the alarm for high water levels, I let it dangle at the level at which I want the alarm to sound.The only other complaint is that if you decide to mount the alarm, which is exclusively using screws, when the battery needs changed, you need to dismount it by unscrewing all the screws. You then need to unscrew the back of the alarm to gain access to the battery compartment.Despite the unclear instructions and the inconvenient access to the battery compartment, I would buy it again because it successfully meets a critical need at a reasonable price.

Easy installation, and works well.

Works well. Adjustable volume, very loud at the top end

I wanted a single (high water) alarm on my septic tank, and this one comes with two sensors--high and low. It's easy to defeat the 2nd alarm, just cut the wire. This device requires a 9V battery--it comes with a cheap dry cell, which I don't expect to last long. I recommend putting an alkaline in right away, because it's not easy to replace the battery once installed--you literally have to unscrew the alarm from the wall to replace the battery. Also there is no test feature to let you know if the battery is good or not when you turn the unit on (perhaps I could rig up the second input in this case, but that is extra work and should have been built in.) The alarm does have a bright flashing red LED and the volume can be turned up to ear piercing at close range so I'm hopeful it will work fine. It's also nice that this unit doesn't require line power, so it can go pretty well anywhere. The magnetic float switches seem to work ok when I tested them. (It's likely this unit would work with any closing-circuit type sensor, but I haven't tried yet.)

Fitted in a sump around a swimming pool. Works perfectly to clear the ground water. Light and audible alarm warnings are great.
