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

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.

This water level alarm functions according to how the manufacturer said it will. When using as a low level indicator the hallow cylindrical float moves upwards as the float assembly is placed in to the water. As the water in tank or container drops below the level of the float, the float drops and triggers the alarm. The installation instructions are very clear. There are small marks on the top of the cylindrical float. For low level indication the marks on the float face upwards, for high level indication the marks face downwards. This is a good product for the price.

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.

The build quality could have been better. You can tell that the product came from inexpensive material. In the end, after addressing the bulky build, it worked for what I needed it to do.

I like that the volume control/on-off switch is easily accessible on the side of the unit. The siren is SUPER loud so I set it to about 1/2 max volume. I'm not using the "high level" alarm so I taped that sensor so it would not accidentally be set off. By the way, that sensor can be used to test the battery and/or trigger the siren so you can adjust the volume levels to your liking (without having to fiddle with the underwater sensor.

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!

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 product was purchased to monitor the level of a swimming pool after being winterized and a cover installed. The alarm can be silenced and only the flashing lights will alert, or the audible alarm can be set to various volume levels to be used along with the flashing lights. There are two sensors permanently attached. One alarms for a high level and the other for a low level. The permanent battery can be charged using the integrated solar panel or the included cord can be plugged in to a USB phone charger for ac operation. I have recently received this product so I can't speak for the longevity but this item performs as described with a good price point.

Está un poco corriente

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

Bon produit, installation facile, offre une bonne performance et fonctionnalité.

Nunca funcionó

Was simple to setup and it worked immediately. We’ve had flooding all summer and I added one of these to the ground by my sump pump to ensure water wasn’t escaping during an unexpected power outage and rain storm. 5 stars for the peace of mind!
