5 STARS, its something that you would rather have and not use than to need it and not have it. This is quite loud but its there for a reason, dont flood your house or foundation.Plug it into a spare breaker, try not to use the same one in case the breaker trips due to a problem with pump so it can alert you of the issue ASAP.So far its working, I will update if something goes wrong or if it gets better than it already is.

I live in the midwest, and no matter what steps you take to avoid it, at some point your basement or crawl space will flood. It's inevitable. I had a line powered sump pump with a water powered backup and both failed. I replaced the combination with a new line powered pump and battery powered backup pump, with an alarm to let me know if there was a battery pump failure. Once again both pumps failed, and the alarm never notified me.You can't beat nature and the water is going to come. I can deal with it if I know about it. The OELFFOW Sump Pump Alarm is a part of my solution. I still have the deep cycle battery for the failed pump, and am using it with an inverter to keep the new pump powered through a power failure. Having two pumps didn't help, but a good backup for power failures will. If the OELFFOW Sump Pump Alarm sounds, then I know I have to throw in my standby pump.You can adjust the sensitivity by moving a counterweight on the float, so you can arrange for it to trigger at the point best for your application. The water alarm sounds at 110 dB, which you should be able to hear far away. The bright red flashing light is easily visible as a trouble indication.This is a solid industrial grade product, well worth it to protect yourself from water infiltration.

It does work for an alarm, but is not very loud. The dog may hear it, but I would not hear it at all from a basement sump pump. Good that it's easy to install because there is not one word of instructions. The light is bright enough if you're in the same room.

I have a smart water sensor on my sump pump, but sometimes it disconnects from my wi-fi, so I wanted a non-smart backup system in place. This was incredibly easy to install. I lowered the float down into the water and it went off right away. Nice to know it works! I adjusted the float so it was in a better position and down to the main unit on my concrete. I used a hammer drill the Drone with the concrete and the included anchors and screws to hold it on. Very secure attachment! The loud alarm and the light are very helpful should I have any other issues with my sump pump not working. It is far better to get woken up by an alarm than to find water or Foundation damage weeks after your sump pump stopped working. I'm very thankful to have this extra security measuring place.

We needed this for our septic tank insert. Works great for the price
