Question: can i just buy alarm box my alarm is only problem wont sound on test
Document: A  Great High Quality Alarm. Well worth the little bit of extra cost over cheaper models.
It's located at the bottom of a hill, so that probably causes underground water to rise too.I highly recommend the sump pump alarm. It sounds the alarm loud enough to hear it throughout a two level home. The 9v battery back up also puts my mind at ease. It's easy to install and it's solidly built.
I've had this alarm for more than 6 months. It's great. It's hooked up to my almost tired-less sump pump. It has sounded the alarm 2 times recently. My super overworked sump pump has taken a break twice, so the alarm let me know when the water reach a certain level in the sump pump well. After clicking a button on the unit to turn it off (the unit resets automatically at that point), I simply moved the sump pump cover over to see what's going on.
Very well built product that offers peace of mind in avoiding a flooded basement. Highly recommend this item compared to the less expensive similar ones that are cheaply built.
The unit does plug in and has a 9V battery backup. After I installed it I tested it both with the power on and 2 weeks after it being unplugged. When I lifted the float it worked as advertised. The horn is very load, but can be toned down by putting a piece of electrical tape over the hole to suit your needs.
So far we have it installed and have not had it go off. So if we have issues I will come back to update.
Answer: no
