My new house (just moved in a few months ago) is 5 years old, on flat terrain in Indiana. The basement floor is about 8-9 feet below ground level.
We have a sump pump, which runs for ~5 seconds once every 10 minutes or so. This worries me, as it seems very frequent. I've never lived anywhere that had a sump pump before, so I have no experience to draw upon. One friend told me that such short cycles, so frequent, are a bad sign re: the sump installation.
The basement, half of which is finished, seems completely dry and there are no signs it ever got wet.
I'd like to investigate the sump pump to verify it has a battery backup, and maybe investigate the pit to see about how deep it is, etc., but the sump area is sealed up tight as part of the radon remediation work done at least 4 years ago (either when the house was built, or when the first owner sold it to the second owner; I'm the third owner). Basically there is a fan system that sucks air through the sump area and out the side of the house.
There is one other opening in the floor, a drain hole where the furnace humidifier and the pressure relief valve for the water heater discharge.
I'm extremely handy but admit to being intimidated by a lack of experience in this area. I can always call out the radon remediation people who closed it all up and have them come out and poke around, but that will be pretty expensive.
Any thoughts on all this? The thing has apparently been working fine for years, but I worry about a power outage possibly resulting in a flood, and frankly I hate hearing it cycle so frequently.
I'd appreciate any input.
