My fiancé and I are under contract on a new home which we are concerned it might be built on an underground spring. There are two sump pumps in the house, on opposite corners of the house. Both times we have seen the house was after a few days of no rain. One of the sumps only gets a tiny bit of water from the French drain leading to it. The other sump, there is a visible stream of water from both pipes leading into the hole. Every half hour or so, the pump kicks on and dumps about 3-4 Gallons (wild guess). We are concerned about a) flooding our basement, and b) future foundation issues.
Thing's I've researched:
- The water bill is not very high, indicating there is not a leak in the mains.
- The neighbors' pumps kick on intermittently also, but not to this extent
- It is a 25 year old house, and there is no sign of foundation issues, and very little settling
- Also, as a 25 year old house, it has been doing this for as long as any of the neighbors can remember, and do not know of one instance of the basement flooding.
- Tried looking on the county website to see if there was an underground stream, but couldn't find anything.
- Basement has no smell of mold or anything like that.
So my questions are this:
- Is this a red flag / deal breaker? Is this just something we need to keep an eye on, or is there a possibility that the foundation might crumble at any time?
- Assuming it is not critical, what precautions should I take? I already plan on buying a water-powered sump pump as backup, and getting a couple alarms for both pumps. The current pump already has a battery backup.
- The water looks clear and fresh. What can I do with all this water? Anything productive?
Update: To answer some questions, the home is in Maryland (US). There is a slight slope to the road and we are closer to the bottom, though it is so slight, I didn't even notice it until a neighbor pointed it out. It's a suburban area, homes line both sides of the street, spaced roughly 30 feet apart. I don't mind sharing the water with the neighbors...in fact I encourage it. The more water they take, the less I have to figure out where to direct.
