Sump well keeps filling up
Have a concern regarding the sump pump well filling up and causing the pump to run every 60 seconds or so. Have been in our raised ranch home for 10+ years and have sump well in the garage. For the past year it has started to run frequently and this winter with all the snow we have had in Chicago it runs constantly. However, this was not the case as until the past 18 months or so. Any suggestions as to what might be causing this? I am concerned that we have an issues with the incoming water line from the city. Could that be a possibility?

Simple enough to find out if it's leaking.
Shut off all the valves to the toilets (to eliminate the possibility of a flapper leaking)make sure there's no water running in the house.
Go outside and uncover where the city shut off and meter are and see if the small dial is still turning.
It should not be moving at all.
More often in older homes they routed the outside drain tiles into the inside pit to be pumped out.
Never made any since to me.
A couple other things it can be is a bad or no check valve. The pump shuts off and the water still in the line drips right back into the sump.
Or the outside line is plugged up from freezing where the water comes out.

Vote #2 for the check valve. Just because it's the most likely thing to cause water to fill the sump quickly.

Joe, it's colder in Chicago and Minnesota and the Dakotas than Virginia. the drain tile runs to the inside sump because otherwise you would freeze out and ruin the pump over and over. likewise our water meters are inside.

my test for the feedline leaking would be shut off the water at the meter (both sides, gate valves always leak once the shine is off them,) get the biggest bull screwdriver you have, put the blade on the pipe and the handle on the bone by your ear. if you hear water, there is a possible issue.

the other two likelies, much more likely, remain a frozen pump outlet line outside and a leaky check valve. they grow hair over time from stuff growing in the water. just don't crank the replacement too tight, that can jam them, too.

sig: if this is a new economy, how come they still want my old-fashioned money?
