This is what I had to deal with on Saturday. A flooding basement in an 18 month old house
What was the problem? The sump pump was submerged in over 6" of mud. Therefore it was fried.
We managed to scoop out a full 5 gallon pail of mud.
Looks like this is a MAJOR problem since you should NOT have ANY mud in the sump pit.
We put a new sump pump in ($538) and within 24h it was starting to fill up with mud again.
I’m now scooping mud out of the pit daily so the house doesn’t flood.
Let me remind you that this is an 18 month old house (to the day) and I’m now getting the warranty people involved.
