This week end to my surprise there was 3 buckets of sand in my sump pump crock, need less to say it disabled the pump. This has never happened before . the house is aprox 10 years old. I have been checking everyday now there is a just a little sand in the bottom. Any ideas what could have happened and should I keep worrying it's going to happen again?
A section of the ground around the house may have collapsed causing sand to enter the perimeter drain pipes and make its way to the crock. Can you tell if there is sand collected in one of the pipes leading into the crock?
Usually the perforated drain pipes are wrapped in porous fabric to minimize sand getting in.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
I have not checked around the house for signs that the ground had colapsed, I will look today. The only visible drains I can see are the drains in the basemant widow wells. I well check them as well. Coming into the Crock there is just one big pipe and water tricles all the time. So far just a little bit of sand remains in the crock and seems to be the same amount each day.I will shop vac that sand out and see if I get any new Sand.
