Basements & sump pumps

Sump pump repair and replacement

A sump pump that won't run usually has a stuck float switch or a failed motor. One that runs constantly may have a bad check valve or a high water table. In Colorado winters, a frozen discharge line outside is a common cause of a pump that runs but doesn't empty the pit.

About sump pump service

Many Front Range basements sit in expansive clay with a perimeter drain feeding a sump pit. Spring snowmelt and heavy summer storms are when pumps get tested, and a failure during either one can flood a finished basement fast.

Discharge lines need to carry water away from the foundation and must not be tied into the sanitary sewer, which most local codes prohibit.

Sump pump service questions

Can my sump pump drain into the sewer?

Generally no. Most Front Range cities prohibit connecting sump pumps to the sanitary sewer because storm water overloads treatment plants. Discharge should go to the yard or a storm system where allowed.

How do I test my sump pump?

Slowly pour a bucket of water into the pit. The float should rise, the pump should start, empty the pit and shut off. If it doesn't, have it checked before the next storm.

How long does a sump pump last?

Often 7 to 10 years, less if it runs constantly. Many owners replace it before it fails, especially under a finished basement.

Do I need a battery backup sump pump?

It's worth considering if your pump runs during storms, since power outages often happen at the same time.

Why does my sump pump run when it's not raining?

A high water table, snowmelt, irrigation or a failed check valve can all keep water flowing into the pit.

Should my sump pit have a lid?

Yes. A sealed lid keeps debris out, reduces moisture and radon entry, and protects children and pets.
