 ## Basement and crawl-space sump pumps

Our sump pump work focuses on basement and crawl-space installations. Your plumber checks the pump, float switch, check valve and discharge line to find out why it's struggling — then tells you whether a repair or a new pump makes more sense.





 ## Why a sump pump runs nonstop — or won't start

A stuck float switch, a failing motor, a clogged or frozen discharge line or a bad check valve can all make a pump run constantly or not at all. Sometimes the pump is fine and there's just more water coming in than it was sized for. We find the actual cause, so you're not paying for a bigger pump that won't solve the problem.





 ## Repair, replacement and new installation

If the pump itself is worn out, we'll replace it with one sized for your pit and the water it needs to move. Adding a sump pump where there isn't one? We'll plan the location, pit and discharge line with you and give you one firm price for the whole job.





 ## Ready for storm season

Test your pump a few times a year by pouring water into the pit until it kicks on, and keep the discharge line clear. Ask your plumber about backup options if losing power during a storm is a concern.

 ## A few common questions.

### What happens if the power goes out?

Ask your plumber about backup options for your installation. The right choice depends on your pump, pit and how long you'd want protection during an outage.



### How long do sump pumps last?

Most sump pumps last several years, but it depends on how hard yours works. A pump that runs constantly, makes new noises or is getting older is worth checking before storm season.



### How much does sump pump repair cost?

Our residential diagnostic fee is $89, waived when you go ahead with the repair at the quoted price. You'll get a firm price on site before anything starts. Pay by cash, check or card, or ask your plumber about financing.



### Will a new pump fix my wet crawl space?

A pump removes water that collects — it doesn't stop water from getting in. If water is coming in faster than a pump should handle, your plumber will tell you whether it's worth talking to a drainage or waterproofing specialist.
