Why does my sump pump only last about a year?

My sump pumps go out after about a year. They run heavy during the spring but not that much during the summer and winter. I have tried numerous brands including one with a lifetime warranty and one rated for continuous running. Still they only last about a year. Any ideas? Could there be an electrical issue?

We need to know what's going out on the pump.

This may sound a little obvious- but are you sure something's wrong with the sump pump? Or have you just needed to charge or replace the battery? If you've never replaced or charged the battery then that would be the most likely cause.

Is there a weep hole above the pump, but below the check valve?

How high is the lift?

What brands have you tried?

Are you buying at a big box store?

Are they made of plastic?

Have you tried a Zoeller cast iron pump?

Do you have a check-valve inline with the sump pump? If you do not have a check valve installed, when the pump turns off, any water left in the discharge line will run back into the sump pit, possibly turning the motor in reverse which could damage the motor. At worst, you will losse the "prime" on your discharge line.

+good answer..... a lift check type valve of the correct type in the right location or something similar could also be installed on the output line which would stop unwanted backflow on the pumps output side with less resistance. usually only if you have a high, long output line going outside.(need enough reverse pressure to trigger this type of valve, based on boiler systems, backflow preventer's purpose)

Since this post the problem has been solved. I read somewhere that your sump pump should be on its own cicuit breaker so decided to give that a try. had an electrician come out and and move some things around and put the pump on a new breaker. I have now been using the same pump for 4 years with no problems no matter how much it runs.
