Cost to Replace a Sump Pump
Replacing a sump pump involves disconnecting the old unit from its discharge pipe, lifting it from the sump pit, and connecting a compatible replacement. The work requires careful handling of the electrical connection and PVC discharge line, plus a weep hole and a check valve in good, fresh condition. Homeowners often take it on when the existing pump is failing, aging, or due for an upgrade.
Common reasons homeowners do this job
- The existing sump pump is failing.
- The pump is more than five to seven years old.
- The existing check valve is worn or aged.
- The discharge pipe needs replacement parts.
- A homeowner wants to upgrade the pump.
DIY or call a pro?
This is a legitimate DIY project for someone comfortable disconnecting the discharge line, cutting PVC, drilling a weep hole, and reconnecting the new pump. Consider a professional if there is uncertainty about selecting a pump compatible with the pit size and discharge requirements or about any installation step. Disconnect power at the breaker before touching the pump, avoid standing in water while handling electrical components, and wear gloves and eye protection when using PVC cement and tools.
Frequently asked questions
- Can I replace a sump pump myself or should I hire someone?
- A homeowner can handle this moderate project when comfortable working with the discharge pipe, PVC fittings, and the pump's electrical connection. Turn off power at the breaker and unplug the old pump before starting. A professional is worth considering when matching the replacement to the pit and discharge requirements or reconnecting the system feels uncertain.
- What can make sump pump replacement cost more?
- The price can rise with the job's size, labor time, and the materials needed, including a replacement pump, check valve, PVC pipe, and fittings. Haul-away of the old pump and a minimum or trip charge for a small job can also affect the total.
- Why does the discharge pipe need a weep hole?
- The weep hole helps prevent airlock. Drilling it in the discharge pipe is an important step before placing and connecting the new pump, so make sure to include it.
- What should I check before buying a replacement sump pump?
- First determine whether the existing pump is failing or more than five to seven years old. Then choose a replacement compatible with the sump pit size and discharge requirements, and inspect the existing discharge pipe and check valve for parts that also need replacement.
