How Often Should Sump Pumps be Replaced?

There is no definitive guide on when you should replace your sump pump. Some pumps work well and last for as much as ten years or more. The best advice is to consider replacing your sump pump between 7 to 10 years of installation.

Very often, the best time to replace a faulty sump pump is when it is close to the end of its life and develops recurring faults.

Some of these faults can be easily fixed by a licensed plumber, like failed check valves for example. On the other hand, it is usually more economical to replace the sump pump when you’re dealing with other pump problems.

How Often do Sump Pumps Fail

How often sump pumps fail depends on a lot of different factors including how much work it has been doing, and if it is the right size and was installed properly or is properly maintained. Sump pumps that are the end of their life around 7 – 10 years are also more likely to fail.

Signs of a failing sump pump

Like all machines, sump pumps get old, wear out or just stop working. If you notice any of these signs, you should begin to seriously consider replacing your sump pump. Knowing when to replace or repair your sump pump can save you thousands of dollars in the costs of repairing a damaged basement.

Your sump pump is probably failing (or close to) when you begin to notice that:

  • Your sump pump is constantly cycling (turning) on and off
  • Your sump pump runs constantly with no reason
  • Your sump pump is running but failing to remove water
  • Your sump pump is taking too long to remove water
  • Your sump pump begins to make a lot of noise
  • Your sump pump vibrates too much when it is running
  • Your sump pump is beginning to rust

Different types of sump pumps

There are two major types of sump pumps and they both have their pros and cons. The two major types of sump pumps are:

1.Pedestal Sump Pumps

As the name suggests, pedestal sump pumps are mounted on pedestals above the sump pit. When water collects in the sump pit, a float activates the pump and it draws the water up and out of the sump, protecting your basement from flooding.

Pedestal sump pumps are a good choice if the cost is something you’re concerned about. They are generally cheaper. They are also easier to install and maintain. The major drawback is that they are not as efficient as submersible sump pumps.

2. Submersible Sump Pumps

Submersible sump pumps are installed directly into the sump pit. They’re more powerful, and a bit more expensive compared to pedestal sump pumps.

Submersible sump pumps are also more efficient. Because they’re installed directly into the sump, the pump draws in excess flood water through the intake valves and pumps the water out of the basement into a storm drain or a dry well.

The downside is that because submersible sump pumps are in constant direct contact with the water, they’re more susceptible to breaking down or needing regular maintenance and repairs.

Depending on what you want are and how much you’re willing to spend, you can choose between installing a submersible pump or a pedestal pump. Although pedestal and submersible sump pumps are the most popular types of sump pumps, there are other not-so-popular types of sump pumps like Water-powered Sump Pumps and “Floor-sucker Sump Pumps.”

Submersible Sump Pumps

A submersible sump pump can last for more than 7 years depending on a lot of things from how often it is used to how well it is maintained. Like I mentioned earlier, submersible sump pumps need a bit more attention. Because the motors are in constant contact with water, it’s easier for damage to occur. A lot of the time, you will need professional help if you have any issues with your sump pump.

Pedestal Sump Pumps

Pedestal sump pumps last much longer than submersible sump pumps. Some people even claim that they last for 2 – 5 times more than submersible sump pumps. That would mean more than 14 years!

It’s very conceivable since pedestal sump pumps stay relatively drier than their close cousins. If you live in drier areas that are less prone to flooding or huge rain events, then your pedestal sump pump may even last longer.

Commercial Sump Pumps

As with residential sump pumps, commercial sump pumps are either submersible or floor-mounted. Technically they’re called, “Guide-Rail Accessible Submersible pumps,” and ”Floor-Mounted Self-Priming pumps.”

The difference is that they are typically larger, more complex, and far more powerful than common residential sump pumps. Commercial sump pumps are long term installations and can last for more than ten years as they are usually built and used in large facilities. However, the exact amount of time a sump pump will last depends on other factors like how often it is used and how regularly and well it is maintained.

How Long Should a Battery Backup Sump Pump Last?

Sump pumps require electricity and usually run on your home’s main current which means you don’t need any special electric wiring for it. To prevent getting electrocuted if your sump pump malfunctions, however, you should also install a circuit interrupter.

When you’re installing your sump pump, you should have a backup plan for when there is a power outage. Your backup plan could be either a water-powered sump pump, a diesel/gas generator, or a battery-powered sump pump. Battery backup sump pumps usually last for several years, depending on how often you need to use it and how well you maintain it. Maintaining it usually means replacing batteries and running it routinely to make sure it’s in proper shape.

Since battery backup sump pumps are a backup system, you might not need to use it for a long time. Remember to run it periodically to make sure it’s working properly, so you don’t get stumped when you need it to come through for you.

How Long do Backup Sump Pump Batteries Last?

Sump pump batteries can last for up to five years. These types of emergency sump pumps can run for several hours and help keep your basement dry in emergencies while you fix the primary sump pump if it has failed or there is a power outage during a storm.
