How to Choose a Sump Pump
Like most of the equipment in your home, your sump pump will eventually wear out. Most have a lifespan of about 10 years, but how to choose a sump pump? Do you simply buy the same model and hope for the best?
Is this something you can put off? Probably not. With all of our heavy precipitation and low elevation, a working sump pump will ensure that your basement and foundation remains sound and dry.
When to Replace a Sump Pump
If you’ve checked out our sump pump maintenance guide, you should have a good idea of how well it performs. One thing to note is that the cost of repair is often almost as high as buying a new pump.
If you’re still on the fence about replacing it, look for the following signs:
Pump runs constantly: This may be that the float switch has failed or the pump is under-powered.
Pump is clogging: The water overflow in your sump pit often contains dirt and debris, and this can clog the pump.
Erratic operation: Most sump pumps operate automatically. However, if it’s cycling off and on, there may be electrical problems or a failed check valve.
Noisy operation: While no sump pump is completely silent, loud noises are a sure sign of serious problems.
Tips for Choosing a Sump Pump
Now that you’ve decided to replace your old sump pump, keep the following tips in mind when shopping:
Two types of sump pumps
You’ll find two basic sump pump configurations on the market: pedestal and submersible. Pedestal types have the pump motor above the water level. Submersible pumps have the motor below the waterline.
Pedestal sump pumps are generally much cheaper than submersible pumps.
When possible, choose a submersible pump. They cost more but offer a number of major benefits. Submersible pumps are much quieter.
Also, since they fit into the sump pit, you can add a cover, reducing the chance of accidents. The lid also keeps the air in your basement drier, which is the whole point of having the pump.
Materials
Some sump pumps are made of cast iron and some of PVC plastic. Choose cast iron for two important reasons.
First, they’re more durable and can survive debris in the sump pit. Secondly, they can help dissipate heat into the water reservoir, reducing the chance of the motor overheating.
Power
The longer the discharge run, the more horsepower you’ll need for your replacement sump pump.
If you’ve moved the discharge point or are noting a higher volume of water intake, you may need to upgrade to a more powerful motor.
Durability
Look for a sump pump with a durable housing, such as those made from stainless steel or employing an epoxy coating. Your pump will be in water and choosing a resistant model will lengthen its lifespan considerably.
