Popular Questions About Quiet Sump Pumps

What Is The Quietest Sump Pump?

The sump pumps we've discussed in this review are quiet. Some produce under 30 decibels of sound, meaning you'll barely hear them from your bedroom when they're pumping water in the basement.

These pumps include submersible pumps like Wayne CDU980E and Zoeller M53 Mighty-Mate.

How Can I Make My Sump Pump Quieter?

Here are a few ideas to reduce the noise of your sump pump based on the source of noise,

  • Wrap the hose with foam insulation at the point it meets the floor or wall to eliminate the vibrations.
  • Reroute the hose pipe if it's encountering many turns and twists from the pit to the surface.
  • Replace the motor if it's making a squealing sound.
  • Unclog the discharge pipe if there's debris causing a humming sound.
  • Lubricate the pump’s motor to tone down its noise.
  • Replace your pump with a submerged one.

What Should You Consider When Buying Sump Pumps?

To help you compare the eight sump pumps we discussed earlier, these are the features to look for:

A Submersible or Pedestal Pump?

If you're looking for a quiet sump pump, choose a submersible design as it allows you to cover the sump pit, thereby reducing the noise.

If you have a small basin, then go for the pedestal design. This design is also cheaper, and it lasts longer than a submersible sump pump.

Auto Switch Over Manual Switch

You have to turn a manual switch on when the basement floods. That's a tedious process, given that you might not be at home when it rains, or the downpour may come when you're sleeping.

It should also have an alarm to notify you when the water rises beyond the standard level.

Durability

Choose a pump with a cast iron base to release the heat into the water. A plastic core can't do this; thus, such a pump won't last long.

Water Pumping Distance

The vertical distance of discharging the water, also called the dynamic head, tells you how many gallons the pump can remove per hour. In the pumps we discussed above, some can pump over 4,000 gallons per hour, discharging it up to 10 feet high.

Horsepower Matters

The higher the horsepower, the better the pump because you want it to pump high and fast.

Also, get a pump with battery backup, plus a long cord that reaches the GFCI outlet.

How Do You Maintain Sump Pumps?

Here are some maintenance tasks:

  • Check and remove any debris in the discharge pipe, intake screen, and vent hole.
  • Lubricate the pump if your model has parts that need such maintenance.
  • Examine it for rusty components that may slow it down.
  • Pour some water into the sump pit to turn it on.
  • Examine the backup battery and charge it ready for use.

Here's a short guide on how to maintain a sump pump:

As we conclude our discussion on quiet pumps...

The Verdict

The Wayne CDU980E is a submersible pump with a vertical float switch and a sturdy cast iron base that makes it long-lasting.

It discharges about 4,000 gallons of water up to 10 feet high. Another feature that made it rank first in our review is its top suction design that prevents clogging.

If you'd like a cheaper option, there's the budget-friendly Fluentpower Utility Pump that comes with a 26.2 feet cord. It not only drains your basement but also connects to a sprayer to irrigate your backyard.
