Quietest Sump Pumps Buyer Guide: Important Factors to Consider
In this section, we shall be looking at some of the most important factors to consider before buying the quietest sump pumps that meets your specific requirements.
All sump pumps produce some amount of noise regardless of how loud or quiet they’re considered to be.
The most important factor, in this case, is the noise level.
As earlier mentioned, older pumps were much noisier than modern pumps.
By default, older models were made of PVC/ plastic while the new designs are constructed from cast-iron material.
The major determinant of the loudness of a sump pump is the motor size. Big motors translate to more power and noise compared to smaller sized motors.
If you need to draw water from deep pits, you will need a powerful motor than can pump more gallons at such depths. In such a scenario, you can make the pump quieter using the techniques provided in the next section below.
However, if you need to discharge water from shallow pits, a smaller size pump motor will do just fine. You will have no noise problems.
The last thing you ever want to experience is your sump pump failing when you need it the most.
You don’t want to end up with flooded basements. That’s where longevity and reliability come in.
My most recommended pump is the Wayne WSS30VN Upgraded Combination 1/2 HP. It’s an established and trusted brand that you can rely on.
Sump Pump Type
There are two main types of sump pumps- pedestal and submersible pumps.
Submersible pumps are submerged inside the sump pit, and this makes them less accessible and quieter.
On the other hand, pedestal pumps have above the ground motor and noisier and more obtrusive.
It’s important to ensure that the pump you buy is compatible with modern innovative technology.
For example, you’ll find that some pumps can connect to PumpSpy PSO1000 Wi-Fi Sump Pump Smart Outlet.
This is a tiny gadget that makes your sump pump Wi-Fi compatible to help you monitor every single activity down there. The gadget can send emails, text messages, and app alerts to your smartphone, tablet, and computer.
The construction will determine how long it will last. As aforementioned, cast iron pumps are a lot quieter than plastic/ PVC constructed pumps. They are also resistant to abrasion
On the other hand, PVC/thermoplastic materials won’t rust. They are also lightweight.
Stainless steel is prone to rust and heavier than plastic. Fortunately, they are rust-resistant compared to cast iron.
Overall, cast-iron is a great option- although prone to rusting, you can always apply an epoxy coating.
Most of the pumps in this guide are designed to be plugged into your home power supply.
In most cases, this is adequate.
But what would you do when the power goes off? Would you like a scene of the underground lake in your basement?
For this reason, it’s important to get a sump pump with a battery backup option. A perfect example in this guide is the Wayne WSS30VN Upgraded Combination 1/2 HP.
Quiet A Sump Pump in Simple DIY Simple Fixes
Is your sump pump making weird noises and don’t know how to fix it? Well, there are different reasons why your sump pit pump is making noise.
To fix the noise problem, you’ll first need to understand the type of noise because they require different approaches.
The vibrations often happen when the discharge pipe is in contact with the pump basin or when it hits a nearby wall.
To fix this problem, wrap the pipe where it meets the basin, wall, or floor with foam insulation. You can also line it up with rubber grommets.
If you have a noisy motor, you may need to lubricate it or upgrade it to cast iron type.
You can also try a submersible pump or cover the place over it to keep the motor noise muffled instead of resonating throughout the room.
Clanging and gurgling noises
Apply similar fixes as you did with vibrations in case you hear clanging.
Gurgling noises occur when water moves down the discharge pipe after the pumping cycle. To solve this problem, upgrade the standard valve with the spring valve to allow water to move more evenly through the plumbing.
Alternatively, adjust the pump switch to prevent the pump from emptying water completely out of the basin.
In this case, the pump produces similar sounds as a person sucking liquid through a straw. To fix this problem, adjust the pump to make sure that it always has a few inches of water in it.
Regular maintenance should help solve slurping noises.
