Best under sink drain pump 2023-Complete Buying Guide

Under sink drain pumps are commonly found in laundry and utility rooms, wet bars, kitchens, and bathrooms. They are used to pump gray water, or wastewater from fixtures such as dishwashers, garburators, faucets, showers, toilets and more. These pumps help fight against backed-up drains caused by heavy rainfall and other water-related issues.

Under sink drain pumps are handy for moving wastewater from one area to another without having to manually move the wastewater around. Not all wastewater needs to be moved to a sewage system for treatment; draining it away into a septic tank or collection area instead can be much more efficient. With that being said, when it comes time to buy a new under sink drain pump for your home or business there are several key factors that you should consider in order to get the most out of your investment.

The first type of pump you should consider is the Submersible pump which is designed specifically for under sink applications where it can be permanently installed in moisture-rich areas. This type of pump is built with an enclosed motor section so it can remain deeply submerged underwater while still running effectively and efficiently. Another major benefits of submersible pumps is that they are typically larger than other types of under sink drain pumps on the market allowing them to move large amounts of water quickly.

The next type of electric under sink drain pump available is a multipurpose model which is portable and can be used in almost any location thanks to its compact size and lightweight design. These multipurpose models usually come with adjustable speed settings so that you can tailor the output power according to your needs depending on what type of waste water needs pumping away at any given time. Many models also come with safety features such as temperature sensors so if the unit gets too hot during operation it will automatically shut off before causing any kind damage or harm to itself or surrounding areas/items.

Benefits of Installing an Under Sink Drain Pump

Installing an under sink drain pump can provide numerous benefits in your home or office. These pumps are highly efficient, allowing them to quickly and effectively remove wastewater from sinks and showers so that it cannot become a health risk. With one of these units installed, you can be sure that the water is being delivered in a safe, sanitary manner.

In addition to this, these pumps also help conserve water by preventing sink and shower drains from becoming clogged with debris over time. When water is allowed to flow freely through the pipes, there is less likelihood of having a backed-up drain or overflowing tank. This means you will not have to spend time and money cleaning up after plumbing trouble caused by a clogged drain line.

Investing in an under sink drain pump can also help improve the air quality in your home or office due to the fact that fewer contaminants will be allowed entry into the draining system as it takes away wastes from sinks and showers. These pumps are designed with powerful filters that lend themselves to separating dirt particles from the expelled water so that it does not become contaminated during its journey outside of your residence.

Factors to Consider When Buying an Under Sink Drain Pump

When purchasing an under sink drain pump, there are a few important factors to consider:

  • Type of pump. There are multiple kinds of pumps available in the market today such as submersible, condensate, and effluent pumps. Each one is designed for use in different situations, so it’s important to choose the right type of pump for the job.
  • Power supply. You should make sure you find a pump that has enough power to move water around your home effectively without needing too much energy or creating too much noise that could disrupt your day-to-day activities. Additionally, you may want to consider more advanced pumps that use alternating current instead of direct current for more efficiency and reduced power consumption.
  • Space. If space is limited due to fitting challenges or if you simply can’t accommodate large equipment under your sink then a slimline style pump may be the best option for you. There are also certain types of pits and other storage units designed specifically for this purpose which can increase storage capacity and make installation easier when space is tight.

Types of Under Sink Drain Pumps

When purchasing an under sink drain pump, it is important to understand the different types available so you can make a well informed decision. There are essentially two types of pumps available; macerator pumps and sump pumps.

Macerator Pumps are devices that grind wastewater into small particles for easier processing and disposal. These units typically feature blades that shred or mince waste before pumping it out of your home through pipes that lead to a sewer line, allowing you to avoid costly repairs associated with damaged pipe lines. Macerator pumps are usually used when dealing with large objects like food items and other particulates that might clog up your drainage system, because they can relatively easily break down these items into manageable size.

Sump Pumps are designed to remove water from basements or crawlspaces in residences where flooding may become an issue. Sump pumps work best when installed in sump pits filled with gravel or aggregate as they pump water up to the desired level before discharging it outside through pipes leading away from the home’s foundation. While most sump pumps are electric, some operate using battery-powered motors that require less maintenance and upkeep than electric versions but still provide reliable performance for areas prone to flooding.

The type of drain pump you should choose ultimately depends on the application and specific requirements needed for proper installation and operation in your residence or business facility. For example, if you experience frequent flooding or food items tend to clog up your plumbing system, then a macerator pump would be better suited for this purpose versus a sump pump. Similarly, If there is no fear of flooding then a sump pump would be more appropriate for draining away excess liquid build-up due its higher pressure capabilities compared to its counterpart specifically designed for grinding fibrous materials like food waste particles.

Benefits of Different Types of Under Sink Drain Pumps

Under sink drain pumps come in a variety of styles and are useful in many ways. Depending on the situation, different pumps may offer a few benefits over the others or work better for certain tasks. Here are the major benefits of three types of under sink drain pumps that consumers should consider before making a purchase:

  • Submersible pumps: Submersible pumps can be submerged in water and are typically used to pump clear water such as domestic and agricultural runoff. They have several advantages because they’re efficient and easy to install. They’re also inexpensive, require very little maintenance, and consume lower energy than normal electric drainage pumps.
  • Pressurized sump: Pressurized sump can remove wastewater from a deeper level than submersible pumps. These type of under sink drain pumps increase pressure through their built-in pressurizer tank to ensure that wastewater is pushed uphill even if it has sediment levels or is contaminated with microorganisms in it. This makes them ideal for higher altitude applications where pumping uphill is required.
  • Sewage ejection system: Sewage ejection systems use two separate tanks with an airlock in between them, allowing them to reduce any potential odor from entering your home while efficiently taking waste out of the house using very high pressures. This type of pump is best suited for larger households that produce more wastewater than average, as they have large capacity tanks and require less frequent emptying cycles compared to other systems.

Top under Sink Drain Pump Brands in 2023

When searching for the right under sink drain pump in 2023, it is important to consider the brand options available. The brands that offer these pumps provide a wide range of products, from budget models to more complex and powerful options.

Installation Tips for Under Sink Drain Pumps

Under sink drain pumps are a convenient and efficient way to pump wastewater away from plumbing fixtures when gravity does not adequately move it. This type of pump is commonly used in bathrooms and kitchens, and it is designed to fit into a small space under the sink or in a cabinet. In order for it to work properly, there are several installation tips that should be followed.

  1. Check the specific instructions listed by the manufacturer, as they will vary depending on the type of pump being installed.
  2. Measure twice before cutting any pipes and make sure to use a hacksaw (or other appropriate tool) instead of scissors or wire cutters.
  3. Place the unit securely on an even surface and level it before wiring it up. This is best done by an electrician or someone with electrical experience – incorrect wiring could create a fire hazard!
  4. After all connections have been made, test-run the unit to make sure that no leaks exist.

To ensure efficient operation of your under sink drain pump unit over time, regularly inspect for signs of wear or damage such as rusting pipes or loose wiring connections. If any issues arise during testing or general inspection of your unit, contact a professional service technician for assistance if necessary before continuing operation. With proper installation, maintenance and repair methods, you can ensure your under sink drain pump is operating safely and reliably in your home for years to come!


When selecting a sump pump for your home, it’s important to consider all the factors listed above. The right pump will meet your needs and make drainage easier.

Depending on your budget, you can select a smaller pump that fits in an open or closed basin, or a larger one with higher capacity for larger basins. Always make sure to check the manufacturer’s specifications before making any purchase. With the right sump pump and proper maintenance, you will be able to effectively control water buildup in your under sink for years to come.


How does a sink drain pump work?

A sink drain pump works by pumping water from the sink basin up to the main drain line. It is typically used in situations where the sink is located below the level of the main sewer or septic line. The pump uses an impeller to create suction, drawing water into the pump, then it uses a motor to pressurize the water and force it up to the main drain line.

Why is my sink pump not working?

A sink pump may not be working due to a variety of reasons, such as a clogged impeller, a failed motor, or a power issue. It’s also possible that the discharge pipe is clogged or the switch is not functioning properly.

What is a drain pump?

A drain pump is a device that is used to pump water from a lower elevation to a higher elevation. It is commonly used in sinks, washing machines and dishwashers to pump water into the main drain line.

Does a drain pump need a vent?

Drain pumps typically do not need a vent, as they are designed to pump water out of the basin and into the main drain line.

How long do sink pumps last?

The lifespan of a sink pump can vary depending on usage, but most pumps have an expected lifespan of around 3-5 years.

How much does a sump pump cost?

The cost of a sump pump can vary depending on the type and size of the pump, but a basic submersible sump pump can cost around $100 to $200.

How do you clean under sink pump?

To clean under a sink pump, you should first turn off the power to the pump. Then, you can remove the pump cover and impeller to check for any clogs. Clean the impeller and the surrounding area, and check for any debris that may be blocking the discharge pipe. Finally, reassemble the pump and turn the power back on.

How do you drain without a pump?

Without a pump, you can use gravity to drain the basin by connecting the sink to a drainage pipe that is located at a lower elevation than the sink.

Which pump is used for drainage?

A sump pump is commonly used for drainage of water in basements and crawl spaces.

How do I know if my drain pump is working?

You can check if the drain pump is working by running water in the sink and observing if the water is being pumped out. You can also listen for the sound of the motor running, and check for any error codes or indicator lights on the pump control unit.
