Best Sump Pump Check Valves

Here is the list of the 8 best sump pump check valves that you can use to ensure proper operation of your sump pump system.

1. Superior Pump 99555 - Best for Multipurpose Applications

Superior Pump is one of the leading names in the plumbing industry. It has been in this business since the 70s and is known for delivering very high-quality plumbing products. That said, the 99555 check valve from the brand features a universal design and allows liquid to flow in one direction only.

There are quite a lot of things that we really liked about Superior Pump 99555. To begin with, it is made using ABS plastic, which makes it highly durable and sturdy. It features a universal fit, allowing it to work with multiple applications such as ABS fittings, PVC fittings, and barbed hoses, making it simple and easy to install.

Furthermore, you would be pleased to know that the interior of this check valve is made with Nitril-Bruna N seal, which prevents water from flooding back into the sump basin. Also, it can handle water pressure up to 11 PSI, which always helps in providing better drainage.

Apart from this, it weighs just a little over 7 ounces, making it very easy to carry. Overall, it is one of the most affordable sump check valves that you may not want to miss out on. 

We faced a very hard time finding any significant drawbacks of this check valve. However, we noticed that it does not fit with a garden hose, given the fact that the package says that it fits all. Other than this fitting issue, it does a great job.

Material: ABS Plastic | Size: Fits Any 1 1/4" or 1 1/2" NPT Male/Female Thread | Connection Type: National Pipe Tapered (Inlet), MNPT (Outlet) | Water Pressure Limit: 11 PSI

2. Campbell B00JFF205Y - Best for Quiet Environments

Next up, we have Campbell B00JFF205Y. Campbell is one of the most popular brands when it comes to delivering high-grade plumbing equipment. The B00JFF205Y check valve is a metal-made option from this brand, which is suitable for people looking to purchase a very quiet check valve.

We were thoroughly impressed with its noise production, for starters, which is much quieter than most options available on the market. It does not produce the much dreaded 'thud' sound. Plus, it takes only 15 minutes to install, which is pretty quick.

Made using polyvinyl chloride, Campbell B00JFF205Y works quite well with almost all types of sump pumps. It supports 150 PSI and can deal with water at a maximum temperature of 120 degrees. Sounds good, doesn't it? Well, that’s not all!

It is also one of the affordable options on this list, and since it is almost silent, it won't be a problem if it's set up near your bedroom. Apart from that, it can be installed horizontally as well as vertically, making it a flexible check valve option. 

Even though Campbell B00JFF205Y does a decent job in most aspects, it comes with a drawback. We noticed that it puts extra strain on the sump pump's motor, which decreases its speed. We really wish the manufacturers had done something about it.

3. Zoeller 30-0181 - Best for High-Temperature Applications

This brand holds a reputation for producing exceptionally high-grade products for its customers. And the Zoeller 30-0181 is one of the finest check valves from the brand that can easily complement your sump pump.

As a sump pump check valve from a brand that has been in the business since 1939, Zoeller 30-0181 exceeds our expectations. Featuring 1-1/2 slip x slip unions and a flapper that bends over the edges, it ensures high performance for your sump pumps.

Coming to its build quality, it is made using plastic and metal, enabling it to resist 4.3 PSI, pushing water up to 10-feet. Plus, it can withstand temperatures up to 130 degrees Fahrenheit.

Furthermore, it can easily fit with copper pipes, steel pipes, and ABS, allowing flexibility across a wide range of applications. Overall, this unit is one of the best-selling check valves on the market that makes the task of making water flow in one direction very simple. 

The Zoeller 30-0181 is undoubtedly one of the best options for check valves on the market. However, it may not be for those who are looking for quiet check valves as it is extremely noisy. Other than its loud noise, we do not have anything to complain about.

Wayne Pumps 66005-WYN does an exceptional job of preventing water from flowing back into the sump basin. Ergonomically designed, it comes in black color, giving it a very professional and sleek look. However, the best part about this product is that it makes very little noise.

Even though Wayne Pumps 66005-WYN checks most of the boxes yet it misses out on an important one. It does not come with proper instructions; we found out that only 1 rubber coupling was provided, whereas the instruction states that there should have been 2.

Material: PVC | Size: 1 1/2" Threaded Male End, 1 1/4" Outflow Shoulder End, 1 1/2" Shoulder End Adapter | Connection Type: Threaded (Inlet) | Water Pressure Limit: N/A

What drew our attention right from the very beginning was its build quality, featuring an ABS body; it makes it highly durable and sturdy. Even though it is mostly made using plastic, the fasteners and clamps are made of stainless steel.

The Jackel DJ-545 offers a lot, given its price point. However, installing it may not be the easiest of jobs. Wondering why? The fittings are on the smaller side; the pipe adapters included in the package were too tiny to work with a 1.5-inch pipe.

We were impressed with most of the features that Zoeller 30-0041 provides. Firstly, installing this is like taking a walk in the park, and the best part about it is that it is quieter than most check valves on this list. You can sleep peacefully at night without having to hear that thumping sound.

Even though it is made out of plastic, it can bear water pressure up to 50 PSI, making it extremely productive, and moreover, it can withstand temperatures up to 130 degrees Fahrenheit.

We consider the main highlight of this product is its build quality, made of ABS plastic, hence ensuring durability. It is easy to install, thanks to the easy-slip fit design, and it features a one-way flapper valve that helps prevent water from flowing back in horizontal lines.

Apart from this, it can work with 1-1/4" or 1-1/2", the two most popular sizes of IPS pipes. You can use it on the sump pump to make it more efficient. Featuring a sleek black body, this product is one of the most reasonably-priced options on the list.

Buying Guide for the Best Sump Pump Check Valve

We hope by now you have gone through the top 8 options of sump pump valve options, so were you able to make a decision?

We are pretty sure that you are still confused. Choosing the best option can be bewildering as there are a few other factors that need to be taken into consideration apart from the brand and the price.

On that note, we have provided this buyer's guide to help you select the best sump pump check valve. In this section, we have explained all the important factors that you need to know before making a buying decision. Keep reading.

  1. Build Quality

The build quality of a check valve is one of its most important features. Most check valves are made using ABS plastic or metals such as stainless steel or brass. Both metal and plastic are good.

Having said that, plastic valves are easier to install than metal ones; also, metal valves are prone to corrosion. On the other hand, however, metal valves are more durable and tend to last longer than plastic valves.

  1. Size

It is very important that you buy the right size of the check valve; otherwise, you won't be able to connect it to the sump pump or the drainage lines. We strongly advise conducting prior research before buying, checking all details carefully, and only then buying.

  1. PSI

Kindly ensure that you are familiar with the PSIs. If your sump pump waters at a different rate, then the check valve may not handle the pressure and lead to leaks. We recommend you know the maximum water pressure of the check valve before buying.

Can I replace my sump pump check valve on my own?

Yes, you can replace your sump pump check valve on your own. However, if you’re not comfortable with DIY plumbing, it’s best to seek help from a professional to avoid any potential damage to your sump pump system.

How do I install a sump pump check valve?

Installing a sump pump check valve involves placing it on the discharge pipe, above the sump pump. You’d need to cut the pipe to fit the valve, insert the valve and secure it with stainless steel hose clamps. It’s crucial to ensure the valve is situated in the correct direction to facilitate one-way flow.

Is there a specific orientation when installing a check valve?

It depends on the type of valve being used. Spring check valves can operate in any orientation, while swing check valves are sensitive to gravity and must be installed in the correct orientation.

How often should I replace my sump pump check valve?

Generally, it is recommended to replace your sump pump check valve every 5-7 years, or whenever you notice it’s not functioning correctly. Signs of a faulty valve may include unusual noises, continuous cycling of the pump, or water flowing back into the sump pit.


Installing a check valve on a sump pump is important to ensure that the water keeps flowing in a single direction. This prevents the sump basin from getting flooded and increases its longevity.

On that note, we have come to the end of our review-based guide. We hope by now you will be able to choose the best sump pump check valve.

Before winding things up, we would like to mention our top picks of sump pump check valves, so let us do a little recap. Superior Pump 99555 is the best overall. Campbell B00JFF205Y does not make much noise, while Zoeller 30-0181 is affordable and easy to install.

Now, we will take your leave.
