Various brands are producing the check valve because of its benefits. This makes it essential to find the best check valve for sump pump. The one you should choose should match your budget and have more features.
Sump pumps work with check valves that allow water to flow only in one direction, and this is why the water from deep in the pool is pushed out without it flowing back in. Therefore, the pump is a vital component of running a pool’s circulation system, especially true when draining out the water to clean it or to maintain it. You might have problems with your sump pump if you do not have a suitable sump pump check valve.
Basics of Sump Pump Check Valve
It is essential that you have a sump pump installed if you want to prevent water from flooding your basement or crawl space. These systems collect water from the lowest points and pump it into the sewer or out into the yard. But what prevents the water from re-entering the basin once the water has been turned off? That is when the best sump pump valve comes into play.
Sump pumps of the highest quality are surprisingly powerful for their size, yet this doesn’t keep water in drainage lines from flowing backward when the pump is turned off or when the power goes out. A check valve connects your drain lines to your pump and can prevent water damage and extend the life of the pump.
A sump pump check valve keeps water from entering the sump pump from the outside. Usually, after operating a sump pump and removing excess water, the user will turn off the pump after a certain period of time. As a result of the backflow and heavy pressure, water may be coming back. Water passes through the check valve in one direction only. When the valve closes, the path is blocked, and the basin stays dry.
The following are the steps to install a sump pump check valve:
- Make sure that you have a suitable and compatible valve in the right size (1-1/4 or 1-1/2), with the correct coupling (slip or threaded).
- If you are unsure about which type of check valve to pick, it is recommended to take a sample of the pipe to the hardware store so you can experiment with them. That way, you can buy the correct check valve.
- Before beginning the installation, make sure that all the tools are available after you have purchased the check valve. In the bare minimum, you will need a tape measure, a pipe cutter, a pipe cleaner, a utility knife, and PVC cement or glue, as well as a glue applicator.
- Be careful not to wet yourself or your tools during installation by turning off the sump pump before starting.
- Locate the discharge pipe and determine where the valve should be installed after turning off the pump. This should usually be installed in close proximity to the pump so that once it is turned off, there isn’t much water trapped between the two.
- Once you have established the best position for the check valve, you should cut the pipe at the same long-distance as the check valve to make sure the valve fits perfectly.
- Pipe cleaners can be used to clean the pipe’s edges once it has been filed. Next, place the valve into the discharge pipe, ensuring it fits properly. Check that it fits perfectly on both ends, so remove the valve. Then, apply glue or PVC cement with the applicator to the discharge pipe, then fit the valve back in and let it set.
- Once the cement has dried, run the pump to test the valve. Check for leaks, then turn off the pump and verify that the water isn’t flowing back.
Check Valve for Sump Pump Buying Guide
It can be confusing when it comes to plumbing equipment, especially when there are additional valves. Check valves are recommended for everyone’s system so that water doesn’t flow back into their sump pit when the pump is turned off. The purchase of an extra valve might seem unnecessary, but a few extra dollars can save the life of your pump.
You may have difficulty finding the best check valve. You should do much research before purchasing. Don’t forget to do your research, or you may wind up having to shop for a new valve and trying to dry out your basement! Read our in-depth buyers guide to find the best fitting check valve to replace your old one.
Drainage lines and sump pumps are not all the same size. For the right discharge pipe size, check your pump’s owner’s manual and measure your drain lines. Choosing the wrong valve will result in you not being able to connect the valve to the pump or the lines and in having to buy another. Be sure to do your research before you buy. There are people who will try to attach the wrong size with stainless steel clamps, but this “quick fix” leaves your basement vulnerable to flooding.
PSI and Head Height
Choosing a new check valve requires consideration of PSI and head height. Each home and sump pump has its own flow rate. Your check valve may leak if the pump is too powerful.
Ensure you know what your head height is as well as how far the pump is from the end of your lines to ensure you don’t overpower or underpower your system.
Sump pumps must have a check valve that can withstand heavy loads and high pressure. A durable valve is therefore necessary. The product can be made durable by using durable materials. Usually, ABS plastic and metal, such as brass or stainless steel, are used to construct the valves. It’s hard to tell which is better; metal lasts longer, plastic is easier to install. Also, keep in mind that metals like brass and copper are more prone to corrosion than plastics.
Check valve bodies made of PVC plastic or ABS are known for being durable and long-lasting. Check if the clamps on the valve are stainless steel, if there are any. Also, find out how much pressure it can withstand.
Check valves are fundamentally the same, even though their styles may vary. In some cases, check valves are designed to attach to a sump pump via a threaded connection, and others are specifically designed for slip-x-slip connections. Be sure to check the style of the check valve that matches the sump pump you currently use before ordering one. However, threaded styles are more suitable for metal piping, such as galvanized iron or steel pipes.
Each sump pump valve has a different diameter. So, find out the diameter of the pipe that fits inside the sump pump before you look for a new check valve. Choose a check valve that matches that diameter. However, most sump pump pipes are 1.5 inches in diameter. Choose the right check valve to match the size.
When the sump pump is working, some check valves can make a lot of noise. The noise can be highly annoying. Choosing a check valve with less noise will make you more comfortable.

The ABS plastic body has a Nitril-Bruna N Seal inside to prevent water from flooding back into the pit. It can handle pressures up to 11 PSI, but if the distance to your drain is long, you may need to hook up multiple check valves and hoses.

|Dimensions||3 x 3 x 11.4 inches|
With its extremely quiet design, AY McDonald’s 4424-100 is made to eliminate water hammer, which usually occurs once the pumping cycle has finished. Apart from that, the valve closing mechanisms inside of the valve are tested for leaks under pressure, which means that it is reliable.
The body of this product is made entirely from plastic, with a one-piece housing that eliminates the need for gaskets that could fail over time. The unit features 1.5-inch female sockets that can be easily mounted over PVC, steel, or copper pipes of similar size, and each socket has a stainless steel clamp that assists with tightening the joint.
The only issue is that this valve is extremely pricey.
6. Little Giant 599059
|Dimensions||8.7 x 6.3 x 4.2 inches|
|Installation||In horizontal or vertical lines|

7. Wayne Pumps 66005
|Dimensions||3 x 3 x 8.5 inches|

Even though the valve may not seem like much, once the pump is turned off, it can prevent water from returning to the pump pit. The backflow of water causes permanent damage to a pump and leaves water in the basin. Having so many adapters available, it is easy to choose the right size for your pipes and to attach the connectors and clamps.
8. Zoeller 30-0043
|Dimensions||1 x 1 x 1 inch|
|Installation||In horizontal or vertical lines|

The noisy water hammering is one of the most common problems owners of check valves report. By using a 1/2 lb inner spring, this problem is resolved while still allowing water to flow only out. Furthermore, it prevents the pipes from shaking, thereby preventing plumbing noise in powerful systems.
9. Smith-Cooper International CV30L
|Dimensions||2.9 x 1.6 x 1.5 inches|
