10 Best Check Valves For Sump Pumps of 2022


A sump pump is a lifesaver during the rainy season, keeping your basement or crawlspace dry and preventing flooding. But a sump pump is only as good as its check valve—the component that prevents water from flowing back into the pit after the pump has done its job.

In this blog post, we’ll give you a crash course on check valves for sump pumps: what features to look for, the pros and cons of different types of valves, why shopping online is your best bet, where to find reviews, how much you can expect to spend, and common problems you might encounter. By the end of this post, you’ll know exactly what to look for when shopping for a new check valve!

What Is a Check Valve?

A check valve is a one-way valve that allows water to flow in only one direction. It’s installed in line with the discharge pipe of the sump pump, and it’s crucial for preventing water from flowing back into the pit after the pump has turned off.

There are three main types of check valves: flapper valves, spring-loaded valves, and ball valves. Each type has its own pros and cons (which we’ll get into in more detail later), so it’s important to choose the right type of valve for your particular needs.

Why Shop Online?

When it comes to shopping for a new check valve, we highly recommend buying online. That’s because online retailers typically have a much wider selection than brick-and-mortar stores—which means you’re more likely to find exactly what you’re looking for. In addition, shopping online makes it easy to compare prices from different retailers so that you can be sure you’re getting the best deal possible. Not to mention, you’ll save yourself a trip to the hardware store!

How Much Should You Expect to Spend?

Check valves range in price from $10-$50 depending on the type of valve and the materials it’s made from. If you’re on a tight budget, we recommend opting for a plastic valve—they may not be as durable as their metal counterparts, but they’re much more affordable. Just be sure to choose a high-quality plastic that won’t crack or break under pressure.

What Are the Most Common Problems You Might Encounter?

One common problem with check valves is that they can become clogged with debris over time, which prevents them from working properly. This is usually due to improper installation—if the valve isn’t installed level with the discharge pipe, sediment can accumulate in the valve and prevent it from opening and closing correctly. Another common issue is improper sizing—if the valve is too small for your discharge pipe, water will leak around it instead of going through it. Be sure to measure your discharge pipe before ordering a new valve so that you can choose one with the proper dimensions.
