Buying Guide to Choose the Right Sump Pump Check Valves

If you don’t know which valve actually fits your sump pit requirements, check out this buying guide for the best sump pump check valve. This guide discusses key features like the pressure rating, connection types, working capacity, and build quality of the sump pump.

Size

The size of the value is actually the discharge size of its outlet. The discharge size of the valve should be the same as the discharge size of the pump and drainage pipes. If you are not sure about what discharge size you need, seek help from a plumbing professional. You may find some temporary solution to fix the wrong size valve with the sump pump, but it will put your basements and pump system at a big risk.

PSI, Head Height, and flow rate rating for the valve are other features you need to consider. Every sump pump works at specific water pressure and flow rate. If you connect an underpowered valve with a powerful pump, it results in leakage issues. Similarly connecting a powerful valve with a high-pressure rating to a weak pump can damage the sump pump due to strong action. The PSI rating and flow rate handling should be in line with the specification of your sump pump.

Sump pump check valve height and the pump’s distance from the end of transmission lines will decide how much power you need. For long transmission, you need powerful systems. Knowing the right head height will help you choose a well-balanced and perfect valve for your sump pit.

Build Quality

The service life of the pump largely depends on the build quality of its housing. ABS plastic and metal are two common materials used to craft the check valve bodies. ABS plastic is lightweight and offers effortless installation. However, its impact and temperature resistance are limited as compared to a metallic housing. Steel and brass bodies offer a long service life but the installation process is a little complex. Also, metal bodies are more prone to corrosion than their plastic counterparts.

Ease Of Installation and Fit

Check valves are available in various designs and fittings. You can find various one-size-fits-all or universal-fit designs for effortless installation. Advanced checks valves support a wide range of adapter sizes and connectors making them suitable for almost all sump pumps.

FAQs about Sump Pump Check Valves

How do I choose a sump pump check valve?

How often should a sump pump check valve be replaced?

The average life of a sump pump check valve varies between 5-7 years. However, the service life of the check valve also depends on the intensity of the operation. In low-lying areas, the valves tend to cycle more frequently and also wear out quickly.
