Sump pump check valves prevent water from returning up the discharge pipe when your sump pump is turned off, helping keep your pump from running continuously and wearing out prematurely.
Home improvement stores carry a range of check valve styles and types. Some feature PVC couplings, while others feature metal clamps.
Check Valve Types
Sump pump check valves are essential in stopping a pump from pumping the same volume of water twice, which could cause its motor to burn out prematurely. Installing a check valve not only reduces how long your pump runs but also saves you on electricity costs.
Different check valves come in both spring loaded and swing (flapper) style varieties. A spring loaded check valve is more acoustically friendly than its flapper counterpart, plus it closes faster so less force is needed to open it.
The spring-loaded type of check valve is more effective at stopping water from backing up through the discharge pipe and into your basement, while also allowing your sump pump to run more efficiently and effectively.
Another advantage of a spring-loaded check valve is that no air release hole needs to be drilled into its body, saving installation personnel time from having to do extra work.
Strong Plastic (PVC)
Strong plastic check valves can withstand high water pressure and are unaffected by chemicals found in groundwater. They come with flappers or gates for added convenience.
Cast Iron
Cast iron is an extremely durable material, capable of withstanding high water pressure. Plus, it lacks chemicals and isn’t susceptible to corrosion.
These check valves are commonly found in sewage systems and other areas with high water pressure. They come in various sizes to suit different applications.
A check valve is an integral component of any sump pump system. When installed by a certified Basement Systems dealer, your pump comes equipped with this valve and will be thoroughly inspected for leaks or damage before installation. If the sound of your sump pump making any noises like thumping, grinding or gurgling sounds indicates a malfunctioning check valve; you can test this by pouring water into the pit and listening to its internal flap open and close; if not working correctly, replacement of this check valve is necessary.
Check Valve Installation
The check valve is an essential element of any sump pump system. It prevents water from running back down the discharge pipe when the pump is turned off, thus avoiding water hammer, which is a leading cause of mechanical failure.
When installing a check valve, it is essential to make sure all parts fit together securely. To do this, apply cement over any area where couplings overlap pipes so they snap together securely.
Before you begin, make sure your sump pump and drainage pipe are approximately the same size. If in doubt, cut a small piece of pipe near where it emerges from the pit where the pump sits to get an idea of which size to purchase.
Additionally, you will need a pair of PVC couplings and adapters to connect the drainage pipe to the check valve. Many of these fittings can be found online or at home improvement stores.
Once you have all of your materials, it’s time to cut the drain pipe and start installing. It is easiest if you can access the vertical side of the pipe, but either can also be done.
Measure the diameter of a drainage pipe at least twice to guarantee it’s at least as wide as your valve selection. Additionally, measure its length from one end of the pipe to the base of the pump’s spout.
If the length is too long, you’ll need to trim it before proceeding. After that, spread cement over the pipe and start gluing it together.
Be cautious not to cut too close to the pump’s spout, as this could restrict water flow down the drainage pipe. Test each fitting by taking out some water and verifying that all parts fit securely together.
Once the valve and all its parts are installed, plugging it into the spout emerging from your sump pump should be straightforward. However, for added assurance it would be beneficial if someone else did this step for you so they can verify fitment.
Check Valve Parts
Sump pump check valves are essential for homes that have a sump pit or crawl space. They prevent water from returning to the pit after the pump shuts off, avoiding short cycling of the motor and extending its life expectancy.
When selecting a check valve for your application, there are various types available on the market. These valves are designed to handle specific fluid pressures and flow rates as well as temperature ranges; additionally, they are rated for working pressure and media pressure ratings.
These valves are constructed from steel and come in various sizes and configurations. Some have a flanged end while others are threaded. They’re widely used for sewage, water treatment and wastewater applications.
Some types of check valves are more durable than others. Some are built to withstand high pressures and offer a long lifespan, while others are lightweight for easy transport and installation.
Most check valves consist of a body and disc. The disc moves in an arc at right angles to the flow of fluid, held in place by a spring and retained by its retainer.
Another type of check valve is a ball check valve. These are intended for horizontal or vertical piping runs and perform well due to being less susceptible to turbulence or flow interference.
These valves are easy to use and don’t need much upkeep. They’re suitable for small to medium piping systems, and can be installed in several ways.
For instance, they can be mounted in a compression union mount without cutting pipe and need no messy glue to set before use or testing.
They make ideal battery backup pumps due to their ease of opening. Although a bit pricey, these extra benefits make the investment worthwhile in the long run.
Check Valve Replacement
One of the most essential components of any sump pump system is the check valve. This small piece of equipment prevents water from backing up into your pit when your pump shuts off, helping ensure that your basement doesn’t flood when power goes out.
This device is usually situated on the discharge line that runs from your sump pump to the outside of your house. It works by stopping water flow from entering into your house, avoiding flooding in the basement and damaging its foundation.
The check valve is typically constructed out of plastic and may include a hinged flapper. Over time, minerals can corrode or destroy both components, so it’s wise to replace them with more reliable models for increased longevity.
As with any plumbing project, it’s best to enlist the assistance of a certified professional. A certified plumber will know all the intricacies of this type of job and how to deal with various materials.
A plumber specializing in home plumbing can advise you on the most efficient way to install your check valve on your sump pump, as well as other essential components like the lid and flapper. Doing so can prevent costly repairs in the future and save both time and money.
Professional sump pump installers will offer you a free estimate and inspection for your home’s waterproofing requirements. This includes an in-depth demonstration of the check valve function as well as an exhaustive check of all parts involved in waterproofing – including nozzles and pits – plus they’ll suggest the most efficient way to utilize this new system in order to keep your residence dry and healthy.
