Where should a sump pump check valve be installed?
The most suitable location for a sump pump check valve is close to the floor level to minimize the volume of water that drains back at the end of each pumping cycle and it is a convenient location for easy servicing or replacement of the valve.
Is a check valve required on a sump pump?
Without a sump pump check valve in place, all the water in the discharge pipe empties back into the sump pump pit liner. This causes the water level in the liner to rise. Higher water levels in the sump pit liner causes the pump to run more often, increasing energy costs.
What height should a sump pump check valve be installed?
Best height ( unless owner’s manual states otherwise) is two to three feet off of the top of the sump pit. This way your sump pump motor doesn’t have to work as hard as when your check valve is in lower position. It will open easier due to the reduced weight of water above it.
Should sump pump check valve be horizontal or vertical?
They can be installed in vertical or horizontal systems, depending on the type of liquid that you are removing. If you are pumping out solid or semi-solids, the check valve must be installed horizontally (up to a 45 degree angle). If you are putting in a check valve for a Sump vs.
Can you have 2 check valves on a sump pump?
The two check valves are NOT a problem. The problem is where the original one is. When the secondary pump operates its discharge will flow down through the other pump so all you will be doing is circulating the water.
Can a check valve be submerged?
Will the valve be installed in a submerged condition? If the valve is installed in a submerged condition, this means that there will always be back pressure on the valve.
Is a check valve necessary?
Do I need a check valve? A check valve is a valve that is used to prevent backflow in a piping system. Even if a pump does have a built-in check valve, we recommend that a check valve be installed in the discharge line within 25 feet of the pump and below the draw down level of the water supply.
How does a check valve work on a sump pump?
How a check valve works. A check valve on the discharge line keeps water in the pipe from flowing back into the sump pit when the pump switches off. The water that remains in the discharge pipe will fall back into the sump pit, raising the water level again so that pumping will need to resume.
Will a check valve work horizontally?
Check valve can be installed in horizontal or vertical piping runs, with the flow running upward. Mounting for vertical installations is critical.
Where should the weep hole be on a sump pump?
Your Weep Hole should be drilled between the discharge and check valve. The hole should be drilled downward at a 45 degree angle, pointing away from your pump but inside your pump pit. Make sure to disconnect your pump from the lines and place it in a place that is easy to drill.
Why is my sump pump check valve so loud?
Waste lines from a sewage ejector or sump pump use a check valve to stop wastewater from flowing back into the basin. When these valves shut, they can make a thud loud enough to be heard throughout the house. To quiet them, replace the old check valve with a “silent” or “soft close” check valve.
How do you install a check valve swing?
Here are the steps to install a swing check valve: Check Valve Size. Before you purchase your swing check valve, make sure that you know the size and style you need. Look Inside the Valve. Check the Edges. Confirm Placement of Valve. Attach Swing Check Valve onto Pipeline. Test the Valve.
Where should a sewer check valve be installed?
Sewer check valve or back water valves should always be installed on the street side of the house trap. Installing it in this correct manner ensures water overflow from a public sewer system has no opportunity to release into a property prior to the backwater valve closing and reducing the flow.
What happens when sump pump check valve fails?
When a check valve is not installed on your sump pump’s discharge line, a back flow of water can cause the pump impeller to rotate backwards and unscrew off the motor shaft. If this occurs, the motor in your sump pump will sound like it is running but it will not be pumping any water out the discharge line.
Is a double check valve the same as a backflow preventer?
A dual check backflow preventer is similar to a double check valve in operation. It has two independent spring-loaded check valves. However, dual check valves usually do not include shutoff valves, may or may not be equipped with test cocks or ports and is generally less reliable than a double check valve.
