If your system has an existing check valve, it’s a good idea to replace it when you install a new pump. All sump pumps installed by an authorized Basement Systems dealer are tested and approved by the manufacturer.

Does a submersible well pump need a check valve?
Check valves permit water flow only in one direction, and are required on all submersible pump installations. A pressure relief valve (PRV) permits water to flow in both directions. PRV is located at the bottom of the tank and is connected to the main pressure control valve. It is designed to allow the flow of water through the system to be reduced to a level below the level at which it would normally flow.
This reduces the amount of pressure that is required to maintain pressure in a well. In the event of a failure of one of these valves, water will flow back up the pipe and cause a loss of well pressure. If the valves are not properly maintained, they can fail, causing a pressure drop that can lead to an uncontrolled well collapse.
How far should a check valve be from a sump pump?
Unless the owner’s manual states otherwise, the best height is two to three feet off the top of the pit. When your check valve is in the lower position, your motor doesn’t have to work as hard. The weight of the water in the pump will make it easier to open.
If you are using a pump that has a built-in air compressor, you will need to adjust the height of your pump to allow for the air to flow through the compressor. If you have a manual pump, it is recommended that you use a height adjustment tool to make sure you get the correct height. You can find these tools at most auto parts stores.
They are usually called a “height adjuster” or “adjuster.” They can be found under the hood of a car, truck, or SUV. These tools will allow you to raise or lower the water level in your water pump by a certain amount. For example, if you want to pump water to a depth of 3 feet, then you would adjust your height to 3.5 feet.
Does a submersible pump have a built in check valve?
Many submersible pumps come with a built-in check valve, however if this is not the case, a line check valve should be installed in the discharge line within 25 feet of the pump and below the water line.
If you are using a pump that has an automatic shut-off feature, make sure that it is set to automatically shut off when the pressure drops below a certain level. If you have a pressure gauge, you can use it to check the flow rate of your pump.
You can also use a water level gauge to see how much water is left in your tank.
Are check valves necessary?
Many different applications use check valves. They are often placed on the outlet side of a pump to protect it from backflow. A check valve is a device that allows a water pump to be turned on and off by turning a dial. The dial is connected to a valve, which is attached to the water supply line.
When the valve opens, water is pumped into the tank. If the dial does not open, then water cannot be pumped out of the system. Check valves can also be used to prevent water from flowing into a tank when it is not needed.
Where should a check valve be installed?
In horizontal or vertical piping runs, the check valve can be installed. It is not a good idea to mount for vertical installations.
The flow rate of the system must be at least 1,000 cfm per minute (cfm/min) for the first 30 minutes of operation, and must not exceed 2,500 cf m/minute for any period of time after that.
The system is designed to operate at a maximum flow of 3,200 cf ml/hr (3,400 cf/m3) during periods of high demand, such as during a power outage, or when the temperature is above 60°F (15°C).
Is it OK to have 2 check valves on a sump pump?
So with two check valves in parallel, you protect against the stuck-closed scenario (as it is unlikely that both check valves will fail in the same manner), but are actually more likely to have a stuck-open fault, since if either check valve fails open the discharge water will flow into the other valve.
In the case of a single-check-valve system, if one of the valves fails, the flow of water through the system will be stopped, and you will have to start over from the beginning. In this case, it may be necessary to replace the valve(s) in order to prevent the problem from recurring.
Does a check valve go before or after a pump?
An in-line ball check valve is one of the common check valve types included in a foot valve. They are usually installed at the end of a pump suction line of a water well, fuel tank, or any other application.
(SAPVs) are the most common type of valve installed in water wells. These valves are designed to allow water to flow into the well at a constant rate, without the need for a compressor or other mechanical device.
