Should the check valve be horizontal or vertical to the sump pump? Check your local municipality's requirements. But typically you want it vertical about 2 feet up from the pump.
Also, how far should check valve be from sump pump?
Should the check valve be horizontal or vertical to the sump pump? Check your local municipality's requirements. But typically you want it vertical about 2 feet up from the pump.
One may also ask, where should a check valve be installed? Check valve can be installed in horizontal or vertical piping runs, with the flow running upward. Mounting for vertical installations is critical.
Similarly, it is asked, is a check valve required on a sump pump?
Sump pump check valves are an important part of any sump pump system. Installed in the discharge pipe leaving your sump pump, the sump check valve prevents your pump from having to re-pump water it has already discharged.
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.
What is the best check valve for sump pump?

How long does a sump pump check valve last?
Can I put two check valves on 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.
Should there be water in my sump pump pit?
2 Answers. The water should not be that high in the sump. It should be down to around the 2-3″ level inside. First, find the float switch which should turn your pump on when the water gets deep enough (it should be a ball floating in the water somewhere, maybe under the drain pipes).
Can a sump pump check valve be installed horizontally?
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).
Is a check valve necessary?
Check valves are designed to permit water to flow in one direction and are a requirement on all submersible pump installations. Their job is to prevent water in the column above the pump and in the pressure tank from draining back into the well when the pump shuts off.
How often should a check valve be replaced?
How Often Should You Repair or Replace Pressure Relief Valves?
- Testing every 12 months.
- Repair every three to five years.
What is a check valve used for?
Simply put, a check valve allows flow in one direction and automatically prevents back flow (reverse flow) when fluid in the line reverses direction. They are one of the few self-automated valves that do not require assistance to open and close.
Why is my sump pump check valve leaking?
On some models the check valve prevents the backwash of pumped out water back into the sump pit. Over time the valve can develop leaks either due to loose connections to the pipes or a failing internal valve.
Why is my sump pump spraying water?
Discharge Pipe Spraying Water
If the discharge pipe is spraying water out the end it is a sign that the sump pump is working hard draining ground water. On the other hand if the leak is on the inside you will need to reseal the pipe connection in order to prevent a basement flood.
How do I know if my sump pump is working?
The first way to test the sump pump is to trace the two electrical cords of the sump pump. The pump cord plugs into the back of the float cord plug. Both cords should be unplugged and only the pump cord should be plugged into the outlet. If a humming sound is heard when turning on the pump, the pump works.
Can a check valve get stuck closed?
One, check valves are prone to jamming in the open position, thereby becoming an uncheck valve of sorts. Two, they are prone to jamming in the closed position, preventing water flow in any direction. If the check valve is stuck open, the pump runs and pumps just fine; however, it won't prevent backflow or flooding.
Can check valve be installed vertically?
Check valve can be installed in horizontal or vertical piping runs, with the flow running upward. Mounting for vertical installations is critical.
Does a shallow well need a check valve?
Because shallow–well jet pumps use water to draw water, they generally need to be primed–filled with water–before they'll work. To keep water in the pump and plumbing system from flowing back down into the well, a 1-way check valve is installed in the feed line to the pump.
What is the symbol for a check valve?
An arrow or the symbol for any type of check valve (a fluidic/pneumatic logic symbol) on the outside of the body indicates flow direction.
How do you check a check valve?
Place a hand on the valve and put your ear next to the valve if the temperature of the fluid will allow you to do so safely. Any sound of fluid running indicates a leak. A properly working valve will only render a small ”click” noise, indicating that the check valve is closing and blocking water from running backwards.
Can a sump pump check valve go bad?
Yes, your sump pump discharge pipe can freeze and you'll have sump pump check valve failure. No air relief hole or clogged sump pump weep hole in the discharge line. You should always have a sump pump weep hole in your discharge line to prevent damage to your pump and check valve.
What is silent check valve?
Silent check valves, also known as non-slam check valves and spring-assisted check valves reduce or eliminate water hammer and its effects. Water hammer refers to the high-pressure shock waves that occur when the flow of fluid abruptly stops (due to pump shut down or a valve disc quickly closing) in a piping system.
What does a check valve do on a sump pump?
A check valve on the discharge line keeps water in the pipe from flowing back into the sump pit when the pump switches off. A check valve is sometimes referred to as a “one-way” valve because it allows water (or any liquid) to move in one direction only.
