How far should a check valve be from a pump?
In submersible pump applications, the first check valve should be installed directly on the discharge head of the pump or maximum one pipe length (20 feet) above pump. Water pumped and flowing through a piping system has a certain amount of energy (weight x velocity).
Why is a check valve installed on the discharge side of a pump?
A check valve will be used commonly on the discharge of the pump to prevent backflow from the downstream system, when the pump shuts off. Check valves are used to prevent contaminated media in branches from flowing back into the main trunk line.
Where is the best place to put a check valve on a sump pump?
Sump pump check valves should be installed close to the floor after the pump, as shown by arrow #1. This will reduce the amount of water that drains back to the pump after each cycle.

Should all sump pumps have a check valve?
Improper Installation or Not Installing one at all Not having a sump pump check valve installed causes the water in the discharge pipe to empty back into the sump pump pit. This makes the water level in the sump pit rise and a high water level can cause the pump to run more often, increasing your energy costs.
Can you run a sump pump without a check valve?
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.
Do you need a valve before a pump?
A pumping system typically requires three valves: an inlet (suction) shut-off valve, an outlet (discharge) shut-off valve, and a check valve between the pump discharge nozzle and the discharge shut-off valve to avoid reverse flow and protect the pump from backpressure.
What comes first check valve or gate valve?
Check valves must be installed in the position prior to the pump's outlet, outlet control valves for servicing check valves. The outlet of the general pump is first soft connection, then check valve, and finally block valve. Install the check valve before installing the gate or butterfly valve.
How high should a check valve be on a sump pump?
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.
Can check valve be installed vertically?

Check valve in between well and pressure tank?
Hello, I've lived in my home for about 4-5 years and have always wondered if the random cycling of my well pump could be do to me not having a check valve between the pump tank and the well/pump. The house was pre-existing, but I really question the ability of the pump to hold the pressure in, let alone to not have any small leaks in the piping all the way up from the well in the ground.
The Most Common Causes and Symptoms of Check Valve Failure
A failing check valve can be a disaster when you’re operating any liquid handling equipment. By understanding why valves fail and how to detect the early warning signs of valve failure, you’ll be able to prevent them from failing in the first place and avoid costly downtime and repair.
Is check valve at pressure tank necessary? | Terry Love Plumbing Advice ...

Deep well pump check valve | Terry Love Plumbing Advice & Remodel DIY ...
Well I've been shopping around for pumps. Every one tells me to put a check valve every 100 feet. It's a poly pipe. I plan on putting an extra check valve at the pump anyway.
What is a check valve?
Check valves, or one-way valves, are designed to stop backflow and, ultimately, to protect pumps and compressors. They are available in several styles and sizes, from 1/8 inch to as large as may be required. Check valves are found in many industries and with various applications ranging from municipal water to mining and natural gas.
How does a valve lifespan affect a pump?
The valve lifespan can be greatly increased by reducing the risk of parts breaking off and damaging equipment downstream. It protects the pumps that are upstream by not allowing backflow, which can cause the pump to spin in the reverse direction and cause severe damage. It leads to better pump and compressor protection.
What is a full port check valve?
This is probably the most common check valve in use today and is a full-port design, meaning the disc, when fully open, is out of the flow stream. This style of check valve is a good choice in applications that have a high percentage of solids and a lower on/off cycle count. Due to the travel distance of the disc, swing check valves close slowly. This causes the last push of reverse flow to slam the disc closed, resulting in a huge pressure spike, causing water hammer. Water hammer is a pressure surge when a fluid in motion is forced to stop or change direction suddenly, causing a pressure wave in the pipe. This pressure wave can cause major problems from noise and vibration to pipe collapse.
What is a full flow valve?
These full flow valves typically incorporate a center guided stem-disc assembly along with a compression spring. This means the disc stays in the flow stream. The media flows around it and does not require manual or automated assistance to operate. When the pump is running, the valve is open. When the pump shuts off, the valve closes slightly before the reversal of fluid flow, due to the compression spring force acting on the disc, which nearly eliminates water hammer.
What to consider when choosing a valve?
Other things to consider are working pressure, flow rate, the specific gravity of the media and temperature. An analysis of the system design is highly recommended. It is necessary to understand why valves fail and the root causes.
Why do valves fail?
It is necessary to understand why valves fail and the root causes. The most common failure is due to excessive wear of the internal parts of the valve. Springs, discs and stems wear prematurely by not being held steady during operation.
Is a water hammer valve better than a swing check valve?
It has been proven that this is not the best choice when faced with water hammer, though they will perform better than a swing check valve. Generally, this style of valve is considered an off-the-shelf commodity valve with little customization available.
Where should a check valve be installed on a well pump?
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. Click to see full answer.
What are the symptoms of a check valve failure?
Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Then, does a deep well pump have a check valve?
Do submersible pumps have a check valve?
Check valves permit water flow only in one direction and are required on all submersible pump installations. Some submersible pumps have built-in check valves, and are suitable for operation without an external check valve, provided the pump setting is not too deep. Where should a check valve be installed?
Why do pumps need two valves?
These help to regulate pressure within a pump and prevent against possible breakage. Any pump should have two valves attached; one at the inlet, or suction, and the other at the outlet, or discharge area. Valves must be installed at the correct distance in order to insure maintenance and safety.
How far away should a pump valve be from the outlet?
For example, if a pump has a 1 inch inlet and ½ inch outlet, then a valve should be placed a minimum of 10 inches from the suction side and 5 inches away on the discharge. When trying to control the flow of the pump, always regulate the flow using the valve on the outlet side.
What is March Pump?
March Pump encourages the use of valves that are designed to keep friction losses at a minimum. Popular choices are ball valves and gate valves. Ball valves are valves with a spherical disc which has a hole through the middle. This controls the amount of flow through the pump. These can attain perfect shutoff of flow.
What is a gate valve?
Gate valves are valves that open by lifting a “gate” or wedge out of the path of the liquid. These are primarily used to permit or prevent flow, but should not be used to regulate flow. Conversely, valves such as solenoid valves (electromechanical valves controlled by an electric current through a solenoid, or helix coil), ...
What happens when a liquid is forced to stop?
This is a pressure surge that occurs when a liquid is forced to stop or change direction suddenly, which can result in breaking the rear housing. If you are using a solenoid valve, increase the time it takes to close the valve to reduce the chance of water hammer from occurring.
Is it bad to start a magnetic drive pump after dry running?
The valve on the suction side should only be closed when the pump is turned off. Upon startup, the valve on the outlet should not be fully open, it should be partially closed to generate some extra backpressure.
What is the purpose of a pool check valve?
PURPOSE OF A CHECK VALVE - In general a pool check valve in installed in your circulation system to keep water from flowing backwards in the system when the pump is turned off. Common uses of a check valve are discussed in the following steps.

This is a type of check valve because it only allows flow in one direction. Similarly, where does the check valve go on a pool pump?
Why do I need an external check valve on my pump?
External check valves are usually installed on impeller type pumps to prevent loss of water or unnecessary head pressure at the impeller. Strainers should be installed on the suction side of the pump to prevent debris from entering the pump. I origin put mine before the pump. The pump did not work properly. Click to see full answer.
Where is the check valve located on a filter pump?
As such, a common location for a check valve is on the incoming suction pipe, in front of the filter pump.
How to tell if a check valve is leaking?
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.
