Best Sump Pump Check Valve Reviews 2018

Have you ever wondered how does the water is discharged out of the sump pump in one direction and not backwards? If you do wonder, the reason behind is because of a check valve located on the discharge pipe. The best sump pump check valve helps to prevent the backflow of water into the tank when the motor is turned off.

How does it work?

The check valve works based on the flow of water. The internal disk present in the check valve allows the water to move forward which opens the valve and automatically closes when the forward flow declines or is reversed.

How to Choose The Best Check Valve For Sump Pump:

There are various sump pump check valves available on the market. Each of them differs substantially in terms of price, quality, durability, performance and etc. Before procuring a check valve for your sump pump have a look at the following points.

Budget: Estimate the budget that you wish to spend on a sump pump check valve. Check valves are available in various price ranges.

Type of sump pump: Know about the type of pump system that you have installed. Sometimes the check valve might fail to work due to mismatch with the pump.

Power level: Also know the power level of the sump pump. The check valve must be capable of functioning with the horsepower of the sump pump.

The frequency of use: Know the frequency of flooding or the frequency of usage of a sump pump. If the frequency is more then buy a branded check valve which can last for along time.

Speed: It emphasises on the speed at which water has to be moved. Select a check valve which can act at a similar speed.

Noise reduction: Emphasis on silent check valves. Check valves can create a loud banging noise when it is closed. Therefore choose a silent one.

Durability: Wish for a metal check valve which ultimately increases the lifespan of the valve. Plastic check valves have less durability than metal valves.

Diameter: Check the diameter of the pipe fitted in the sump pump. It is advisable to take a piece of pipe to get a right fit.

Benefits of Good sump pump check valves:

By choosing the best sump pump check valve, you can enjoy the following benefits

  • Attaching a check valve ensures one-way flow of water and prevents back water flow. This prevents the water to get into the tank again when the pump stops.
  • By fixing a check valve, the life of a sump pump can be improved. When a check valve is not fixed, each time when your sump pump turns off the water rushes back to the tank and causes wear and tear to the pump which in turn reduces the lifespan.
  • Most of the check valve can be used as both vertically as well as horizontally.
  • Fitting a right check valve can eliminate water hammer (causes when the flow of water gets reversed). The valve that does not rely on reverse gravity flow but uses the spring to close will prevent water hammer.
  • Check valves reduce vibration in the pipe. It uses the velocity of the fluid to increase pressure against the valve disk which moves the disk smoothly and gently which in turn reduces vibrations.
  • They act as pressure regulators which in turn saves energy. It helps to reduce the hammering noises by replacing an old valve with a “soft close” or “silent” check valve.
  • The check valve can be replaced without cutting the pipe when it needs to be serviced. Therefore it does not take more time and energy to change to change the check valve.

Conclusion:

As we conclude that check valve is an unavoidable part of sump pump which has many added benefits. There is a huge number of check valve models available in the market. Each valve has its own merits and demerits. Need changes from person to person based on size, location, budget, brand, speed and pressure required. With the help of the list of check valves provided above, see whether your needs match with the features of the check valve. Therefore evaluate your needs wisely and choose the right check valve for your sump pump and make the best use of it.
