Why do you need a strainer for a foot valve?

Why do you need a strainer for a foot valve Strainers are used to protect the valves it will prevent the accumulation of debris, the debris could jam the foot valve, and it could damage the pump. So strainers are an important part of a foot valve.

What is the function of foot valve and strainer?

The foot valve is a lift check valve which is usually installed together with suction strainers in the suction line. It prevents the suction line from running empty after the pump is stopped (also see Valve).

How does a foot check valve work?

A foot valve is found at the end of a pipe line in a suction lift application. They function as a check valve, but they also have a strainer affixed to their open end. The check valve is spring assisted. When the pump turns on, the pressure inside the pump column changes and the valve responds by opening.

Can I use a check valve as a foot valve?

Can I use a check valve instead of a foot valve? The only differences are that the foot valve has a screen on it and a check valve does not, and a check valve has threads on both ends so you can put it in line. A foot valve only has threads on one end because it’s meant to be at the end of a pipe.

Do I need a check valve and a foot valve?

We recommend using only one check valve or foot valve in a pump system. A foot valve should be at the inlet to the suction line of turbine, centrifugal, and jet pumps. If an additional check valve is required, it should be placed after the pressure tank to allow the pump and discharge pipe to remain pressurized.

Can we use check valve instead of foot valve?

Do all wells have a foot valve?

Nearly all well pumping systems, one line jet pump, two line jet pump, or submersible well pump, require a foot valve installed at the bottom of the well piping. Foot valves are also used on deep well installations to help protect against loss of prime in the well piping system.

Why do you need a grid strainer for a foot valve?

The strainer also keeps debris from becoming lodged in the foot valve. This would result in the valve being stuck in the open position, and all the fluid draining from the pump column. That nullifies the point of the foot valve! Some foot valves offer tight mesh, others offer a wider grid strainer.

Why do we need a foot valve and how does it work?

This strainer filters the incoming water, thereby preventing debris in the well water from entering into the pipe and clogging the valve, jamming it in the open position. Pumping water from a lower level to a higher level requires a lot of energy.

What do you need to know about a strainer valve?

What is a strainer valve? Strainer valve can be defined as a pipe fitting through which liquid is passed for purification, filtering or separation from solid matter; anything used to strain a liquid; any device functioning as a sieve or filter used to prevent solid bodies from mixing in a liquid stream or flow line.

What happens if a foot valve is stuck?

Even a small amount of debris can be detrimental to the pump’s internals. The strainer also keeps debris from becoming lodged in the foot valve. This would result in the valve being stuck in the open position, and all the fluid draining from the pump column. That nullifies the point of the foot valve!

What does a foot valve on a water pump do?

As you may guess, a foot valve is basically a check valve combined with an inlet strainer (visible in our page top photograph). The strainer prevents picking up large debris that could clog or jam the foot valve in its open position (or that might damage the water pump itself).

What kind of valve is used for a strainer?

Consequently, strainers designed for use in steam systems usually have a drain plug, which can be fitted with a steam trap to remove the condensate. The most common material used for Y type strainers and Basket strainers bodies are cast iron, bronze, carbon steel, stainless steel, and plastic.
