Why does my well pump have two pipes?
“Two line” refers to the fact that two water pipes connect the pump to the well. Well Jet & Foot Valve Clearance from Well Bottom: (not shown) means that the well piping, bottom venturi, and foot valve are inserted into the well some distance from the very bottom of the well (inches to a few feet).
What is the difference between a foot valve and a check valve?
Check valves and foot valves are designed to stop water from going backwards when the pump shuts off. Check valves are normally on the discharge side of pumps, and foot valves are on the intake of pumps. The more check valves in a system, the more friction loss.
Why is the water pump not working?
Your well pump may have stopped working due to lack of power. Sometimes resetting a breaker or replacing a fuse affected by a power surge or brownout can fix this. If the well pump circuit breaker has tripped, the well pump itself may be failing. Then switch the circuit breaker off and on.
When to use a foot valve in a jet pump?
A foot-valve is only used in a jet-pump situation (where the pump resides above ground and shoots some water down the well to help lift more water back up).
What does it mean to have two line jet pump?
“Two line” refers to the fact that two water pipes connect the pump to the well. Since the lift capacity of a two-line jet pump is not limited to the shallow-well depth of 27′ chances are that where you find a two line jet pump installed it is drawing from a deep water well.
Where is the check valve on a submersible pump?
In a submersible pump situation, it is technically called a check-valve because it sits immediately above the pump rather than below, but it is commonly referred to as a foot-valve and works the same way. If your pump cycles on and off when water is running see resource article on “short cycling.” This is not a foot valve issue.
How do you remove a foot valve from a submersible well?
There should be a gasketed flange attaching the well pipe to the sidewall. Pulling up on the flange with the winch will disconnect the pipe from the feed pipe to the house. Pull the pipe up out of the well a couple of feet using your winch and clamp your 2x4s onto the pipe to prevent it from falling back into the well.

How does a single line jet pump work?
Most “shallow water wells” are less than 30 feet deep (so the foot valve is at 24-feet depth or less) and use an above-ground single-line jet pump to “suck” or draw water up from the well. These pumps cannot pull water from much deeper. Water from deeper wells is delivered by a 2-line jet pump (also above ground) or a submersible in-well pump.
