    Default Newbie here! problem getting water from my lake

    Hi there,

    I live in south florida with a lake behind my house. I have a 2 hp goulds pump and it sits above the water line and it is mounted 100 feet from the lake. I ran 2' inch pvc to the back with a horizontal check valve at 80 feet. My strainer sits about 15 feet into the lake submerged. I can not get the water to come up, I dont know if the check valve has to be put in the end where the strainer is. I have been searching on here for my issues but havent found anything that explains my situation.
    Thanks in advance

    You have to fill that line and the pump full of water before it will pump. If you have any high spots in the suction line it is almost impossible to get the air out. The foot valve is all you need, it is just hard to draw water from that far away.

    Thank you,

    So instead of the check valve at the end, all I need is the foot valve or both?

    Yes, I have high points all the way to the back, it is about three feet above the
    lake water.

    You only need a foot valve at the end of the suction line.

    If you want restful sleep, put in a submersible. Not only will it pump more for less money but it will never need priming.

    Well,

    I bought the foot valve and installed it. I primed the pump and hit the switch, all I brought was the water left in the line from the city water. I did it a few times and nothing happened, now I am totally lost! Why is it that my 2 hp gator pump does not open the valve to let the lake water in? I am priming it on the inlet side, what else could I try before I call an expert? thank you in advance

    Are you putting the water into the top port on the pump?

    How much water are you putting into the pump?

    Are you allowing all the air to burp out before putting the plug in and turning the pump on? If there is any air in the suction line the pump will not pick up prime.

    Whenever I work on a jet pump I like to have a ball valve on the discharge side so I can bleed off the air slowly.

    Thank you craigpump,

    I have the city water hooked on the inlet end of the pump. in front of the pump threw a water hose valve. In the bottom of the front of the pump there is a plug, I do not see any other plugs anywhere to bleed the system. I never bleed the system, so how am I suppose to bleed the system to get the air out? that is what the pump sounds like it has air in it. I will take a picture of my set up in the morning....thank you

    It sounds like you are keeping the hose hooked to the pump when you start the pump. What you want to do is slowly fill the pump and suction line through the top port on your pump. Allow the air to burp out, refill the pump, burp the air, refill the pump.............When the pump and suction line are both completely full of water, disconnect the garden hose and then turn the pump on. If you don't have a valve on the discharge side of the pump, leave the plug loose so what little remaining air will bleed out.

    Welcome to the world of centrifugal/jet pumps.

    Here is my well pump, the only bleeder screw I see is that one on the bottom. If that is the bleeder screw, what do I do? remove it completely or loosen it. Again thank you for all the help

    Bleed the air out on the discharge side where the green hose connects.

    LLigetfa,

    I bleed it with the city water with the pump running or off. I`m sorry for all these questions, I just want to get it right.

    Thank you

    Both. Close off the discharge ballvalve. Pressurize the system with city water. Close off the city water. Open the bleed a small amount and turn on the pump. You want it to build pressure but at the same time bleed off the air. If you lose all the pressure, open and close the city water to get the pump wet. Lather, rinse, repeat.

    I will try this LLigetfa,

    Thank you again,

    Note: the foot valve is installed horizontal instead of vertical at the lake end. I just thought I should mention this.
