    I am ready to permanently run the intake plumbing to an irrigation pump on our dock. How should I run this and how should I hold it down on bottom.

    I am thinking that I will come off the pump intake, down into the lake and down to the bottom then run the piping through several cinder blocks spaced one per 10ft or so until I get it out to deeper and weed free water, then put the foot valve.

    Also, is some sort of filter recommended over the foot valve?

    If you plan a permanent fixed suction line to a pump, you might do with a check valve at the pump intake, rather than a foot valve. That approach also gives you some freedom to choose an intake strainer/screen that fits your system and sprinkler heads, in the event that they want cleaner water.

    Some folk use a sandpoint and a checkvalve instead of a footvalve.

    I use 2" pvc about 3 foot long with 1/8 inch holes drilled every 1/2 inch. Then I have a fiber filter over that, that I can rinse easy. It will stay on the bottom when filled with water.

    That keeps fish from getting sucked up and sticking to the inlet.

    However you do it, you will have to clean some type of filter on occasion.


    Good Luck.

    You need to make sure your area will allow a sandpoint in the lake. It will most likely be in the mud, in your area.

    Some locations do not allow taking water from a lake for irrigation. Temporary is a bit different than permanent.


    Good Luck.

    We have to pay a yearly fee to draw the water, but it is allowed. Most homeowners on the lake pump water from the lake for their irrigation system.

    That is good.

    You have more fresh water than we do.

    How big is your pump inlet ?


    Good Luck.

    I guess people around you would know how to do it properly.

    It will have to be done in a way to protect fish from sticking to the inlet.

    And keep boat props out of it.


    Have Fun.

    If you have a sandy bottom, you can shallow bury it horizontally. They also come in metal in many sizes.

    So it is buried in the sand, mud or whatever is on bottom and still draws water without plugging up?
