    Hi all, this is my first posting here. Glad I found this forum!

    Our house is on a well with the pump located outside at the well. All the filters and softener is in the garage. I have installed a chemical injection pump at the filters for chlorine and PH. The well is now pumping what is called "red water iron" and keeps fouling out the water flow switch for the injection pump. My last resort is to move the well pump to the garage and eliminate the flow switch.

    Question: The PVC pipe feeding the well pump is 1 1/4" and the line to the house (100+ feet) is 1". The supply line is then reduced to 3/4" to all the filters and softener then 1/2" to the faucets. Can I install the pump where the 1" line reduces to 3/4" or do I have to run the 1 1/4" all the way to the house?

    Thanks for any and all advice!

    Do away with the flow switch. You should be able to hook up the injector to the same pressure switch that starts the well. That way the pressure switch starts both the well pump and the injector pump. I don't think you want to move that pump to a smaller line.

    That's what I am going to do, but to leave the pump where it is would mean having a huge box in the front yard. That would house the pump, pressure tank, chemical pump and a 16 gallon chemical tank.

    I know that as distance increases from the well pump that the water line has to be reduced to maitain good pressure. What about the supply line from the well to the pump? Does it have to remain the same size from the well to the pump? It would be 1 1/4" out of the 60' well to the surface, reduced to 1" to run roughly 120' to the pump and 3/4" from the pump.

    Thanks again,
    Steve

    The line DOES NOT have to be reduced to get more pressure. In fact it is just the opposite. Larger lines will help you keep from losing pressure to friction loss.

    You can push water a long way with a pump but, the further you try to suck water with the pump the harder it is.

    Going that far to the suction of the pump I would use at least 1 1/4" pipe and 2" would be better. Then leaving the pump that 3/4" is not doing you any good. Stay with as large a pipe as you can before and after the pump.

    Gary Slusser That's all folks!

    Describe the exact type and order of this water treatment equipment from the well to the house.

    Chlorine oxidizes iron making the water rusty orangish reddish brown.

    I agree with valveman, the bigger pipe the better you are. Even if you don't notice a pressure change the pump is still working harder meaning more maintenance risk.
