    Retro bottom drain x2?

    Out of curiosity does anyone have any experience or opinions on running 2x retro bottom drains from the same pump?

    I saw a YouTube video recently where they installed 2 of the retro drains onto one pump (20000lph iirc) and claimed it worked well,as far as I can see the pipework wasnít equal lengths up to the pump

    Thereís a couple of things I canít get my head round
    A) How would it pull equally-surely the shortest pipe run would get all the pull?
    B) Is there enough draw from a single pump to even make them effective? Iíve ran a single retro drain on a 20000 and even at full whack I thought the draw wasnít great

    Hi, I think you would be better of, with one bottom drain. Would give you a much better pull on the bottom.
