    Thanks Jon.
    What's your thoughts on HDPE or MDPE for the pond collectors and SDR 11 or 17?
    Does it make much difference if the wpioework won't get to freezing?
    MCS calcs on here:

    Hi Woodgnome usually HDPE is the pipe of choice and we tend to use SDR 11 to avoid nuisance kinks in the weaker SDR 17, but you might need your installer to confirm that the flow is turbulent in the active elements with whichever you choose.
