    Looking to tap into a 15mm cold water feed with 25mm MDPE pipe to run to out door koi pond. Read on the forums a wider pipe ie 25mm would allow better pressure hence the size difference.

    Its probably really obvious but what connection would i use? i`ve seen copper to MDPE tee connectors, would flo fit push connectors do the job or am i looking at ALOT of joints/reducers to get the connection.

    Can't really see any benefit in running 25mm, 20mm poly should do and you can easily get 15 - 20 mm couplings.

    It would make very little difference to the pressure using 25mm or 20mm pipe, you would have a slightly better flow rate using 25mm but don't think the fish would be that bothered.

    Cheers for the replies, fastest customer service i`ve ever known.

    I`ll return the 25mm and get 20mm and some connectors.

    Keep it simple stupid! :rolleyes:
