    Morning,
    I'm going to replace my old 15mm water pipe (lead?) with 25mm mdpe. Ill be doing the trench and laying the pipe etc for Thames Water to connect.
    Query is should I get the communication pipe replaced which is almost certainly 15mm?
    People generally seem not to and get much better flow just from the new 25mm pipe run.
    Thames Water want £500+ to replace the communication pipe....
    If its relevant I do have a water meter.
    Thanks.

    What do you mean by the communication pipe?

    Its the pipe that runs from the water meter / stop cock to the water main in the street (see diagram below).

    Ah, I never knew that (y)

    If you meter is new(ish) it will have 25mm connections so the communication pipe may already have been replaced/renewed.

    Yes my hope is that that it was replaced when they did the meter but they might have done a cheapo job and just tied into the existing lead pipe. Only know when I dig I guess...
