    Hi all, suppose to be buying this on saturday.. . tight for time now . . .

    The mains is running along the main road, my house is 450meters back from it, so i have to buy 450 meters of pipe. the site is about 35-40 meters above road level.

    I was originally thinking 3/4 inch pipe back to main house. .

    so, 450meters back from the mains and a 40 meter rise, what would you recommend??. I had a guy on site today and mentioned go with inch & 1/2 or even 2 inch, saying also that i would get good pressure with this (and that i would loose water pressure with distance and rise.

    I was originally getting 3/4inch high gauge wavin, but then i was made aware of blue alcaline water pipe which they use in the uk and NI. and given the distance, the Blue alcaline pipe(or what i think it is now from reading on net is Polybutylene) (ignoring the FX rates and NI cheaper) still works out way way cheaper,

    3/4 inch wavin for 430 meters i got it at €470
    3/4 inch Blue Alcaline for 430 meters £140

    is there any preference which i use? blue alca or wavin,


    so, im stuck with 2 decisions which i thought i had made. . and now its

    What thickness??

    and wavin or blue alcaline??

    immediate ideas/thoughts/responses would be brill. . .

    thanks for your time in reading this.. .

    just read this on the councils website

    "Unplasticated Polyvinyl chloride (uPVC) pipes shall comply
    with the Provisional Local Government Approval Scheme (PLGAS/7) or with any
    subsequent revision thereof (or equivalent). Polythene pipes Type 32 (Heavy Gauge
    Only) shall conform to I.S. 134/1977 or equivalent. Polythene pipes Type 50 (High
    Density) shall comply with I.S. 135/1975 or equivalent"

    "I also hereby agree to the conditions hereunder, if the extension is greater than the standard (½”) 12mm diameter supply.
    1. The watermain and service pipe shall be laid in piping of such materials and of such dimensions as may be determined by the County Engineer.
    2. The connection with the public watermain shall be made under the supervision of such person as may be appointed for the purpose by the County Council.
    3. The total cost of the watermain and service pipe, the laying thereof, the Water Service Control Unit together with the connection to the watermain shall be borne by the applicant for water supply.
    4. The extended watermain when laid and approved of by the Council shall be taken over and maintained by the Council with a right to grant further service connections on the conditions laid down herein.
    “Watermain” in this context means any pipe having a bore larger than ½”.

    As per your post above your pipe type and size may well be determined by the local council. They can be accommodating at times :)

    As Muffler said, the reigonal engineer will specify the pipe for you, they are precise and won't allow you connect anything other then they specify, usually.

    this i know, but i also know that if the max i can connect is half inch or 3/4 inch it does not matter what i have on the site. .

    i could run a 4 meter 1/2inch to suit council and then step it up. . I am responsible for it so ill be looking after my own needs. sure its easier for the council to say 1/2 inch, its less hassle as its std but it wont suit me.

    does many people use poly pipe? the blue pipe?

    This will just lower the pressure.
