    Default main water pipe

    G'day folks, hope you all had a good Xmas.

    We are about to concrete our driveway. The main water pipe for the house runs up the driveway and will end up at least being 70% covered by the slab.
    It is a 25mm black poly pipe laid about 1992 with a tap running off to one side in 2 places connected by compression joints. These joints have recently been replaced in the last couple of years as they failed - again.

    Should I replace this pipe run with something more durable or would the slab protect it from further harm? Would be nice to prevent a future potential problem happening where I would have to cut up the concrete.

    It is buried in heavy clay soil.

    I would move it out from under the slab. Or you could wait for it to fail again then simply run a new line around the slab picking up the other two points along the way rather then chop up your new concrete to fix it.

    OK, thanks there mate.

    Is there a better choice of materials to use?

    Unfortunately moving away from the slab is not really an option, so looking to see if upgrading the line in any way would help

    If it were my place I'd be using copper. I can't for the life of me figure out why, in all their infinite wisdom, the committee that write the standards still let people use plastic pipe in the ground or chased into brick walls.
    Any of the approved PEX piping systems will do. If you go with the PEX pipe, buy some 40mm uPVC pipe to use as a conduit, tape up all the joins and do all you can to protect it.

    G'day,

    I had a similar prob with my phone line, conc goes in, 3 months later no dial tone. I managed to get a Telstra bloke with a few smarts and he sorted it by boring under my new driveway. My suggestion is to run a 65mm or 100mm conduit, under the proposed driveway to an easy access point/pit by the house for any un planned future issues...

    Good Luck...

    Thanks for the replies, guys.

    I'll go with the copper pipe in a conduit idea.
