    Hi,
    I need to replace a sprinkler system in an old house and the pipes coming out of the house to the new sprinklers values are metal. Is there anything special I need to do to get the metal and pvc fittings to fit together properly or should things to screw or slip together fine?

    Thanks,
    Dave

    Metal and plastic expand and contract at different rates. usuallly a rubber go between peice is needed to prevent cracking.....

    PVC pipe needs to have male threads, metal pipe needs to have female threads. Not the other way around.
