Pushfit gas?

    I fairly sure pushfit joints arn't allowed on gas, therefore, I rest my case in that they are not as reliable and trusted as soldered copper.

    What a Luddite you are!

    Don't you know anything about plumbing?

    Millions of miles of plastic plumbing is used today. All underfloor heating is in plastic as copper is unsuitable!

    Speedfit is not only used for plumbing - it is used in aircraft, submarines and automobiles for fuel lines etc.!

    Of course copper is good too and soldered joints are excellent but NOTHING is foolproof and ALL joints have the potential to fail.

    But prattling on about "inferior plastic" only serves to make you look a bit dim.

    Remember in some countries you can't even use copper for gas ! it has to be iron:D

    I pass a lot of gas every day, probably due to all that bending down and I can assure you there isn't an inch of copper in my system apart from a bit of loose change in the jeans.

    Using the same flawed logic.

    Soldered fitting aren,t allowed on oil pipes - so they must be unreliable.

    And drain pipes are not made of copper so that must be rubbish too!

    I bet BB feels a bit of a * now!

    you cant use pushfit on gas because it would melt in the event of a fire, anything above ground is usually in screwed iron pipe to the meter etc

    I'm old enough to remember the old lead gas pipes and joining onto them with copper.
    It was much thinner than lead water piping and much easier to joint because you only needed to wipe a flange joint.
    However,even back in those days there used to be some controversy between plumbers as to wether or not you could flange copper straight in or to use a brass fitting between the lead and copper.
    That fitting was called a 4u.
    Ah, the olden days!
    You know I'm beginning to sound like my old grandfather :)
    Tappy,

    And as far as I know Tapnuts,youre still allowed to wipe a flange lead joint to a gas copper pipe,not that half the numbnuts on here could do one? ;)

    Soldered fitting aren,t allowed on oil pipes

    Why's that then ?

    Because the kerosene may cause the the solder to decompose - Alledgedly

    It would also fail in a fire.

    Tappy,


    It was a cup joint and it was never wiped. The solder was touched on using a low heat blowtorch. It was a 4U union joint - 4U was the Gas Boards number for the union fitting. It was for disconnection only. Copper could easily be soldered directly into the lead. The Gas Board wanted a disconnection point.
