    What are changeover valves?

    If you use bottled gas to heat your property be it, your main home, mobile home, log cabin even a boat the chances are you have a changeover valve installed.

    Hose pipes known as pigtails connect to these valves. You may have a two hose or a four hose setup.

    The gas needed for each appliance to work safely is calculated and will determine how many hoses and bottles you will need.

    Changeover valves can be either automatic or manual.

    Automatic valves will change from the empty bottle over to the full bottle.
    If you have a four-bottle setup, you will be using two bottles at the same time.

    When these two bottles become empty, the valve will switch over to the other two bottles without disrupting the gas supply.

    Manual valves are just that when the bottle or bottles becomes empty, you have to switch over yourself manually.

    When using the four bottle setup, the changeover valves should incorporate an opso, it a safety device that locks out if the gas supply gets over-pressurised.

    When purchasing changeover valves, it’s a good idea to contact a Gas Safe Registered engineer (LPG Registered) to advise on what valve you need.

    These valves very rarely break but the occasional one will.

    A little tip to follow is when changing over the gas bottle is to open the supply gently.

    Sometimes if you open the bottle supply quickly, it lets the gas in too quick and breaks the valve.
