    IMPORTANT:
    Carbon Monoxide can be produced when ANY fuel is burnt, including oil, gas, wood and coal.

    Thinking lever valves are more reliable and quicker to turn off.

    The question was about isolating the sections of a heating system if you read it.

    Try not to be condescending and pay more mind to being helpful.

    I have been an Industrial Commercial and Domestic Heating Engineer for 28 years, So I do know not to valve off a boiler as you suggested !

    What has Gas awareness week got to do with Heating system sections ?

    They're full bore valves designed for the open vented system circuits we're discussing.

    They have less restriction / frictional resistances to ball valves.

    They're serviceable !

    Lever valves for water & gas can be full bore, take your point about being serviceable though.

    I've come across lever (full-bore) valves and gate valves from the early 90's in the same block of residential flats, guess which ones didn't work......

    I agree gate valves are serviceable but there are two issues. One, if they worked as well as a branded full bore lever they wouldn't need servicing. Two, if you service a gate valve for a customer and it then fails, you end up getting it in the neck from the customer....

    "it was fine till you touched it" etc etc....

    Don`t know if the usual plastic push fit valves are full bore or not but do know the beggers start leaking whenever I go near them. lol

    I agree. The problem a lot of the time is that decent quality 'lever type' ball valves are on the shelf. However, most shelf stocked small gates, 15mm or 22mm are Crud !
    If you buy gates like Crane, the quality is very good. It's all a matter of opinion though.
