service valve in heating system
I need to remove a radiator, dry line the wall then fit new diferent
shaped radiator a few days later. To save draining down twice id like to fit a pair of service valves in the pipes leading to the new rad whilst I do the dry lining and other work. My question is. Is it acceptable to use normal service valved and leave them in the system? Mike |

If your radiators have valves on both ends already just close those and leave them attached to the pipe ends. Tim -- Please don't feed the trolls |

Tim What I was thinking - even if the valves need moving when fitting th enew radiator - it is only one drain down. |

What I was thinking - even if the valves need moving when fitting the new radiator - it is only one drain down. May not even have to do that with an open vented system. When it comes to the replumbing for the new rad block the feed and expansion pipes at the header tank and ensure there is only ever *ONE* opening into the system. Air can't get in. water can't get out, at least for vertical pipes open at the top. There might be some spillage so be prepared... Horizontal may well "glug" and drain out and then any vertical pipes leading up from that horizontal, especially with the vibration and banging about cutting/making joints etc. You can certainly change bottom fed radiator valves this way. The absolute key is ensuring that there is only *ONE* opening into the system at any time. -- Cheers Dave. |
