How to do the quick change (THE SNATCH). Freezer kit not required. No going up in the loft and plugging up the F and E tank with plugs. Save hours draining the whole system and refilling afterwards.

  • This fella is easily one of the best channels on YouTube. I bet all the jobbing plumbers and sparks come here when they want to know the real tricks of the trade! I wish my dad had made videos like this when he was around. 🙏🏽 God bless you Dereton33

  • Thanks once again for a live changeover- always nice to know what you are letting yourself in for
  • thanks for the video Derek really easy to do I had room to change the basic valve over to a tvr with a bucket so any spillage in the bucket 👍

    I like to open the TRV and release some of the pressure out of the central heating system. Great video as always 👍

    great ,just subscibed,i no expert but have done plumbing /heating work as a helper,its worth mentioning that the old valve nut may not easily go onto the new valve,have your small hacksaw and flat screwdriver to hand...great videos thank you.

    Great snatch Al, well done, I can see you have done that before 👍👍 Much appreciated, thank you.
  • GREAT a lot of plumbers say put bungs in tank iam disabled can not get up in attic no need for that the way you show us Thanks
  • This was very useful. I was only 2:18 into the video before I'd have paid to watch this. Thank you.

    You’re a legend. There’s things available now that better help snatching. Rubble bags, absorbent mats(nappy mats) etc. good stuff fortune favours the brave. I like rubble bags easy to manipulate around pipes etc

    always wanted to do it this way. i just dont have the nerve unfortunately. Great video as always
  • @Gelp
    A really helpful video thank you! Sadly the two troublesome valves I have are stuck open, so I can't do this. But I wouldn't have known if you hadn't mentioned this in your video. Time to get a plumber out! 🙁
  • You can also drain the radiator by closing both valves and using the drain valve integrated into the lock shield valve. But you have to fully drain the radiator in that case.
