How to drain a central heating system

Love this guy. Any plumbing stuff I do, I always seek this guy out.

Thank you - you have made it sound so simple and logical to drain down my system whilst I change valves for a new radiator. I am even thinking about moving the pipes into a wall channel to avoid tiling around the pipes that currently project out of the floorboards.

Thanks me old mate, once again your videos are saving me money, I’m most appreciated for this, I need to clean the heating system, Worcester boiler has been with us for 7yrs, but I’ve never done the clean out of the rads. Needs to be done with fresh inhibitor. Trying to stop that crackle sound when someone upstairs having a shower turns off the hot water. Many thanks.

Great video Al. I learn such a lot from your videos - really clearly explained. Thanks

Nice one Al, I did mine (F&E) yesterday but watched your video anyway. Keep up the good work 👍

What a brilliant informative chap. Always watch his videos everytime I have any sort of plumbing issues.

You save me loads of money and keep me out the wife’s road. She and I thank you loads. Stay well and stay safe and keep making great videos. Ash from 🏴󠁧󠁢󠁳󠁣󠁴󠁿

Love this Guy hes made my plumbing jobs so easy with all the good advice. My next job is to change a radiator and valves. Thankyou!

Best, simplest explanation I’ve seen so far!

Good video Al.. I'm flushing & cleaning my f&e system in the week as it's venting into the tank. I can use a bungy cord to hold up the ball valve and empty and clean the tank first, so the rust laying in the bottom of the tank doesn't go down through the system, (I think I have enough sludge already in the system causing the problem) I can also turn off the mains stop valve in the loft which feeds both the big main water and f&e tanks, so that's handy.. I'll just have to watch that when I refill with the cleaner that the system doesn't overflow so losing the cleaning strength.. 👍

Thanks governor. Great explanation great video as usual

You couldn't explain any better. Great video. Thank you

Well done your instructions are so clear. Thank you.

Many thanks I’m learning fast your the best on u tube.

Thanks for the video, was very useful. At which point in the re-pressurising my combi boiler should I add inhibitor?

Brilliant explanation - thnx so much for making this process simple and understandable

Hey Al, going to execute this next week. Wish me luck👍

Thanks mate you explain stuff very well

Thank you so much,your video helped me drain the system and replace a radiator after a teenage darts incident.Mny Thanks Sy

Another great video, thank you. Can I just switch of the water in a system by closing the valve on a filling loop?
