I will explain in detailed step by step instructions what's needed so you can carry out the work with little fuss or mess.
I will pass on all my "Tips & Tricks" I have learnt over the years. Which other videos seem to miss out.
The aim of my videos are to help you, whether you are a complete beginner or if you have experience in this work. With easy to follow instructions.
There are also other useful links to other heating and plumbing problems.
Being a Gas Engineer for over 20 years has given me a great deal of experience which I wish to pass on to you. Being a keen DIY person my self. I will show you in real peoples homes how to do jobs, also faults and problems I regularly find.
Even if you have know intention of fixing the problem your self, with my videos you should be able to identify problems and be able to call an engineer, who can then get straight to the problem.
I hope my video helps you.

Mark , so, so good. Brilliant tips
Thanks for the tips.
Hi Mark. Really informative. Thank You. Evidently very experienced and methodical.
You could use the rubberised handle part of the hammer?
Brilliant video
Great video
good one Mark, thank you
Great idea thank you.
Thank you
Mark what is the end connection you have at the end of your discharge pipe to keep the hose at the bottom of the bucket. Peter
Well Explained boss.
Useful video but I have one additional tip for larger radiators.
I took mine outside, used a hose adapter as suggested ( I keep old plumbing stuff so I managed to cobble together something)
I did as you suggested, including the hammer. However I really want to pick it up and shake it but it was too heavy(type 22 -110cm x60cm) I placed mine on a large unopened bag of garden compost and rocked the rad back and forward whilst holding it upright and with the hose running. This generated a huge amount of sludge, which choked the outlet at time but I kept rocking it back and forward till it cleared and run clean. I turned it upside down and repeated this perhaps 2/3 times over 20 mins. I used the bag initially to prevent damage to rad, as I was draining it direct to my outside drain, but when I started rocking it along the length, loaded of sludge came out
This is what I did with my rads recently- put them on a round 🪵 - half filled them before opening the outlet and rocked them back and forth - great way to get the gunk out
New subscriber. Do you flush the entire boiler system or just the rads?
Hi Mark, I’m just finishing off a full refit of my en-suitHi Mark, I’m just finishing of a full refit of my en-Suit … i.e new basin new toilet new shower basin and doors..and of course a new single radiator….I will also be replacing two more rads upstairs in the bedrooms…. So my question is, how do I flush the entire system after fitting the new rads…I cannot seem to find anything on RUclips..? Many thanks in advance.
William.
nice one.
I live in Farnborough. Fancy coming and doing mine and make another video!?!! 😊😆
Hi Mark great video, I have ecotec plus, 5 radiators to clean etc, need to drain the system but need hot water tap. Can isolate the heating ?
Just close both the isolation valves under the boiler first before draining
@@MarkBallardLTD thats what I thought many thanks,
I have this problem with one radiator and have found this video the best on u tube thank you from the Dordogne France.
Hi Mark, have you a video on Balancing your radiators? Thanks. I live in a bungalow (one level)
Is there such a thing as a two level bungalow? Fuck me.
@Mark: Do you have a parts list to the “accessories” and kit you have constructed there to flush out the radiators please..🙏🏼
Did you sort one in the end?
@@misfit1978 I did construct 2x tbh.. One for either ends.. ;-) [Havent used it yet, as the weather is horrible at the moment to work outside,and clean the rads.)
@@mariusenslin Yeah it's rubbish isn't it! I'm going to attempt it this week weather permitting! Could you give me an idea of what / where to get the parts from please?!
@@misfit1978 All The Best of Luck..and do let me know how you get on.
The parts list is as follows, and did I get it from and between Screwfix and tool station,and whichever one had the parts in stock and were the cheapest.
-2x "Made4Trade Lever Ball Valve 15mm" Red or Blue" - Toolstation (£4.80/piece)
-2x 15mm Copper pipe 80mm in length - Cut off/leftover pipe from a job I did.
-2x 170mm in Lenght Garden Hose - Grabbed it off the next-door neighbours hose that they were replacing
-2x Hozelock Hose End Connector" - Screwfix (£4.99/Piece)
-2x "Hozelock Double Male Connector Pro [Metal one] [Amazon - £7.79]
-2x "10-16mm Jubille Clips" - Have some in my toolbox
-1x "Ptfe Tape" [Screwfix - £0.25)
When you have dismounted the radiator from the system did you just shut TRV and lockvalve to stop water coming from the system? Or did you drainde the water from the entire system before removing radiator?
I just shut off TRV and lock valve. They don’t leak and does not effect other rads. You will need to top up pressure at the boiler after you refill rad
Great video- I have a 40 year old micro bore 8mm system. It works Ok. I want to put trv’s throughout. Should I replace the Radiators or just clean them out?
40 years old is along time. 8mm is a very thin pipe.
If it works ok, and it doesn’t bother you that much (which it seems like, since you ask the question). Just clean it out. You will see an improvement to more then ok.
Only replace it, if it bothers you, and you are happy to pay the costs for a complete upgrade. Pipes and rads and boiler and all.
@@harunyahyadotorg James thanks for your reply...I got it wrong it's a 10 mm piping. Can you do a video on fitting a Thermostate to 10 mm rads. Should I replace the radiators or remove the internal spreader tube? Both microbore pipes enter the Rad on the same side. 
Kamco tie beste
Do you have to turn the mains water off before you remove the radiator.?
no
Perhaps this is a thick question, but I assume the pipes don't get flushed then?
1. As you empty the system. Allow the water to stay on. The pressure will flush it out a bit more for you.
Or you can 2, empty and refill and then empty.
Or 3. You can insert sludge cleaner (1 litre tub, for ~ 100 litres / 10 rads) and leave for 1 month as a pre-dose, (preferably in the winter, when the heating will be on, 1-2 hours a day). To clean and loosen the sludge from all the radiators / pipes / contact surfaces…. ( a bit like leaving the dishes / items to soak for a bit, before washing them).
Then after a month, empty the water from the system. Then refill with water (emptying out all the air from the rads, to wash out all the sludge once again as a rinse, then finally refill with water, and insert inhibitor 1 litre tub for 100 litres / 10 rads (as a minimum).
I have 18 radiators in a house that I am doing, so I use 2 tubs of sludge remover, then to empty and then to rinse out, and then finally 2 tubs of inhibitor (to prevent further and faster corrosion of an old system).
Thanks
@@harunyahyadotorg Brilliant. Really appreciated. Thanks.
I assume (rightly or wrongly) you have fitted a one way water check valve in the mains water supply hose?😲😲 If not, magnetite and fithy water could be sucked backwards!
Water only flows out the mains (due to the pressure going out). Not in. What can potentially suck anything in? Nothing!
If there is any risk of this occurring then yes check valves are required by regs or yes with a depressurisation of the mains you can syphon shite back into the potable water supply... not good.
where you based
Flushing rads is easy in comparison to removing radiator without destroying your carpet or other floor coverings.
Where does the metal dust come into the radiator?
Rust
Oh….I was told it was EASY to do! 🤦🏻♂️🙄
Ill pay someone to do it 😆
Since YOU have a rubber mallet, why are are you using the inferior claw hammer!
Probably to show you an alternative.......as he'd already said.
The metal on metal contact sends more of a shock and vibration to dislodge the corrosion. Hit a rusty piece of iron with a rubber mallet and a steel hammer, yoll see the difference.
Leave it be.If your radiators are hot no need to flush.I.Iused to flush my radiators every two years.Took themt off the wall and flushed them in the garden 8 Radiators various sizes.I haven;t touch them for twenty years the radiators are 38 years old.I do use rust inhibitors in the system.My system is micro bore.
The advantage of your system is that you can turn it upside down, the water will fill up the radiator, then through the other way.
1. As you empty the central heating system (radiators and pipes etc). Allow the water to stay on. The pressure will flush it out a bit more for you.
Or you can 2, Empty and refill (periodically to increase and release the pressure) to empty the water out.
Or 3. You can insert sludge cleaner (1 litre tub, for ~ 100 litres / 10 rads) and leave for 1 month as a pre-dose, (preferably in the winter, when the heating will be on, 1-2 or even 3 hours a day). To clean and loosen the sludge from all the radiators / pipes / contact surfaces…. ( a bit like leaving the dishes / items to soak for a bit, before washing them). The longer you soak them the better but 1 month is enough with the heating on 2 hrs a day as an example.
Then after a month, empty the water from the system. Then refill with water (emptying out all the air from the rads, to wash out all the sludge once again as a rinse, then finally refill with water, and insert inhibitor 1 litre tub for 100 litres / 10 rads.
I have 18 radiators in a house that I am doing, so I use 2 tubs of sludge remover, (for 1 month, heating on 70 degrees for 2 hrs a day) then intend to empty the system completely out again and then to refill and rinse out completely and then finally refill and add 2 tubs of inhibitor (to prevent further and faster corrosion of an old system). I hope it to work… let’s see… As that’s the best I can think of without pressure washing (£350, November 2021 prices) the system out.
Thanks
How do you add sldge cleanr to the system. I don't see the way to just adding it in my system. Unless you mean one by one radiator?
@@pistopit7142 if you have a vented system, you can close the tap into the expansion tank, release some water from the system from the lowest point, add the cleaner into the expansion tank, bleed the system, turn the water to the expansion tank back on. Not sure with a non-vented system.
Should flush in both directions not just one way to flush better
Not as helpful for realistic scenarios where people dont have all these adapters lol.
Just buy a new radiator, safe all this trouble.
