Thank you for taking the time to make and share this video! 😊
Thanks for watching!
Appreciated the explanation of the different cleaning products.
Glad it was helpful!
Great video. Thanks so much.
Get a £20 massage gun with the foam ball end and use that to vibrate the radiator, cheap alternative if you don't have an SDS or the attachment is too expensive.
Great idea, thanks!
Great Idea where from ?
@@darrenforward8277 I tried replying but my comment seems to have been deleted. Any massage gun with the ball end will do.

👍 Some very good tips - thanks. 😊
Thanks Errol!
Thank you for sharing this video I appreciate your time 🙏🏻
Thank you for watching, very appreciated!!
Just confirming - when you said you were going to close the lockshield on the drain off to allow water through the radiator…did you mean open it?
I actually can’t remember now, but if you’re doing this method you can work it out on the fly. Thanks for watching!
10:28 i like how it has dual valves , incase one fails ,my combi boiler only has one on its refil loop which is pretty bad if it goes tits up
Thanks for watching!
Fantastic video thank you!
Thanks for watching!!
I wanted to ask if it is easy or difficult to install central heating as a beginner who has finished the 4 month school for hvac systems, where should we base ourselves
Depends on the complexity of the system and your skill set really
Best yet 👍
Thank you!
Really like this idea, I was thinking of getting one of the drain cocks open all the time and flushing the water through. Would I still need to turn off the thermostat and lock on each radiator in turn, I pressume to keep pressure up in that single radiator to remove the gunk?
Thanks! Yep you’ll need to isolate all radiators and open one at a time to get a good blast through. You only need to close the valve on one side of the rad to turn it off though, no need to do both sides. Thanks for watching!
Could I just add the inhibitor directly in to the magnaclean filter since I need to clean mine off anyway? let it pump around a bit then add whatever is left?
Also, nice pipe work :)
Yep you can use your magnaclean as a dosing pot. If you don’t have a towel rad you can put a funnel in, using the magnaclean is a good alternative. Thank you! And thanks for watching!
@@TheDiligentDIYer1759 Cheers chap I'll sort that out tomorrow then. Have a great christmas :)
Thanks, you too!
Thanks for an informative video. When you've treated with X800 for an hour on full heat, we have a drain point at one of the radiators. Should we just drain the whole system and then refill the whole system? Not sure how to 'blast' one radiator at a time - what is the sequence exactly - are you sending refill water to one radiator at a time, then draining system each time and closing off to do the next radiator, before finally refilling the whole system?
You need to flush the X800 out, just draining the system will still likely leave a lot of cleaner sat in the pipes. Easiest way is to turn all the radiators off at the lock shield or trv, then turn them on one by one, with the filling loop turned on max and a drain off open. The best way though is to take your filter off and put hoses onto the flow and return then flush from there using the hose pipe. If you haven’t got a filter though, you’d have to cut tees into the flow and return by your boiler.
If I drain down to remove cleaner, could I the refill system and drain down again. Would this remove all cleaner from rads and pipe work, rather than doing each rad individually? Thanks
Unlikely you’d get it all out in my opinion, you need the flush to get all the rubbish out of the system really
Thanks, my boiler and magnacleanse filter are in my loft and not easy to get hosepipe up there. Can I do a mains flush using a hosepipe attached to a radiator. If so can you explain what I have to do. Sorry to be a pain, I appreciate you are probably v busy.
Despite having the ch system flushed when a new condensing boiler was installed I still need the pump on maximum speed to reach the required circulation for the boiler to function. Do you think using the x800 would help or do I need a powerflush?
Seems odd that you would need the pump on full just to get the circulation needed, you may have a blockage or pipes that have a lot of debris in them. You usually get the most build up in any bends just before the pump, you could try cutting out a short section of pipe to look, clean it out and solder it back in using slip couplers.
If you haven’t got a magna clean, I’d fit one of those on the return before the boiler too. Thanks for watching!
I’ve got a combi boiler is the process the same by leaving the filler loop on and letting it get full whilst draining it? Do both lock-shield and trv need to be off or just the trv will be sufficient? Do you use just a normal drain off point for the water to just come out? I’ve only got one drain off point on a 15mm copper pipe by the front door will that work?
Yep same process with filling loop on and drain open. Only need to turn one rad valve off per rad, not necessary to turn off lock shield and trv. Yes your drain off will work. Thanks for watching!
I have underfloor heating as well as numerous radiators upstairs and down. Does this complicate things when attempting a system flush?
You might need more cleaner as you have a lot more water, but the principles are the same. Thanks for watching!
Do you drain the system after finishing with the cleaning solution? You didn't specify but I'm assuming you would do this before adding the inhibitor unless I'm mistaken, please let me know.
Yes you effectively drain it all out when you do the flush. The idea is that you put the cleaner in, run the system hot for a while, that lifts all the dirt into a suspension. Then you flush with mains water, one radiator at a time to get all the cleaner and dirt out.
@@TheDiligentDIYer1759 cheers. Appreciate it.
At 8:22 you talk about flushing both the flow and return as opposed to just one- is there anywhere else I can find information about this? Does this only apply to the radiator which is being used to drain down the system? This is the only bit I'm unsure about in your otherwise very informative and helpful video.
I'm dealing with a very clogged up central heating system so I want to get it cleaned up as well as possible and this seems rather relevant to flushing as effectively as possible, if you could extrapolate on this I would appreciate it- I've not seen this mentioned anywhere else. Thanks.
That was more unique to my system design where the filling loop is on the return and I was draining off the return, so I don’t want to just drain that half of the system, and ignore the flow side. It will depend where your fill and drainoffs are located. You essentially want the water to go up one way and come back the other to a drain, in order to flush the system out. Sorry if that wasn’t helpful!
@@TheDiligentDIYer1759 I see, thanks!
My hot water is luke warm, what could be the cauad of this?
Very difficult to say without a lot more information or seeing your system. Probably best to get a plumber round if you’re not able to work it out. Thanks for watching!
@@TheDiligentDIYer1759so mine is a vaillant ecotec combi boiler. W
The radiators heat up fine but the hot water from the tap is not piping hot, but just luke warm. Does it sounds like the heat exchanger plate that has maybe scaled?
Yes you’re probably right or a broken sensor, either way I think it will be a job that needs a professional in unfortunately
@@TheDiligentDIYer1759 thanks mate. Appreciate it. Keep the content coming!
Brilliant Vid ! Are you a plumber by trade ?
I’m not in the trade at all actually, just an over enthusiastic DIYer. Thanks for watching!
my parents used to fluish their own, but it takes hours , cheaper to hire a pro to do it IMO, time is money and the pros add in the chemicals in
If you have money, yeah, hire a professional. If you don't, like many of us, DIY.
@@jakebarnes3054 just do overtime
Not every job allows over time, and some people enjoy doing things themselves too.
Most so called pro's are doing the job to make money not to do the job properly
X800 is not recommended unless you thoroughly flush out.
Agreed, but i do in this video. Thanks for watching!
Although i applaud you on one hand, i would NEVER advise anybody to mains flush their own heating system for various reasons, yes, you might have some money, but just how good of a job are you actually doing without knowing the full ins and out of a heating system, plus, without having somebody check your system could actually stand up to mains pressure, you could cause more problems than your solve, thus needing and engineer to repair anyway.
Like i said, informative, but not recommended
Thanks for watching!
Dare you to turn that pump valve off
No reason to - thanks for watching
Ive just had the gas people out, theyve quoted £850 to flush my radiators 😤
That is a fortune! Definitely a job that can be done DIY. Thanks for watching !
@@TheDiligentDIYer1759 I got home and used the massage gun technique 👌 🥳
I hope you have knee pads in! We never wore them when we were younger but I'm struggling now after 50 years plumbing!
I've just had a quote of £880 for a flush. I will be doing my own 😮
Having a professional carry out your flush is the best and safest option, yes, you MIGHT think you can do it, but, I bet you wouldn't be doing it properly.
Some companies quote £100 per rad, which is ridiculous, but it is a costly job, ideally most system should take all day, which is labour, normally a flush cost between £500 -£600, but that's all time dependant.
If you suddenly rupture a joint because of excess pressure, will you fix it?
What the hell you got on your feet bro???
Crocs haha, they are my garden shoes, i wouldn’t wear them out the house. Thanks for watching!
