Her good video Alan. Thanks. I watched lots of your content before recently passing my acs and becoming gas safe. I'm a new engineering having retrained. Thanks for helping us guys who are less experienced :-)
This is the most amazing and interesting video I have ever seen on central heating flush because the presenter catch my attention and delivered too many information in short time. Thanks alot Alan for introducing this gem steven to all of us. God bless.
Brilliant video. I’ve been power flushing in Ireland for the 7 years. If I had this video back then it would of saved a me some heart ache. 😂 well done.
When I'm doing a Power Flush the first tool I take out of my van is my Parkside (Lidl) wet n dry vac. It's almost the most important component in my Power Flush arsenal. It has saved my bacon on numerous occasions.
Thank you for explaing the process as I need to power flush my system raditors some hot at the top and cold at the bottom I now under stand the process better. To complicate this I am made to understand the pipe is smaller than should be used for the flow from the extension to the main part of the house. Thank you for explaining.
SM/Dual fuel engineer here...looking to make the transition to a heating engineer in the next year or two, so just learning the basics and getting some out in the field experience. Great video guys 😊👍🏻
Thanks, really interesting video. Can I ask how you make a decision, for example with old radiators, on whether you flush or bite the bullet and replace rads?
Thanks for the Info, regarding the radiator valves, since every radiator has them thus creating restriction to flow and potential blockages what difference does it make connecting direct to the valves?
Hey allen thanks for the video really appreciated i prefer using this method with the camlock and cutting 2 tees in underneath the boiler if possible and isolate boiler flow and return isolation valves so no debris goes into new boiler or preferably flush before new boiler goes in, some great tips mentioned here 👍
@@AllenHart999 a very old kamco doesnt have a heating element tho does the job i dont do much installing these days mainly service + repair +plumbing repairs thanks allen 👍
No aday after cleaning with machine and chemicals, i use a kit that connects to mains water and allows me to reverse the flow just like power flush machines do, but a lot more powerful and sorts out harder blockages. Sometimes i don't even use the machine as the system is already topped up with chemicals, it then takes me 3 hours to complete 12-15 rads system. Magflush solutions based in London.
I sometimes use a Rad Hammer to dislodge stub Magnetite cold spots. You can use a rubber mallet, as an alternative. But the more blows per minute. The more effective, the results. You can see sudden gushes of black sludge coming through.
I just had a British Gas engineer replace the heat exchanger in my boiler. The engineer recommended a power flush because he said the water was very dirty and it became like this because someone left the filling loops on the boiler open. This problem was affecting my hot water as it only remained hot for the first 7-9 seconds after which it became freezing cold. How can I maintain my boiler to stop this from happening ever again?
we are planning on getting a new boiler & replacing the 40 year radiators that are in use but not the ones we don't use currently (which is 10 of 15) - in your opinion do you still think a power flush is needed when you are also replacing the in use radiators ? - wont most of the circulating system sludge be removed by just replacing the radiators & draining down the system ?
Thankyou very much brilliant video- especially about remove the inline filter under the combo boiler I did this and clean to increase flow when showering - Also could I just remove one radiator and connect a mains water hose to one side and hose connection to other side of rad and turn tap on to remove magnetite and rust from system - as i haven’t got a flushing machine just a diy guy? Cheers Steven
Hello Allen, its a big request if you could put a video on how can we connect powerflush machcine, along with Adey Magnacleanse , just to explain how is connection pipework made please
Great idea to keep flush machines outside, keep off the nice new mono lock. I’ve got an old 50 gallon rubber storage tank ( remember them )that I put the flush machine in this act’s as a great safe should any mishaps or Spillage happen. Putting it in the costumers bath or shower even with a dust sheet I don’t think you would get time to switch it on before you were shown the door.
Great vid Couple of questions...... I use x800 but I noticed you don’t have a bottle of that on your shelf. Any reason why? What about agitation with the appropriate tool fitted to the drill? Where can I get longer high pressure hoses from?
They were just the chemicals we had, we just tried to have all the different brands on there, didn’t want to promote one brand, I like x800 and also the new F8 is very good, we used to use deposit remover many years ago, The drill agitation tool is very good although I used to use a runner mallet,
What happens when power flushing does not clear blockage? Had a boiler upgrade last year but could not get heating to work upstairs. Boiler installer advised a power flush but blockage remains after two attempts. The system is 15mm copper and over 40 years old, iron radiators. I am now assuming I need a new heating system do the copper pipes need to be replaced or can they be unblocked? I am guessing the radiators should be replaced due age. Dublin Ireland
Hi alan I have new Boilar installed and they didn’t do hot or cold flush for the system when I asked them they said it’s no need for it the magnet cleanr will do the job
Hi There, Good video. However, tried to submit a request for a quotation at the Power Flush association website and was unable to as the site isn't working.
Pete please please make sure you have nothing bye passing best way is to turn off all rads , you should have no flow from your return, also don't forget to flush the plate heat exchanger or coil.
You could still get a corrosion build up, from other components. Like your pump, heat exchanger, even copper. Flux & chloride, within the system. Makes the water acidic.
Hi Allen always use the Magna-cleanse magnets with the agitator on the rads, how do you think this compares to the flushing machines ?? Great videos by the way !!
@@AllenHart999 I've got a fernox powerflush machine and a magnacleanse. Never used both together. I was going to connect magnacleanse to the magnaclean connections then connect powerflush m/c on the flow pipe. Then I have the best of both working together. I emptied a filter yesterday as bad as the one you showed last week.
Any good flush machine should be capable of 0.75>1bar operating the pressure switch, allowing the boiler to heat. The challenge is if using chems not compatible with alloy and should not be flushed through the boiler. Either heat the system before looping out the boiler or invest in a secondary heat device. Norstorm are a great unit.
Hi Allen, decent vid but I have a few questions. Have you any good tips on flushing microbore ? I've found powerflushing pretty innefective if badly blocked regardless of where you tee in. Also do you think the filters reduce flow rate too much, is magnets dangled in machine a better way ? Only thing I didn't agree with in vid is machine in bath asking for trouble in my opinion. Always outside if possible get your steps in and build a dust sheet tent if it rains.
Treat microbore no different from a normal system. I have been powerflushing for 20 years, done a couple of thousand. he is waffling on a lot of nonsense despite saying a lot of good stuff too.
@@AllenHart999 So what would be needed Allen? that was like a builders quote the big suck in of air and then well that will depend. IT was just a ball park figure i asked for .
Hi Dennis Thank you for the question. Micro pipe can be powerflushed but not always easy. once the system is clean then i would clean the filter each year on a service. Thanks.
I wish this guy could do my system. Plumber said my system is completely blocked and can't do anything about it. If anyone can do it this guy can. I'm in Swindon. Message me please.
How many disasters have you had? I.e fitting blow off due to power flushing underfloor or similar? So systems that are 90% installed in plastic are less likely to have rust, Thanks
I found these uk.rs-online.com/web/p/hose-couplings/0307213/?cm_mmc=UK-PLA-DS3A-_-google-_-PLA_UK_EN_Plumbing_%26_Pipeline_Whoop-_-Hose+Couplings_Whoop-_-307213&matchtype=&pla-297741544951&gclid=CjwKCAjw6fCCBhBNEiwAem5SO9Yt09ga2Xx9XVo5oc6x_hkDyNUR3dgs5lr9thM9Hd8y4ZyQekY-hBoCbiAQAvD_BwE&gclsrc=aw.ds
Does the location of placement vary on vented un-vented or sealed systems? I really don't understand why some installers get hyped with the amount of magnatite that collects in magnacleanse filters. There really shouldn't be that much rust in system. Secondly some engineers changing plate to plates on an already dirty system leaving at it that. The new plate will most probably incur the same blockage. At least suggest a system cleanse. If you have rads over 2 or 3 floors how is it that you keep them half full? Does gravity not bring the water to the lowest point? Meaning the lowest Rads are always full. The most important thing I find is to write up a contract and get the customer to sign it. Old systems tend to bring up pinholes in Rads. You get the odd complacent customer. Believe me you don't want that biting you in b**t Great information there guys. I picked up a good few pointers here. 😉
Hi Ray. Thank you so much for the feedback. Changing plates are almost pointless on really dirty systems as you say they will block up again. if you fully drain the rads and then refill you will trap air in the top of the rads and this will help you clean it better. Remember you need to open the air points when you drain it though. Trade help do terms and conditions for free on there app th-cam.com/video/32Fq11ubjps/w-d-xo.html Thanks.
