- If your Combi boiler has stopped working and needs re pressurising, finding that the filling loop needs to be connected first, can be a hurdle. Topping up the Comi pressure also shown

4 years on and you've just stopped the need for me to get a plumber in!
Trade isn't cheap, but education is free! Cheers for the video
No problem.
Thank you so much for this, I’ve just moved into a new flat and the boiler pressure was 0. This was so easy to understand, and now I have hot water back! ☺️
You're very welcome!
No hot water this moning & I noticed the pressure was 1/2 a bar, then i remembered saving your video on this subject to a playlist.. Although my loop was on. there are no levers to turn the pressure up but i noticed a large screw in the flow pipe so as soon as i slightly turned this i could hear the flow and 👌 the pressure is now 1 1/2 bar as recomended by you. Thank you very much for this valuable tip Mr Dereton. 👋👋
No problem pleased you sorted it.
Thank you so much! My boiler stopped working soon after installation. I knew I had to bring the pressure up, but did not know what the loop (which the workmen had left on the side) was for! I followed your video bit by bit and everything is back to normal!
No problem.
Just came along your video as my boiler was flashing 0.0 and my housing was not being helpful at all. Thanks for showing me how to connect the loop as I didn’t even know it was on top of the boiler you explain it well and clear keep doing a fantastic job 👍
Thanks 😀
Thank you so much for your video it helps us single mum to fixed the boiler when we need help or of no one is around. Your video is so useful i thank you from the bottom of my heart 👍👍👍👍
You are very welcome
Life saver!!! Had an appointment with my boiler ppl today to come out and put pressure in boiler bcuz thy removed the pipe just for them to cancel today with another appointment earliest being Monday it’s -8 in my house atm so this video just saved me THANK YOU SO MUCH!!!
Excellent!
Thanks for this. We have a problem with our mains water quality and the water company asked us to check our filling loop was OFF. This video makes it clear what they were talking about. Apparently germs can grow in a loop and contaminate your tap water if you leave it open.
No problem 😊
Thank you so much, that was clearer than any of the other videos including my boiler's official site.
Thanks Rani.
I've often wondered if the boiler would blow up if you left the filling loop on! Thanks - really informative
No a safety valve is fitted.
Thanks for your easy step by step instructions, and for answering the question about too much pressure/boiler blowing up!
Glad it was helpful!
You have just saved my Christmas Day with this video, Thankyou so much 😊
No problem.
Thank you. Saved my day on a weekend calling for engineers. Cheers 🍻
You're welcome!
Legend mate you saved the day! So clear instructions thanks so much!
You're very welcome!
Much clearer than ay other video. Very concerned not to do the wrong thing, but this was so easy. Thanks
You're welcome!
Thank you, this video helped us 😊
You’re welcome 😊
Brilliant video and well explained!
No problem.
Thank you, this Video has really helped
You're welcome!
YOu are brilliant......thank you so much!!!!
No problem.
Very clear video! I hope you do more DIY videos
Thank you! Will do!
Excellent video, brilliantly explained, thank you :)
You're very welcome!
Cheers mate, saved my uni house here
No problem
Thanks! Just what I needed! Liz
No problem Liz.
Thank you very much for the video. My boiler is heating up now.
No problem hillary.
How do you tell which 2 pipes to connect? There are a few with taps under boiler! Watched loads of these vids and not one says which if the loop has been left disconnected
I will do a video for you on it.
@@dereton33 very kind! We're in an emergency so I'm just going to try the two I suspect are the right ones !
Hi I have a boiler I did this and went to 1.5 and started working, however after a few hours I heard a loud noise like a drone and vibrating, and the pressure going to 2. Not sure what I’ve done wrong!
Valve left filling to long shut off after reaching1.5.
Hi. Can you help me please. My worcester boiler dropped the pressure to 0 and i tried on youtube but cant find a solution. It doesnt have the keyless nor white key.
You will have to find the cause of the leak first. You may have a filling loop elsewhere.
Hit there, I don't have any taps on my filling loop so I don't know what to do. My pressure is down and I went to top it up and saw that there's no tap but above the loop and higher up the pipes under the boiler there are two taps.....help! I don't know whether I turn the taps of use a screw driver on the filling loop. Sorry if this sounds ridiculous....
Don't turn either of those. If the filling loop is connected there will be vallves either end.
I want to change the filling loop on my boiler as even when locked off water seems to be creeping in adding pressure. Do I need to drain the system down or just shut off the water mains?
Just shut off the mains.
@@dereton33 Thanks very much easy job then
Very helpful, thank you.
You're welcome!
I was sat on the sofa with my mini schnauzer watching the video and at the end my little one jumps to the screen 😂
Ha ha they know there own.
What do I do if the valve on the boiler side is leaking? I am confident to replace it but concerned if I take it off the contents of the heating system will empty on the floor. Is this an empty and refill situation?
Just loosen the valve and let the excess water run into a container. No need to drain unless there are rads above the boiler.
@@dereton33 most houses have radiators above the boiler though. Could you just shut off all the radiators in the house and allow excess water to drain out?
When you repressurise the boiler do you have to switch it off at the mains first and then repressurise or can you do it when the boiler still has power? Thanks in advance for answering.
You can leave the power on.
Big thank you!
You're welcome!
Great video Dereton33 thanks. I have a problem at the moment where the boiler pressure keeps rising too high above 3 bar! I've been trying to turn off boiler, isolate it, drain. Then when i turn off the isolation valve the pressure immediately rises on the bar gauge almost into the red. I turn the boiler back on and within a few minutes it's at 3 bar or higher again. Do you think it's a faulty filling loop or could it be something else? I have a Vaillant Ecotec boiler by the way.
Try disconnecting the filling loop once you have the correct pressure in case one of he filling loop valves is letting by. Sounds faulty.
Hi I've ordered a new loop, so will able to reset my boiler, but is it possible my boiler only has one valve to turn instead of 2?
It may have yes.
Thanks - that would make sense - but stupid question but I am going to ask it anyway - I would still connect the loop in the same way at both ends?
Hi good video. where can i get one of those little black valve taps, for a old worcester boiler. seems the guy who serviced boiler has broke one of the two, so cant adjust pressure as before. Thanks in advance.
You will have to try Worcester.
Hi Al, what do I have to do if I have to replace both taps and the hose in between? Do I have to de-pressurize the system?
Yes and drain a small amount of water out of the system.
@@dereton33 thanks Al 👍
very clear thank you.
You are welcome!
Thank you
You're welcome
Nicely explained. Is it a problem putting air in to the system as the loop won’t have any water in when you connect it.
No that one is overrated.
@@dereton33 thanks. I’ve just refitted a new one and apart from a few air noises all was good. The air noises soon disappeared after running the taps for a bit.
Excellent 👌✨👍
Thank you! Cheers!
i cant hear no water being released when i open valves, pressure at 0, help
One of the filler valves is not on.
Hi mate . Good videos as always . My tenants boiler has pressure valve replaced and new expansion vessel due to leakage . He did not replace the filling loop which he told the tenant is blocked. Hence the water overfilling and pressure in increasing to 2.9 bars . There is also lots of loud rumming drumming noise from the pipes and water leaking into the outside from the boiler pipe . Is the air in the system as well as the filling loop an issue or something different.
The PRV is letting by. I would get an engineer in to look at this boiler.
Do the radiators need to be bled at all when topping up the pressure?
No.
As a qualified plumbing and heating engineer for 15 years the answer is yes u should bleed the rads after topping up, wen you bleed the rads the pressure will drop again so need to top up after bleed rads , top up to 1.5 bar ,also if you find your pressure dropping al time that indicates a leak sone were in heating system shouldn't just keep filling it up
Thanks for your videos Dereton 33. Silly question here, but just to confirm, is the filling loop connected to the water inlet pipe and central heating flow pipe? Thanks
The maims inlet pipe and return heating pipe
@@dereton33 Brilliant. Thanks for that. Keep up the good work!
Hi Al, thanks for the video. I identified the pressure loop on my boiler with the two black knobs but there is a problem: one knob turns freely but the other is fixed (seemingly on purpose). Just below it on the pipework is a slotted value, like on an isolation valve: should I use that instead of the second black knob?. Also, my boiler has two pressure gauges, one digital and one manual (like yours). Both show slightly different readings. Is one more accurate than the other? Also my radiators have a very simple air venting mechanism, just a nut and a slotted nipple, seems odd? Finally I would like to send you a couple of ££ to help keep the free content flowing - how? Cheers.
Hi Steve, you will need to free the second black knob as they stick shut. Take the black knob off and use a small adjustable spanner to turn it, once free you can put the black knob back on. Use the manual gauge for the pressure reading. The rad vents on the rads are quite normal on certain makes . My donation tab is in the description under the vid, thanks Steve.
NICE!!!
Thanks!
Thanks for I don’t have a key for the boiler and my pressure is been on zero for months
Sorry to hear that
It’s sorted thanks to your video I’m really grateful
Wonder why the plumber didn't connect them in the first place?
Some do some don`t.
Water regs are to disconnect
Paul W correct
Water regulations are to disconnect
Looked a bit blustery outside at the end,
Cold too PB.
Where is the main water inlet
It is the 15 mm pipe. 3 rd pipe from the right.
Ktf
Woz dat mean
Don't get me wrong
Which valve did you turn to increase pressure? You showed the gauge going up BUT not showing which one did you turn it on? Poor video. Do it again
Perhaps you would like to do a video on it as mine was so bad.
@@dereton33 don't be harder on me. I'm not a plumber but your boiler is exactly the same as mine. I had to repeat several times to see which valve you opened to add pressure. I like your video but you let me down on valves. Help me not trying to be harder on me. I hope this will help what I mean.
Kind regards
Thank so much you just really helped me!
No problem
