Worcester Greenstar - How To Change / Replace The Return Manifold / Block / Unit 

Even though this post was two year ago, I finished my job today according this video step by step. I watched many times for practicing, Thank you!

newly qualified as gas registered . and first job is this leaking. watching this hope i will be ok 😂. thanks for great video

Thanks so much for these videos I really wasn't sure whether I could do this job as it looks quite intimidating or so many connections but with the help of your video I got it done took me about 6 hours but I got it done I did do some other pipework for a power flush so I'm going to do tomorrow

Class video, never done one until today - followed it step by step. Thank you very much you got me out of the shit today and I learnt a thing or two.

Hi, Indeed a great video, and very well put forward! ...the only thing I did notice, when handling the main body, the small valve came out and went under the boiler unit, though you did find it and placed it by your grease tin! ...if this boiler is to be used again, this will need fitting! ...again, great video.

As a installer not a breack down engineer I was able to follow this video and do the job thanks again

Really great video, takes the guessing out of what to do next. Had to give a recent job over to someone else as I didn't have access to the video. Now I would be far more confident to attack a manifold replacement.

Brilliant video, my return manifold is leaking, so this is really helpful.

really helped me there pal thank you took me 3 hours to do before and 45 mins to do watching this thank you

Got one of these to do tomorrow. Been told they're a pain. Ty for the vid m8 😊

Changed my first one on Friday thanks to this video! Only thing I did differently was remove the cold pipe first before doing the pump clamp etc which was a lot easier, thank you again!🫡

Thanks for sharing this mate. Absolute legend

Thanks for your help and efforts.

What a Brilliant vid....Top Job! Helped me out loads.

Love these videos, keep them coming 🙌🏼

Great video 🙏 thank you

Like the video mate. Subscribed waiting for more videos

Brilliant video!

Legend just fixed my outlet manifold 🤟👍

Brilliant vid helped me out so much👌 after fitting new manifold flow on central heating gets hot when run dhw the pipes hot but not radiators. Had new diverter on new manifold could this be sticking?

Excellent video, well explained

Great video, wish l seen it before, don't my first r h b last week but took out left hand out aswell as one unit with pump attached, took a while to realise the orv was stopping the unit from coming out .Still got the cuts to show for my troubles 😂🤣

Top man..much appreciated 👍👍👃

If you remove the bypass pipe from the return manifold ( rather than the left side of the block), you don't need to remove the water pressure gauge or the expansion vessel braided hose from the pump body. Just pull the pump off the return manifold and sit the pump where the condensate trap normally sits. This came from our tech, who said you can cause damage when removing the pressure gauge and braided hose. I did my first return manifold 2 days ago and did it this way and it went without a hitch. Your video was a huge help, mate. I only had to watch it twice and was able to change the return manifold in good time. I've subscribed to your channel and will get a look at your other videos 😊

Good oh I will be doing this today,thanks for that sir

Hi Notice u have had a couple of criticism comments . Do not get discouraged by the ignorance of some people. The only way to learn is by some one teaching u or self learn. So get an old boiler and strip it just the way ur doing cheep up the good work My only advice is there’s always a tool which makes ur life easier to do the job so invest in that tool

Later type unit as the longer syphon, new type fan fitted, overall that visually looks in good condition still, no visible excessive heat damage to the heat cell, and easier when they are dry too. good vid tho. Nice dark orange staining on the inside of the pump connection part of the return unit, and rear lower seal, defiantly a water quality issue on that system it was fitted on.

I had an absolute nightmare with one of these earlier today. I found it almost impossible to get everything lined up again. When I finally got everything back in position and tightened up again, I turned the mains water on and water was still coming out of the heat exchanger/return unit connections. I had to leave it till tomorrow. Absolute pain in the hole.

Do you not need to take bypass restrictor out of old manifold and use in the new manifold

Your solenoid looks really high.. mine looks really low.. I commented on yoir other video just. I replaced the right hand unit/turbine, refilled and I've got a mostly off blue light and a 2 flash red. No ignition. Its locked off... i followerd everything you said.. Any ideas, Sir?

The most disastrous boilers to challenge a part

Not a bad example. You did miss a few tip points in my eyes. But I suppose that's because it was a scrap boiler that's not going to be water tight again. But not a bad reference for someone who hasn't done them before. Just to say, I've changed hundreds and hundreds of these. So I do know what I'm talking about

how on earth did you put that return pipe back in so easily, the one under the drain off, took me a lot of sweat, after about 30 mins I gave up and used the original o ring and still it was a right pain

I don't see much reason to take gas pipe out? Can make can of worms
