Hot water spluttering since installing Flange

[Doggit]

Something definitely looks wrong there. Is that pipe on the right coming up from the hot water tank. Where's the overflow pipe.

 

[polesapart]

Yep, that's also a good way. I don't think the flange is the issue, just a regular airlock.

Right, go and look at the installation notes on post 10, and then come back and tell me where I'm wrong.

Yes, I haven't touched them and the overflow is further on to the left out of shot.

Yep, easier said than done!

Do you think If I shut of the water and then opened all the taps starting downstairs to up would make a difference? tad annoying this Plumbing lark

 

[Doggit]

I give up.

I give up.

Why's that Doggit, don't leave me to be honest so have I nearly

I put my finger over the mixer tap hole and turned the hot on whilst I then slowly turned it to cold, I think it's made a difference not spluttering as much now - mainly the bath mixer taps are the issue.

Persist with this. Cup your palm over the kitchen mixer spout and open first hot then cold so that cold water under mains pressure flows back up the hot pipework for a few minutes. Try it with bath hot tap both closed and open.

I will, determined to sort this I don't think I am miles off cracking it to be honest Bath Taps are not too bad now but room for improvement - others are ok.

Alright rvp, one last try. You showed us a picture of the pipework in the loft, but as well as being fuzzy, it was either the wrong picture, or it showed part of the problem.

You've taken a hot water feed out of the side pipe on the flange, and then meandered it up through the ceiling. Now the picture that you took, should have show the pipe coming back to feed the hot taps, and then up and over the feed and expansion tank (as per the instructions in post 10), and that would then let the air escape. So either you haven't shown us the right picture, or that picture shows that the pipework isn't right.

Ok, just for you Doggit

I've been up to the Gods to get a few more pics hopefully better quality and shows the set up better - I have not touched the pipe work in the loft.





Any better?

 

[Doggit]

Well they are much clearer pictures, but still don't show that the pipe that carries the hot water from the tank, then rises up and over the expansion tank to take the air away.

It's in the 2nd picture, covered in insulation to the right of the larger cold water storage cistern on the left

RVP ... If it was fine before and all you have done is added the flange and made that slight change to the pipework to accommodate the dedicated shower feed out of the top of the flange then it's nowt to do with the pipework. The only thing to have really changed in that setup then is the flange. I'd be looking there first

 

[Doggit]

Thanks for that Madrab; and my apologies rvp, mistook the bent pipe as the hot pipe.

That's correct Madrab.

I do now have an extra elbow connecting the Flange as opposed before it was one like one elbow then straight down into cylinder.


I know it's a minor change but maybe that extra elbow is the cause, ideally I wanted to come off the wall>elbow>into side of Flange but couldn't get room to cut the pipe.

 

[Madrab]

Nope, an elbow shouldn't cause that much turbulence in the flow.

That being said though, I'd be tempted to swap out the flange for another type, a surrey perhaps. That would at least allow you to remove the extra elbow and put the pipework back to the way it was removing that from the picture. What made you use a warrix in the first place, the moveable feed?
