Gas pressure question

[Wormwood]

I've had a tech survey for a new boiler and they reckon the gas pressure (at the boiler) is too low. Could this be caused by an old/knackered gas meter?

My meter is a 1985 Parkinson Cowan. National Grid put a new regulator on and the pressure immediately went up by 4mbar - but they didn't change the rest of the meter (i.e. the big bit ).

TIA.

I think this thread should be closed.
There is too much gas related info being given to a diy'er who should just employ a good gsr to install the new boiler and update the supply pipework as needed.

 

[GH77]

He already has, just reassuring him that his GSR is correct, why he's correct and that he's not being ripped off

Agree with chalked , this should have been closed yesterday

I am NOT a DIYer!!

I've already said several times that I have no intention of doing it myself and that I have and will use a qualified gas installer.

Read posts 16 & 21!

Is that clear enough for you?

I will not say it again.

 

[Wormwood]

I would get no 2 done first and see what you get

Yes, I think you're right. Then no 1 if it's still too low. (My meter really is ancient, spiders crawling out of it, etc, etc).

Btw, I reckon the 22mm-15mm reducer is closer to the boiler than I thought (I had a closer look last night). The 22mm comes out of the meter and goes straight back through the wall horizontally. After 10 inches, it disappears behind the plasterwork inside the lounge.

Here it must either a) turn vertical until it reaches 1st floor joist level - or b) go off in another direction.

Assuming a) is correct, it must turn horizontal again and run through the joists, over the hall, over the downstairs toilet, and into the kitchen, where the boiler is. Then it turns vertical again (so it's now pointing downwards), reduces to 15mm and runs down inside the plaster to the boiler.

All I have to do is find the point where the reducer is - my guess is directly above the boiler at 1st floor joist level.

Mr Wormwood , you are out of order disagreeing with my thread closed statement , you are clearly "picking everybodys brains" on here , I saw this thread develop and thats why I left it alone . Leave the gas alone !!!!!!

What's the point of the forum if people can't come here and ask for advice!

The reason I disagreed with your post 33 is that it agreed with Chalked, who said in post 31 that I should use a GSR. I have already stated countless times that I will not touch the gas myself and will use a GSR!!!

I am trying to establish whether there is an alternative to running 20 feet of 22mm pipe on the outside of the house, across two doors, one window and through one gate. This was the only solution offered by the installer mentioned in post 13.

He was wrong. The solution is to find the 22-15 reducer, which I now know is on the inside of the house. I also know, thanks to the helpful people here (Shaun, Snowhead, GH77 & kop, etc), that I could stick with 15mm if the pressure drop does not exceed regs, or contradict the new boiler's pipe spec.

really !

Question you say that you have a glow worm Balanced Flue boiler, is this a standard boiler with hot water tank ? and is it being replaced (Upgraded to a combi) ? or are you just having a boiler swap ?

Yes, I've got a bog-standard Glow-worm Fuelsaver MkII with HW cylinder & immersion heater in airing cupboard and a small F&E tank in the loft. New boiler will be a straight swap - it won't be a combi (partly because the cylinder, pump, motorised valve & tankstat etc have already been changed for new ones).

If you are really going to hire a fully gas qualified engineer then you could ask him directly as he will surely give you then an update on your questions.

I have (Friday) and he did. He said the only way to find the existing 22mm pipe run is to lift the floorboards on the 1st floor. Chipboard t&g (nailed down of course, just to make life easy).

 

[kris]

Right wormwood your fine asking advice of course , anything we can help with is no problem but when asking about gas and pressures it does ring alarm bells as so many diyers out there , I know u worked or work on rigs and say u won't touch it but that doesn't prove anything as it's only words , everything your asking about should be spoken with your engineer , if you disagree with an engineers advice about upgrading pipe sizes then I can assure you that it's really common nowadays because of the gas consumption difference between older boilers and new condensers , as for members that are posting picks of test procedures , yes this thread should be closed me thinks , I agree with chalked and John,

 

[Wormwood]

Right wormwood..... if you disagree with an engineers advice about upgrading pipe sizes then I can assure you that it's really common nowadays because of the gas consumption difference between older boilers and new condensers ...

Right kris. I have not disagreed with an engineer's advice about pipe sizes. I have disagreed with first engineer's advice that the only option is to run the pipe on the outside of the house (post 37).

Fact: there are two options - inside and outside.

Inside is the advice given by the engineer on Friday and this is the route he will use. End of.

Btw, If I say I won't touch something - it means I won't touch something. Full stop.

[GH77]

The picture I posted doesn't tell you how to carry out a procedure, it does clarify that what the gsr said about pressures is correct, was used to reassure that the gsr does know what he's talking about ... the common theme on this thread is people continuously stating " use a gsr" and wormwood saying he will ... but yes now the thread should be closed before it all gets too heated

 

[Wormwood]

.... the common theme on this thread is people continuously stating " use a gsr" and wormwood saying he will...

Exactly, well said GH77.

 

[kris]

No need to get offensive mate , I've been quite polite to yourself, but saying you will or won't touch something doesn't give the go ahead to discuss matters which the forum rules clearly state not to, like I said wormwood were happy to advise but when u start getting into gas pressure testing or similar then it conversations you have with your engineer , I wish u good luck with your project ,

Right mate so post 11 doesn't explain anything, I never mentioned your name so don't presume I did thanks

 

[kris]

Please look at the top if this page FLASHING IN RED appearing on the page now and again, we won't give advise related to gas , now we will try give advice even when bridging onto the gas topic but when it starts to get past threshold barrier then we all play by the rules,

 

[GH77]

It states the pressures, doesn't state how to carry out the test ... that document is readily available to anyone with access to Google ... i'm now done with this thread ... i'm not getting anti or anything i like your input on other threads and respect you as an industry professional

 

[ShaunCorbs]

Right mate so post 11 doesn't explain anything, I never mentioned your name so don't presume I did thanks

Didn't you see the new rules kris we help these days instead of just having mods close threads

I would say if he was going to try and do something himself which I'm not condoning or suggesting and it's breaking the law and throws your home insurance out the window that no one could stop him and fyi all my info is in the manufacturers instructions so not hard to find

Education and understanding over just having a go I think is the way to go and it's been made clear all the way down the line your require a gas safe engy to do anything related to gas

Also a little question for you

Your working in someone's house and they ask you what your doing and a few questions would you answer them or say no only for a gas safe engy to know

Shaun out

 

[kris]

Wow I'm banging my head , deaf ears ,,,
I know we help Shaun but your twisting the hole thing , if I'm working in someone's house then they HAVE A GSR THERE, THEY ARENT GOING TO TRY THEMSELVES IF IM DOING IT, , Also
Shaun I know we don't close as many as croppie used to and it's more laxed but why o why does it flash across the top of the forum in RED , we don't give advice on Gas , if the rules changed that wouldn't flash , please scroll up to the top and wait till it appears,
Like I said I'll easy help even with gas until it passes the threshold , I'm out

I have asked admin for this thread to be closed.

Before it is closed would you give me your full names, dob and the pin number to your credit card?
Promise I wont use it.

I get where your coming from but your still giving info out and these days with everything on line it's not hard to find info, if anyone's going to mess with gas don't think a thread closure or banning will stop them

Gas safe won't do anything hs won't either non of the regulating bodies do, until you stop the sale of gas products to the public you won't do any dent

Last post on the matter don't see anything unsafe in my posts op was just asking

Guess we will just have to either disagree and move on

@Lou if you would like to clean any of my posts / delete them all together if they breach any of the forum rules go ahead

You again have disagreed and it will happen more often because it seems a little bit odd that you want to know things in detail. It's fine with us but it has to be asked outside of this forum when your gas safe installer comes. He will surely explain you all you need to know. It is a public forum and people on he will give you as much as advise which is needed anything regarding gas will be not answered as matter of safety. Do not take things wrong it's just a safety reason that's all it is.

We hope we still could help you.

Kind beards,

Ron

 

[GH77]

Same as Shaun, if i've broken any forum rules then I would like clarification from the administration ... unlike Shaun i'm new to the site, so I would like official clarification if i'm in the wrong .... if i am then i will hold my hands up and take it on the chin like a big boy ... i only want to help out

 

[kris]

Wow getting admin involved ,,it's getting petty like children, it makes the visit to the forum less enjoyable,

 

[kris]

Well said ron

 

[jtsplumbing]

Ok what about you get the new boiler fitted to the excising gas supply and if its within guide lines all well and good, but with the understanding that if not ! then there will be an extra charge to upgrade the supply pipe,
