    Exactly, well said GH77.

    Gas pressure question

    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...

    Gas pressure question

    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).

    Gas pressure question

    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...

    Gas pressure question

    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...

    Gas pressure question

    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...

    Gas pressure question

    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.

    Gas pressure question

    Ok, thanks Shaun - I understand. What do you think of my plan in post 17? Thanks for that explanation GH77. The pipe coming out of the meter is 22mm, so it reduces to 15mm somewhere inside the house. It would be really good if I could find out exactly where - maybe it's right next to the...

    Gas pressure question

    I still don't see why the pipe has to be 22mm as long as the pressure drop is within regs (as per Shaun and Snowhead's advice).

    Gas pressure question

    See post 16 paragraph 3 :) I've worked on a gas rig in the North Sea so I'm not tempted to do anything myself gas-wise.

    Gas pressure question

    Why will I end up with 22mm? Yes, there is earth bonding on gas & water pipes and it's ok (it was checked & certified by an electrician in June).

    Gas pressure question

    My current plan is this. 1. Ask the supplier to change the whole meter for a new one. 2. Get someone in to measure the gas pressure in and out of the meter. Then measure the working pressure at the boiler. Sounds reasonable to me. :):):)

    Gas pressure question

    Part of the pavement/road was dug up last year - I didn't pay any attention to it though, so I'm not sure if it was gas, H2O or electricity. As far as I know, no other house in the road has had to resort to swapping to a 22mm pipe when they've had a new boiler fitted - hence my suspicion of...

    Gas pressure question

    How do I find out the figure for the bits I've highlighted red Shaun? I should mention that the chap who measured the pressure at the boiler did it twice on two different days - and he got two completely different readings. This was using the same digital measurement device. Why would that...

    Gas pressure question

    No, but if the pressure is high enough for my existing boiler (Glow-Worm), I don't see why it's not high enough for a new boiler (any ordinary/standard replacement). The Glow-Worm has only ever cut out twice in the 10 years I've owned the house and that was in extremely high winds - the wind...

    Gas pressure question

    By 'appliance working', do you mean the measuring device (e.g. this one) is connected to the boiler itself, while the boiler is running?

    Gas pressure question

    No, they said it was too low regardless of the boiler's kw. They reckoned a 22mm pipe would give more mbars.

    Gas pressure question

    What could be wrong with the pipework? The existing boiler has run perfectly happily with it for 30 years. :confused: I don't know what the new boiler will be.

    Gas pressure question

    Thanks for the reply Shaun. I think they were 19mbar before the regulator change and 23 after it.
