undersized gas pipe shock!

[Agile]

At least you measured the run

It's not all bad news

But he does not seem to know that he has to count the number of elbows as well!

That all you can do, son? try harder,you`re not in my league,


Thankfully not!

Ok, in answer to your question (and I'm an installer primarily), from experience you know the size required, However for a long run (I call upto 20m long) I would always take 5 mins to do the calculations.

No, you wouldn`t, because if it was a boiler change, you would probably just swap the boiler, lucky if you you checked the working pressure mate, the point that all these armchair heroes are missing because they haven`t installed f*uck all in their lives, is the fact that i am talking about replacing a gas appliance on an existing installation, so the only reason i knew that the carcass was undesized was because i checked the working pressure at the boiler and it told me that, i asked simply if anyone pipe sized when fitting a boiler, i should have asked if anyone took in to consideration the existing pipe sizes when fitting a replacement boiler, i didn`t stand a chance though did i, all the clowns piled in and totally missed the point and didn`t read in to the question i was asking,too busy to make me prove i was worthy of asking their noble advice, t*ossers.

It`s an existing gas carcass you halfwit!! climb down of your pedestal and read my original post!

True

he's probably got a sore knee bending all that 22mm copper for the scrappy

Re read your own post you half wit its not an existing carcass

you said piped it in 22 from meter as you do.


Keep up with your own lies at least

Hopefully, all you idiots banging on about pressure drops over pipes etc, have finally realised my question was: does anyone when fitting a replacement boiler, bother to check/calculate EXISTING pipe sizes or like me, do you find out after you have installed the appliance that the carcass is too small? Because i don`t price for that error, i must admit and it`s costly. That was going to be my next point. Thank you and goodnight to all.

You are quite right actually, i failed to mention it was an existing gas carcass, but seeing as you persist, with an appliance on, what does checking the working pressure at the meter do? regardless of the gas carcass? you have 5 minutes to look it up.....

NO NEVER...

You have been caught out with your lack of experience, or laziness.

oh FFS i will humour you so you can use it in future .
You said you where getting 18mb at appliance which was being asked for , well if you where getting 19mb at meter then 18mb at appliance is totally acceptable and meets the regs regardless of pipe size or length of run .

Oh and what 33 kw combi was it

By you?

I`m shakin in me boots to be honoured by someone who has 4 posts to his name, all of them on every other gas engineer`s coat tails, do one , no mark.

Wow, what a revelation!! so what! I know the incoming pressure at the gas meter will affect working pressure at boiler, i simply allow for that in calcs, i didn`t have to the working pressure at the meter was approx 20mbar and 16.5 at boiler, so????? undersized carcass?????

If I was a customer, it would greatly worry me to read that there are RGIs who never calculate the gas pipe size are you have been trained to do.

Suppose you heard surgeons chatting that they never bothered to check to see if the patient was still breathing when they finished the operation? Would that encourage you to go for a brain transplant?

However, this site covers RGI discussions by having a section called the Combustion Chamber which is only accessible and viewable by RGIs.

FFS Changing what you put with every post quick go back and edit everything.

No point me arguing with an idiot you will just drag me down to your level and beat me with experience.

You are best staying there then to be fair, out of interest, in the past year, how many boilers/unvented/vented systems have you installed? if you don`t mind answering?
