Low/ No Gas pressure...please help

[diamondgas]

this should be common sense to any gas engineer. This engineer is either an idiot or not a gas engineer??

:iagree: first school basics you'd hope :iagree:

Good luck and let us know how it goes.

hi all

i can't thank you all enough for the info you have provided so far. Its a lil late now so i cant contact him to get any more info but will hopefully get onto it tomorrow to have him answer/ consider the points mentioned.

i'll sleep a bit better tonight knowing i've had second opinion from some great guys!!!

thanks again

we are here to help

honestly tho, if your engineer needs his customer to ask simple questions on the internet i would be worried about the work thats been done and everything aside consider a second engineer.

It'd be nice to know the outcome of your issue Sara should you be willing to return to the lions den Were ***** cats really Good night :waving:

cant see why he is getting zero my first thought was he was using the wrong test point on a zero govenor but he wouldnt get 21mb standing on that

Yes it is a bit peculiar. I am not saying the problem is air although air will compress to give a pressure reading, but it will not ignite. Seemingly the pipe is connected close to the meter and runs directly to the boiler wihtout any branches off. I assume its at least 22mm without to many bends or restricitions so it should work. Unless of course its blocked. I find more information would be needed to give a closer guess. The idea of continually firing the boiler up is about all a none gas person can do without breaking the gas train to check air has been purged. It doesn't however explain why the pressure drops to zero, although a fast acting gas valve can do that. Its hard to find out there are so many ifs and buts.

A U6 meter will supply about 64kW/hr ... Your guy if he's GSR will know all this.

64kW/hr? What sort of unit is that? Are you sure you're GSR?

Hi did you get the problem fixed ?

64kW/hr? What sort of unit is that? Are you sure you're GSR?

Yes is the short answer to your question but here's the long hand answer:

U6 meter - 6m[SUP]3[/SUP]/hr of gas

Here's the maths wheeto:

Heat input = (Gas Rate x Calorific Value of gas)/3.6

or

(6 x 38.6)/3.6 = 64.33 kW/hr

A U6/E6 meter will therefore supply appliances up to the value of 64kW max guaranteed! Any more than that required for the property and you'll require a larger gas meter!
