Freekin jeezez .......you are only having a cooker installed..WTFff goes on...Is this a wind up?..Mr Wobbe number!

no, that was the past story, gas pipes re-laid and boiler installed and some water feeds and radiator feeds.

The matter of present times is a cooker being installed. At last. I hope.

Is this at the gas meter?

from gas metre, 20 m effective length in 28mm pipe to come to a Tee: one end of the Tee 4m effective length in 22 mmpipe run to end up in a 25kW boiler.
The other end of the Tee is probably 3 or 4m of effective length in 15mm copper pipe
Then it would be connected to cooker with 1/2 inch hose which SF claims it has 9.5mm bore size; length of hose is 1m

On SF they sell the standard hose with bayonet fitting (as recommended by manufacturer), which has a bore size of 9.5mm.

Then it would be connected to cooker with 1/2 inch hose which SF claims it has 8.5mm bore size; length of hose is 1m

What''s more amusing:

I am looking now at the SF website on my computer. I was able to find easily part nr 33878. Bayonet connection, internal bore diameter 12.5mm. Essentially equal to a 15mm copper pipe.
Smartphones are the work of the devil, I keep repeating that.

What a palaver I made!
