is there a need to put a gas cock before the bayonet on a free standing cooker? or does the self sealing bayonet act as isolation?

Discuss settle a dispute...... no isolation on free standing cooker in the Plumbing Jobs | The Job-board area at Plumbers Forums
there is no need to put a gas isolation valve before a bayonet fitting on a free standing cooker,the bayonet fitting does act as a perminted temp gas isolation ie for allowing removing of cooker for cleaning,works and replacement,howeve it is not aacceptable permanant gas isolation point(even if a gas isolation valve was fitted before it)
If cooker removed and bayonet fitting is not going to be used long term,the pipework should be capped off in the correct manor,with a cap end,would be good if there was a cap end that just pluged into the bayonet
imho
a properly fitted gas bayonet is acceptable as a permanent point of disconnection as long as it isnt leaking
No a Bayonet is not a acceptable permant point it needs to be capped, that would be ar if a bayonnet fitting is left uncapped had that question in my acs yesterday. Its just like a Lever valve that is no means of permeant isolation it has to be capped incase a little kid switches it on etc.
To be fair, the short term disconnection of a cooker is far less dangerous than a cooker connected to a supply when you think about it. What's more likely: a kid to press their finger into a bayonet long enough and hard enough to release a dangerous amount of gas or the same kid walking by a cooker, knocking the hob control tap with their teddy bear and spewing gas all round the kitchen while they walk off into the front room to build a lego train??
If you disconnect a cooker for a day or so. do a quick drop test to make sure things are ok to make sure the bayonet isn't passing, or even worse, get a 1/2" plug if it's what u need to sleep at night!
Obviously for long term, cap the thing off...
Depends on the job.
Well as i got taught very recently like i said yesterday, a bayonnet is not aloud to be left by a gas engineer for a means of isolaation, a customer can full willing leave a gas bayonet fitting disconected for a long period of time but when that enginner comes round and servies or what ever to that gas pipe it should be capped. As my tutor said kids stick fingers where they dont belong. I had a question on it in my paws book and answered with no it cannot be left as a isolation point, and should be capped, and it dint come back as wrong
Also in my parctical on gas pipe work core, one of my faults i had to pick up was a bayonet fitting was left uncapped, and the examiner said it needed to be secured......
Also im not here to argue about it, i was just expressing what i have been taught, and that i dont think it is acceptable.
why do you mention argue? someone asked a question, someone else answered it, i commented that they are wrong, you commented i am wrong because you have been taught differently, so we are not argueing about it merely discussing a different point of view and i would respectfully suggest you check with either your training provider and or GSR for clarification, but be sure to clarify exactly what you ask (especially GSR) as they are great at body swerving questions, but if you ask a specific accurate question you will get an answer, so the statement i would make is " a properly fitted and confirmed as gas tight bayonet can be left as a permanent point of termination for a gas pipe" a discussion for another day could be "is it best practice to leave a bayonet" and some would discuss either yes or no as that is subjective, but in the first instance let us confirm whether it is an offence to leave one, which in my opinion would make ir RIDDOR reportable if you liken it to leaving an uncapped lever gas valve
hoas kirkgas says if an electric cooker or something was going in instead you,d cap it permently
what about blocking the gas supply with them little dust disk (bg use them and transco ) are they fit for purpose KIRKGAS?
I have them blank discs, use them when im soldering gas pipes when i remove meter. They are designed for temporary use though wouldn't think they would be acceptable as a permanent way of capping off gas.
