Gas plumbing question?

[Steve_D]

I'm fitting a kitchen for my son. Took out the gas hob which is only a year old so will be re-used and in the same position. It has a rubber connection pipe with bayonet fitting.

A guy who came in to do some plastering said you can't use rubber pipe any more and it has to be hard plumbed in which will be a bit of a bar steward now I've fitted all the new kitchen units.

Is this correct? And if so then why can you still buy the hoses from Screwfix etc.?

Many thanks
Steve

PS despite it only being a year old I did intend to replace the rubber pipe anyway.

dunno but i imagine if you are doing anything other than a straight in out then it would MOST LIKELY need a registered plumber to do it http://www.gassaferegister.co.uk/

Even them I think you still need a Gassafe guy.

It worked for me.

If you're going to 'break the law' by fitting it yourself, then you may as well 'break the law' by using a bayonet rubber hose. They were obviously deemed safe enough a few years ago.

I suppose you have to bear in mind that if your house blows up, the insurers may decline to pay for it...

YES

So having fitted the hob in the worktop someone has to climb in where the cooker will be and solder up some pipes.
So how do you then pipe the cooker?

Gas hobs have always had to be hard plumbed.
Gas hoses are for freestanding cookers.
Bear in mind that although you can legally plug and un-plug the bayonet fitting, you should test the connection between the cooker and hose for gas tightness and (I believe) that's a Gas Safe issue.

Gas safe registered plumbers are trained the dark and ancient ways from the Grand masters.

Alternatively we plumb the hob in first, and then use the cooker hose on the oven so we can then slide the oven in.

The instruction label on the underside of the hob says it should be connected with a flexible pipe. Will have a look and find the exact wording.

You can not connect a Hob with a flexible connection. No two ways about it. It must be piped rigid with an isolation valve.

The cooker can be connected with a flexible hose with a downwards facing bayonet connector.

I appreciate you're just quoting regs, but I'm struggling to understand the logic. If a flexible hose is deemed 'too dangerous' to use for a hob, why is it 'safe' for a cooker? Or is one flexible hose deemed an acceptable risk but two hoses is not?

It probably is perfectly safe. The reason you are allowed bayonets and hoses on cookers is for ease of removal.
A hob is a permanent fixture a cooker is not.

Maybe because a cooker is basically mobile, free standing, and WILL move occasionally, thus possibly cracking a hard pipe, whereas a hob will generally not move at all? Just a guess.

OK, interesting point - and of course it would be physically impossible to 'hard-plumb' a cooker. However, I'd suggest that when one changes a cooker, one probably changes the hob as well, and both are fixed in position, the cooker with screws at the front.

Still, I'm all electric now
