Gas leak

trg

Hi,

We have recently completed a new-build house. A couple of weeks after moving in we noticed a gas leak, smell was brutal :eek: The only gas we have is to the cooker, a rangemaster 900.

We got the plumber back and he did a test on the gas fittings outside and inside and found no leak. We complained to the shop where we bought the cooker, who sent an engineer out who tested it and said the cooker was perfect, i then got the plumber back out, he just retested everything, took them apart and put them back together again (for the sake of doing something it seemed like) and the leak continues.

Not very convenient going in and out turning on and off gas all the time and i have no idea what to do next.

Any suggestions?

Thanks

Type of gas, LPG bottled or natural gas (meter)?

Well from the plumbers side of things he should be able to do a test while your there to witness it using the u guage . if this test doesnt show a leak in the tested pipework then your leak has to be in cooker or whatever , can you get a can of leak detection spray and spray the fittings while its in use .

Its LPG gas anyway, dont really know why he tested outside since the smell is in the kitchen. He ran a test on it, not sure of the name of it but he was waiting for this bubble to drop anyway when the leak would occur but it never came, this was outside, inside he covered all the pipe and fittings with sudsy water, not leak detection spray!

Am at a crossroads since neither potentially culpable party is fixing it or admitting blame i.e. i doubt they will be offering me a new cooker!

If the plumber didn't find anything with Gas .. it might be your waste?

Only reason I'm saying this, was working in a building and we called out the gas guys, they couldnt find anything .. afterwards, we found it was an unused toilet .. the toilet had dried up so there was nothing in the U-Bend stopping the smell from the sewage pipes coming back up..

Balmark, am certain it isnt anything to do with waste, when Gas is on the smell comes, when Gas is turned off the smell leaves, simple as that

The plumber would have done a pressure test from outside, which will tell you if you have a leak or not, but not where it is. you can diagnose by checking are you getting the smell once you have the gas turned on (probably pipework leaking), or when the cooker is in use? (cooker leaking). Every gas engineer should have a gas analyzer, most of which have a sniffer setting which could pinpoint the problem.

I've the exact same problem as the OP. Plumber cannot find a leak at all. Thought it might have been the regulator on the cylinder that was causing the problem, but he put a new one on and still there's a smell of gas. He had this little machine that went crazy when it detected gas. Everywhere he checked was fine, until he went near the valves, and it went mental.

Then its likely that there is a leak at the valves. Which valves specifically?

It looks to be all 4 of them, but only when the gas detector is right on the valves. Is it a big job to replace them, do you know? The guy in Waterford Stanley told me that the freezing temperatures had damaged the regulator on the cylinder outside, letting in too much gas. My plumber thought the same. Is it safe to just turn the gas on and off as needed over christmas, as we've no other way of boiling spuds and veg, and are having family over here on St. Stephen's Day.

I'd stay well clear of the cooker until it's fixed ,buy a camping stove to boil your stuff or even plug an electric hob etc.

Lpg is like water ,it sits on the ground around your feet and all it needs is a spark.

Would you not even use the electric oven part? Just tried ringing my plumber. He's pissed off the England for Christmas.

your plumber needs to isolate the cooker, test the pipe work to 100m/bar. if there is no leak i would then put a 20m/bar test on the cooker, this will only test as far as the gas valves, you would need to use soap water after the valves or a gas sniffer. lpg can be letal. rgi dont cover lpg. but get a propper gas guy how knows what he doing.

Test is 150mbar then 28 or 37mbar, apart from me being nerdy the bit about getting a proper gas guy in is spot on, if you had done you OP would know what the issue is with your leak as there is a process of a elimination, if the valves have been identified by your plumber then you have your answer but you should ask what the working pressure is to see if any damage has been done with over pressurizing if the regulator is duff, also DON'T USE IT:)
