What a job!! baffled!

[dylski]

Alrite lads, ive only been GSR about 6 months now but ive worked for 3 years on gas with previous employers and NEVER seen or heard of this...story goes...im called out to rectify a gas leak as transco or someone capped it due to a leak they state was coming from the baonet fixing on a hob! i tell the customer solid pipe is required and begin the job, awkward but im done in a hour or so and theres still a pressure drop, i find out the gas was fitted by some unregisterd people and ther seems to be leaks every where..after redoing the hob 4-5 times (being un-confident due to just satrting out on my own) and rectifying many over leaks its still dropping..so i run new piping from the meter to the boiler and cap it in the kitchen to check my work, all sound...i connect to hob and my manometer reads no oressure!! i check all joints with detection fluid, all sound..then itake outmy fga which has a gas sensor, after still getting a skight detection of gas undee the hob im baffked and decide to check tje burntrs as the drop test suggests an open end..turns out 3/5 of the burners were releasing gas on there own!!

Has anyone had this before and no the reason??? ive reokaced the hob now as it was still under warranty but id like to know fir the future, cheers lads (sorry its so long)!

Sounds like cheep make hob, had let by on older hobs due to worn gas taps. Get them to replace hob under warranty but disconnect and cap ID leave warning notice.

Did you leak test the existing before you started?

If you did, did you fix the existing leaks before you started any alteration?, apparrently not.

What about isolation valve for hob?
isolate the hob and cap if still leaking otherwise then if i'm reading it right you left a gas leak !!!!!

it sounds like your lack of experience ment you worked slightly in the wrong order. Never trust what has been written down on a warning notice, you really need to be checking whats wrong before jumping into pipework etc......

If you had tested the full installation and maybe broken it down to identify the problems you would have saved alot of time and effort. For example if you had tested the installation and got a drop, isolated the hob and still got a drop then you would have known straight away there are other issues that need resolving. Or if you identifed the hob leaked past its iso valve you could have used leak dec or sniffa and found the hob was faulty without all the trouble of altering pipework.

i hope im making sense. Do you have any experienced engineers you know you can call upon to help you out when you get stuck?? sometimes we all need help with jobs and i would not be ashamed to ask for help while you are finding your feet in the trade.

I agree 100%, always conduct your own tests before starting any work.

 

[GQuigley67]

should always test before you begin work, when i tested the gas today we recorded a 6mb drop so we renewed the full gas supply, if we didnt test it at the start we would have wasted time trying to find the leak as it would have to be rectified before we left the house costing us time

If im honest i just beleived what it sid on the id form, seen the baonet and i knew it needed changing anyway..mistake i know and its a lesson learnt believe me. And just for the record i would NEVER leave a gas leak, im sorry if i confused you some were. also i am confident in my work but its only been a few months were i havnt been had someone on site just to double check my thoughts, the fact that i didnt even think of the hob letting by made me question my work. Im glad it happened though because ill never forget it now!

when tracing a gas leak start by isolating appliances mate! rather than checking all the pipework

do the test, if it fails, close the boiler gas inlet, if it fails close or cap the pipe to cooker/hob if you done this first
this would have saved you in renewing all that pipework / making urself look confused infront of customer.

 

[dylski]

your making perfect sense awheating, thanks for the posotive feed back, its what us newbies need! ive learnt a very valuble lesson, and ill never make that mistake again believe me! cheers mate

its also nice to know that even the most experienced need a second opinion sometimes..thats give me abit of confidence!

 

[mcniven]

ofcourse dyl! you may of specialised in an area, for example servicing of old bbu that not a lot of young engineers have a great deal experience in (myself) where as installations and fault finding youv not touched upon! its all one big learning wave we surf for the rest of our lifes. (unless u become a gaffer)

this is a OPEN THREAD

were all learning on here or we wouldnt be here dylski so good for you for asking and even better that you can analyse your own work and see room for improvement i met a lead engineer and a new service engineer for ldeal commercial today they didnt need anyones help it was painful for me to watch perhaps the lead engineer though he shouldnt look out of his depth but believe me when you,re stuck its better to ask for help rather than digging a deeper hole i wont hesitate to ask you for help
