Have a Moody 336 and number 62 and 63 on the job list are V - Berth and Gas Oven.

V Berth
The V Berth has a small rim around the edge. Any time the kids sit on it, it splips away. Any ideas on securing this down so that it is detachable and yet secure when placed on

Gas check.
Installing a new Nelson Spinflo. Any suggestions on doing the subsequent gas pressure check? Do I have to have it Corgi installed now or can I do it myself?

DIY is easy, but only if you are not chartering. With apologies to any gas fitters on this forum, CORGI fitters do not decide between their chosen job and rocket science.

To check the pressure, you need a manometer, here is one I found on Google.

For Butane you want 27 mbar, so the level difference in the U-tube should be about 27 cm. For Propane you want 37 mbar (37 cm). BTW, I've never noticed before that these figures seem to tally - as for some reason I've always used 11" and 15".
 
To add to Nigel's post you can check if you have a sound system simply by having a in line valve after the regulator and closing it, the level in your U tube has to remain the same for better than 3 or 4 mins if I remember correctly.
There can be a Small drop due to temp related drop that is the ambient temp needs about 5* to show anything significant tho.
 
Notice in particular that the second test, the one you will presumably be doing, is done at slightly below the normal regulated pressure. (20mb for butane 30mb for propane)

That ensures that there is no reserve of high pressure gas between the bottle and the regulator that will mask a small leak in the rest of the system.

It is small things like that which make the difference between a test done by an experienced professional armed with the knowledge to carry out the test properly and the enthusiastic DIYer who only thinks he knows what is involved.

Fortunately readers of this forum have the information available to do it properly thanks to Philip.
 
Thanks for that Vic. Saved as text, your explanation added, and filed in the Sahona how-to folder. I wonder if photographic evidence of the proceedings would substitute for a Corgi cert. in the event of questions being asked....
 
Surely you will only be connecting the cooker to the existing local isolation valve. You wont be touching the rest of the system

You will find some advice on Calormarine website on connections but for a job like that just check the connections you make (two at most i would have thought) with a leak detector spray or just some diluted washing up liquid. (wash that away after wards as it is allegedly corrosive )

However if you really must you should be able to find a Corgi from the "find an installer" on the Corgi website www.trustcorgi.com (enter "in your home" when asked)


Re the quarter berth
Can you make the "lips" much smaller?
Can you not fit them more securely?
Can you make then fit using dowels?
Impossible to advise without seeing the nature of the problem really.
 
I was told last week that it isn't just a Corgi fitter but a Corgi marine fitter you need and that up here on the sunny costa Clyde they are rarer than rocking horse poo.

[/ QUOTE ] What you need is one who is certified to work on LPG and prepared to work on boats. Its the certified to work on lpg thats important. If they arent certified and they work on lpg they get their arses kicked by Corgi.

Thats my understanding anyway but you get to specify both in "find an installer"

And one of the problems is that all the new additional certification for boat work (mainly as a result of the BW Boat Safety Scheme) has made maintaining registration uneconomic for many, so actually finig a 'qualified' person is now even more difiifcult.
 
I put in a Dumbarton postcode, because Rhumlady is in Dumbarton, specified the work to be on Boats/appliances and to be an LPG system and got plenty of results.

If subsequent enquiries reveal that none of these is either apropriately qualified or prepared to work on boats then I guess that is something that ought to be taken up with CORGI.
