W+T Posted May 24, 2019 Author Report Share Posted May 24, 2019 Well that did/didnt work Fitted new cylinder reg and it was fine for a first bubble test but then it has done the same and just one bubble then nothing until you lift the tester button again and press then another bubble appears again then noting. So i am going to make a manometer asap. Oh and i am going to go and test it now again but leave it for 2 mins. Link to comment Share on other sites More sharing options...

So i am going to make a manometer asap. Oh and i am going to go and test it now again but leave it for 2 mins. This is the manometer test procedure that I was given (think it was from a forum member.) Our safety guy appears to do this: "The proper soundness test technique is as follows: A one minute let-by test at 10mb (4 inches) to test the isolation valve works (they sometimes don't, which can disguise a leak). You're looking for a RISE in pressure which will show the valve is faulty. This is followed by raising the system pressure to 30mb (12 inches) and waiting for the five minute stabilisation period. If during the stabilisation period the pressure changes, record the new pressure then the real five minute test period begins. After the five minute test period NO fall in pressure is acceptable. With a digital manometer 'no fall' means a fall of 0.3mb or less. A very aggressive and unforgiving test which dry compression fittings regularly fail, in my experience. A manometer is read by adding the difference between both sides of the watercolumn. In other words, if the water column moves down 1” on the pressure side and up 1” on the other side, that would equal 2” of water. The reading of amanometer that equals 2” of water column is .07226 PSI." Edited May 24, 2019 by Guest Link to comment Share on other sites More sharing options...
W+T Posted May 24, 2019 Author Report Share Posted May 24, 2019 Just been out and done 90 second test on all lines individually and all together and no bubbles at all. Maybe he first tie i did it tonight i didnt pressurise the system properly, who knows and i dont care as its fine now at long bloody last. BSS time Thanks all for the help as it was real bugging me that one. Just never thought a new reg would fail so quickly with hardy any use.

Captain Faffer surprisingly an objective and logical approach by an un-involved party can sometimes work wonders. glad it's all OK now. 1 Link to comment Share on other sites More sharing options...

Certainly it does. One thing that does make it difficult though is so many folk with different ideas and thoughts that can make it more difficult. Reason i stepped back a few days ago and put ideas i had been given in line and went from there. To may thoughts can make it worse for me to work out. Just would never of thought a new reg would fail so quick. But there you go, another lesson learned. Link to comment Share on other sites More sharing options...

W+T Posted May 30, 2019 Author Report Share Posted May 30, 2019 Keeping calm i am I tried the bubble tester again yesterday and again tonight and every time i do its different result of bubbles showing, sometimes non at all. I just popped back out and now there are non showing in each three lines individually or all together. I give up i think. BSS this Saturday and see what he thinks. If it fails i have found a local chap plumber that mite find time to come around but not for a week or two to have a look. Link to comment Share on other sites More sharing options...

I thought that before as for a day or so after i changed the reg it was ok but that was last week. now its back as last week random bubbles then non. .

You know that could be it kida, you may well be right. Got home tonoght and turbed the gas on and lef tit for 10 mins and nothing at all, no bubbles. Dont get why it takes so long for the pressure to build up though. Still its ok so thats all i need to now. BSS tomoz still. Link to comment Share on other sites More sharing options...

ditchcrawler Posted May 31, 2019 Report Share Posted May 31, 2019 I have never done pressure testing on such small systems. but one of the things we always did was to pressurise it and allow the temperature to stabilise before starting a test, What effect if any would charging these small pipes with propane via a regulator that drops the pressure from cylinder pressure, considering pressure reduction leads to refrigeration?

I think I posted this earlier, but something strange and similar goes on with our boat when the weather is cold. The bubble tester will show an odd bubble when it is minus something outside and about 30 degrees inside with the stove lit. Never a problem in more moderate temperatures. Yet a manometer test shows no problems even in extreme conditions, and copious amounts of leak detector spray shows nothing. I am coming to the conclusion that bubble testers can lead you up the garden path sometimes. I only test it in summer now Edited June 1, 2019 by Guest Link to comment Share on other sites More sharing options...

Nearly, i say that as it failed but only on the fire extinguishers and blanket. I knew what to buy and i had them in my basket. but i kept the wrong dam ones in. The ones i bought didnt have the BS Kite mark on. When i get them fitted i can send him pictures of them in situ to save a call out again and he will send me the Cert not bad for my first complete rebuild/refit. 1 Link to comment Share on other sites More sharing options...
