Big Al Posted March 24, 2013 Report Share Posted March 24, 2013 Can anyone tell me if it is possible to safely remove the valve on the pressured bottle. Or is it a big no no? Id love to make a wood burning workshop heater out of it. Quote Link to comment Share on other sites More sharing options...
kennett Posted March 24, 2013 Report Share Posted March 24, 2013 Helped a mate do this, we made sure the bottle was empty and then drilled a hole to be sure. Just make sure you don't use heat to make the first cut, so angle grinder and not oxy-acetylene Quote Link to comment Share on other sites More sharing options...
alexl Posted March 24, 2013 Report Share Posted March 24, 2013 Filling the bottle to the brim with water should displace all gas inside. Quote Link to comment Share on other sites More sharing options...

FalconFN Posted March 24, 2013 Report Share Posted March 24, 2013 I think the bottles are only leased so they remain the property of the LPG supplier even when empty, saying that I have done this and if you really want to do it all you need to do is open the valve and leave over night - there will still be gas inside even after leaving it open so don't cut the bottle! Unscrew the valve (very difficult as there isn't much room for a spanner) and then fill to the brim with water and pour out. Make sure you do all of this outside and remember that it is very dangerous and probably not a wise thing to do. Quote Link to comment Share on other sites More sharing options...

Can you slowly unscrew the fitting at the top of the bottle? Quote Link to comment Share on other sites More sharing options...

Thanks for the replies but Im starting to think it would be alot safer to put on another fleece. Edited March 24, 2013 by Big Al Quote Link to comment Share on other sites More sharing options...

Big Al Posted March 24, 2013 Author Report Share Posted March 24, 2013 The gas bottle I have has no screw valve. It is pne of the old ones when the regulator did all the work. The only way I can empty it is to put on a regulator but I threw that away with the old Super Ser heater the bottle was in. I may have to wait for a different bottle thats not as old.

webber Posted March 24, 2013 Report Share Posted March 24, 2013 The gas cylinder is the property of the gas company whos name is on the cylinder. Despite the advise above, removing the valve on an LPG cylinder is a risky business no matter how careful you are. Thanks to an idiot not following instructions I was almost killed 5 years ago, I'm still recovering. You'll probably get away with nicking the cylinder, you may not get away with removing the vale. Do a PW search for Whiston and have a read. webber Quote Link to comment Share on other sites More sharing options...
Big Al Posted March 24, 2013 Author Report Share Posted March 24, 2013 Webber I have just finished reading the thread. Thats it decided then No way. I have a wife and three kids.

hodge911 Posted March 30, 2013 Report Share Posted March 30, 2013 made quite a few now red bottles easiest. open valve fully and let stand for 2 weeks then remove valve from bottle some have come out some have had to be broken off fill brimming full with water and leave for a further 2 weeks then drill hole in bottom allow to drain then cut as required. using angle grinder and a 1mm thick metal cutting disc .

marc147 Posted March 31, 2013 Report Share Posted March 31, 2013 What ever you do be careful. They are like unexploded bombs. My uncle was killed at the age of 32 opening one, it was his job to do so. He worked for a scrap yard and it was ment to be empty. First thing I new my cousin and I (Same age and school) were pulled out of class and told my mum was coming to get us. Please make sure it is empty.

Big Al Posted March 31, 2013 Author Report Share Posted March 31, 2013 I'm not touching it. Webber's experience convinced me it is a bad idea. It is off the council recycling site this morning. Quote Link to comment Share on other sites More sharing options...
Shooting2 Posted March 31, 2013 Report Share Posted March 31, 2013 (edited) Use a ballon gas bottle from pubs, most pubs throw them out when empty. Im not on about the long talk ones but the balloon gas they are shaped like a 13kg propane/butane bottle. They are allot safer but the metal isn't as thick Edited March 31, 2013 by Shooting2 Quote Link to comment Share on other sites More sharing options...
Twistedsanity Posted March 31, 2013 Report Share Posted March 31, 2013 Remember that unlike natural gas LPG is heavier than air and any dispelled gas will sink to the floor and stay there until the wind disperses it so don't do this in your shed , outside on a flat surface to allow the gas to disperse is best , I would open the valve and let any pressurised gas out then hang the bottle upside down and let gravity remove the contents , the filling with water idea is a good one but drilling a hole into a bottle to see if its empty is a bit suicidal! I have qualifications is LPG Quote Link to comment Share on other sites More sharing options...
DreadedFlapper Posted March 31, 2013 Report Share Posted March 31, 2013 I've done a few but before I go at it with the grinder I twist the valve off using a carver clamp and a long piece of tube. Then fill with water and leave for a day or two. But webbers incident certainly makes ya think! Is it really worth it? Quote Link to comment Share on other sites More sharing options...
Big Al Posted March 31, 2013 Author Report Share Posted March 31, 2013 Thanks for all the replies but I'm not risking it. I'm not that desperate - hopefully the weather will warm up a bit soon! Quote Link to comment Share on other sites More sharing options...
