I recently bought a gas cylinder from a well known DIY chain. The cylinder was then located in the room I worked in every day and I started smelling an awful smell in the room and thought maybe I'd a waste pipe issue. Eventually realised after a week or two that it was gas I was smelling. The cylinder was leaking. I took it outside and the smell improved. Upon inspection, there was a return label on the cylinder saying it had already been returned as leaking by another customer, but despite this, I was given the cylinder upon purchase, brought it home and had it located in a room where candles were regularly lit. I've contacted the store who have said I must give them back the cylinder as it's the property of calor, so it can be inspected, but not a word from them about how this could have had a major repercussion in my home. I had taken some time off work due to some respiratory issues and I'm wondering now if it was from breathing the gas. That aside, it was a real breach of their health and safety protocols. Any suggestions on whether I should pursue this with the retailer?
