Hi. I thought I'd do my bit and return a little of the help I have received on this brilliant forum. I recently sent this tweet to Drayton @DraytonHeating Hi. I think this is one of your push fit elbows. Can it be demounted (the push fit) If so, how. Can it be remounted or are they one time use only. Ta. Any videos on their installation. Their reply is in the photo Basically, they said they are one time use only Hope this proves helpful to other hapless DIYers like me. Haha Thanks again to everyone over the last few days.
