41 forum posts	and without appearing to be too critical the sliding faces of both the slide valve and the valve chest need to be flat and smooth to get the seal you need. In the 1st and 2nd picture it looks as if the valve chest seat need some attention - it doesn't look very smooth in the photograph. Also ensure when the slide valve is in the correct position as suggested by Martin, that the steel slide valve rod isn't stopping the slide valve from making contact with the valve chest surface. This could happen if the steel rod and the gland it runs through are not aligned correctly. Barry Edited By Barry Q on 02/12/2015 10:12:38
