About a year ago I replaceed the drum bearings on my Hoover quatro system 1300 ws136 washer/dryer. When I had the drum out I detatched 2 rubber push fit hoses that were held in place with some type of sealant. when re-attaching these hoses to the plastic outer drum I applied a little silicone sealant thinking it would be ok. A couple of days ago I noticed a small leak and on closer inspection both of the hoses were leaking slightly, the silicone doesn't seam to be bonding to the plastic. Which sealant should I use !!
