Hi everyone, just gone to change my 40 40 membrane and when I slide the new one into the stainless housing I was surprised it's not a tight fit at all? I would say there's about a 1mm gap all the way around the large rubber seal on the membrane. Surely that can't be right?
I tried the old one back in and it's a bit better but still not tight at all. Both membranes are good ones so I'm guessing the housing is no good?
I got it from another window cleaner when I first started so could have been a cheap one.
Any help appreciated
