I can't get that big rubber washer to stay inside the 'housing' so that I can screw the filter back on. I've tried pushing it in but it just doesn't stay there. I've been trying for ages now, it's driving me crazy! Is there some trick I'm missing or do I just have to shove it in harder?
Tempted to swap the whole thing for a spin on one.
