malcolmbebb Posted October 4, 2010 Share Posted October 4, 2010 Hi, The air valve on my Rochelle sounds like it's suffering from terminal asthma. It is quite hard to pull, not so hard to push, and makes a very audible whistle on pull. I've had a look and all looks to be in order. The pad lifts a fair way, the hole seems a good size and there are no obstructions. The hole is drilled pretty square, with quite sharp edges, and I'm wondering if the air rushing over the edges is causing the whistle. I'm wondering whether to round the edges of the hole slightly - does this seem a good idea? TIA Malcolm of course, plucking up the courage to dismantle it further is another story...
