Just installed an Ideal Create Edge BTW pan - have connected to the waste with a new female connector onto the male waste protrusion on the pan - the protrusion is not as long as I've seen before, but it seemed OK for the connector - but when I turned the water on and flushed the first time, the connection seeps - have tried pushing the connector on as far as i can, but seep persists - anything I can do to stop this???
