A peristaltic pumphead is provided that has a pumping chamber within which is disposed a pressing element for exerting a peristaltic action on a tube extending within the pumping chamber, and an auxiliary chamber which in normal use is a dry chamber. The pumping chamber and the auxiliary chamber are arranged in fluid communication such that liquid which escapes from the tube into the pumping chamber flows from the pumping chamber into the auxiliary chamber.
