A surge suppression apparatus includes a housing, and a flexible diaphragm. The housing is divided into first and second sub-chambers by the diaphragm. The first sub-chamber is connected to a supply of liquid under pressure. The second sub-chamber contains a gas under pressure. The apparatus further comprises a gas reservoir in communication with the second sub-chamber so as, in use, to provide an effective volume which is substantially larger than that of the second sub-chamber.
