ABSTRACT:
An improved sprinkler head (2) having a hollow housing (4) has a fluid inlet (5) for admitting water into housing (2). A drain valve (40) comprises an elongated flexible nipple (34) having an open upper end (35) and a closed lower end (36) having a normally closed drain passage (42). Nipple (34) is mounted in any drain port in housing (4). Whenever fluid pressures inside housing (4) increase above a first level, nipple (34) will have its walls bowed outwardly until the drain passage (42) is opened. Preferably, drain valve (40) is part of a check valve (30) which incorporates into it the structure of nipple (34).
