Abstract: According to one aspect, a dilation device may include a body, at least one loop actuator attached to the body, and a sheath attached to the body at a proximal end and attached to the loop actuator at a distal end.

Abstract: A dilation system (10) comprising a speculum (20) with a body and at least one jaw (24,26) pivotally attached to the body; and a sheath (30) that is attached on the body around the at least one jaw, and expandable from a constricted position to an expanded position. A dilation comprising: at least one proximal ring (133P) spaced apart from at least one distal ring (133D); a plurality of longitudinal ribs (32) spanning between each of the proximal and distal rings; and a web (34) spanning between at least each of the plurality of ribs, wherein the sheath is expandable from a constricted position to an expanded position. Related methods are also disclosed.

Abstract: A removable, convenient main drain testing system is provided through the use of a testing device that includes a cap clampable about a drain pipe, an air pressure gauge, a valve and connection to an air compressor. The assembly can be moved from one jobsite to the other with ease and can be transported in a plumber's tool kit without cumbersome apparatus. The test involves injecting compressed air into the system with the valve open, followed by closing of the valve when a test pressure has been obtained and observing the pressure gauge to look for pressure drops indicating leaks. The valve also is useful for the introduction into higher pressure air to ascertain where leaks are occurring should any be observed.
