Abstract: An improved closure member is provided for sealing the open end of a pipe and which is particularly suited for a plastic pipe system. The closure member comprises a tubular cylindrical body closed at one end and which is insertable into the open end of a pipe. An O-ring around the closure member engages the inner periphery of the pipe and fluidly seals the closure member to the pipe while an enlarged diameter flange at the outer end of the closure member abuts against the open end of the pipe in order to prevent over insertion of the closure member into the pipe. At least one and preferably two axially extending channels are formed along the outer periphery of the closure member which are open to the outer end of the closure member through the enlarged diameter flange.

Abstract: A modular sump pump assembly is disclosed that consists of three components--a base module, a power module and a switch module. The base module includes the pump casing and is adapted to be connected to the piping that is utilized for discharging the liquid from the sump. The power module, which comprises the pump impeller, the motor, the connecting drive shaft and related parts can be inserted at the pump impeller end into and removed from the base module by means of a bayonet-type joint so that servicing of the power module can be performed merely by twisting the power module relative to the base module to disconnect the bayonet-type joint, after which the power module can be lifted from the sump. The switch module is connected to the power module so that it also can be serviced merely by removal of the power module from the base module and then, if desired, disconnected from the power module.
