A liquid level sight gage has an elongated chamber block with a liquid chamber, a lens covering the liquid chamber, and a cover with an elongated viewing slot secured to the block with the lens interposed therebetween. Side beams of the cover, through which bolts securing the cover to the chamber block extend, have ovate configurations, providing greater mass at their centers, thereby providing greater support towards the centers of the chamber block sidewalls where the tendency to bulge is greatest. The bolts extend through longitudinally spaced holes in the side beams in contact with the chamber sidewalls and are transversely supported by the side beams.

Liquid sight gage cover

An auxiliary jet sump pump, particularly for use with a main conventional electrical sump pump or the like, as a substitute pump in the event the main pump is inoperative, or as a supplemental pump in the event the capacity of the main pump is exceeded. The auxiliary pump is adapted to be mounted in the sump, and discharges into the discharge pipe of the main pump. The auxiliary pump is powered by water under pressure, for example water from the usual municipal water supply. A float-actuated valve is provided which admits water into the auxiliary pump when the water level in the sump rises to a first predetermined level above normal, and which shuts off the water when the water level reaches a second predetermined level lower than the first predetermined level.
