Sump pump alarm
First Claim
1. An electric sump pump having a liquid level alarm switch attached thereto, a power cord having one end connected with said sump pump and an opposite end attached to a plug remote from said pump, an alarm that is activated by said alarm switch, and a common enclosure for said plug and said alarm, whereby insertion of said plug into a socket locates said alarm and said enclosure in a desirable remote position relative to said pump.

Abstract
A sump pump has a float operated alarm switch mounted on the top end of the pump housing for activating an alarm when water rises above a normal operating level. The alarm is in a remote enclosure with the pump power plug so that plugging in the unit automatically positions the alarm in a desirable location to be heard. The power cord and alarm switch wire extend through a flexible corrugated tube that is attached to the pump housing and the alarm enclosure by strain relief connections that do not compressively crush the tube.

- 1. An electric sump pump having a liquid level alarm switch attached thereto, a power cord having one end connected with said sump pump and an opposite end attached to a plug remote from said pump, an alarm that is activated by said alarm switch, and a common enclosure for said plug and said alarm, whereby insertion of said plug into a socket locates said alarm and said enclosure in a desirable remote position relative to said pump.
- 10. A sump pump having a housing, said housing having a housing top end, a power cord opening in said top end, a switch support secured to said top end and projecting outwardly therefrom, said switch support having a support sleeve extending upwardly therefrom in alignment with said power cord opening, said support sleeve having longitudinally-spaced circumferential external ribs thereon, a flexible corrugated tube having alternating circumferential external and internal grooves and ridges along the length thereof, said corrugated tube having a tube end portion received over said support sleeve with said external ribs on said support sleeve received in said tube internal grooves, a cover member positioned over said support, said cover member having cooperating opposed parts with a cover opening therebetween receiving said tube end portion, and said cover opening having longitudinally-spaced inwardly extending circumferential ribs received in said tube external grooves.
- 16. An electric sump pump having a liquid level sensing alarm switch mounted thereon, an alarm remote from said pump and said alarm switch, said alarm being electrically connected with said alarm switch, said alarm switch being operable to activate said alarm in response to a predetermined liquid level externally of said pump, said pump including a pump housing having a pump housing top end, a switch support extending outwardly from said pump housing top end, and said alarm switch being mounted on said switch support externally of said housing.
- 19. An electric sump pump having a liquid level sensing alarm switch mounted thereon, an alarm remote from said pump and said alarm switch, said alarm being electrically connected with said alarm switch, said alarm switch being operable to activate said alarm in response to a predetermined liquid level externally of said pump, said pump including an electric motor, a motor power cord attached to said pump and having a power plug remote from said pump, an alarm enclosure in which said alarm is mounted, and said power plug being attached to said alarm enclosure.
-
21. An electric sump pump having a liquid level sensing alarm switch mounted thereon, an alarm remote from said pump and said alarm switch, said alarm being electrically connected with said alarm switch, said alarm switch being operable to activate said alarm in response to a predetermined liquid level externally of said pump, said pump including an electric motor, a motor power cord attached to said pump and having a power plug remote from said pump, an alarm enclosure in which said alarm is mounted, said power plug being attached to said alarm enclosure, said plug being selectively rotatable relative to said enclosure, and cooperating interdigitating lugs and recesses between said plug and said enclosure to selectively lock said plug against rotation relative to said housing.
- 22. An electric sump pump having a liquid level sensing alarm switch mounted thereon, an alarm remote from said pump and said alarm switch, said alarm being electrically connected with said alarm switch, said alarm switch being operable to activate said alarm in response to a predetermined liquid level externally of said pump, said pump including an electric motor, a motor power cord attached to said pump and having a power plug remote from said pump, an alarm enclosure in which said alarm is mounted, said power plug being attached to said alarm enclosure, a flexible corrugated tube enclosing said motor power cord, said corrugated tube having alternating circumferential grooves and ridges along the length thereof, said enclosure having front and rear parts with a tube opening therebetween through which said tube extends into said enclosure, and opposed ribs on said front and rear enclosure parts received in at last one of said tube circumferential grooves to prevent relative longitudinal movement between said corrugated tube and said enclosure.
- 26. An electric sump pump having a liquid level sensing alarm switch mounted thereon, an alarm remote from said pump and said alarm switch, said alarm being electrically connected with said alarm switch, said alarm switch being operable to activate said alarm in response to a predetermined liquid level externally of said pump, said pump including a pump housing having a top end, a power cord opening in said top end, a switch support secured to said top end and projecting outwardly therefrom, said alarm switch being attached to said switch support, said switch support having a support sleeve extending upwardly therefrom in alignment with said power cord opening, said support sleeve having longitudinally-spaced circumferential external ribs thereon, a flexible corrugated tube having alternating circumferential external and internal grooves and ridges along the length thereof, said corrugated tube having a tube end portion received over said support sleeve with said external ribs on said support sleeve received in said tube internal grooves, a cover member positioned over said support, said cover member having cooperating opposed parts with a cover opening therebetween receiving said tube end portion, and said cover opening having longitudinally-spaced inwardly extending circumferential ribs received in said tube external grooves.
- 28. An electric sump pump having a liquid level sensing alarm switch mounted thereon, an alarm remote from said pump and said alarm switch, said alarm being electrically connected with said alarm switch, said alarm switch being operable to activate said alarm in response to a predetermined liquid level externally of said pump, an alarm enclosure in which said alarm is mounted, a battery in said enclosure to operate said alarm, and an alarm and battery testing button on said enclosure.
- 30. An electric sump pump having a housing, a liquid level sensing alarm switch assembly fixedly mounted on said housing against movement relative thereto, said alarm switch assembly including an alarm switch, an alarm remote from said pump and said alarm switch assembly, said alarm being electrically connected with said alarm switch, said alarm switch being operable to activate said alarm in response to a predetermined liquid level externally of said pump, a switch support secured to said housing and extending outwardly therefrom, and said switch assembly being mounted on said switch support externally of said housing.
