Abstract

A flushing device includes an enclosure having an inner surface and an outer surface, the inner surface defining an interior of the enclosure and the outer surface defining an exterior of the enclosure, the inner surface and the outer surface further defining an access opening proximate an upper portion of the enclosure; a discharge conduit; a platform situated within the enclosure, the platform having a top surface and a bottom surface, the platform movable to proximate the access opening; and a U-shaped rigid fluid routing support pipe mounted to the platform and in fluid communication with the discharge conduit.

First claim

That which is claimed is:

1. A flushing device comprising:
an enclosure having an inner surface and an outer surface, the inner surface defining an interior of the enclosure and the outer surface defining an exterior of the enclosure, the inner surface and the outer surface further defining an access opening proximate an upper portion of the enclosure;
a discharge conduit;
a platform situated within the enclosure, the platform having a top surface and a bottom surface, the platform movable to proximate the access opening; and
a U-shaped rigid fluid routing support pipe mounted to the platform and in fluid communication with the discharge conduit, the U-shaped rigid fluid routing support pipe disposed substantially below the platform, a portion of the U-shaped rigid fluid routing support pipe extending through the platform.

2. The flushing device of claim 1 , further comprising:
a backflow preventer mounted on the top surface of the platform, an inlet of the backflow preventer in fluid communication with a fluid system and an outlet of backflow preventer in fluid communication with the discharge conduit; and
a dechlorinator mounted on the top surface of the platform, the dechlorinator in fluid communication with the discharge conduit.

3. The flushing device of claim 1 , further comprising a freeze control valve mounted on the platform and in fluid communication with the discharge conduit, the freeze control valve openable under freezing conditions to allow fluid communication between a fluid system and the discharge conduit.

4. The flushing device of claim 1 , further comprising a fluid system conduit extending from the interior of the enclosure to the exterior of the enclosure, the fluid system conduit connectable with a fluid system.

5. The flushing device of claim 4 , further comprising a freeze control valve mounted on the platform and in fluid communication with the discharge conduit and the fluid system conduit, the freeze control valve openable under freezing conditions to allow fluid communication between a fluid system and the discharge conduit.

6. The flushing device of claim 4 , further comprising:
a flushing controller; and
a flushing valve mounted on the platform and in fluid communication with the fluid system conduit, the flushing valve operatively connected to the flushing controller, the flushing valve controllable by the flushing controller.

7. The flushing device of claim 6 , further comprising an encoder receiver transmitter operatively connected to the flushing valve.

8. The flushing device of claim 6 , further comprising a meter mounted on the top surface of the platform, the meter in fluid communication with the flushing valve and the discharge conduit.

9. The flushing device of claim 1 , further comprising a plurality of U-shaped rigid fluid routing support pipes mounted on the platform, wherein at least one of a meter, a flushing valve, a dechlorinator, a backflow preventer, and a freeze control valve is connected to an end of the portion of the U-shaped rigid fluid routing support pipe extending through the platform.

10. The flushing device of claim 1 , wherein:
the enclosure includes an upper platform stop proximate the access opening;
the platform includes a notch;
the notch is sized to accept the upper platform stop; and
the platform is rotatable to stop the platform against the upper platform stop proximate the access opening.

11. A flushing device comprising:
an enclosure having an inner surface and an outer surface, the inner surface and the outer surface defining an access opening proximate an upper portion of the enclosure;
a platform within the enclosure, the platform having a top surface and a bottom surface, the top surface facing the access opening;
a flushing valve mounted on the platform; and
a U-shaped rigid fluid routing support pipe mounted on the platform and in fluid communication with the flushing valve, the U-shaped rigid fluid routing support pipe accessible from the access opening, the platform movable proximate to the access opening by interaction with the U-shaped rigid fluid routing support pipe,
wherein the platform defines an access hole through the platform, the access hole providing access to the U-shaped rigid fluid routing support pipe from the access opening.

12. The flushing device of claim 11 , further comprising a freeze control valve in fluid communication with the flushing valve.

13. The flushing device of claim 11 , further comprising a plurality of U-shaped rigid fluid routing support pipes mounted on the platform and in fluid communication with the flushing valve, the plurality of U-shaped rigid fluid routing support pipes accessible from the access opening, the platform movable proximate to the access opening by interaction with at least one of the U-shaped rigid fluid routing support pipes.

14. The flushing device of claim 11 , further comprising:
a meter mounted on the top surface of the platform;
a backflow preventer mounted on the top surface of the platform; and
a dechlorinator mounted on the top surface of the platform.

15. The flushing device of claim 14 , wherein the U-shaped rigid fluid routing support pipe connects the meter to the backflow preventer.

16. The flushing device of claim 14 , wherein the U-shaped rigid fluid routing support pipe connects the backflow preventer to the dechlorinator.

17. A flushing device comprising:
an enclosure having an inner surface and an outer surface, the inner surface and the outer surface defining an interior and an exterior of the enclosure, the inner surface and the outer surface further defining an access opening proximate an upper portion of the enclosure, the inner surface and the outer surface further defining a conduit outlet and a conduit inlet;
a discharge conduit;
a fluid system conduit, the fluid system conduit connectable with a fluid system;
a platform situated within the enclosure, the platform having a top surface and a bottom surface, the top surface facing the access opening and movable to proximate the access opening;
a flushing valve mounted on the platform, the flushing valve having a flushing valve inlet and a flushing valve outlet, the flushing valve inlet in fluid communication with the fluid system conduit, the flushing valve outlet in fluid communication with the discharge conduit;
a freeze control valve mounted to the bottom surface of the platform, the freeze control valve having a freeze valve inlet and a freeze valve outlet, the freeze valve inlet in fluid communication with the fluid system conduit, the freeze valve outlet in fluid communication with the discharge conduit, the freeze control valve openable under freezing conditions to allow fluid communication between the fluid system conduit and the discharge conduit;
a mounting bracket attached to the bottom surface of the platform; and
a U-bolt attached to the mounting bracket, the U-bolt supporting the freeze control valve beneath the mounting bracket.

18. A flushing device comprising:
