Abstract

An adapter for use in association with upstream and downstream portions of a piping system is disclosed. The adapter includes a first chamber having an inlet adapted to receive fluid therethrough, an outlet adapted to expel fluid therefrom, and a sidewall extending therebetween defining a first chamber interior. The adapter also includes a second chamber having an inlet adapted to receive forced fluid therethrough, an outlet adapted to expel the forced fluid therefrom, and a sidewall extending therebetween defining a second chamber interior. The first chamber interior is isolated from the second chamber interior. The first chamber is adapted to receive forced fluid therethrough from an upstream portion of a piping system, and the second chamber is adapted to provide forced fluid therethrough to a downstream portion of the piping system.

Claims (28)

1. A method of treating a piping system, comprising:

removably providing an adapter between an upstream portion of the piping system and a downstream portion of the piping system, the adapter comprising:

a first chamber having an inlet adapted to receive fluid therethrough, an outlet adapted to expel fluid therefrom, and a sidewall extending therebetween defining a first chamber interior; and

a second chamber having an inlet adapted to receive forced fluid therethrough, an outlet adapted to expel the forced fluid therefrom, and a sidewall extending therebetween defining a second chamber interior, wherein the first chamber interior is isolated from the second chamber interior; and

forcing at least one of fluid through an upstream portion of the piping system and through the inlet of the first chamber, and fluid through the outlet of the second chamber to a downstream portion of the piping system.

2. The method of claim 1 , further comprising removing a removable element between the upstream portion of the piping system and the downstream portion of the piping system, prior to the step of providing the adapter between the upstream portion of the piping system and the downstream portion of the piping system.

3. The method of claim 2 , further comprising removing the adapter and replacing the removable element.

4. The method of claim 2 , wherein the inlet of the first chamber is adapted to receive liquid therethrough, the outlet of the first chamber is adapted to expel liquid therefrom, the inlet of the second chamber is adapted to receive forced gas therethrough, and the outlet of the second chamber is adapted to expel forced gas therefrom.

5. The method of claim 1 , wherein the adapter is configured to be received by a housing used to form a portion of a back flow prevention device.

6. A method of treating a piping system, comprising:

providing an adapter between an upstream portion of the piping system and a downstream portion of the piping system, the adapter comprising:

a first chamber having an inlet adapted to receive fluid therethrough, an outlet adapted to expel fluid therefrom, and a sidewall extending therebetween defining a first chamber interior, wherein the inlet of the first chamber is provided in fluid engagement with an upstream portion of the piping system, such that liquid may pass therethrough through the upstream portion of the piping system; and

a second chamber having an inlet adapted to receive forced fluid therethrough, an outlet adapted to expel the forced fluid therefrom, and a sidewall extending therebetween defining a second chamber interior, wherein the outlet of the second chamber is gaseously engaged with a downstream portion of the piping system, wherein the first chamber interior is isolated from the second chamber interior; and

forcing at least one of fluid through an upstream portion of the piping system and through the inlet of the first chamber, and fluid through the outlet of the second chamber to a downstream portion of the piping system, wherein the upstream portion of the piping system is isolated from the downstream portion of the piping system.

7. The method of claim 6 , further comprising removing a removable element between the upstream portion of the piping system and the downstream portion of the piping system, prior to the step of providing the adapter between the upstream portion of the piping system and the downstream portion of the piping system.

8. The method of claim 7 , further comprising removing the adapter and replacing the removable element.

9. The method of claim 6 , wherein the inlet of the first chamber is adapted to receive liquid therethrough, the outlet of the first chamber is adapted to expel liquid therefrom, the inlet of the second chamber is adapted to receive forced gas therethrough, and the outlet of the second chamber is adapted to expel forced gas therefrom.

10. The method of claim 6 , wherein the adapter is configured to be received by a housing used to form a portion of a back flow prevention device.

11. A method of treating a piping system, comprising:

providing an adapter between an upstream portion of the piping system and a downstream portion of the piping system, the adapter comprising:

a first chamber having an inlet adapted for receiving forced liquid therethrough and an outlet adapted for fluidly engaging the shut-off valve, wherein the inlet of the first chamber is fluidly engaged with an upstream portion of the piping system; and

a second chamber having an inlet adapted for receiving forced gas therethrough and an outlet adapted for gaseously engaging a portion of the piping system, wherein the outlet of the second chamber is gaseously engaged with a downstream portion of the piping system; and

forcing at least one of fluid through an upstream portion of the piping system and through the inlet of the first chamber, and fluid through the outlet of the second chamber to a downstream portion of the piping system.

12. The method of claim 11 , wherein the upstream portion of the piping system is isolated from the downstream portion of the piping system.

13. The method of claim 11 , further comprising removing a removable element between the upstream portion of the piping system and the downstream portion of the piping system, prior to the step of providing the adapter between the upstream portion of the piping system and the downstream portion of the piping system.

14. The method of claim 13 , further comprising removing the adapter and replacing the removable element.

15. The method of claim 11 , wherein the inlet of the first chamber is adapted to receive liquid therethrough, the outlet of the first chamber is adapted to expel liquid therefrom, the inlet of the second chamber is adapted to receive forced gas therethrough, and the outlet of the second chamber is adapted to expel forced gas therefrom.

16. The method of claim 11 , wherein the adapter is configured to be received by a housing used to form a portion of a back flow prevention device.
