Abstract:
Disclosed are cleaning devices and methods of use thereof for cleaning a vertical stack plumbing system. The cleaning device includes a first cylindrical body defining a first opening for selectively introducing a predetermined amount of cleaning medium into the cleaning device; a second cylindrical body defining a second opening configured to maintain airflow and venting of the vertical stack plumbing system when the cleaning device is in use, the first and second cylindrical bodies being directly connected to a main body of the cleaning device and in fluid communication with one another through the main body; and an attachment member defining a third opening that is directly connected to the main body of the cleaning device, the attachment member configured for direct removable attachment to a plumbing waste pipe in the vertical stack plumbing system and for receiving the cleaning medium therethrough to introduce the cleaning medium into the vertical stack plumbing system.

Claim (Index 12):
The method of  claim 11 , further comprising upon completing step (f) or step (g) the following:\n (h) introducing a second cleaning medium that is pea gravel and/or glass into the first cylindrical body of the device; (i) applying a vacuum from the vacuum source to the vertical stack plumbing system to facilitate passing of the second cleaning medium through the vertical stack towards the vacuum; (j) selectively introducing the second cleaning medium into the vertical stack plumbing by opening a partition positioned in the first cylindrical body such that a predetermined amount of cleaning medium flows through the first cylindrical body into the main body of the device and from the main body into the attachment member of the device while the second cylindrical body of the device concurrently maintains airflow and vents of the vertical stack plumbing system; and (k) following step (j), passing the second cleaning medium from the attachment member into the vertical stack plumbing system towards the vacuum thereby cleaning and/or abrading inner surfaces of the vertical stack plumbing system while moving towards the vacuum.
