The central support member may include an upper engagement member to engage a sink faucet, and a lower engagement member to engage a main sink drain that is in fluid communication with an air conditioner drain line. The forward support member may include a forward engagement member to engage a sink overflow drain that is in fluid communication with the air conditioner drain line. The rear support member may include a rear engagement member to engage a rear wall of a sink. By using the sink apparatus to cover the main sink drain and the overflow sink drain, overflow or escape of debris from the air conditioner drain line through the main sink drain and the overflow sink drain is prevented when compressed air is applied to the air conditioner drain line. ## Claims ### Claim 1 A sink apparatus for containing debris when compressed air is applied to a drain line that is connected to a sink drain, the sink apparatus comprising: a central support member having an elongated body member, an upper engagement member and a lower engagement member, one of the upper engagement member and the lower engagement member being moveable relative to the elongated body member of the central support member;
