A flush system comprising:

• a meter valve to selectively open to direct water flowing therethrough to an outlet pipe;
• a receptacle open to the outlet pipe;
• first and second pipes in fluid communication with the meter valve;
• and
• a ball valve assembly disposed between the first and second pipes, upstream of the meter valve, in fluid communication with the meter valve and a water supply source, and arranged with the pipes to isolate the meter valve from the water supply source.

A waste disposal system comprising:

• a receptacle to receive waste;
• a meter valve defining an outlet open to the receptacle, and configured to selectively open the outlet for water to flow therethrough;
• first and second inlet pipes in fluid communication with the meter valve and a water supply source, the second inlet pipe extending from a wall;
• and
• a ball valve assembly proximate the wall and secured to the first inlet pipe upstream of the meter valve and secured to the second inlet pipe downstream of the supply source, wherein the ball valve assembly is configured to selectively isolate the meter valve from the supply source.
