A battery of fixtures can contain up to how many fixtures?

In plumbing terminology, a "battery of fixtures" refers to a group of plumbing fixtures that are grouped together and can share a common supply line and waste outlet. The Texas plumbing code allows a specific number of fixtures to be connected to a single supply line before requiring additional considerations for pressure, flow, and venting.

The correct choice indicates that a battery of fixtures can contain up to eight fixtures. This limit is designed to ensure that each fixture receives adequate water supply and drainage, and helps maintain proper pressure throughout the system. Exceeding this number without appropriate adjustments could lead to diminished performance in water delivery and drainage efficiency across the fixtures. It also helps to standardize installations for safety and effectiveness, ensuring compliance with plumbing regulations.

The other choices do not align with the maximum allowed number according to the code, establishing a clear regulatory guideline for plumbing installations.
