What is the maximum horizontal spacing interval for PVC hydronic piping?

2.67 feet
3 feet
4 feet
6 feet

The correct answer is: 3 feet

The maximum horizontal spacing interval for PVC hydronic piping is 3 feet. This measurement is crucial because it ensures proper support for the piping system and helps to prevent sagging or stress that could lead to damage over time. Maintaining this spacing helps to distribute the weight of the piping effectively and allows for thermal expansion and contraction without compromising the integrity of the piping material. This standard is typically in accordance with the manufacturer's specifications or building codes that govern piping installation practices. Observing the correct spacing helps ensure that the system operates efficiently and prolongs the life of the materials used.
