When installing PEX that is one inch in diameter or smaller in a horizontal run, supports must be placed at intervals no greater than how many inches?

Proper support spacing for PEX in horizontal runs is about keeping the pipe secure to prevent sagging and stress on fittings as it expands and contracts with temperature. For PEX that is one inch in diameter or smaller, supports should be placed no more than 32 inches apart. This spacing helps the pipe stay aligned and reduces the chance of movement that could loosen fittings or cause leaks. Shorter spacing like 18 inches adds unnecessary hangers, while longer spacing such as 44 inches risks sagging; 28 inches isn’t the standard interval for this size, so 32 inches is the correct guideline.
