An isometric detail of a domestic water piping expansion loop features the plumbing line routing in a U-shaped offset configured to absorb thermal expansion and contraction in long pipe runs. The loop includes elbows and straight pipe segments dimensioned at 8'-7 3/16" for the primary run and 4'-3 19/32" for the loop projection. This configuration prevents stress and potential failure in the plumbing system caused by temperature fluctuations.
