If it isn''t, the flow will be restricted and the valve won''t relieve as much capacity as it''s supposed to. The outlet piping should not produce any strain due to thermal expansion. As the medium expands, if the piping doesn''t have any give, the valve can warp and leak. Pressure Relief Valve Operation
