Ripples in new cylinder

[glnovice90]

Hi,

Just bought a new copper cylinder and looking inside, the central heating coil is rippled. From what I understand ripples are bad and can result in erosion over time. Since I want this cylinder to last 20 years would it be better to return it? Am I making something out of nothing?

Thanks,

I would be contacting the manufacturer / place of purchase about that? Doesn't look great although probably fine to use.
