Is this Calcium?

[Robert1999]

See attached picture. Is this calcium? It's only one the hot water said and under every sink. Do I need to do anything like replace the lines?

Thanks.

this is what ends up in your hot water tanks also .

Thanks, we did have to recently replace the hot water heater.

Is just cleaning the calcium off enough or should these flex lines be replaced?

it would be your choice, but for ~$10.00, new supply lines with a touch of Rectorseal as a lubricant on the threads will allow your worries to go away for several years. Just think of what a burst line could do to your residence if left unchecked overnight?

^^ what he said.

$10 a line or

$?????? dollars damage.

flush your tank annually and it will last longer and be cheaper to run.
