How often should I replace sewer hose?

[Moodywelman]

They are available everywhere, buy a new one when/if you need it.

As a surprise, Walmart usually has a top brand of sewer hose on the shelf.

I don't know that we have had to replace and of our two flush hoses in ten years, so my answer is to replace when necessary. Our two lengths of hose are carried in the tide under our FC. I also carry a replacement.
