ᐅ Toilet drain pipe clogged with urine scale buildup

The waste pipe from our toilet became completely clogged with limescale deposits and recently required extensive cleaning. However, our house is only 10 years old, so a waste pipe shouldn’t become fully blocked in such a short time, right? The plumber said it was due to the pipes and their rough surfaces, something that wouldn’t be used nowadays. Now the question is whether I should replace the pipes or if there is a way to prevent limescale buildup. Does anyone have any advice?

Heavy buildup of urine scale can also be worsened by using only the water-saving flush button; in this case, not enough water flows through to properly rinse the pipe.
Occasionally using the full flush capacity would be better.
Try this first before spending a lot of money on new pipes.
