How long do they last before replacement?

I really cannot say. I installed one over a year ago and it is still working like new. I pulled it out about five months ago and it looked clean, so I put it right back. I estimate a lifetime of at least3 years before I might want to replace it.

Will this prevent water backup in an RV shower drain?

Hi, This shower sink drain is suitable for standard 1.45”to 2.7" pipe, please reference to your RV shower drain. Will prevent backflow of sewers, filter and prevent blocking.
