I was trying to use this to fix a problem with an RV toilet. Every time we flush water, our water supply system is subjected to shock waves. I was hoping this would help, but it didn't. It didn't really matter, after two attempts to insert it into the system in different ways, it had no effect. I followed the instructions exactly, but failed miserably. Very disappointed. Considering how small the RV's water system is, I was sure it would help, but no luck.
