## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    This works great!
  

*by K***I on Reviewed in the United States on April 8, 2021*

This is a no-brainer: a locking cap so people cannot mess with your fresh water supply; a must have for any RVer.Note: when you remove the existing water cap the hose that connects the water tube will likely not fit. To connect this new water cap with the existing water hose I bought a ProSource Tubular Drain Pipe Connector, which is a quick and easy way to extend/connect 1 1/2" or 1 1 1/4" pipes.

    Excellent locking mechanism, easy install, looks great!
  

*by A***R on Reviewed in the United States on July 31, 2021*

Bought this as a replacement part. Love the spring lock! Need to press key against edge for it to slide into lock (see pic). Very quick and easy install. It was difficult to see if the old one was securely locked... and we ended up losing cap on the freeway.We got black to match the surrounding area and it looks and works great! Definitely recommend!

    DIY project level intermediate
  

*by C***. on Reviewed in the United States on November 10, 2023*

Somebody else already posted in detail how to install this.(Thank You!!)  I just followed their instructions and everything went fine. NOTE: the drill holes likely won't fit your travel trailer so you will have to drill new holes. Also, you will likely need to purchase an adapter for the intake hose as it does not fit.
