## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Easy to install, right parts for the job
  

*by S***R on Reviewed in the United States on January 18, 2017*

My 800M4 failed in a rare hard freeze here in south Texas.  I was surprised to find I could buy replacement parts and upgrade to a freeze resistant version at the same time.  While I was a little concerned because the parts are plastic, I researched and learned that the plastic in use here is specially designed to be as strong as metal, not corrode, and work well in this constantly wet environment. I got the parts, replaced them in about 5 minutes (in the dark no less) and it worked perfectly the first time.  The manual is easy to understand and this is certainly a DIY job. I highly recommend fixing your Watts PBV rather than hiring a contractor to replace it if.

    Perfect Replacement!

    Perfect fit
  

*by M***I on Reviewed in the United States on October 16, 2022*

It’s perfect replacement part and works great. But it lasts only 2 years in extreme weather conditions.
