## Description

PR-500

Review: Make sure you're ok with a 10 psi pressure drop requirement - I was really hoping this would work for me - I went to the mfr's website to check out details and it described it as only needing a 3 psi pressure drop to activate, which is exactly what I needed (residential application, feeding off a kitchen sink branch line to prime a floor drain in the basement). When it arrived, I couldn't get it to work and noticed the packaging stated it needed 10 psi drop to activate. I called the mfr and learned it was a brand new version that only required the 3 psi (but using the same model #). That's what they had on their website and what I was expecting. What I got from the seller was the older version of the same model, so it wouldn't work for me. LET ME STRESS THIS WAS NO FAULT OF THE SELLER! When I contacted them, they replied very promptly and apologized but said the version I got was the only type they had, and very helpfully advised that I could return it (which I've now done). Things like this happen, not really anyone's fault (although maybe the manufacturer could've changed the model # since the spec changed). So I appreciate the good customer service I got from the seller (Plumber's Paradise) and would 100% buy from them again.
Review: Welp! That was easy. - The old one was 30 years old and somehow still working. That being said, since I was remodeling; I put in a new one. Looking forward to another 30 years.

### ⭐⭐⭐⭐⭐ Secret weapon for stopping random off-gassing smell in bathrooms
*by N***V on September 24, 2020*

We will be using these in a condensation drain line. Despite a P trap there was a funky sewer smell emanating from time to time. This trap primer valve solves the problem. Pricey but highly recommend.
