Review on 🔧 Prier 630-7500 Vacuum Breaker Service Parts Kit | Compatible with Series 400/500 | Original Version by Matthew Fadoul

This set fits perfectly, is easy to install and prevents the faucet from leaking completely. If you have determined that a vacuum switch is the cause of a leaking faucet, this is the perfect solution. I figured I'd have to replace the entire faucet and spend a few bucks, but for a few bucks you're done. I found instructions on how to replace it online. Basically, you use a screwdriver to pry off the black or gray cover, with the latch wide open, unscrew the white plastic part (don't worry, it won't break, but it will bend) and replace the parts with the ones inside the gear. Channel locks to tighten the white plastic piece and you're done. First, it's easier to insert a small rod into a short cylindrical piece attached to the pipe than to insert it into a cap and try to put it in place without tipping it over. That's what happened when I first assembled it. It flowed worse than at the beginning. I found the stem almost sat sideways when I assembled it. Used the recommended procedure above and everything went perfectly. Saved from a plumber call that can cost $100 just to get him there. I definitely recommend this set.
