Customer Reviews

Pressure Balance Unit for Single-Control Tub/Shower Valve is rated 4.8 out of 5 by 13.
Rated 5 out of 5 by from This item saved me hundreds in costly repairs! I am no plumber by any means. Similar to justme's review I experienced an obstruction which caused very low or no (hot or cold) water pressure. I replaced the old pressure unit with this item along with a new AS cartridge for good measure (and piece of mind) and now we can take hot showers in Niagara Falls if we want. The only other option I had was a costly one involving a complete valve body replacement, destroying/replacing perfectly good bathroom tile, some drywall work and cutting/soldering copper pipe. Going in from the other side of the wall is not an option because that area is covered up by our kitchen cabinets with granite counters. Here's a Pro-tip I learned from the internet: Dab a bit of petroleum jelly on a Q-tip and coat the black O-rings so that they won't dry out and therefore last longer that way.

Rated 5 out of 5 by from Inexpensive and gets job done Exactly what I needed to restore the pressure in our shower. Straightforward installation and great price. I avoided having to cut tile and replace the whole valve body by replacing this.

Rated 5 out of 5 by from Pleased I could find the product I needed. I am surprised it is not a regular inventory item at the store. The Pressure Balance unit for single-control tub/shower valve contains small backflow valves that act a little like a strainer when your home has rusting galvanized iron pipe. Occasionally, you must clean the the valves to preserve the water flow rate through the unit. Infrequently, you will damage the check valves when trying to clean them. A replacement unit is certainly helpful!

Rated 5 out of 5 by from Quick and easy solution I had less Hot water pressure vs. Cold water pressure. Manufacturer recommended checking for obstruction or damaged O-ring. I chose to get a new one just in case the O-ring was damaged and difficult to find/replace. I found the obstruction, but , decided to install the new valve ,because the calcuim build up from the hard water. Now, Hot water pressure is great!
