The M-Core U231 and U361 transfer valves were introduced in 2020 and are designed to divert water from one shower device to another (example: body sprays to a showerhead). Both the U231 and U361 transfer valves require either a PosiTemp or an M-Core shower valve to provide water to supply to the system.
- The water supply must be turned off- see article How to Turn Off the Water Supply to the Faucet.
- Recommended Tools: 3/32" Hex Wrench, Needle-Nose Pliers
- We recommend covering the drain before beginning so to not lose any parts down the drain.
Set Screw: Under Lever
Note: Some models have a removable cap on the front of the handle and a set screw under the lever. It is not necessary to remove the cap.
If this is not your handle mechanism, see Vertical Spa: Transfer Valves article to learn more about the different handle mechanism types.
