PRODUCT FEATURES
The prismatic faceting of the Trillian™ Bath Collection is an evolution of modern style that creates an edgy look which catches the light as well as the eye. Delta® showers with Monitor® pressure-balance valves are engineered to make sure you don’t experience a sudden and possibly unsafe change in water temperature as a result of running water elsewhere, such as using a dishwasher, flushing a toilet or running a washing machine. By integrating separate controls on one trim with the MultiChoice® Integrated Shower Diverter, we’ve streamlined installation and your shower style. With the MultiChoice Universal system, you have the freedom to upgrade style and functionality later. And, because there’s no need to alter plumbing behind the wall, you save time, effort and money on future renovation updates. With separate volume and temperature control on this model, simply set the water at your preferred temperature and turn the shower on or off with the volume control handle — without interrupting your set temperature. You can install with confidence, knowing that Delta showers are backed by our Lifetime Limited Warranty.

Hello....customer is experiencing low flow out of the cold side, do they need to replace the cartridge, and if so which one would that be
Hi Carol,
The correct cartridge is RP46463.
I have included the flushing instructions below this can resolve the issue also.
To flush the open valve without the cartridge, please follow the directions below.
1) Remove the handle by loosening the set screw on the side of the base of the handle. The set screw is either a 1/8" or 3/32" Allen screw. So you will need to use the appropriate size Allen wrench to loosen it. Loosen it just enough to be able to easily pull the handle off. * Note. If there is calcium build-up at the base of the handle, it may be necessary to soak it in a 50/50 solution of vinegar and water. Simply saturate the rag with the 50/50 solution, wrap it around the handle base and place a plastic bag over it. I would recommend do this the night before removing the handle.
2) After removing the handle, remove the trim sleeve.
3) Then you will need to remove the bonnet nut. The bonnet nut is the threaded ring at the valve opening. It unscrews counterclockwise. You will need a pipe wrench or a pair of channel locks.
4) After removing the bonnet nut, you will need to pull the cartridge straight out. You may need a small, skinny bladed screwdriver to wedge in between the lip of the cartridge and the valve to help start it out.
5) Once the cartridge is removed, you will have an open valve body.
6) Next, shut the shower door or curtain and turn the water on to the valve. Water should gush out, much like an open fire hydrant. Have someone observe if there is good water pressure coming out of the valve and let it flush for 30 seconds.
7) Re-install the cartridge and re-assemble in reverse of how it was disassembled. The Tub/Shower should then have a good flow. If it does not, the cartridge will need to be replaced.
Please contact us back if you have any questions or need further assistance.
We appreciate your business and look forward to continuing to serve you.
