Wrong instruction sheet
Valve did not match the instruction sheet, so as a homeowner, and not a professional plumber, it took a little guess work and Google time.

Water-saving Valve makes pressure independent of temperature
I bought this valve because it enables you to set the pressure (flow) of the water independently from the temperature. I hate that all the options from the big box stores require you to turn the water all the way on in order to simply get hot water. I believe in only using what I need, and this valve (combined with the right hardware inside the shower) permits me to have hot water at a much lower flow rate. I'm just now getting again for the remodel of another bathroom.

Q&A
I have an old delta valve with a push/pull diverter button, what can I use to replace it with a diverter on the spout
Thank you for your inquiry, Timmer! The Delta Push-Button Diverter Cap RP2865 can be purchased to cap off the diverter area of your original valve and a diverter tub spout can be installed instead.
Best regards,
Tanya

What can I do if my valve body is set too deap
I have a shower only application with multiple heads. Installed was a R10000-UNWS valve body and then a R11000 diverter. The shower walls were floated and then tiled. I followed the installers recommendations for the depth of the valve body and the diverter. After the tile was installed the valve body and diverter are now set too deep (about 1 1/4 inch) into the wall. Is there anything that can be done to allow the trim kit and handle it fit without having to tear into the wall and reset the valve body and diverter?
I purchased Delta trim kit T17T253 for info.
Hi Josh, Thank you for your question. We do offer extension kits that will help with your issue. The extension kit for the diverter trim is the RP75137. The extension kit for the T17T253 trim is the RP75136.
Thanks,
Dave

Can we use either the R10000-UNBX or the R10000-LBX rough in valve for the Delta Lahara shower combo trim? We want to make sure we have the functionality of volume and temperature control on the handle..
Hello Mary,
Thank you for your inquiry! Yes, either Delta MultiChoice Universal Valves R10000-UNBX or R10000-LBX can be used with any of our dual control 17 Series and 17T shower or tub/shower faucets.
Best regards,
Tanya

If I am installing for shower only, can I just cap the tub outlet at the valve? Should I have purchased the highflow model instead? Thanks
Tanya you didn't answer the question! Should Sparky have purchased the shower only model instead? Do you lose the high pressure feature on the dual valve by capping off tub diverter?

What cartridge fits this valve? I keep buying them and my contractor informed me I keep purchasing the incorrect one.
Hi, Mandy!
Thank you for your question. The R10000 MultiChoice Rough Valve Body takes multiple valve cartridge assemblies. The correct valve cartridge assembly depends on your Valve Trim kit. If you purchased a Monitor 13/14 Series trim kit, you will need RP46074. If you have a Monitor 17 Series trim kit, you will need the RP46463. If you have the TempAssure 17T series unit, you will need the RP47201. Here are the links to each cartridge:

Multi Choise R10000 LBX or UNBX is there a difference ? for use installing a Yorkshire-Chrome-1-Handle-Bathtub-and-Shower-Faucet/1000165769
Hi, AL!
Thank you for your question. The Delta MultiChoice Universal R10000-UNBX Rough-In Valve Body and the Delta Universal MultiChoice R10000-LBX Rough-In Valve Body are the exact same. The Delta Universal MultiChoice R10000-LBX Rough-In Valve Body is exclusive to Lowe's Home Improvement store. Both rough -in bodies feature the same quality parts, materials, and workmanship, no matter what kind of dealer sells them.

One last question. My tile guy has already installed R10000-UNBX and placed the cement, can I still connect the R11000? If not, what is the best thing to do with these parts: T14259-LHD, R10000-UNBX, 55085 and 50560.
Hi, Belle28!
Thank you for your question. The Delta R11000 Diverter Rough would need to be installed the wall. If this cannot be done, we recommend to us a 3 Way Shower Arm Diverter to install the Monitor T14259-LHD, MultiChoice Universal R10000-UNBX Rough In Valve, 55085 and 50560.

The BX on the R10000 indicates that is a Single Box Model. What exactly is a single box model?
Also, I'm in the process of a remodel for a bathroom. What components will I need to have a shower and a hand held shower?
I'm thinking about the Vero trim for the shower and hand held.
Thank you for your input.
SK
Hi SK, Thank you for your question. The single box is just that, you can purchase 1 R10000. The model R10000-UN can only be purchased 12 at a time. If you are installing a shower only we recommend using the R10000-UNBXHF which will give a higher flowrate for the multiple showerheads, this valve cannot be used in a tub installation. Trim choices in the Vero collection include T14253 and T14253-H2O in the 14 series. If you want temperature and volume control the 17 series offers the models T17253 and T17253-H2O. The H2O kinetic showerheads are the differences between the models. If you want to control the showerheads to work individually or together you will also need a R11000 rough in and a T11853 diverter trim. Finally for the handshower you can choose the wall mount 55530 or the slide bar version 57530, and the wall elbow 50570.
Thanks,
Dave

What is the GPM this valve delivers to the tub fill spout
Thank you for your question, Mike. The flow rate will depend on the trim kit used, the pressure in the home, and other factors. At 60 PSI the maximum flow rate will be about 6.0 GPM with a Monitor pressure-balance unit and 8.5 GPM with a TempAssure thermostatic unit.
Best regards, Jon

Living in a new construction home, 2 of the 3 showers only have this roughed in (no fixtures) The 3rd shower has fixtures installed. My question is for the showers with the roughed in valves (no fixtures) will your hot and cold water mix when turned on?
Thank you for your question, ahbe! The rough-in will allow both hot and cold water into the valve. This should be tested with the provided test cap per the instructions. Without the cartridge that is included with a trim kit, however, you will not be able to adjust the temperature.
Best regards, Edward

Just purchase a R10000-unbx. How do I re-seat the Screen (RP46077) into the R10000-UNBX?
Hi, Screenreseat!
Thank you for your question. The screen can be pushed right into the top hole of the valve body assembly. This is only needed unit right before you install your valve cartridge assembly into the valve body.

Hi, Corky!
Thank you for your question. The hot and cold water lines can be reversed for the Delta MultiChoice Universal R10000 rough in valve body. However, the hot and cold indicator on the handle trim kit will be opposite.

how ' universal " are the new trims? if the customer has a valve installed, 17oo series, can a new trim be installed in a pre universal valve? say a new style 1400 trim with new cartridge?
Thank you for your question, JimW! The R10000-UNBX valve body will work with any current Delta valve trim in the 13/14, 17 and 17T series. The pre-multi choice cartridges, manufactured for older 1300/1400 series and 1700 series will not fit into an R10000-UNBX valve body. Our current 13/14 series trims would be able to fit over a pre-multi choice valve in the same series, however the pre-multi choice cartridge would need to be used, rather than the multi choice cartridges included in the new trim kits. If you need further assistance, feel free to contact us directly.

Can I use a 1/2 FPT to 3/4 PEX adapter to plumb the tub spout instead of 1/2 copper
Hello Marv,
Thank you for your inquiry! When installing a tub spout, the drop from the bottom port of the valve must be 1/2" copper or 1/2" galvanized pipe as the internal diameter of the pipe is important to prevent back-pressure.
Best regards,
Tanya

WHAT IS THE GPM
Thank you for your question, MRS B. The R10000-UNBX valve will provide various flow rates, depending on the trim kit used and the PSI available to the home. At 60 psi, a 13/14 series can produce up to 5.8gpm but at 80 psi this can go as high as 6.8 gpm. A 17 series can produce approximately 5.9 gpm to 6.8 gpm at these rates whereas the 17T trims can produce anywhere from 7.3 gpm to 8.5 gpm.

Will R10000-UNBX work with T13691-SOS-15 trim kit (Monitor 1300 series trim on box.)
Good afternoon,
I bought the R10000-UNBX rough in valve. I also bought the T13691-SOS-15 trim kit (Monitor 1300 series trim only tub/shower w/ cartridge fits multi choice Universal valve - on box.) From my research it seemed like the rough in valve worked with all the new trim kits. I'm not sure it will work with this one as there is a diverter valve hole in the trim plate. And I do not see a diverter valve with trim kit or rough in valve.
If I need to buy the diverter valve could you please provide the part number?
Hi Staceman, Thank you for your question. The T13691-SOS-15 is one of our commercial tub/shower faucet trims. The rough that includes the push button diverter that goes with the trim is the R10300-UNWS. The R10000-UNBX will work with any of our other new trims.
Thanks,
Dave

I see 13 different Delta MultiChoice R10000 models, what is the difference between the models?
Thank you for your question. We do offer many different kinds of R10000 rough in valves and it depends on what kind of piping you are using as to which one you use. Here is a list of what all the letters mean after the R10000 number.
UN-universal valve can be used with copper, iron pipe, pex or cpvc piping
BX-is an individual box instead of a case of 12 rough-in
WS-screwdriver stops means you can turn the water off at the valve instead of shutting off the water in the whole house.
HF-high flow valve can only be used with a shower only faucet.
T-thin wall mounting kit included.
IP-can only be installed with a iron pipe.
PX-can only be installed with pex piping
MF-used for pex cold expansion connections

I bought two R10000 valves, can I use one as diverter valve for hand-held device?
Dear Mick,
Thank you for your inquiry! The Delta MultiChoice Universal Valve R10000-UNBX is designed for hot and cold water side port connections only. You would need the Delta 3/6 Setting Diverter R11000 valve to install/add a hand shower to your shower unit.

What is the maximum flow rate when installing with multiple shower heads and a 3 way diverter?
Thank you for your question, Jamie! A Delta Multichoice Universal valve such as the R10000-UNBX is dependent on the trim being used to determine the flow rate. For example, a 13/14 series trim used with this valve should provide approximately 4.9gpm at 40PSI whereas a 17 series would produce 5.0gpm at 40PSI. A T17T thermostatic trim kit will provide the highest rate at 7.0gpm at 40Psi or up to 9.8gpm at 80PSI. If the installation will not include a tub spout, a high flow valve such as R10000-UNBXHF will increase this rate further. Please contact us directly if you have questions or need further assistance.
Best regards, Edward

Universal shower valve. Water will not get very hot even when the limiter is not in place and full how water is on. I increased the temperature on the water heater to no avail. Is there a limiter on the valve body itself that can be adjusted?
Hi, Floyd!
Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta faucet. The valve body, R10000-UNBX, does not have a limit stop for temperature control. The only limit stop is on the valve cartridge assembly. To adjust the rotational limit stop on your valve cartridge assembly, here is a how-to video on how to adjust this:
