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
When was the R10000-UNBX introduced?
We're having our shower redone. We're also upgrading an old 14 series (Windemere I believe) to a newer Lahara. We have the wall open and the rough-in valve "looks" like it is the right one. My current one is circa 2000. Do you think the new Lahara will work with a rough-in valve this old? If we want to swap it out, now is the time to do it before the durock and tile go back on the wall.
Hi jreagan,
Thank you for your question. MultiChoice valves such as the R10000-UNBX began shipping in September of 2006. If you have a 1400 series unit made prior to this date, any current 14 series trim kit will work with the existing rough-in valve with the original cartridge rather, or RP19804, than the cartridge that comes with the kit.
Best regards,
Jon

valve was installed by a licensed plumber, but when you turn on the water goes from hot to cold vs. cold to hot. what is causing this - purchased new
This delta mixing valve replaced a Moen mixing valve. They both turn counter clock wise from cold to hot. Is this problem caused by a faulty cartridge?
Thank you for your question.
If you are getting reversed water flow from hot and cold, you will need to remove the cartridge assembly and rotate it 180 degrees before reinstalling it back into the valve. This will correct the reversed water flow you are having.
Best regards, Edward

Is the plaster guard removable -?
If the plasterguard were removed it would appear that the opening in the finished wall could be a much smaller hole - easier to drill with a hole saw in the existing tiled wall.
But is the plaster guard necessary to mount the escutcheon to or is it just to guide the install depth ?
Thank you for your question! The plastergaurd can be removed if the valve is installed on a stringer. It is designed as a guide for measuring the hole and the depth of the valve. If you choose not to use the plastergaurd as a guide to cut the hole, please make sure that the hole is large enough to access the screw holes.
Thanks,
Jon

What rough ins do I need?
I'm installing the following products and am wondering what rough ins I require.
T14453 (tub spout, shower head
57530 hand held shower
Store supplied a T11853 diverter as well as 1 R11000 rough in.
do i need another rough in to install the T14453 first and then run copper up to the R11000 to run the shower and handheld?
Hi Yxetower,
Thank you for your question. To make your shower system function properly, we recommend using Delta Faucet model # R10000-UNBX rough-in valve. You will also need a supply elbow for your handheld shower. We recommend model # 50570.
Thanks.

Does the R10000-UNWS have reduced flow compared to R10000-UNBX?
Hi, Jeff!
Thank you for your question. The Delta MultiChoice Universal R10000-UNWS Rough Valve Body will not have a reduced flow compared to the Delta MultiChoice Universal R10000-UNBX Rough Valve Body.

Is there a way to adjust the temperature inside of the valve? When I move the lever all the way to hot it is still only warm. My hot water works perfectly everywhere else but just not this valve.
Thank you for your question, Laythe! The R10000 MultiChoice Universal valves do not control temperature as it is only a mixing valve. Your series may have a rotational limit stop that does come preset in the neutral or luke-warm position. This should be set at the time of installation and instructions on adjusting this setting can be found in your Maintenance and Installation guide. Please contact us directly if you need further assistance with this adjustment.
Best regards, Edward

Selecting valve for Trinsic 17 shower, UN or UNBX or UNWS
What are the differences between UN and UNBX valves? Also considering UNWS and possible advantage of stops.
Hi Chuck, Thank you for your question. There is no difference between the R10000-UN and R10000-UNBX. The R10000-UN is sold in case quantities of 12 pieces only. The R10000-UNBX can be purchased individually. The advantage of using the R10000-UNWS is that if you need to work on or service the tub/shower faucet you will be able to shut off the water supply at the faucet and not have to shut off the water to the rest of the house.
Thanks,
Dave

model number
I bought a R10000UNFER some years ago and would like another of the same but don't find that number now. What is the equivalent model?
Thank you for your question. Delta Faucet model # R10000-UNBX is our multi-choice valve that can be used with any application like copper, iron or PEX pipe. We do not have a model number that is R10000-UNFER.

I have a R10000-UNBX valve and was wondering if it is pressure balanced or anti-scald.
Hi Bill, Thank you for your question. The cartridge actually comes with whatever trim you select. The 13/14 series features a single function pressure balanced cartridge, the 17 series has a dual function pressure balanced cartridge, and the 17T series has a thermostatic cartridge. All will offer scald guard protection.
Thanks,
Dave

R10000-UNWS Supply Pipe Sizing
I purchased a R10000-UNWS for my shower along with a rainhead and handheld wand. The valve body appears to come with 3/4 in fittings but my house piping is 1/2 inch copper pipe. Is is OK to use an adapter from 1/2 to 3/4 into the hot/cold water suply without adversly affecting the performance. My water pressure runs between 60-70 psi. If not, do you have models with a 1/2 in fitting?
Thanks in advance
Dan
Hi Dan,
Thank you for your question! This valve has 1/2" NPT male threads with 1/2" female sweat supply fittings. Smooth 1/2" copper pipes can be soldered directly into the valve.
Thanks,
Jon

Can the hot/cold water supply lines be connected at 90 degrees into the sides of this valve, or do they need a tee connection with a hammer arrester above?
Hi, Thank you for contacting us.
We apologize for any inconvenience. We are more than happy to help you.
The R10000 valve water supply lines can be installed per the installer.
Please contact us at 1-800-345-3358 if you have any further concerns. We are open Monday through Friday 7:00 AM to 7:00 PM central time, and 8:00 AM to 5:00 PM on Saturday.

Hi, I bought this rough in valve to use with T14259-LHD, and then decided I wanted a handheld shower 55085. Are all of these compatible? Will I be able to use the shower head and handheld separately? If so, how?
Thank you for your question, Belle28! Model T14259-LHD is compatible and can be used with a hand shower if you use a shower arm diverter to switch between the two. Below is a link to some Delta Shower Arm Diverter options.

How do I find trim kits for this valve?
Thank you for your question. Delta model #R10000-UNWS is our Multichoice Universal rough. This will work with an array of tub/shower trims that have a single, dual, or dual thermostatic cartridge. Throughout our website, we recommend searching for tub/shower units that begin with T13*** or T14*** for the single; T17*** for the dual, or T17T*** for the thermostatic trim options. The cartridge will ship with the trim package selected.

I would like to mount the valve higher than 18" from the spout. Can this be done? if the pipe is upsized does that make a difference? thanks
Hi, Art.
Thank you for your question. Unfortunately, the Delta MultiChoice Universal R10000-UNBX Rough In Valve Body and tub spout must be installed between 8"-18" to prevent Shower Rise. A bigger pipe will not make a difference. I do apologize for any inconvenience this may cause.

Can use this valve for Tub Only?
What must I do to use this valve for just a TUB...No Shower!
Hi Eric,
Thank you for your question. Delta Faucet model # R10000-UNWS can be used with a tub only trim. You will need to plug the top port which is used for the showerhead.
Thanks.

I want to replace my existing shower.
I am looking at the shower / trim T17278 and separate slide bar handshower 57014. I want to be able to switch between the showerhead and handshower at the on / off control. I want to be able to have one or the other or both on at the same time .... Am I looking at the right products? What valve do I need to make this work?
Thanks
you would want a R10000UNBX valve for the shower trim and also a R1000 transfer valve. one is a pressure balance valve and the other is a transfer valve. With a transfer valve you cannot have "shared" functions but you can have one or the other functions. best of luck.

Is this a temp balancing valve?
Will it prevent burns if someone flushes toilet?
Hi, DIY Gal!
Thank you for your question. The R10000-UNBX is the valve body that holds the valve cartridge in for your shower trim. All valve cartridges that can be used with this R10000-UNBX rough valve are pressure balanced or thermostatic so that you will not get scalded when using other plumbing in your home.

Rosanna

Hi, Benjamin!
Thank you for your question. The Delta TempAssure T17T459-H2O Tub and Shower Faucet, MultiChoice Universal R10000-UNWS Rough Valve Body, Delta T11759 Diverter Trim, and the R11000 Diverter Valve Body all work together to complete a custom shower.

Do i need a in-wall diverter?
I have a Multichoice R10000 rough in kit and a multichoice T14059-rb monitor 1400 diverter trim valve.
I am hooking up a shower head and a handheld shower head on a bar w/ a supply elbow and need to divert one to the other.(there will not be a tub spout)
Im not sure if I bought the right thing. Do I need a in-wall diverter? I cant put a in-line by the shower head because the person is handi-capped and will not be able to reach high.
Thanks
Hi E&A Tile, Thank you for your question. You will want to plumb in a diveter. The R11000 diverter rough and the matching T11859-RB 3 setting diverter trim will allow you to use each showerhead individually or both at the same time.
Thanks,
Dave

Rough-in Valve R10000-UNWS
I have R10000-UNWS Rough-in valve, and I am going to plug the tub spout port(buttom threaded male port), as there is no plan to install tub spout, and this is for T17294-SS-I only. Could you instruct me what kind of pipe/tube cap to use for plugging this port - dimension/size, material type, spec.
Thanks very much for your help.
Ken
Thank you for your question. Delta Faucet model # R10000-UNWS can have the tub port plugged if you are not using a tub spout. We do not supply the plugs. It is a 1/2" pipe and if you contact your local retailer or wholesaler, they should be able to supply you with the appropriate plug.

I ordered the R10000-UNBX for the shower, no tub.the tub is in another area. I RECEIVED R10000-UNBXT. IS THIS CORRECT TO USE?
Thank you for your question, Rose! I do apologize for any confusion about this rough in valve. Model R10000-UNBXT can be used as a shower only application. The tub spout nipple on the Delta R10000-UNBXT can be capped off with a 1/2" threaded brass cap.

How do I know which rough-in valve I need?
I'm remodeling our bathroom and going with the Delta windemere tub/shower trim kit with the RP46074 cartridge. It indicates that I need to go with the multi-choice R10000 rough-in valve, however there are several to choose from. How do I know which one I need?
Hi Liz, Thank you for your question. The R10000-UNBX is the most commonly used version of the rough. If you want to be able to shut the water off at the faucet when doing any repairs the R10000-UNWS will work for you as well.
Thanks,
Dave

Dear Cj,
Thank you for your question! The older 13/1400 series cartridge assembly RP19804 will not work/fit in the new Delta MultiChoice Universal Rough-In Valve R10000-UNBX. The correct cartridge RP46074, will come in the box with the trim kit, your choose for it.
