Rated 5 out of 5 by from 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

Are there plugs available for the ports the service stops go in, I might not have the clearance for the stop stems for the cover plate to mount flush

Asked by: Rob H
Hello, Thank you for your question! Unfortunately we do not offer plugs for this. You may need to install a standard R10000-UN rough-in valve in its place. Please reach out with further questions! Best Regards, Tim Digital Communications Specialist

I need to order the proper fitting in order to install our delta faucet set. I cant figure out the difference between R10000-UNBX and R10000-UN. Also is there a three neck hook-up version?

Asked by: Casey
Hi, Casey! Thank you for your question. The Delta MultiChoice Universal rough valve bodies R10000-UNBX and R10000-UN are the same and have no differences. For a 3 neck hook-up, we recommend to add a diverter valve to the top port to be able to install additional shower units. Best Regards, Rosanna

Can I buy extra parts to upgrade the R10000-UNWS & T17253 to equal the T17T453?

I need to add a bathtub faucet and thermostatic cartridge. If I buy the RP53419SS faucet and the RP47201 thermostatic cartridge, will they work with the R10000-UNWS MultiChoice Rough and T17253 shower trim kit?
Asked by: jumperboy
Hi Jumperboy, Thank you for your question. While the tub spout would work, the thermostatic cartridge RP47201 would not work with the handles for the T17253. You would also need the RP62960 volume handle, RP62959 temperature knob, and RP50879 sleeve. http://www.deltafaucet.com/search/results.html?q=RP62960%2C+RP62959%2C+RP50879+ Thanks, Jon

I just installed a R10000unws tub/shower valve and have water coming out of the shower head and tub spout all the time?

Even though I have not pulled the shower knob up on the tub spout to activate the shower head, water is coming out of both the tub spout and shower head? Is there a direction (top or bottom) that you have to install the rough-in valve? Can you connect the tub spout or shower head up to either port?
Asked by: Joe
Hi Joe, We are sorry that you are experiencing a problem with your faucet. Most likely, you are experiencing "shower-rise" where the water can’t get out of the spout as fast as it flows through the valve. This causes the water to back up and come out the shower head. There can be one of several reasons for this: The valve could be upside down The length from the valve to the tub spout is outside of the 8" to 18" rule There is more than one 90-degree angle Something other than copper or galvanized pipe was used going to the spout The most common reason is that there is something restricting the water flow to the spout, e.g. solder or something lodged in the pipe. Something is impeding the flow of water to the spout and causing it to back up and go out the shower head. If this is the cause of shower-rise it is possible to remove the blockage by removing the tub spout; then, feeding a plumber’s snake or a speedometer cable up through the tub drop. The act of feeding it causes it to twirl and loosen the blockage. Be sure to flush the valve before reinstalling the tub spout. Be sure to check the tub spout itself for blockage. If none of these help, you may need to call a plumber. After the shower has been installed and the wall has been closed, there is little that can be done to remedy this situation yourself.

Can a R-1000RN rough-in valve be used with T17264 and RP77091 to add tub function

Hello, and thanks in advance for your help. Can a R-1000RN rough-in valve be used behind the Aslyn Monitor 17 T17264 trim kit (and using the RP77091 tub spout with diverter) to add a tub function? In other words, will the T17264's dual function cartridge properly insert and function in the R-10000RN rough-in valve? (Dual function = separate pressure control coupled with separate temperature control) Note: I don't think that it's an issue, but my install will also include a Delta R11000 3-function diverter after the R1000UN rough-in valve.
Asked by: garies
Dear Garies, Thank you for your question. The Delta MultiChoice Rough-In R10000-UNBX Valve is recommended to used T17264 (shower only) or the T17464 (tub/shower). The Delta Diverter R11000 Valve would be installed above it. Best Regards, Tanya

What is highest flow valve for filling a bathtub

What is the rate, gallons/minute of each Delta valve?
Asked by: Karen
Thank you for your question, Karen. The R10000-UNBX valve is the highest flow rate for the tub spout. The actual flow rate will depend on the water pressure in the home and the trim series that you install. Here are the flow rates from this valve (tub spout port) at 60 PSI: 14 Series: 6.0 GPM 17 Series: 6.2 GPM 17T Series: 7.8 GPM Best regards. Jon

Stops touch escutcheon

The valve stops stick out, blocking the escutcheon from screwing tight to the shower surround. Is there a shallow escutcheon plate or spacer that will fix this?
Asked by: Sky
Hi Sky, Thank you for your question! Please make sure that the plaster guard is flush (or up to 3/8" sub flush) with the finished wall. If the valve is out too far, you may turn the stops 3 turns in from the full open position without a noticeable reduction of flow. This will provide an additional 1/8” of clearance for the escutcheon. Best regards, Jon

In a 1-pc. fiberglass shower/tub , what size holes are needed for single lever faucet and tub spout ?

I am installing a 1755rb-716rb set and have to drill holes for valve and spout .
Asked by: Doug
Hi Doug, Thank you for your question! The hole for the valve should be cut to the size of the plaster guard which is 4" x 4". The hole for the size of the tub spout should be at least 1/2" for the pipe to fit through and no larger than the diameter of the tub spout, which is 3 1/8" on this model.

How accurate and how stable is the temperature control for this valve? If the user selects say, "100 degrees", (F), will it stay within a degree of that temperature? Thanks very much in advance for responding. Vancouver, BC

Asked by: Batcave
Thank you for your question, Batcave! The R10000-UNBX MultiChoice Universal valve does not control temperature but rather acts as a simple mixing valve. The pressure balanced 13/14/17 series cartridges as well as the T17T trims which include a TempAssure Thermostatic cartridge will keep the temperature between ±3° F (±1.6° C) at all times.

Could he need the temperature limit stop adjusted. Or could something else cause this
Asked by: lku1
Hi Iku1, Thank you for your question. The motion of the handle will run from 3 o-clock (off) to 12 o-clock (full on). The faucet is equipped with a rotational limit stop where you set how hot the water can get. I have attached a link to a video to show you how to make this adjustment.

I have a R100000-UNBX for a shower only installation. Can I just plug the tub outlet at the valve? Or do I need to exchange it for a UNBXH?

Asked by: Bill
Thank you for your question. Delta Faucet model R10000-UNBX can be used for a shower only application by pluggin the tub port. Model number R10000-UNBXHF is for shower only applications and if you would like higher flow from your valve. If you already have the R10000-UNBX, you can use it for a shower only application.

Is the model number printed on the valve somewhere?

My contractor has installed a Delta shower control valve as part of my bathroom remodel, but I can't tell which model it is, and want to know which shower/tub faucet combos I can consider. In particular, I like the Leland T14478-LHP H777 because I want a single porcelain lever. Which control valves will work with that faucet set? I've tried to look for a model number on the installed valve but don't know where to look or what distinguishes one from the other.
Asked by: Brian
Thank you for your question. The model number is not printed anywhere on our valves. If your contractor recently installed your Delta valve, it is a very good possibility that it is the R10000 series and the trim you are looking at will work just fine. In fact, with the R10000 series, you can change the trim as often as you like from the 1300/1400 to the 1700 series without going into the wall to change the valve.

R10000 Rough in Body w/Stops version. (17T)

On either side of the valve body, there are two (2) mechanical stem and nut assemblies. I assume, when turning the stem(s) clockwise, and the stem(s) bottom out, this will stop the flow of water completely. Conversely, if I turn the stem counter-clockwise the flow of water increases. How can I tell, without backing the stem out further than need be, will I get full flow? Instructions say " adjust stem clockwise to close, and counterclockwise to open". I'm not sure if I understand the purpose of these stops. Thanks
Asked by: Rick
Hi Rick, Thank you for your question. These stops are designed to turn the water off directly at the valve during installation or repairs. They should be left in the open position when the trim is installed, as the cartridge will be used to turn the water on and off. Best regards, Jon

Does cartridge RP46074 fit MultiChoice R10000-UNWS roughin?

I bought a R10000-UNWS Delta Rough in with stops, and a trim kit T13291-LHD. The box of the trim kit says it fits multichoice universal valve. However, the cartridge type that came with the trim kit is RP46074 that has "longer lower housing". The extra length will cause the handle to be more than 4 inches away from the finished wall (which looks ugly) if we follow the instructions to install it such that the plaster guard of the multichoice roughin is flush with the finished wall. It seems that the plaster guard should be about 1 inch subflush with the finished wall. My question: Did I get the wrong cartridge, or are the multichoice valve instructions obsolete, or have I misunderstood it? Any advice is appreciated!
Asked by: wei
Thank you for your question Wei! RP46074 is the correct cartridge for the Multichoice R10000-UNWS valve and the plasterguard should be flush or subflush 1/4" to the finished wall according to the installation manual. Distance from the stringer to the front of the plasterguard is 2-3/4" ± 1/4" (70 mm ± 6 mm). Distance from the stringer to the front of the bonnet is intended to be 3 7/8" (99 mm.) This is for reference only. If you need further assistance with this installation you can call us directly at 1-800-345-3358. Best regards, Edward
