PRODUCT FEATURES
The TempAssure® thermostatic cartridge allow precise control of your shower temperature. The cartridge functions like a thermostat to precisely measure and control the water temperature. All Delta® tub and shower faucets are engineered to keep the water temperature within a safe ±3.6° F (±1.7° C)*. This technology makes sure your family doesn’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. Delta thermostatic tub and shower faucets are built with TempAssure® valves. The valve features an adjustable handle limit stop that, when properly set, helps ensure the handle cannot be turned to a position that is too hot for comfort.
*Requires inlet water temperature be set correctly. May require seasonal adjustments.
- TempAssure® dual-function thermostatic cartridge.
- Use with MultiChoice® 17T Series trim produced after March 2016
- Allows for separate volume and temperature control
- ASSE certified (ASSE 1016)

Ridiculous price
The price on this item is ridiculous and from the reviews I have read, this cartridge needs to be replaced frequently.

PRODUCTS THAT FAIL, HORRIBLE CUSTOMER SERVICE
DO NOT PURCHASE THIS OR ANY ITEM THAT CONTAINS THIS PIECE. Lost hot water and water pressure less than three years after installing in a new build home. Took multiple phone calls (and very long wait times) to get the item replaced under warranty. Except I still haven't received the replacement, the website shows that the status is shipped but has no tracking information, and a phone customer service rep has told me that is incorrect and it has not shipped. I was told I could choose to purchase the item on my own (nearly $500), and then "request" reimbursement but I would not hear for 30-60 days whether it was approved, and there is no way to receive advanced approval or a guarantee of this in writing. Shower is completely unusable. Will never buy from this company again.

ABSOLUTE JUNK
I have replaced this valve five times in as many years. Most recently, I purchased one in March 2025, and it failed in December 2025 (barely nine months later). The failure mode is identical every time: it works well for the first few months, then gradually delivers less and less hot water.
I am confident the issue is the cartridge. If I starve the valve by turning on cold water at my tub (which is upstream), I immediately get full hot water again because there is no cold water available to mix. Each time I replace the cartridge, full hot water is restored.
I was able to get one cartridge replaced under warranty about four years ago. Every other replacement has been out of pocket. I have attempted to obtain warranty replacements for the others, but I am consistently given the runaround, and the warranty is never honored.
Compounding the issue, the shower handle assembly is clearly not designed to be disassembled as many times as required to address this problem. On one occasion, the handle set screw seized and had to be drilled out, then re-drilled and re-tapped for a larger size (which has since begun stripping again). On another occasion, the temperature limit cap (located on the tip of the cartridge) could not be removed and also had to be drilled out.
This shower cartridge has been an absolute nightmare. The amount of time, effort, and money I have wasted is completely unreasonable.
Delta should be ashamed to sell this product. It is clearly a flawed design, and there appears to be no viable alternative within their lineup. In hindsight, it would have been cheaper to open the wall and replace the valve with a different brand rather than continue replacing cartridges. At this point, I will have to absorb that cost as well.

Expensive Piece of Junk
I’m now replacing this cartridge a second time in a year. I’ve never had so many issues with a shower cartridge before. It works great at first but after several months the hot water slows until it’s just a trickle. I’ve taken it apart as much as I could and there isn’t really any visible buildup. I should not have to go through three cartridges in 4 years, especially considering how expensive this part is. At this point I’m just considering replacing the entire fixture with a different brand since in the long run it will be more affordable. Delta needs to make a more reliable part.

Great serviceable product
Its a good cartridge that obviously non-mechanicly inclined people just dont understand. I bought this new for a bathroom remodel back in 2018. Here its is 2025 and the hot side quit producing. All you have to do is pull the cartridge, disassemble, and clean the screens off. That's it, simple as that. Not saying the cartridge can never go bad, but its a very simple design that is easily serviceable. Most cartridges are a once and done. At least you can take this one apart and clean. Cleaned the screens, reassembled, and working like new again.

Q&A
I have a DSS Vero 1701SS shower system installed in 2015. Is this cartridge compatible with it? The current cartridge has 90150501 on its sticker and looks very similar, but not exactly the same. Thanks

Thank you for your question.
The RP47201 is compatible with our used with MultiChoice® 17T Series trim produced after March 2016.

I have an existing shower only valve that uses this cartridge. I would like to replace the trim. Can you advise which Delta model would fit? On my existing trim, it says Multichoice 17T/18T Series. But I am not finding a lot of choices for replacement
Hello Jack,
Thank you for your question. We are happy to help!
Because you have a Delta Faucet MultiChoice R10000 valve rough, you can install any valve trim that is T13/T14, T17, or T17T series. Any 17T trim would use the same thermostatic cartridge. But if you would prefer a pressure balanced cartridge, the cartridges from a T14 or T17 trim kit would also fit your valve.

I just installed a Delta Thermostatic Universal Cartridge P/N RP 47201 (same as the one removed) and when I turned on the water ,I only had cold water. Moving the water temperature lever did not help. Is there an adjustment on cartridge?
Hello!
You may need to uninstall the cartridge, flip it 180 degrees and reinstall. When installed upside down temperature issues like this can occur. Please reach out for further assistance if needed!

Can I put this cartridge in my old rough in? Can I upgrade my existing Delta valve to this cartridge? What extra trim piece would I need
Hi PATRICK,
Thank you for your question about the Delta Faucet RP47201.
This thermostatic cartridge can be used with a MultiChoice valve rough. If you have a MultiChoice valve rough, our 17T series trim kits include this cartridge and can be used with the valve.

I have a model T17T030-NN valve assembly, installed around 2008. Water is leaking from the valve body. Is RP47201 the correct replacement cartridge? The specs for this cartridge say after a date in 2016.
Will the multi choice 17T work in my existing rough ? It is a builders grade single handle no choice between temperature and pressure
Hi Donald,
Thank you for your question about the Delta Faucet model RP47201.
I recommend identifying if the cartridge in the current faucet would indicate a MultiChoice valve. A 17T series trim kit would need a MultiChoice R10000 series valve.
A 13/14 series MultiChoice faucet without volume control would use cartridge RP46074. This can be replaced with a 17T RP47201 in the same valve.
If the faucet without volume control is not MultiChoice and installed after 2006, it would use the RP70538. If installed before 2006, the cartridge may be RP19804. The valve used by these two cartridges would need to be replaced to use a 17T trim.
Please contact us directly if you have any additional questions!

I installed this cartridge along with my MultiChoice Valve Trim T17T038. But for some reason the water is only either hot or cold. It does not seem to mix warm water. The cartridge is new that came with the valve trim.
Hello JakeFromStFarm,
Thank you for your question! I am happy to help you!
If the Delta cartridge RP47201 is put in upside down it can cause the issue you are experiencing, I would like to have you flip the cartridge in the shower. There is also an H and C marking on the black plastic rim of the cartridge which can help to make sure its installed correctly.
Please contact us back for any further questions.

Hello, I have a 17/17T assembly I installed 10 years ago that seems to restrict the hot water flow unless its all the to hot and even then only for a short time. I'll have hot water at the sink but not at the shower. Cartridge going bad?
Hello Dave,
Thank you for your question. I apologize for any difficulty finding this information. We are happy to help!
I am sorry to hear your Delta Faucet shower has restricted water flow. We are happy to help. This may be caused by clogged screens in the thermostatic cartridge. To clean the hot and cold screens, please see the instructions on page 8 of the manual:

Can this cartridge be used with the Vesna 1400 series tub and shower kit to replace the pressure monitoring cartridge?
Hi Sdw1107,
Thanks so much for contacting Delta Faucet Company!
The RP47201 can be used, if the rough valve installed in the wall after 2006. The R10000 would be our universal rough, and the trim would need changed as well.

I presently have a volume / temperature Delta shower control trim. Is it possible to change to a series 17T control trim by replacing the existing RP46463 cartridge with an RP47201 cartridge into the existing rough-in housing?
Hello Chavo,
Thank you for your question! We will be happy to help you today. It should be an easy swap as both trims use a MultiChoice R10000 valve body.

My plumber said this valve may be responsible for hot water not getting to other places in the house and wants me to replace it, can that be true?
Hi Lancers13,
Thank you for your question about the Delta Faucet RP47201.
This thermostatic cartridge controls the temperature of the shower, but it cannot affect the temperature of other faucets. Hot and cold supplies are mixed in the cartridge and the output goes to the tub/shower only.
If the shower temperature is too low, the rotational limit stop can be adjusted.

Hello bobbyk,
Thank you for your question. We are happy to help!

If I bought a Delta 17 trim and wanted to upgrade to a Delta 17t cartridge in the future could I simply swap out the cartridge and keep the trim?
Hi Mpaul109,
Thank you for your question about the Delta Faucet RP47201.
To upgrade, you would need a 17T series trim, not only the cartridge. The 17T and 17 cartridges are not interchangeable in the same trim. 17T and 17 series cartridges/trims do fit the same valve rough.
Please reach out with any additional questions!

I need replacement O-rings for this cartridge. All 3. I found O-rings that should work for the two smaller ones, but I can't find a large O-ring. I'm not referring to the trim sleeve O-ring, but the O-ring that actually stops the cartridge from leaking.
