PRODUCT FEATURES
Single-function valve cartridge controls the temperature at full output flow. Monitors water pressure to balance 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. The valve cartridge 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*. The handle limit stop's integrated design allows easy adjustment via pull and turn. Easily replaced seals make maintenance a snap.
This cartridge is included with tub and shower trim packages.
*Requires inlet water temperature be set correctly. May require seasonal adjustments.
- Monitor® single-function pressure balance cartridge
- Use with MultiChoice® 13/14 Series tub & showers produced after March 2006
- Allows for temperature control
- Integrated rotational limit stop

Bad customer service and fake warranty
Went for a 3-weeks vacation and came back to my shower leaking hot water. Walls in my shower was moldy and there are moisture behind the wall. Mitigation and redo cost more than $20k. Had to get a new RP46074 cartridge and called delta to see if they will honor their lifetime warranty but was denied! To get to the cartridge, the handle needed to be removed but the set-screw was seized and after several tries, the 1/8 hex key hole was rounded (robertson or star bit would be a better choice) so had to drill it out. Looking for a replacement set screw was a huge deal and an exceptional challenge - Lowes and Home Depot do not have them. 0 star!!

Terrible product. Class action should be filed.
I purchased a Delta OEM RP 46074 cartridge in November of 2025 and by December it was leaking from the shower head. Pulled it out, flushed the line, greased it and replaced it and in a few days it was leaking again from the shower head. It cost $65 and I bought it at Home Depot. I go online to research and I find this page with hundreds of people complaining about the same thing. I will never buy Delta again. I am a lawyer and I live in Pennsylvania. Cannot believe Delta would put such a terrible product on the market and do nothing at all to fix it. Does anyone at Delta care? Apparently not.

Would not recommend.
Starts to leak every 3 to 6 months. Replaced the O-rings and the cartridge twice. Last time I replaced the cartridge was November 2024. Correction, that is when I ordered it. Didn't arrive for 3 more weeks. It was a constant stream of water. I had to shut the water off to my shower after every use. The worst part is it's not even a good shower. The water pressure for the shower is weak.70% is plastic. Would not recommend.

Good faucet
Product came in damaged. Have tried to get a replacement for two weeks. It might show up today. Very poor customer service from Delta and FedEX. Will not use Delta again for parts.

Not what I hope for from Delta
I have bought several different brands of valve cartridges for this shower. They all leak. Do you have an upgrade or do I replace the whole thing and never buy delta again? I have used delta replacement. From Lowe's. Nothing working more than couple of months at the longest

Q&A
I have the classic Monitor 13 series shower assembly and my shower was installed in 1999 which cartridge do I use? RP46074 or RP19804? Thank you.
Hi Terry Kuntz, Thank you for your question!
You will need the RP19804 valve cartridge. The RP46074 valve cartridge is for 13/14 series tub/showers that were manufactured after March of " 2006".
Best regards,
Brandis

mine is 20 + years old. has the temp adjuster changed
I have a brass ring with teeth around the interior. A second piece that is nylon (?) that interfaces with the brass ring for adjusting temp. Is the #RP46074 replacing mine ?
Hi Roger,
Thank you for your question. 1400 series units manufactured prior to 2006 will use the RP19804 cartrdidge. You will find the redesigned rotational limit stop on this cartridge as well.

what valves do i buy to make two separate shower handles with each handle having volumn control. i have a shower head but no tub, and i do not like
the single valve in the center of the wall. do i use a solid brass wall mount, or do you have valves that can control each handle's water volume? Would a transfer valve work?
I sent an email earlier but I think I wrote my email address wrong....
Hi Ariana, Thank you for your question. The only volume control rough in valve and trims that we offer are available through our Brizo product line in the Sensori high flow shower system.

How can I make the water hotter with this cartridge, since it's not as hot as the old cartridge?
Thank you for your question, Stephen! Our cartridges include a Rotational Limit Stop that limits the amount of hot water allowed to mix into the valve and needs to be set at the time of installation. Information on adjusting this setting can be found on Step 3, Page 7 of the Maintenance and Installation manual below.

I need the best temperature regulating cartridge for a shower
I installed the Delta MultiChoice Universal Rough In valve R10000-UNBX during the rough-in of our bathroom and need to purchase a cartridge that will keep temperature as steady as possible. It is a single family dwelling without big pressure swings.
Which cartridge should I use to balance cost vs function?
Hi, DMS!
Thank you for your question. The valve cartridge comes with the new trim kit that you pick. This cartridge, RP46074, comes with our T14 series trim. This valve cartridge is pressure balanced.
Best Regards,
Rosanna

Can this cartridge be used with the T17097ss shower faucet?
Thank you for your question, John G! RP46074 is a 13/14 series MultiChoice cartridge. A current 17 series trim requires RP46463 instead.

Earlier today I ran across a page on your site that shows the different cartridges, but cannot find it no matter what! (Your website is to hard to navigate!) Can you please tell me exactly what the difference is between cartridge series 13 and 14
Thank you for your question, Randy! The 13 and 14 series have the same functionality, and take the same valve cartridges. The 13 series valve trims have a traditional design, and are all part of the Classic collection. The 14 series valve trims have a more contemporary design, and correspond to several Delta bathroom collection styles. The RP46074 cartridge is used with Delta 13 and 14 series valve trims, that have a valve body that was installed after 2006.
Best Regards, Benjamin

What is the maximun flow rate for the shower using a RP46074 cartridge at 60psi city water pressure.
Hi, jmcmil45!
Thank you for your question. The flow rate for the shower head will be determined by the shower head itself, not the valve body. We have shower heads that range from 1.5-2.5 gpm flow rate. Here is a link to our shower head and hand showers available:
