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

Poor customer service and cartridge.
I redid the three showers in our house less than two years ago. I had Delta products installed by a contractor because I thought the quality was superior and they are suposed to have excellent customer service. Now one of the facets is leaking. I couldn't be more disapointed in my call to their customer support group. She didn't even ask me about the facet or the replacement part. She simply said, "we don't replace cartridges". I'm sad that Delta didn't stand behind their product and provided such curt customer support. She didn't even offer to have me purchase a new cartridge from them.

Leaked after 2 years
Horrible and plastic. Our contractor installed the Delta R1000 that comes with this cartridge in 2024. We redid the shower so we could get a wheelchair into it. It started leaking in May 2025 and I don’t have a receipt. Lucky me, get to spend $100 to replace a lifetime warranty. Don’t recommend due to cheap materials and poor service

I switched to Delta because Moen cartridges kept going bad after less than a year.
Now every single one of the Delta showers (4) I put in my houses are leaking after only a year or two.
Terrible quality. Delta should be ashamed.

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.

Q&A
hot cold directions reversed
installed this cartridge and hot and cold direction are reversed. removed it and reinstalled in opposite direction, same result. Should reversing it correct this issue?
Thanks
Hi GM NJ, Thank you for your question. The RP46074 cartridge will have "Hot Side"on the second tier down on the gray plastic portion. As long as that is pointed to your hot supply side the cartridge and handle will function normally. The handle when installed correctly on the faucet will travel from the 3 o-clock (off) to the 12 o-clock position (fully on). The handles does fit on 2 ways, just make sure it is oriented correctly.
Thanks,
Dave

I don't know which replacement part I should order. It looks like rp19804 or rp46074, and the color is grey/off white. It's from the builder in 2015.
Hi, alex! Thank you for your question. The Delta part number RP46074 would be for a valve that was installed after 2006. The Delta RP198904 is for a valve that was installed before 2006.

What is the maximum flow rate for the tub filler RP46074 cartridge used in the T4759-FL?
Hi,
We thank you for your question. The floor mount tub filler flows at a rate of 6-9 gallons per minute with the pressure balanced cartridge RP46074 and 10-12 GPM using the high flow RP73598 cartridge depending on your household water pressure.
Best regards,
Brandis

I installed a new shower faucet RP46074 but the water pressure is minimal, and very low coming out of the shower head.
When I remove the cartridge and turn on the main valve, there is plenty of pressure, but with the cartridge installed, pressure is substantially reduced. I bought a spare cartridge and installed it with the same results. How can I increase the output flow?
Are there any mods or alternate cartridges that will yield more flow?
Hi Kim, Thank you for your question. At 60psi your RP46074 cartridge should provide approximately 6 gallons of water per minute. The showerhead itself is what limits the water flow. You will want to remove the showerhead and make sure there is no debris restricting the flow in the head. Also check the flow without the showerhead in place to help flush the line. Our showerheads have flowrates of 1.5 to 2.5 gallons per minute depending on the trim.
Thanks,
Dave

Trim compatibility
Will the trim only (the escutcheon, single lever, trim sleeve, etc) from the B112900 Foundations 1-Handle Shower faucet fit on a RP46074 cartridge installed in a R10000-UNBX valve? The B112900 trim looks extremely similar to the Monitor 13 T13220 kit (P19809 escutcheon and H79 handle kit), which is compatible with the RP46074 cartridge. Thanks.
Hi Sd, Thank you for your question. Unfortunately the B112900 and B114900 Foundation faucets are the only tub/shower trims we offer that will not fit the R10000-UNBX rough. Any current T13/T14 series trims will fit the RP46074 cartridge and rough.
Thanks,

what are repair instructions for part 46074?
Thank you for your question, Jimmy! The Maintenance and Installation manual below will detail how to replace a cartridge that is no longer working properly. For a drip when off, the RP4993 seats and springs can be changed instead by twisting the upper portion of the cartridge assembly cap off. Please be sure the water is completely shut off to the unit, room or home first. Please contact us directly if you have questions or need further assistance.

Follow up question. What about the large o-ring that surrounds the value?
Hello Theman,
Thank you for your inquiry! The larger o-ring around the body of the cap of the RP46074 cartridge assembly, is apart of it design, it is not sold as a separate part. You would need to replace the full cartridge assembly.

Is the internal moving part of the balancing brass or copper
I am in an area of the world were brass does hold up. The properties in the water adhere to the metal making any moving parts non- functional. We currently have Symmons in place and replace the spindle assembly every 45 to 60 days. We are now looking at your product as a replacements.
Thank you for your question. Delta Faucet model # RP46074 is composed of non-metallic materials and stainless steel. There are no brass components in this part.
If you are interested in purchasing these parts, Delta Faucet has a sales office in Dubai or you may contact our home office in the states.

Hot water on right
Cold water on left Thank you
Hi moses castillo,
Thank you for your question. This cartridge is pressure balanced, which balances to the flow rate to the lower pressure between the hot and cold supply. You will need both the hot and cold supplies turned on for water to flow.

How to determine the correct cartridge for the valve body
I'm shopping for shower valve, but none of them states which cartridge series will fit in the specification. Is there a search feature somewhere that I can input the valve model number and have it tell me the suitable cartridge?
Dear Scv,
Thank you for your question. The Delta MultiChoice Universal Rough In valve R10000-UNBX is the valve assembly for all of our Delta Shower and Bath tub/Shower Trim kits. The Delta Trim Kits come with their cartridge assembly to go in the valve.

How to properly adjust pressure in the Delta 13/14 Series Faucet
A year ago I had a Delta 13/14 Series Faucet system installed in my shower and the pressure has been good. Last night the pressure seemed to double for no reason. Temp is still ok. We have had no recent disruptions in service or issues with our plumbing system.
Hi billjingo, Thank you for your question. The RP46074 cartridge controls temperature only, there is no pressure adjustment available on this model. The increase in pressure could be caused by debris that was in the lines or cartridge working its way loose and out of the faucet.
Thanks,
Dave

I have a model from 2000- did the distance change on the water inlets?
I purchased a cartridge from Lowes that stated Model 13 /14 but the inlets ( white section) are more narrow then the original one.
I just received this replacement and the inlets were about 1/2" too long. I needed the RP19804 instead.

Thank you for you question, Anthony! Most Delta shower trims will include the series number on the escutcheon plate just under the handle. You can also remove the handle to see if the your model uses the older RP19804 cartridge which has a white cap or the current Multichoice gray cartridge RP46074. You may also have a 600 or 1600 series depending on the date it was installed. Please feel free to contact us directly if you have questions or need further assistance identifying your model.
