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.
Comes with all Delta pressure balance tub and shower faucets.
*Requires inlet water temperature be set correctly. May require seasonal adjustments.
- Monitor® single-function pressure balance cartridge
- Use with Monitor® 1300/1400 Series tub & showers produced before March 2006
- Allows for temperature control
- Integrated rotational limit stop

Miserable quality, expensive paperweight
They don't last. We have two showers on opposite sides of the same wall running the same water. In shower #1, the cartridge is as old as anyone can remember. In shower #2, we replaced the cartridge a year ago. $200 contract labor plus the cost of the cartridge. It lasted 6 months and started its ever-worsening leak when turned to the off position. $200 more plus the cost of another cartridge. The new one just suffered the same failure as the last two, and had to be replaced again. Another $200 labor, another new cartridge cost.
We're down almost $1,000 this year alone on these defective Delta cartridges. I might as well buy the knockoffs that cost a quarter of what these cost if I'm going to have to have them replaced every 6 months.

not enough hot water
new RP19804 cartridge installed but water just gets warm not hot enough and was not an issue prior to changing and changed due to minor drip. Other facets in the room are normal temp for hot water. What can be done?

Nothing Better Than OEM
Buying directly from Delta rubber stamps OEM components that are built to last. I've learned my lesson about the risk of selecting after market items or those that are advertised as compatible with OEM parts. If you're a DIY guy, especially when dealing with plumbing repairs, my advice is to buy OEM and enjoy significant savings on plumbers fees when the job is complete. More often than expected, 50-75% savings on a part can translate into the frustration of having to repeat the repair and do without for a longer duration until the OEM part is delivered. Being greedy has its unfortunate consequences, so trust Delta over third party sources!

Is this cartridge a temp control cartridge?
Hi dls1,
Thank you for contacting Delta Faucet Company! Please accept our sincere apology for the inconvenience you are experiencing. Here is what we can do to resolve your issue for you.
Our Delta Faucet Cartridge Assembly - 1300 / 1400 Series (04/2006 And Earlier) MODEL#: RP19804 is manufactured for our 1300/1400 series trim kits and does not determine temperature. The RP19804 is a pressure balanced cartridge and with new installations we recommend adjusting the RLS to get hotter water if needed.
I have attached a link to show how to adjust the RLS on our Delta shower cartridges. This will provide the option of hotter water, also we recommend making sure the water heater temperature is set to 120 or lower.

Hello, I just replaced my old cartridge with a RP19804 cartridge. I had to pull the new cartridge and rotate it 180 degrees to get the hot water correct. However, then the cartridge dripped. Are there seats & springs inside the cartridge?

My cartridge/delta shower was installed in 1998. Your picture of the referenced part Nr in one of your videos does not look like my cartridge. My cartridge has a stop notch at the top, whereas the one pictured does not. Will it still work for me?
Hi Bob12345, thank you for contacting Delta Faucet Company!
Yes, we have updated our cartridges over the years to meet plumbing specifications. RP19804 new rotational limit stop is now a plastic white part at the tip of the cartridge, pull it towards you and rotate counterclockwise for hot and clockwise for cold. Please note every notch can range from 4-16 degrees Fahrenheit.

I had to cut handle due to corrosion and need a new one. It's for product RP19804. Replacement used was Jones and Stephens C25447. Do you have some handle options that will fit? Thanks
Hello!
Thank you for contacting Delta Faucet Company!
Our RP19804 is the older 1400 series cartridge. To find a handle will be easy! You can use any of our current 1400 series handles, aside from our integrated and our Foundations collection. Please note if you decide to update the entire trim, the cartridge is included with the trim kit but the new trim kits include the new cartridge that is not compatible with the older valve.
We appreciate your inquiry. Please reach out directly if you have further questions!

Delta RP19804 picture shows a white top with a blue bottom. The part I am replacing shows a white top with a off white bottom, are they the same?
Hi Bob D,
Thank you for your question about the Delta Faucet RP19804.
A similar cartridge to the RP19804 is the RP46074. RP19804 typically has a white top and RP46074 typically has a gray top.
The difference between the cartridges is the shape of the legs. RP46074 has longer legs and RP19804 has shorter legs.
Please reach out with any additional questions!

My house was built in 2008 series 1400 is the cartridge RP19804 fits my shower faucet?
My shower control is about 18 years old. Would this be the correct part. I have a very slow drip at the shower head that drips that doesn't stop.
Hello Kris,
Thank you for your question about the Delta Faucet RP19804 Cartridge Assembly. I apologize that the shower is dripping. I know that can be frustrating. We are happy to help!
Yes, If your shower was installed before 2006 and the single handle is at the 3 o'clock position while off, the faucet would be a 1300/1400 series that uses this cartridge.
Recommended maintenance for a drip would be to clean and flush the valve, clean the cartridge, replace the RP4993 seats and springs in the legs of the cartridge, and check the condition of the o-rings on the legs of the cartridge RP14414.
Please reach out at customerservice@deltafaucet.com or 1-800-345-DELTA if you have any questions or need additional assistance. Thank you for being a loyal Delta Faucet customer.
