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.

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!

Q&A
Should you lube the o-rings on the new cartridge before installing? Also, should you lube the treads for the bonnet nut before installing?
What type of lube is recommended?
Hi Without Shower,
Thank you for your question. The o-rings and seals are pre-lubricated with silicone grease. We do not recommend to apply any extra lubrication.
Best regards,

Hello. I have an existing 1400 series shower valve. I wanted to update the face plate and handle, got a new Delta Showerhead/Plate and handle. Are the 1400 series and 13/14 multichoice cartridges interchangeable? The new handle won’t fit my old cartridge
Hi, James!
Thank you for your question. If you have an older Delta Monitor 1300/1400 Series Valve, any new trim kit that starts with T13 or T14 will work with the existing valve. The new trim will come with a new valve cartridge assembly. This new cartridge will not work in the existing valve. You will want to keep your same, white cartridge. If you do need to replace the cartridge, you will want to replace with a RP19804 cartridge. Here is a link to the valve trim kits and cartridge on our website:

what new or current shower trim kits are compatible with the RP19804 cartridge? Or is there a new cartridge that will fit and replace this one?
looking to modernize my kits with out tearing up my walls and plumbing by having to replace the mixer etc.
Hi Ed,
Thank you for your question! Any of our T13 or T14 series trim kits will work with the existing valve. However, you will need to use the RP19804 cartridge rather than the one that comes with the kit.

Basic question: how to tell if a product is 1300/1400 series?
Does 1300 series mean T13xxx-xx model numbers. And 1400 series means any model number like 14xxx-xx?
For example, do T14461-SS and T14459-SS both belongs to 1400 series and can work with this RP19804 cartridge?
Hi Ryan, Thank you for your question. The 1300/1400 series faucets were single handle pressure balanced tub/shower faucets sold prior to February 2006. The handle controls temperature only and turns counter-clockwise to turn on and clockwise to turn off. These faucets use our RP19804 cartridges. The model numbers would start with 13 or 14 and would be a complete faucet. The new single handle pressure balanced faucets that use our R10000 multichoice universal rough in produced after February 2006 are our 13/14 series. The trim is sold separately from the rough and models of the trim will start with T13 or T14.
These trims ship with our RP46074 cartridge. The T14461-SS and T14459-SS trims will both work on your older 1300/1400 series rough. However the new cartridge that ships with the trim will not fit your existing rough. You will have to continue to use your existing cartridge or order a new RP19804. One identifying feature between the 2 series is the top of the cartridge. The top of the RP19804 cartridge used in the 1300/1400 series will be white, the top of the RP46074 cartridge used in the 13/14 series will be gray.
Thanks,
Dave

I purchsed a new replacement cartridge for our Delta Monitor 1400 series. My problem is I can't get the old one out. I followed the instruction that came with the new cartridge new. Any help? Bob Fornaciari
Hello Bob,
Thank you for your question. We would recommend first removing the handle. Then. slide off the finished metal sleeve that covers the valve. Next, unscrew the bonnet nut. The bonnet nut is a smooth large brass ring that should unscrew by hand. If it will not unscrew by hand, then I would suggest using a 50/50 or stronger mixture of tap water and white vinegar. Soak a rag in the mixture and wrap the rag around the bonnet ring area. Use tongs if necessary. Leave the rag in place for 15 minutes or so. This should help dissolve the calcium build up, so that the bonnet ring will unscrew for you. Remove the rag and attempt to unscrew the bonnet ring or you can leave it on so that you do not scratch the bonnet ring with your strap wrench or channel locks. Make sure that the entire valve body does not start to rotate as you do this. Repeat if necessary up to 4 times, taking care to protect surfaces that may be damaged by vinegar. The white vinegar can stain porous stones like granite, limestone and marble.
Lastly, Do not pry the cartridge out of the body with a screwdriver. Re-install the handle on brass stem (H) and rotate counterclockwise while lifting the cartridge out of the two notches on the sides of the body.
Best regards,
Tanya

Can this valve use RP46463?
I have a pre-MultiChoice shower valve (installed around 1993). I have been using cartridge RP19804 but would like to use a 17 series trim now, including independent temperature and volume control. Can the old rough be used in any way with RP46463, or do I have to replace the rough with the newer MultiChoice valve in order to fully use the 17 series products?
Hi Rob,
We thank you for your question!
In March of "2006" we manufactured a universal valve body model R10000 that allows any of our current multi choice trims to interchange. If you have the universal valve you will be able to change your 13/1400 series with one control for volume and temperature to our 17 series that has separate volume and temperature control. However, since your unit was installed or manufactured prior to March of "2006" you have an older valve body and will not be able to change your trim to our dual control 17 series trim. You will only be able to use any current T13 or T14 series trim but will not be able to use the new universal valve cartridge that comes with the new trims. If you want to switch to the T17 series you will need to replace the valve body.
Best regards,
Brandis

My house was built in 1999. We are trying to replace out 1400 series with a 1700 series TRIM KIT. The cartridges are different.
The 1700 cartridge is too narrow where the water comes in.
This is a picture of the 1700 cartridge. The holes in the 1400are farther apart. We are trying not to have to replace the plumbing in the wall. Which cartridge will work will my 1400 series without a major plumbing job?
Hi, Db!
Thank you for your question. If you want to replace your 1400 series trim with a new T17 series trim, you will need to replace the whole valve body inside of your wall. If you do not wish do do that, we recommend using T13 or T14 series trim to replace your existing 1400 series trim. You will need to use the same RP19804 cartridge, not the new cartridge that comes with the T13/T14 series units.
Best Regards,
Rosanna

Is my series 1400 tub/shower faucet still under warranty? Faucet is dripping and will not shut off. I am the original owner of the home built in 1995
Replacing p/n RP19804 with new same part no. Upon wiggling out the old part, the lower half, the blue part, separate from the cartridge. It is now difficult to pull out that blue 1/2 part. Question, can I pull with force?
Hi Rich,
Thank you for contacting Delta Faucet Company. Please accept our sincere apology for the inconvenience you are experiencing by removing your cartridge. We are happy to assist.
We recommend putting the top half of the Delta Faucet Cartridge Assembly - 1300 / 1400 Series (04/2006 And Earlier) MODEL#: RP19804 back inside the valve. Twist it to connect it to the bottom half of the cartridge, and pull straight out of the valve. We do not recommend using a lot of force.
Thank you for being a loyal Delta Faucet customer. We look forward to continuing to serve you. Please feel free to contact us back for further assistance.

The shower I have showes “ASSE 1016 P Delta” on the brass nut that holds the cartridge in, will this part work to replace the old cartridge?
Hi Jewduhman, thank you for contacting Delta Faucet Company!
The new bonnet nut will fit the older 1400 series valves. To verify the cartridge you need, the RP19804 is pre-06 and is white on the top and blue on the bottom. Please note the cartridge has been updated and may look a little different than the older cartridge. Please reach out to us directly so we can further assist you with this matter.

My home was built in 1999, The part for making the water colder was different from what is shown. Will this still work? I could not get the cartridge out, but the plate on the outside said Series 1400 so I am assuming this is the only option?
I have a Delta 1400 series currently. Can I change to a different series and keep the rough valve. Will the new series cartridge fit in the older valve.
Hello PeaceFrog,
Thank you for your question on Delta Faucet RP19804 Cartridge Assembly - 1300 / 1400 Series, I would be more than happy to assist.
The RP19804 is used with our pre-2006 1400 series shower units. You can update to our current shower trims while still using the old cartridge and valve. In order to update, we recommend making sure the screw locations on your existing trim are at the 1 o'clock and 7 o'clock positions. Please note: a new cartridge will be included in the new trim kit but will not fit the old valve. We recommend using the pre-existing cartridge.
Thank you for being a loyal Delta customer. We look forward to better serving you in the future. Please contact us directly with any further questions.
Best Regards,

Does Cartridge Assembly - 1300 / 1400 Series (04/2006 And Earlier) have a flow restriction in it? My same shower head before replacing cartridge seems seems to have a weaker than before.
Hi Dave,
Thank you for contacting Delta Faucet Company. Please accept our sincere apology for the inconvenience you are experiencing locating this information. We will be happy to assist you.
It is possible that flushing the product could resolve this issue. To do this, turn off the water supplies, remove the cartridge, and turn the supplies back on for one minute.
Please make sure that you are getting good flow through both the hot and cold sides while flushing. You can also shake the cartridge back and forth to make sure the back half of the cartridge rattles. This means that the pressure-balancing spool is moving freely, as it should.

Can you adjust these to let more hot water through
Hi Shane,
Thanks so much for contacting Delta Faucet Company!
It sounds as though the rotational limit stop the Cartridge Assembly MODEL#: RP19804 may need adjusted. The rotational limit stop is used to limit the amount of hot water available such that, if set properly, the user will not be scalded if the handle accidentally is rotated all the way to “hot” when a person is showering or filling a tub. The first position allows the LEAST amount of hot water to mix with the cold water in the system. In the first position, the water will be the coldest possible when the handle is turned all the way to hot. As you move the rotational limit stop counterclockwise, you progressively add more and more hot water in the mix. The last position to the left will result in the greatest amount of hot water to the mix, and the greatest risk of scald injury if someone accidentally turns the valve handle all the way to the hot side while showering or filling a tub.
To adjust the temperature of the water coming out of the valve, pull the disc back to a position where it is possible to remove the rotational limit stop and readjust the teeth engagement position to the desired temperature. Clockwise will decrease the outlet temperature, counterclockwise will increase the outlet temperature. Temperature change per tooth (notch) could be 4° - 16°F based on inlet water conditions. Repeat as necessary. Push disc until fully seated.
If you would like installation help, you may contact our residential warranty line directly at 800-345-3358 (prompt 2, then 4). We also have how-to videos on our website and on our YouTube channel.

Do you have new shower faucets that use this cartridge/valve? In oil rubbed bronze? I don't want to rip into the wall but want to replace the shower faucet and head so would like a model that uses this cartridge.
Hello Janice!
Thank you for contacting us at Delta Faucet! I will be happy to help! Yes, if your rough-in valve was installed prior to April of 2006 you can install any newer 1400 or 1700 series Delta Faucet tub and shower trim kits without replacing the rough-in valve in the wall. Simply use the older RP19804 or RP32104 cartridge assemblies and not the new one included with the trim kit. Please contact us directly if further assistance is needed at this time.

Hi sengupta1,
Thank you for your question about the Delta Faucet RP19804.
A current 13 or 14 series trim includes a new, different cartridge, but the trim and handle should also fit this cartridge.
You can purchase Delta Faucet products from many local dealers and websites. I recommend our store locator.

If you are receiving the hot and cold water reversed, I would start by making sure the lines were plumbed correctly. The next step would be flipping the cartridge, this could cause the hot and cold to be reversed as well.
