PRODUCT FEATURES
Dual-function valve cartridge maintains a consistent water temperature from one shower to the next. 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*. 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® dual-function pressure balance cartridge
- Use with Monitor® 1700/1800 Series tub & showers produced before March 2007
- Allows for separate volume and temperature control
- Also works with 1500 Series produced after 1995

Bad Design Delta RP32104 from
Delta RP32104
I am using a licensed plumber and we are on my 4th RP32104 in 8 months. The first one we replaced to replace a gasket and that stopped the leak but after a month or so the handle spins around 360 and won't shut off the watter. I am not at all forceing or turning the handle with force because this cartridge cost $85 and I have purchased 4. I cannot change the housing without breaking tile and cuting the copper pipes but this is a bad design. Obviously Delta has changed the design because the old one lasted 17 years. This tiny square is the only thing that stops the handel from spinning around 360 and it keeps breaking. Can you help? This tiny

single handle for RP32104 cartridge

Replaced second RP32104, still have same issue, handle could be turn over and over freely. I think I need to change this handle (should be around 15 years). Which single handle should I purchase to match this RP32104, would you send me a link?

Happy I was able to find these!
My delta faucets failed after 20 years and I was relieved I was able to find the correct replacement cartridges. I now have to have them installed to find out if they solved the problem...

Excellent customer service
I purchased my delta faucets over 20 years ago and when they required repair, I was worried I was not going to be able to find parts. I was able to identify the part number and order through customer service, so I am relieved I don't have to buy new fixtures...I will say that I had a similar issue with another brand, and theirs was warrantied for life, so that replacement has no charge...Wish delta had the same policy-but I am happy to be able to find the correct part.

Delta shower faucet cartridge.
Installed easily after all water supply shut off. Works well. Stopped the dripping. Was a bit difficult to find the right cartridge- faucet installed many years ago and no model number visible, even after disassembly.

Delta RP32104 Cartridge Assembly - Monitor® 17 Series
Cartridge works great and included parts so I could use the 17 series shower parts on a 15 series control. Instructions were a little confusing and had to use a little trial and error to figure it out.

Q&A
Replacement cartridge for older model 1700 from 2002
Replacing older model 1724PB-LHP installed in 2002 which was in new construction. Found my receipt from 2002. Don't know which type of rough in valve was used as I did not see it when installed. Didn't intend to replace the rough in valve or cut into walls...only wanted to replace the exterior escutcheon, temp/pressure handles and the shower head and arm. I was advised that T17278-RB trim kit would work but not to use the cartridge with gray cap that came with it. Cartridge package is marked 46878 REV A 10/11/05. I would have to use my old cartridge. As far as I can tell it appears to have a white cap. Which one do I use so that I don't have any rehab work behind the wall. Or, can I continue to use the old cartridge as long as it works. I viewed video which includes instructions for 13/14 series and 1700 series and believe I need cartridge RP32104 with the white cap and longer tab at bottom for 1700 series shipped prior to 2006. Thank you
Hi Bea, Thank you for your question. The RP32104 is the correct cartridge to use with your 1700 series faucet from 2002. The T17278-RB trim will fit your existing faucet but the RP46463 cartridge that ships with the trim will not work with your existing rough in valve.
Thanks,
Dave

I have Delta Mulitchoice 13/14 series faucet the cartridge has gone bad, will a 1700 series cartridge work in this body?
Hi Dave, Thank you for your question. The RP46463 cartridge will fit the rough in valve body from your Delta mutichoice 13/14 series faucet. You will also need a 17 series valve only trim to make the faucet function properly. The 17 series cartridge will come with the new trim.
Thanks,
Dave

I have the Delta series 1700 that uses the cartridge 32104 . What are the other part numbers or letters that I need to complete the rest of the unit. It just seems that no one can answer me on this question. Please help thx
Thank you for your question, Raul! An original 1700 series Delta shower does use the RP32104 cartridge. This cartridge can be used with any of our current T17 trim kit options to complete your unit; however, please note that current trim kits will include a Multichoice 17 series cartridge that will not fit into the original 1700 series valve body and you must continue using the RP32104 cartridge.

My house was built in 1980 and I am sure this shower off'/on is the original. I can fix quite a few things but I am afraid if I turn off the water and the parts I need, need to be ordered, is there a way to close it back up until I get the new parts?????
Thank you for your question, KATHIE! RP32104 was not an available part at that time. Below the handle on the escutcheon plate, there may be a series number printed which will indicate the correct parts needed. All series and models can have the parts re-inserted in the event that they will need to be ordered. Please contact us directly if you need assistance finding the correct parts.

Can the RP32104 be replaced with a newer verion to change trim and handle?
Hi Mark, Thank you for your question!
If you have an older 1700 series tub/shower you will be able to upgrade the trim to one of the T17 series trim. However, you will not be able to use the new 17 series multi choice cartridge. You will need to use your old RP32104 valve cartridge.

I've used the rp32104 and I'm wondering what trim is compatible? Is it anything in the 17 series? Thanks!
Hi,
Thank you for your question. You can use any of the Delta tub and shower trim kits that start with a T17, except for the T17T series trim kits will interchange for you. Some model number examples are T17255 and T17278. The cartridges that come with the new trim kits will not fit your valve body, so you will need to reuse your existing RP32104 cartridge.

Brandis

Larger O-ring replacement for the RP32104 cartridge
I am looking for a replacement for the larger o-ring on the RP32104 cartridge with out having to replace the whole cartridge. Can someone proved me a model number to the o-ring or the specs for the large o-ring that search for a replacement. I would like to find the info on the o-ring so I do not have to turn the water off for a long period of time.
Hi GTMPuck,
Thank you for your question. Unfortunately, we do not offer the o-ring as a separate part, but you may be able to find a replacement locally. The outer o-ring is 1 9/16 x 1 ¾ x 3/32 & the Uniform Size is 129.

I just bought a new home that has a model 1700 or 17 tub and shower valve the water just dosn't stay hot enough on the second shower .
I have hot water everywhere else. is this just an adjustment or a bad valve?
Thank you for your question. I apologize that you are having an issue with your faucet. It is possible that your rotational limit stop needs to be adjusted to allow more hot water to flow through your valve. Included here are instructions for adjusting the limit stop. The directions are on page 9.
We also recommend making sure your hot water heater is set at around 120 degrees to get enough hot water to your shower.

I have an old Delta Monitor 1500 series tub and shower fixture that is leaking. I'm replacing the cartridge assembly with the RP32104 conversion kit.
Can I still use my current handle and trim?
I was not notified of that by a Delta rep. I am having major issues with getting the handle sleeve off of mine to get to the cartridge. I was told that the limit collar and that sleeve should slid right off. Granted I have calcium build up which I'm trying to take care of by spraying small amounts of "CLR" from a spray bottle occaisionly on the inside of it behind the temp. control handle/ring. Looks to me like there's a brass nut holding the sleeve on that's just in front of the screw on knurled chrome ring. I was told NOT to remove that nut. Looks like to me that that nut has to be removed to get that sleeve, that the volume lever screws into, in order to slide it off.

Will the rp32104 cartridge assembly replace a rp46463 cartridge assembly?
Hi, Terrence B!
Thank you for your question. The RP32104 will not replace the RP46463. If your Monitor 17 series trim kit was installed before 2006 and the cartridge is white, you will want to use RP32104. If your Monitor 17 series trim kit was installed after 2006 and the cartridge is gray, we recommend to use RP46463.

I have a Delta Moniter RP28595 shower and tub spout from 2003. Can I replace the trim with T17038 without changing the rough in?
Hello Oocd,
Thank you for your question, I would be happy to help you.
The older 1700 from 2003 can be updated to the T17038 without changing the rough valve. However you can not use the new cartridge, you would need the old cartridge RP32104.
Please contact us back for any further questions or concerns.

With regard to the Delta Monitor 1700 series, I encountered a (bonnet, brass collar) that refused to come off with either a strap wrench or channel locks. How can I remove this other than cutting with a dremel? Brass on brass fitting. Kroil or WD-40?
Hi Steve242,
Thanks for your question regarding RP32104! We recommend soaking with a 50/50 solution of white distilled vinegar and water. If that does not resolve the concern then we recommend cutting off.

I have a delta monitor shower faucet installed around 1999. The RP 32104 valve cartridge will replace old one I need to upgrade trim. Oiled bronze can’t find the right trim. Help
Hi Dave,
Thank you for your question! I am sorry this information was not readily available, and I am happy to help!
The RP32104 cartridge would be included with pre-MultiChoice 17 series shower trims. A current, MultiChoice 17 series trim can be used. The new cartridge will not fit the old valve, but the new trim kit will fit the original valve and RP32104 cartridge.
We don't currently carry 17 series shower trims in oil-rubbed bronze, but for example, the similar Venetian bronze finish would include model T17276-RB.

Can I use RP46463 instead of RP32104 FOR A DELTA FIXTURE INSTALLED PRIOR TO 2006? Would it work?
Hi lilredindy, thank you for contacting Delta Faucet Company!
No, the RP46463 and RP32104 are not interchangeable. The valve bodies are different. If you decide to upgrade your trim, you can use the trim just not the cartridge for older valves. The RP32104 will still need to be used in the older valve.

Hi, my shower uses a RP32104 cartridge. However, i am a bit confused on which replacement shower handles (trims) from the Delta 17 series to buy? Can i buy TempAssure or i am limited just to Motion?
Hi cazamoral,
Thank you for your question about the Delta Faucet RP32104.
A shower that uses this cartridge would be from before we introduced our MultiChoice valve.
A new 17 series trim should fit your valve and RP32104 cartridge, but not a 13, 14 or 17T series. The new cartridge included with the trim will not fit your valve.
Please reach out with any additional questions!

Hi Wagoner,

Hi Bre69,
Thanks so much for contacting Delta Faucet Company about RP32104!
Low flow is caused by a blockage or debris and would need to be flushed out. I have included a link below to the Help Center with the flushing instructions.
