This part would only work if I installed it to work the with the opposite of the shower turn on direction, If it tried the other way it would not shut off the water.
When installed my turn the water on the revese direction to work. .

Older than my kids
Honestly, I've not installed this part yet, but Delta figured out which part from a photo, and sent me this replacement, for free, for my thirty-year-old shower. Can't comment on actually fixing the leak, but it's the correct part, with awesome customer service.

Problem Solver
Several months ago Delta sent me a new stem assembly at no charge that fixed my leaking Delta faucet that was over ten years old and I was ever so grateful. However the faucet was discontinued long ago and I feared that sometime in the future if it leaked again the repair part might no longer be available so I bought a spare.

Hope for the hopeless
Didn't think my odd, old tub faucet was repairable (one handle for temp, one for water flow) but this part and a few others and about an hour of time and it's working like new. Thanks for having diagrams and parts in stock!

I believe I have a Inovation 3530-24 bath vanity faucet. I need to replace the stem, but your diagram shows 3 different stems listed. There are no numbers on my existing stem. How do I know which stem to order?
Hello Bob70,
Thank you for your question. We are happy to help! The 3530-24 faucet uses the RP24096 stem unit. The RP1740 is the same and will work in the faucet. The difference is a plastic stem instead of a brass stem. RP25513 is RP24096 plus the RP24097 quarter turn stop. Please reach out directly if you have any questions or need additional assistance.
Best regards,
Bryan

What faucets does a RP1740 stem unit fit
Hi MaxW,
Thank you for your question about the Delta Faucet RP1740.
The RP1740 is a very common stem unit assembly, especially for two-handle faucets manufactured prior to 2015. This piece has a plastic stem. It is best used with handles that attach with a screw through the top, or using a retention screw for a lever handle. See here for more information:

I’ve got a Roman style tub faucet with round two tone handles which leak when turned on & faucet has a slow drip. Handles have a disk-like top you turn counterclockwise to remove, then there’s a screw in the middle. Can you tell me which parts I need?
Does this come in a brass version? My plastic ones have broken twice.
Hi Old Mildcat,
Thank you for your question regarding our Delta Faucet RP1740.
Unfortunately, the RP1740 is not available in brass. We do offer RP25513 for lever handles.

this part failed (hot side). I need that hot side replacement the Delta rp17040-C on the hot side makes the lever turn from the opposite side. Can you send me the specific rp1740-H ?and is there a lifetime warranty?
Hi Paul,
Thank you for reaching out to us with your inquiry. We apologize for any issues you are having with the product and are happy to assist.
This sounds like your stem unit needs to be rotated on that side 180 degrees with the 1/4 turn stop installed in the front.
We appreciate your business and look forward to continually serving you.

Is there a way to adjust the start stop radius on this stem assembly. My old stem assembly that I am replacing has a widget added in that does not fit this new assembly
Hi Shawn,
Thank you for contacting us at Delta Faucet! Please accept our sincere apology for the inconvenience you are experiencing. Here is what we can do to resolve your issue for you.
Unfortunately, there is no way of adjusting the rotational turn of this RP1740 stem unit. The RP25513 stem unit allows for the addition of the RP24097 quarter turn stop that will allow for the handle turn to range form 90 to 180 degrees. Please see the following link for more information.

Hi Craigie,
Thank you for your question about the Delta Faucet RP1740. A two handle Delta tub/shower faucet with knobs typically used this stem for hot and cold with RP4993 seats and springs. The RP24096 with a brass stem can also be used. The bottom of the stems is stainless steel with a smiley face opening.
The RP8230 stem, seats, and springs can also be used. This stem has a ceramic bottom.

How do i remove a Delta RP1740 stem
Hello Jim L,
Thank you for contacting us, I would be happy to help you.
To remove RP1740, first, you would need to turn the hot and cold water off at the shutoffs. Next, remove the set screw in the handle to remove the handle. Lastly, the bonnet nut is what holds the RP1740 in, once you unthread the bonnet the old stem will come out and the new stem can be put in.
Please contact us back if you have any questions or need further assistance.

Nicole

Why is there a metal plate on bottom of RP1740
Hi Bill,
Thank you for your question about the Delta Faucet model RP1740.
This stem assembly is designed so that a rubber seat and spring press against the metal plate to seal the valve. As the stem is turned, the hole in the plate allows the faucet to let water flow.
Please contact us directly if you have any additional questions!
