PRODUCT FEATURES
The Dorval® Bathroom Collection diverges from conventional expectations with regal accents and a powerful design that commands your attention. Inspired by the feminine lines of French architecture and the regal stature of German castles, the Dorval Bath Collection balances grace and power in this modern take on new traditional design. With separate handles for volume and temperature control, this Delta® tub/shower provides a more refined showering experience. Simply set the water at your preferred temperature and turn the shower on or off with the volume control handle - without interrupting your set temperature. Delta pressure-balance valves use Monitor® Technology to protect you and your family from sudden temperature changes.
  • Control volume and water temperature independently with two separate handles for more refined control of your shower experience
  • Monitor® pressure balance valve keeps water temperature within a safe ±3° F (±1.6° C), helping to protect you from sudden changes in hot or cold water pressure
  • Trim kit only, must order MultiChoice® Universal Valve separately to complete the unit
  • Recommended rough-in kit R10000-UNBX
  • ADA Compliant

Rated 5 out of 5 by from Great Look & Functionality [This review was collected as part of a promotion.] Great look. Extremely functional with the temperature and water pressure adjustment separate.

Rated 4 out of 5 by from Love the look, not the upkeep Looks beautiful. Admit to being disappointed in how hard these are to keep clean. Am still working to remove the finger marks left by the plumber. I thought these were not supposed to spot as badly as the cheap garbage.. well, these do. Plumber replaced our water softener as well, so it’s not that. Can’t figure out what product to use on all of these as I have pretty much the whole Dorval collection in a fully gutted bathroom remodel. For what these cost, they should sparkle with minimal effort.

Rated 2 out of 5 by from Flimsy feels cheap. Bought and just got it installed. It is bulky, and feels that it will brake anytime. It is wobbly when turned. Feels like cheap plastic. So disappointed switching from GROHE to this. Wished could return it.

Rated 2 out of 5 by from Flimsy, feels cheap, like if it is plastic. Replaced our nightmare constantly braking GROHE. Our wall was thicker than mass built houses. This required an extender adapter, additional $$ and calling to place the order. This DELTA is flimsy (temp regular handle). Feels cheaply made. Hope it lasts.

Q&A

Does the T17056BL comply with ASSE 1070

Asked by: Mark
Hi Mark, Thank you for your question about the Delta Faucet model T17056-BL. ASME A112.18.1/CSA B125.1 covers ASSE 1016, but does not cover ASSE 1017 or ASSE 1070. Please reach out with any additional questions! Best Regards, Bryan

My handles are loose. How do I tighten?

Asked by: Mickey1960
Hi Mickey1960, Thank you for your question about the Delta Faucet model T17056. The handles are tightened with the set screw under the cover on the temperature handle. I recommend the parts diagram to see how the handles are put together. https://media.deltafaucet.com/PartsDiagram/DPD-B-T17056%20Rev%20E.pdf Please reach out with any additional questions!

My valve hot and cold handle delivers water temp in opposite directions. When I took the handle apart the "hot side" is on the top and not at 9 or 3 o'clock positions. Did my installer put it in wrong?

Asked by: Jeff
Hi Jeff, Thank you for your question about the Delta Faucet model T17056 Dorval™ Monitor 17 Series Valve Trim Only In Chrome. Please accept our sincere apology for the inconvenience you are experiencing with the temperature control. We are happy to help resolve this issue for you. If the temperatures are revered, the cartridge can be reversed, such as for a back-to-back installation. For a standard installation, the cartridge "hot side" should be on the left, and on the right for a reverse install. Yes, there may be an installation issue if the notches on the brass body are not on the right and left sides. The word "UP" should be on the top of the valve body. See the installation manual for more information: https://media.deltafaucet.com/MandI/107529%20Rev%20D.pdf Please reach out if you have any questions or need additional assistance. We appreciate your business and look forward to continuing to serve you! Best Regards, Bryan Digital Communications Specialist

Kayra Monitor 17 valve trim only, chrome. Having an awful time with installation. Contractor muddled up trying to install this with no luck. Plumber gave it a try - can’t secure the escutcheon and temp not hot enough. Need a Delta plumber in Kalamazoo.

Asked by: Molly
Hello Molly, Thank you for your question! I am happy to help you! We do not have any local recommendations for installers, I would check with local plumbing supply stores to see if they have anyone they would recommend. Please contact us back for any further questions. Best Regards, Nicole
