PRODUCT FEATURES
Familiar geometries and subtle curves in the Tetra™ Bath Collection combine to bring a sleek, architectural look and feel to the bath. Delta® showers with TempAssure® thermostatic valves are engineered to make sure you don'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. Lumicoat™ Finishes are guaranteed to resist water spots and mineral buildup and easily wipe clean without the need for cleaners or chemicals. The ultra-sleek surface repels liquids, resisting water spots and staying cleaner longer, so your faucet’s most commonly touched areas stay beautiful. Integrating separate controls on one trim with the MultiChoice® Integrated Shower Diverter allows you to 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. You can install with confidence, knowing Delta® products are backed by our Lifetime Limited Warranty.
  • Lumicoat® Finishes easily wipe clean without cleaners or chemicals and are guaranteed to resist mineral buildup and hard water stains on the product’s most commonly touched areas
  • TempAssure® thermostatic valve keeps water temperature within a safe ±3.6° F (±1.7° C), helping to protect you from sudden changes in hot or cold water pressure
  • MultiChoice® Integrated Shower Diverter provides a sleek, streamlined style for your shower while eliminating the need for an additional diverter valve
  • 3-function diverter offers 2 individual positions and 1 shared position
  • Trim kit only, must order MultiChoice® Universal valve rough (R22000) separately to complete the unit
  • Top handle controls diverter functions

Rated 5 out of 5 by from Clean lines and well built [This review was collected as part of a promotion.] We were looking for a shower valve with square lines for our son's bathroom. Delta's shower valve fits perfectly for the masculine vibe we're going for in his bathroom. The valve's lines are clean and the shower handles function smoothly. I would purchase this product again.

Hello.  I just had the T13420 shower faucet in stall in my bathroom.  But the water pressure dropped significantly on this faucet,from replacing a 4 handle  faucet. Would this work better than the delta just installed?maybe because it diverter is separate

Asked by: Emer
Hi Emer, Please accept our sincere apology for the inconvenience you are experiencing. We are happy to help! The WaterSense labeled shower head included with T13420 uses at least 20% less water than the industry standard. To troubleshoot an issue with the water pressure, we recommend flushing the faucet with the shower head removed. Turn on both handles for two minutes and rinse debris from the shower head connection. If the issue remains, turn off the water supplies to flush the valve rough with the cartridge removed. Be careful as this will shoot water across the shower to flush out any debris. Changing to a shower trim with an integrated diverter would require also changing the plumbing and valve rough. Typically a diverter will reduce the flow rate but a thermostatic valve can provide more flow rate overall. This should only be a factor if using more than one shower feature at a time. The faucet's maximum flow rate will depend on the home water pressure and other plumbing factors. Please reach out for further assistance or with any additional questions! Best Regards, Bryan Digital Communications Specialist

Hi regarding the Tetra 17T TempAssure series trim with the integrated 3 setting diverter, T27T889-PR:  would this work in a tub and shower situation where I would only use the diverter to switch from tub to shower? 

Asked by: MountainRemodeler
Hi MountainRemodeler, thank you for your interest in the T27T889-PR! This trim is not compatible with a tub. This trim would be used to control two shower features, like a showerhead and hand shower or a showerhead and body sprays. One setting for each and one for sharing. Please contact us directly if you have any questions or need additional assistance. Best Regards, Themar Digital Communications Specialist

In the description it says there are models with 3 or 6 settings. What are the settings for? I'm trying to find a control which can also divert to a shower wand mounted along side of the shower. Would I be able to use this item?

Asked by: John
Hi John, Thanks so much for contacting Delta Faucet Company about, T27T889-PR! The 3 setting diverter would allow for two items to be used in the shower, and the 6 setting diverter would allow for 3 items to be used, combined or individually. Please contact us directly if you have any questions or need additional assistance. Best Regards, Nicole Digital Communications Specialist

How to set valve hotter

Asked by: Hotter setting
Hi Hotter setting, Thanks so much for contacting Delta Faucet Company! It sounds as though the rotational limit stop may not have been adjusted the TETRA® TempAssure 17T Series Integrated Diverter Trim With 3-Setting MODEL#: T27T889-PR. 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).

Is this only for use in a tub with the R22000 valve rough to divert water from the tub to the shower within the tub?  Or can it be used in a shower with the diverter used for either an overhead shower or a hand held shower?

Hello Customer! Thank you for your question and we are happy to help. The diverter is for the overhead shower and hand shower while the lift rod is for the tub. With any further questions or concerns, please do not hesitate to reach out to us again. Best Regards, Carrie
