Great Rough-in for wall faucet
A very solid well designed rough-in. I like the sweat connections.

Great product & great value. Our plumber had no issues with installation, and it works great thus far. We finished the install with Delta Trinsic 1.2 gpm wall mount faucet and love the look.

in wall faucet valve
the overall installation of this product was obviously a little more complicated then a regular sink faucet, but the completed look with the faucet assembly makes it worth it...I'd definitely recommend this if the in wall faucet is the look you are going for

Does what it should!
[This review was collected as part of a promotion.] Rough in valve arrived quickly and was exactly what I needed. Quality is great and what you would expect from Delta.

Q&A
Is this the correct rough for the Trinsic T3559LF-WF?
Web site says that the 3559LF-WL, which is combo of both the Trinsic wall-mount lav faucet trim and its rough-in, has been discontinued. The two parts (the trim and the rough) need to be purchased per item, and this Tesla rough is the one to use with the Trinsic. Yes?
Hi KF Park City,
Thank you for your question. The R3510-WL is the correct rough-in valve for the T3559LF-WL.
Best regards,
Jon

How Tight Should the Valve Cartridge Sleeve Be?
I'm trying to assemble this product with a Delta trim kit. I screwed the valve cartridge sleeve over the valve cartridge and onto the valve body. Then I tried to attach the valve trim and handle,... it didn't fit properly because the valve stem didn't protrude far enough to attache the handle screw. I decided that was the result of the valve cartridge sleeve no being fully engaged on the threads. So, I tried to tighten it with a pipe-wrench,... the result was that I destroyed the valve cartridge! What am I doing wrong?
Dear TIm,
Thank you for your question. The Delta cap/sleeve assembly for the Delta Wall Mount Rough-In R3510-WL should be hand tighten when installing it. Also, this installation requires 1/2" (13mm) copper tube fitting to extend 1 1/2" (38 mm) ~ 4" (102
mm) beyond the finished surface, for proper handle/valve part installation.

Correct O-ring location?
Page 3 of the installation sheet appears to show the o-ring belonging on the male thread of the manifold, however, the only o-ring supplied came pre-installed on the male thread of the housing. Which location is correct?
Thank you for your question, Matt. The o-ring should go in the groove on the front of the bonnet nut.
Best regards,
Jon

What is the best way to level and secure the valve body so it is level from front to back. Ancor screw underneath tends to tilt it downward so it it not level.
Hi, David!

Can this valve be mounted upside-down?
What happens if it is installed upside down though? I'd like to put the valve handle above the spout, rather than to the side. Will the valve not function correctly? It seems as if the mixing mechanics would be the same.... Thank you to anyone who can explain why I shouldn't do this.

I have two of these valves used with T3559LF-WL Trinsic faucet trim. One moves easily, while the other's action is quite stiff and hard to move. These were installed by a professional plumber. Is there any way to correct the stiff acting one?

How much space should one leave above the portion of the valve body that turns upward?
Thank you for your question, John. The space needed above the valve will depend on the trim. Please refer to the Technical Specifications for the trim kit that you plan to use.

I need to extend this valve through my 3cm slab backsplash. Need Extension Kit for that, what is the part number?
Hello!
Unfortunately we do not offer an extension kit for this valve. You may need to uninstall and reinstall the rough-in to accommodate.
Please reach out with further questions!
