            Is this the right valve to install with non diverter tub spout connection? Or which one will be best? I only need to connect a tub spout (no showerhead).

              What size cartridge fits this
              ByDec 28, 2024
              2 Answers | 
              Answer This Question

              The valve body itself doesn't include a cartridge. The cartridge is included with the compatible trim kit you choose. This valve works with single, dual, or dual thermostatic cartridges, so you'll need to select the trim kit that best suits your needs, and the correct cartridge will come with it.

              By|Jan 30, 2025

              Hello, Thank you for your question! This rough-in valve will utilize cartridges from the 13/14, 17 and 17T series shower units. This will depend on the trim kit you have installed and when the valve was installed. Please contact us directly by phone at 1-800-345-3358 or email at customerservice@deltafaucet.com if we can be of further assistance at this time. Please reach out with further questions!

                I installed this part and it’s been working fine, but all of a sudden it isn’t letting hot water come out. What’s going on?

                  The Delta valve body is made from solid brass making it easy to sweat fittings to it. I use these rough in valves all the time and will continue to use them. I’m very pleased with the quality of this product.

                    Excellent Design, Gteat product
                    My bath does not have seperate shutoff valves. Once I sweat in the plumbing to this valve I coud shut off these valves built into this rough in fixture and turn on the water source to the rest of my home. This allowed me to complete this project with water still available to my home.

                      Recommended Necessity
                      Simple installation as long as you have the right fittings. Not exactly for the typical DIY'er as it involves making 100% watertight plumbing connections. For remodel construction, fittings required will depend on your existing plumbing. I was able to use "Sharkbite" fittings to make the transition from existing tubing to threaded connections. More expensive to use the "Sharkbites" but much easier and less labor.

                      Great product. Easy installation.
                      Screw the valve into a piece of plywood or secure on some surface to tighten female pipe adaption into diverter. I used "Sioux Chief Model # HD647-CG2 Internet # 205058319 Store 1/2 in. Lead Free Brass Slip x FIP Adapter" female brass to cpvc transitions, worked great. The Delta Arzo Model 17, fit great and looks very classy. Delta is best quality. Also a Price Phister diverter for the outlet control is installed inline below.
