Yes. The N.Y. Code and L.A. Code traps are designed to work for this application.
How is the size of the tubular product determined for each application?
The most common tubular product sizes are 1¼” and 1½”. These sizes are available in brass and plastic tubular products. The trap adapter connection to the branch drain in the wall will determine the largest size of tubular product which can be connected with a slip nut and washer. This point of connection can also be reduced for 1¼” tubular assemblies, with a reducing washer and slip nut. Bathroom sink installations are normally completed with 1¼” tubular products, but 1½” tubular products will also work. Kitchen sink installations can only be completed with 1½” tubular products.

Water hammer will expose any loose pipes throughout the home and create banging sounds. If you locate the loose pipe(s) and secure them with the appropriate strap or hanger, you will be able to reduce or stop the banging sounds.
