The J Bend is easy to install to your existing sink drain system. Recommended procedure for installation P or S type trap:

1. Turn off water at the tap.
2. Remove old J Bend.
3. Remove new nut A and washer on tailpiece.
4. Place new washer on wall tube or floor tube. Use old nut B as it is not removable unless a complete trap is being installed.
5. Position J Bend. Tighten nuts. Run water to check for leaks.

Installation hints:

1. Since it "traps" items that may fall into the drain and blocks gases from the waste drain system, water and dirt will be present in the existing trap. Place a bucket under the old trap before attempting to remove it.
2. Put thread sealant tape on the drain threads before attaching nuts. This will provide a better seal against leaks.
3. Use a scrap of cloth to protect the chrome finish on the nuts when you tighten  with a pipe wrench.
