Delta RP41478 Nut and Adapter - Replacement Part

Hello Neoistheone, Thank you for your review regarding Delta Faucet RP41478! We apologize for the issues you are experiencing, we are happy to assist! The RP41478 is an adapter to change the threaded vegetable spray connection of the faucet to a quick connect. It is easy to install, given the limitations of the space under the sink. 1. Remove old vegetable sprayer hose. 2. Remove any sealing tape or debris from the threaded connection on the faucet. 3. Apply a couple of wraps of thread seal tape to the threads only, of the faucet connection. 4. The orientation of the pieces are important. The adapter has a conical end and a cylindrical end. Position the conical end up. The coupling nut's opening is wider on one side than the other. The wide side should be up. 5. With the conical end of the adapter up, place the cylindrical end of the adapter into the coupling nut. 6. Attach the adapter and nut to the threaded connection of the faucet by tightening the nut. Hand-tight should be sufficient. If not, tighten ¼ turn at a time until the leak stops. Please also note the RP41478 comes with two universal adapter pieces that are not used in this installation. They are used to adapt the smaller threading of other faucet brands to the thread size the connector nut uses. We look forward to better serving you in the future.
