Hi Claxton,
Thank you for your review of the Delta Faucet model 58569-PK. Please accept our sincere apology for the inconvenience you are experiencing. We appreciate your feedback and are happy to help.
To securely combine the two showers, insert the top slot on the hand shower into the tab of the shower head. Push the hand shower into the shower head until they snap together.
Please reach out for assistance or if you have any questions!
Best Regards,
Bryan
