Thank you for your question regarding the Delta In2ition® 4-Setting Two-in-One Shower and I am happy to assist you today.
The water pressure cannot be adjusted internally for this unit and I apologize for any inconvenience this may cause. Installed inside of all of our shower heads and hand showers are flow restricting devices which we do not advise removing for many reasons. If the restrictor is removed, it may result in a painful experience for the user as the unit may no longer perform as designed. The unit will also no longer meet specific plumbing codes if the device is removed.
I hope this information is helpful and if we can assist you with anything else going forward, please do not hesitate to give us a call at 800-345-3358 and we will do our best to assist you where we can.
