Thank you for your question. There are two parts to the valve cartridge assembly, the top and bottom. If the bottom part of the cartridge is still in the valve body, please remove by taking two flat head screw drivers or butter knives and putting them into each side of the cartridge, between the inside of the valve, and work the cartridge out. Once the bottom of the cartridge is out, connect the two parts of the cartridge together. To reinstall this back into the valve, push the cartridge straight in. Do not twist the cartridge or the cartridge will separate again. If you should need anymore assistance, please contact us back.
