We performed leak search . Customer had water damage in garage ceiling . The hallway bathroom is right above damaged section , we ran water and didn’t find any leaks in drain not pressurized water lines . We did notice tub spout had some water shooting back and getting through tile gap . So we replaced tip spout and added plumbers putty in gap. We also noticed a lot of water was getting on floor , advised homeowner to install tub water guard and silicon certain areas to prevent water going down to garage
