Customer stated that water was leaking from basement bedroom ceiling and light fixture. I arrived and found that water to the house was turned off after customer noticed water leak. We turned water back on to the house and I did not see any water leaking from pipes in the area. Customer stated that she noticed the leak after shower had been taken in bathroom above where the leak was coming from. We turned shower on and immediately noticed the water starting to leak. I advised customer to not use that bathroom and we will have a plumbing technician out on Monday to examine the shower drain.
