Responded to a water leak service call where customer reported previous service history. Upon inspection, determined primary issue was not the water line leak above laundry tub but rather a clogged main drain causing water to back up through floor drain in mechanical room when basement bathroom fixtures were used. Confirmed previous service in 2023 that included camera inspection and drain snaking. Recommended customer contact specialized drain service (Clog Un-boggler) to clear main drain line to city interceptor and provided estimate for separate water line repair.
