Augered men’s lab toilet. Cleared unknown. After clearing noticed toilet was filling slowly. Replaced fill valve and supply. Noticed that sometimes when flushed water lines feeding both men’s and women’s toilet for lab the lines would become very loud. Possible chance the shutoffs to both toilets are failing. Informed staff that if it continues we should replace valves. This should be performed before Medical Center opens so we will not disturb water supply during business hours. No warranties to issue. Commercial.
