Pump activating repeatedly after toilet flush

Category: General Plumbing

Location: Dublin

We have a pump in our house that runs normally for everything except one toilet in the main upstairs bathroom. The toilet is wall hung with a concealed cistern built into the wall. When flushed it fills partially then stops, and afterwards the pump continues to activate on and off randomly for a long time. Every other fixture in the house uses the pump fine with no issue. Suspect it could be a slow leak in the concealed cistern causing it to slowly empty and keep triggering the pump. Looking for a plumber to diagnose and fix the issue.
