Dripping noise inside new toilet that only happens during use
We've recently had a new bathroom with toilet (s trap) installed where there was no plumbing previously. No sign of any leaks or issues, but the toilet makes a weird dripping noise during use, basically when any liquids / solids hit the water inside the pan. You don't hear it during or after flushing. It's a quite fast drip that slows and stops after about 30 seconds. It's seemingly coming from lower down, possibly the waste rather than from the cistern. Any idea what it could be? Is it something worth investigating further?
