I have installed a new triton t90sr into my bathroom however its taking quite long to stop dripping from the showerhead. Ive only noticed this a few days after installing it and this morning when i woke up, there was no drips from the shower head at all. Took a shower halfhour ago and the showerhead is still dripping! Could this be a sign of a fault in it somewhere or does these shower take this length of time to get rid of excess water in it.
