Hi Guys,
I recently replaced a 21 year old shower head with a new one purchased at Bunnings. Due to the plumbing extending out of the wall further than the new head was designed for the gentlemen at Bunnings said to use the old backing plate.
I have noticed a small leak at the base of the backing plate. Just wondering if this means it is leaking internally and should it be something I worry about? I have attached some images which hopefully will show the small drip/leak.
Thank you so much for your help 🙂
