Next door did mention they get a humming sound from there pressure reducing valve at night. Could be this? Or it could be humming as getting the buzzing coming down the mains from another house
Thanks slight issue with the first bottom 3 tiles in the corner. Sound/feel loose at the top when tapped. The bottom and middle of these 3 tiles feel ok. Needs regrouting would grout hold the top of them that sounds slightly loss?
I have some grouting to do in a bath area first too rows around the bath. Imagine there is no way of doing this so you can grout and silicone afterwards the same day/visit. Even with quick setting grout it wouldn't work
And when pressure goes up at night it starts vibrating and doesn't stop. Someone mentioned could be air pockets in the mains can't see it as high pressure
Wondered if was maybe a loose jumper or something in someone's stop tap. When the water hammer starts at night it's constant. Not something that stops when you open or close a tap
With regards to fitting a shock arrestor. I am fitting a pressure reducing valve. This will fit after my mains stop tap. If the shock is coming of the shared mains would I be best fitting the shock arrestor between my stop tap and before pressure reducing valve
When removing silicone and resealing a bath. Do I need to also remove the bead that goes up with wall from the base of the bath and the corner of the room where the tiles meet?
