We have the following waste pipe in a ground floor kitchen:
The white pipe is a connection to our sink/washing machine/dishwasher.
The 10cm brown pipe is connected directly to a sewer chamber outside in a shared alley (the distance to the chamber is about 8 feet). This chamber is itself connected to a deeper sewer chamber, the latter being where the soil pipe from the upstairs bathroom is connected.
The problem we are experiencing is smell and noise in the kitchen when the upstairs toilet is flushed. I suspect there must be an air leak to do with the grey fitting on top of the brown pipe. I'll be grateful for advice on:
What the grey fitting is (is it an air admittance valve)?
Does it seem to be fitted properly - I must admit I pushed it down a bit.
Can I easily replace this fitting?
Ultimately a corner kitchen cabinet will be put in that place and I'd obviously like to avoid any issues after that is done.
