Hi,
I am installing a new en-suite toilet upstairs in a new location , the soil stack is installed by my builder going downstairs directly and into the ground where the main sewers are. He’s installed the air admittance valve on the floor below , which is slightly below where the toilet is.
I asked the plumber if it’s ok as it’s below the toilet , he said yes, but most places I read online saying it needs to be above a certain level.
Can you help me please , as the plumbers insisted it’s ok.
