    hi all

    New to the forum and I am a diy homeowner doing as many various type improvements myself. Currently working in our downstairs cloakroom, wanting to lay a new floor and replace the sink and toilet. Excuse my ignorance, but not sure what this gray vertical pipe connection is? Looks like some kind of an air vent perhaps? Can I remove and it, break the floor out, install a 90deg bend and burry the toilet outlet pipe with a 90deg bend and run in the floor?

    I’m on septic tank, perhaps it has to stay that case I would need to cover/mask it somehow...

    It's an air admittance valve and depending on how your waste system is piped up, it may need to stay there, although technically it should be higher up.

    No I would leave it where it is you can box it in but need to put vents on to allow fresh air
