The installation is reasonably straightforward for any person competent in DIY although precise times will vary depending on the tools you have available, your skills, the fabric of the building and any unusual requirements for routing the vent pipe and/or urine drain. Assuming that you are venting out directly behind the toilet, a typical installation in a building made from wood would take around 3 hours. For solid walls, there will be additional time in drilling holes through brick/concrete. Routing the vent pipe and/or urine pipe to alternative locations will entail additional work. In our webshop, there are installation videos shown against the main products.
