Morning,
I have a hand wash basin to install in a 1st floor cloakroom. Wc is connected through stone wall to cast iron vent pipe outside. House is Grade 2 listed farmhouse. Do you think it will be ok to run new basin waste with anti vac trap down through floor into kitchen below, approx 2.5m down plus 1-2m horizontal to sink area before going out through wall. Pipe size could be increased from floor level or just below to 40/50 mm. This is what client is hoping for.
