Intend fitting an extra toilet in the bathroom which is next to the existing separate toilet. Easiest waste pipe run is to tee into the existing toilet waste pipe which in turn tee's into the soil stack. Will this create problems with syphoning?. If so, will an automatic air admittance valve solve the problem. What size valve needs to be fitted & where in the pipe run should it be fitted.
