macerator teaser

[nigel priest]

I have a tolet pan connector discharging to the sewer through the floor. I have no external stack. Can a macerator discharge be bossed into the w/c pan connector to allow the macerator to dicharge?

I would advise a soil tee peice fitted in place of bent pan connector at rear of existing w/c and a air abmittance valve fitted on top then join macerator outlet into tee

id just use a bent pancon with a inch and a quarter multifit on it you probably dont even need the aav as the macerator has a vent on it and a nonreturn valve on the outlet
if the touilet flushing does pull the macerator pipework it will suck air from the macerator vent smell cant go back due to the non return valve

Was not worried about macerator,was worried that normal wc flushed then macerator activated and possibility of part water trap being pulled out of normal pan

cant see a threquarter discharge pulling a 4 inch trapobviously if it did then youd rethink but unliklkey
