Hey guys,
I just installed a Toto Drake in my guest bathroom. Long story short, I plunged it and used a half gallon of dish soap after noticing it didn't flush as well as my powder room Drake, after this it works as I expected. This bathroom doesn't get used very often so I never noticed it was slow with the 30 yr old toilet (I only bought this house a year ago).
So with the thunderous flushing power of the Drake, I just noticed that my sink trap in the same room is being siphoned. I took an inspection camera down and it is being sucked enough to lose the air lock. Is there anything I can do to prevent this? The vent goes up the wall behind the sink and takes a long horizontal path through the attic and eventually through the roof. Can I add a junction in the piping in the roof just before it goes horizontal to add another vent through the roof to let more air in?
Not sure if this toilet is too powerful for the vent design, no clue on this? It's a 2" ABS vent.
The bathtub takes a more direct path to a different 3" stack, not sure why, but it uses the same vent line. The tub is not being siphoned. I'm assuming that the sink is the path of least resistance.
Thanks
