Max,
No that does not make sense ! The drain tube goes up to the intake
so no exhaust fumes there. The bulb is probably there to allow a
"squeeze". So squeezing it blew out any blockages - obviously
designed by a nitwit ! Perhaps someone thought a BIG blob of water
held in the blob would force out a constriction. But hydraulics says
it is not the area or mass but the depth that counts - thus a tube
would have been fine. It is all so simple - tube to allow water to
drain out - blockage removed by pokey-up wire. Nothing simpler.
