[Mgs] clearing the drains in the heater system

[Barrie Robinson]

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.
