In response to Re: septictank smell
: : I have a one story house in tucson AZ and as the temps reach 100 the septic smell coming from the vents is very bad and now when the central air comes on the smell comes through all the a/c vents in the house. Is there a fix for this problem like putting checkvalves on the vent pipes?
: When you say...."coming from the vents" you mean the floor drains (traps) ? If so, make sure they are holding water as this will prevent the smell from escaping into the room. Is the roof vent stack letting the odors out (as it should) or is it plugged up with a birds nest or leaves, etc. Hube

Your underfloor ductwork has probably rusted out.
And, your cast iron drain pipe has corroded thru. LonnythePlumber
