I can’t find anything that states the condensate cannot drain into the waste line, only it needs to drain in an “approved location”.
This is brand new construction. There is a floor drain close by. I would think the trap in the condensate would prevent sewer gas back-up, but if there were a sewer back up, then the sewage would wind up in the HVAC.
Wanted to check here before I recommend they re-route the condensate line
Posed to be a indirect waste and a wet trap, what you have pictured is not a wet trap unless the furnace is a 90% and makes condensate. Your trap has no seal in the heating season thus??? its like installing a return behind the commode!!!
Thanks guys! The furnace may be 90% (PVC vent present), but I’d need to check the data plate to make sure. Even so, then my little trap may be a wet trap, but wouldn’t prevent sewage back up into the HVAC.
I figure if I call it out, the Builder is gonna say it’s “code”, and refuse to change it, but I’d still recommend the homeowner change it for peace of mind.
Its a up flow furnace 90% and if sewage backs up that high your gona be in deep
S H I T was the furnace in a basement or first level. Regardless it is suppose to be a indirect connection
