Leaky Cast Iron Drain Pipes Under a Flooring Slab Send Sewer Gases into HVAC Ducts

A reader (Conrad) provided us with the photographs and case history of the successful track-down of sewer gas odors in a edifice (SEWER GAS ODORS). The example began with a complaint of sewer gas odors in the building'southward heating duct work organisation. Equally you lot tin can see from the "before" and "subsequently" photos, this case involved the following combination of circumstances:

A transite heating duct was cached in a basement flooring (below the slab) and located parallel to and immediately above a bandage iron sewer pipe (photo beneath left)
The sewer pipe deteriorated and developed leaks (photo below right)
The transite (asbestos cement -
run into TRANSITE Pipage AIR DUCT ASBESTOS RISKS) air duct was also leaky
Sewer gases leaked out of the cast iron waste line and into the heating duct line.
The repair required breaking upward the physical floor slab and replacing the leaky sewer line. We recommended replacement of the transite heating duct as well.

How-do-you-do and so glad I found your site!
I bought my house 3 years ago and it had an odor then--(45 years old,single story on foundation.) Nosotros demoed everything and still have the odor. The laundry room has a flooring drain, and at the time I thought "how cool". When I retiled the floor I kept the drain. Only apparatus at present is a washer/dryer in this room, along with a sink. Wish I had sealed over the drain (is this fifty-fifty possible?)
Anyway, people ever comment on the odor......smells similar sewage. My husband and I are here all the time then I think we are at present used to olfactory property. I'one thousand more sensitive and notice information technology more. My brother said he thought information technology could be the trap and gases. I've put water down it besides as Dymon-Liqued Alive.
I saw the pictures of drains existence ripped out of foundation and do no want to get to that expense. This laundry room sits next to a powder room with sink and toilet, but I cannot imagine they would share the aforementioned drain.
What are your suggestions? Mineral oil? Seal drain? and what with?
Assist,

Kickoff in that location are some simple things you lot tin can endeavour:

Pour clean mineral oil into the floor drain trap so that it'south not "dry" - see if that stops the odour.

It's besides simple to duct-tape a flat rubber tub drain encompass over the flooring drain.

Both of these are cease-gap measures: we don't desire potentially unsafe methane to be leaking into a building.

Before abandoning the drain by pouring physical into it I'd be sure that you lot are not risking blocking a drain inlet connexion from some other plumbing fixture nearby.
