I attached a couple photo’s. Would like to get a couple opinions.
The water heater venting has a secondary opening about 3’ down the line. The opening is pulling air into it at the time I checked it. I checked the water heater for down drafting and it was not doing it at the time I checked.
Though I think it could cause some downdraft? I’m unsure of this statement.
I recommended contacting a plumber for repair because it could be reducing the draw/venting at the water heater. It should be sealed off.
Anyone see anything else I’m not?
I already addressed, the improper pressure relief value. The home owner did it himself. Note how it’s aimed toward the ceiling of this basement!!!
