Hoping someone can help.
I have two pipes coming out of my basement slab. The big iron one is obviously the sewer line, but it's the smaller one next to it (metal & then PVC) which has me confused. The smaller one comes out of the concrete slab and goes up into the basement ceiling. Above the two pipes are 1st & 2nd floor bathrooms. It's a 1936 Sears house in Arlington, VA. Given the house's age, I'm assuming it's not Radon...
[Background. We've caught 2 Norwegian rats in the house walls with traps, and since the perimeter is secure (per our exterminator), our exterminator is claiming the rats are coming up one of these two pipes. We're scheduling a sewer smoke test to determine if there's a broken sewer line pipe in the house, but before I throw down that $$ I'm hoping to determine whether this second pipe might be the rat highway.]
Any help/advice anyone can provide would be appreciated.
