What is the correct fitting?

[europe72dead]

hello, I'm replacing a fitting that connects my sink to a wet/dry vent. I’m wondering why there’s a clean out fitting here instead of a sanitary tee? This is from 1929, the wet vent is a 2” lead pipe, the dry vent is 2” galvanized steel.

replace fitting with san tee, correct?

Replace all the lead.

Use a sanitary tee to transition from horizontal to vertical.

What I thought, thanks for confirming. Was planning on replacing the lead with pvc on the wet vent side and using a fernco after the sanitary tee to connect to the galvanized dry vent. I shouldn’t have second guessed myself.

did they not have sanitary tees in the 20s?

They had them, they just used whatever they had on hand. Times were tough.

Check the galvanized vent. A lot of those are plugged from years of rust and birds and what not.

I understand lead is dangerous and should be removed, but I have to comment on the workmanship on the leaded joint. It really is a work of art, and kudos to the plumbing craftsmen and women of yesteryears

My dad gave me a few ladles and a a wiping rag???? along the ago for wiping lead joints

I replace lead drains when given the opportunity because they’re usually worn out and my drain cable will go right through the wall of the pipe when it’s worn out.

Most of the galvanized vents I find are in great condition, but not all. Depends on several factors but one being how much sewer gas the vent is venting.
