How in the world...

Would you guys pipe in a Gorton #2 in this location? Pipe is a little over 20' long and I am scratching my head on how to do it. There is virtually NO room between the wall and the elbow and there is no pipe movement at all.

I'd try to bust one or both bushings out and then pipe a 90 or 45 in and then likely try to squeeze multiple G1s in due to height.

Do you think you can spin a 90 on a short nipple into that without hitting the wall too much or is there not enough room?

Is the wall plaster\drywall or concrete?

What size thread is the present air vent? If it's 1/2" you could put an elbow there and then 3 Gorton #1's off that elbow, just make sure is a little slope back towards the elbow so water does not get trapped.

3ea #1's is about 0.99cfm while a #2 is 1.1 cfm.

@ ChrisJ - Foundation wall - concrete. That's the goal here is to try and spin a 90 on the elbow and go with an antler from there but I don't think I have the room.

@ BobC - I can go with the 3 x #1's if I could just get an elbow in. I am going to give it a shot next weekend.

This is at a next door neighbors house and I freaked last weekend when he showed me what a "great job" the painter did in his new laundry room. The vent is way too small but now it is painted shut big-time. So, off we go to replacing it. Same situation for the other loop on the other side of the basement but I can easily get a #2 in that location on an antler. Its not smack-up against the wall. Both loops jusxt happen to be a hair over 20' long so the #2's (or variants) will work well.

Thanks, Guys.

What about welding or brazing a fitting on?

What about a 45° elbow? I don't think they need as big of a radius to swing. Once the first one is on you could add a second and adjust it for slope, add another nipple and 90° elbow (or tees for multiple vents) and then the vent. Since that is a reducing tee that flares out below that I would think there is enough room to spin a small 45°, but it's sometimes hard to tell in pictures. Oh and I think a malleable fitting with the thinner collar might allow a tad bit more breathing room as well. Just a couple thoughts.

Welding? I didn't even think of that. Could use a nickel electrode which I have laying around. Could go the 45° route as well since the fittings are inexpensive and I have some time to play around.

Thanks again, guys!

Being how the air vent is on that 90 in the "forbidden zone" for main venting, how about just leave it there, back up 15" or more and drill and tap for a 1/4" IPS fitting. A Gorton #2 only needs a 1/4" tap.

If you still had to use the 3 smaller vents because of height than 3 taps could be installed. I would keep the taps maybe 6 to 8" apart on the top of the pipe.
This has worked for me on 1918 pipes and was easier than I thought it would be.....drilled and tapped quite well.

Don't have the painters back to touch up your new work.


Edit:
Welding.....well maybe will need the painters...

Steam_Starter

Forbidden Zone - yeah. That hit me too. Other one is in same location on other side of basement. I am going to try the elbow route first and see where it goes from there...I will post a pic of the new work (when I am able to get it done...)

Thanks again all...

What about threading a union with a close nipple? You could make the whole antler removable that way.

You just made me feel kind of like this poor girl.
Not near as bad, but a similar hint of the feeling.

Sorry -- that one went right by me.

A union with one male NPT end would drop the height a bit.

Installing a union would allow prefabricating the antler (easier now) and make replacing or augmenting vents a lot easier later.

Sometimes the obvious eludes us....this picture is for me.

We do this all the time when then vent is up inside a floor joist, with little room to swing a wrench.

Blatantly obvious. As my son says..."Dad, can you get with it?!"
