Steam main vents

Steamhead (in transit)

and if you can't get the drill in position to drill the hole in the top, you can drill in the side and elbow up. Leave a bit of pitch in the short horizontal pipe, towards the main.

Steam main vents


I recall a few years back that Steamhead gave some great advice on tuning a one pipe system for fuel savings. He mentioned, I think, burning a hole 15" from the end of an unvented main and welding on a fitting for a nipple and air vent. It would be greatly appreciated if anyone has info on this. I think the fitting was called a "weld-o-let"??? Not sure what it is called and where to get them.
Thanks again,
Sam

We only have that done

on our BIG projects, like the one in our Find a Professional ad. Click the link below to see it.

For the usual residential system, drilling and tapping works fine.

Mains with No vents

So to follow-up on what you said, is it ok to drill and tap the main vent directly into the main line it's self (15" back from the end)?

One more question

How large should the tap be? would 1/8, 1/4, 3/4???
