Drip leg

@ August 29, 2014 5:41 PM in Going around obsticals

I've considered a drip leg as well.

Unsure of what the smallest size I could safely use is though as I'd need to drill through a stone foundation to make it happen. I'm guessing 1/2" would be the smallest recommended?

The radiator is a small 15sqft unit.

Shimming

@ August 29, 2014 5:03 PM in Going around obsticals

icesailor.

As I said previously,

The current straight pipe is pushed against a pvc pipe going to a toilet. Instead of shimming the radiator I would just install a shorter nipple connecting it if need be. It's not possible.

it is also not possible to move the pvc pipe for the toilet.

I'm curious, why would it pound?

I'm considering doing something smiliar to the attached diagram to get better pitch on a runout to one of my radiators.

The current straight pipe is pushed against a pvc pipe going to a toilet. I barely have enough pitch on the pipe to prevent hammering but right now it's been quiet. If it drops even a 1/16th it'll hammer on startup.

I'm assuming if I do something like this it's fine even if I have 45's or something to keep the steam pipe off to the side rather than directly above the bottom trap / drain as long as the bottom run is always completely filled and the top section empty?

Insulation

@ August 29, 2014 3:07 PM in What is the solution?

I bought all of my pipe insulation and covers from this website.
http://buyinsulationproducts.com/

I still have some I need to do, though I've got most of it done.

Try to buy everything you need at once because shipping cost is a killer.


EDIT: Wanted to add 1" thick is by far the best bang for the buck. If I had it to do over I would go with 2" in some areas like my crawl space where it gets really cold but I'd still do the majority in 1".

Nope

@ August 29, 2014 2:35 PM in What is the solution?

I'm not a pro either. I've done similar work to my own system though.

I'd recommend calling Jstar as I think he services Brooklyn.

Tee

@ August 29, 2014 2:22 PM in What is the solution?

If the last take off isn't exposed anywhere convenient what about drilling and tapping the side of the tee for it?

Keep it up as high as you can without risking drilling into the pipe threading and then you can vent from there.

Pipe

@ August 28, 2014 2:32 PM in What is the solution?

Where does the takeoff on the far right go and is there anyway you could use that? If there is a fitting in that pipe up above you could drill and tap for 1/2" that would be perfect in my opinion.

Another option would be to vent the return if possible.

Interesting

@ August 27, 2014 10:17 AM in Antique something??

Yep, no plugs in the first two ports, the second two have plugs. Looks like probably 3/4" NPT.

I was surprised I couldn't find anything at all on this. Usually when I find an old name on an item like this I can find something, but not this time.

Antique something??

@ August 26, 2014 9:38 PM in Antique something??

I found this in one of my crawl spaces mixed in with a pile of galvanized pipe and the big inserts that came from a converted coal boiler I assume. You know, the big iron ones that slide into the large passages.

Anyway, it appears to say Rich Fin and 30 gallons. There is some number before that but I can't make it out.


Does anyone know what this is?

Google

@ August 26, 2014 10:16 AM in Swing joints. How do they work?

I tried that, I couldn't really find anything that talked about whether or not threaded pipes actually twist and move inside the threaded fittings.

Speed

@ August 26, 2014 10:04 AM in puchasing a new ammeter, recommendations?

Icesailor,

I'm curious what type of digital meters you have used? As I said earlier in the thread cheap ones annoy me because of how slow they are.

A good quality digital meter is often faster than an analog meter movement and usually has a bar graph to indicate movement.

Hi Terry,

Please feel free to use the image anyway you wish.

Swinging

@ August 25, 2014 11:12 PM in Swing joints. How do they work?

So if I'm understanding correctly "swing joint" is a standard piping term in regards to when you use an elbow  so the pipe can "swing" to a different angle?

My assumption was it was a term only used in steam piping.

Swing joints. How do they work?

@ August 25, 2014 10:47 PM in Swing joints. How do they work?

I'm sorry if this is a dumb question but I'm trying to understand swing joints better.
Does the piping actually turn inside the fittings or is it to align piping in a way that it can flex and the actual threading inside the fitting doesn't move?

I'm having a hard time understanding if the piping actually turns inside the fitting how doesn't this create leaks?

Painting and teflon tape?

@ August 25, 2014 5:53 PM in Oh look what I found in my closet

Hi KC. Thanks! I'm happy it came out as well as it did but will feel a lot better once the whole room is painted and the new floor is down.

Finished!

@ August 24, 2014 10:19 PM in Oh look what I found in my closet

All finished. Got lucky and someone at another Lowes was willing to thread a 14 1/4" piece of 1". I have no idea how I managed to get the offset length right but I did. The horizontal 1 1/4" run out is almost tight to the joist now and being supported completely by the radiator so expansion noises should be gone.


Our baby's room is going to be warm this winter! I'm kind of excited to see how this radiator performs now and am expecting to have to swap the Gorton C out fo a #6.

So close!

@ August 24, 2014 4:52 PM in Oh look what I found in my closet

Almost done but the project is held up by a short length of pipe. I need to get a 14 1/4" length if 1" iron pipe somewhere but it seems most places won't thread something that short.


Not sure what I'm going to do now.

How much flex in piping?

@ August 23, 2014 10:39 PM in How much flex in piping?

I elongated a hole in the first floor as I need to get the pipe away from a semi-recently added wall. The issue is when I moved the runout it ended up slightly out of alignment with the hole and more towards another wall as this is in a corner.

I've included a picture of how much I need to get this to move as well as a drawing of the piping layout.

What would the pros do under these conditions?

I can pry it back to where I can thread the new pipe in and call it a day but I'm not sure if this is acceptable or not and if it will cause problems down the road.

oops

@ August 23, 2014 11:28 AM in Offsets in pipes between floors?

I just noticed none of mine have 90s.
The two large ones have a single 45 by the radiator.  So why not just do a single 45 on all of them rather than two 45s below the floor?

Offsets in pipes between floors?

@ August 23, 2014 1:12 AM in Offsets in pipes between floors?

I've lived here since 2011 and just realized most of my pipes either have, or are suppose to have an offset in them near the ceiling.  Apparently 2 currently do, one of which is hidden in a cabinet and the other is hidden in a wall.  The third I'm putting back this weekend as it was piped through the closet via copper as mentioned in another thread.
Besides those 3, two other radiators on the second floor which are much larger have a 90 deg elbow coming off of the valve.  I had wondered why those two had that setup and the others didn't and now I know, because their offset is on the first floor.  Ive attached a few photos, one is a drawing of the pipe I'm putting back in, the other is of the offset in a cabinet and the last is of one of 90s on one of the two large radiators  Makes me wonder why the large radiators are piped differently than the smaller ones.  I'd assume the two 45's is superior.

The one I am installing is along side a door, but the door is a recent addition so that isn't the reason for the offset.  These were obviously done to keep the pipe close to the wall but I don't recall seeing this in other houses?  Is this common and I've just been oblivious to it? 

EDIT : The two larger ones have a single 45 coming off of the valve, NOT a 90.  My mistake.

Supplyhouse

@ August 23, 2014 1:01 AM in Cast Iron fittings

Yep, I just ordered some cast iron to put my steampipe in from pexsupply aka supplyhouse.com


Problem is for some reason you now have to search for cast iron fittings rather than find it in a drop down menu.  Other than that, same great service and same great Ward cast iron.  I piped 98% of my boiler from pexsupply.

Meters

@ August 22, 2014 1:56 PM in puchasing a new ammeter, recommendations?

When it comes to digital meters I'm extremely picky. I can't stand how slow most of them are.

I use a Fluke 179 DMM and a Simpson 260 7P for most things.

I was just looking at a Fluke 381 which seems like it would be very handy in the refrigeration trade.
