hi, i need some assistance with a shower drain... i'm installing a Kohler shower base and 2" drain over 2" DWV copper pipe. non-sweat drain calls for lead & oakum installation. i was given a bag labeled "LEAD (FABRICATIONS/FORMS)" - looks like steel wool - from Mayco Industries, LLC, by a plumber and told it could be used without the oakum, and without heating it to molten liquid, just gently pound it in between the drain body and the pipe. i am attempting to contact Mayco, in the meantime, is what i was told true - no oakum, no heating required?? doesn't sound quite right to me.
thanks...

That is lead wool and it is rarely used, at least around here. The only time I can see using it would be if it's impossible to pour a joint, which obviously is not the case on your installation.
The oakum is actually what creates the water tight seal, the lead only holds the oakum tightly packed in place. You may want to get another type of shower strainer to connect to the copper pipe, maybe one with a compression rubber donut that gets tightened down from the top. Or use the strainer that you have and pour a lead joint.

You need the oakum, and I have never seen a lead wool joint caulked sucessfully using just lead wool. It is normally only used for minor repairs.

The lead wool is just about never used for new joints.
Stop in at a local plumbing shop that does alot of repair work, show them what you were sent and ask what they have for shower drain connectors.
Purchase what you need and give them the lead wool, they should be able to help.

If you have a cast iron system, that is the best way to attach the closet flange, and maybe the shower and mop sink drains.

There's still a few of us left that cut in 'kaphers' ? Sometimes there's no other option...I haven't broken out the lead pot in years but I know exactly where what we call the 'lead box' is in the shop.

I pour about 25 to 30 lead joints a day. Unfortunately oakum is getting pricey because the oakum plant suffered devastaion at the hands of hurricane Katrina.

I just moved to AZ from chicago. I was a small 2 man shop in Chicago and still poured lead joints often. I have a feeling my equipment is gonna get dusty out there though

I am not sure if I could even get fuel for my Clayton-Lambert furnace.

Only us old timmers that use todo it all day long with XH pipe.
I think the new kids are kind-of-afraid of even pouring one on vertical piping let alone on horizontal piping using a running rope.
