i have to move it out of the way for another project, so going with 2 inch won't be any more/less work then staying with 1 1/2 inch. I just didn't know if I could get a bigger tub drain instead of the 1 1/4. I would guess the actual drain hole to be 2 to 2 1/2 inches. i do have my bath sink connected with the tub drain as well, but that will stay 1 1/2, no point going bigger. Bigger is not always better when it comes to drain lines. The only place I might have any issues i think, is when i connect the 2 inch to the cast iron hub for the main stack. There is currently a 1 1/2 inch galvanized piece threaded in to the hub of the Y. It looks like 2 inch will fit into the cast iron hub if I take out the galvanized piece and the female adapter that is leaded in to the hub. Worse comes to worse, I will change the main out to PVC. Don't really want to do that, cast iron drains are much quieter, and that is a lot of work.

Usually this will be prescribed by the size of the hole in the tub and that will be what you already have. This is often inch and a quarter. Unless there are other fixtures emptying into the branch and unless the line isn't well vented you won't likely notice any difference in performance since the narrowest point is right at the tub. The cross sectional area of the narrowest point will determine how much fluid will pass through it and this will be the exit from the tub from which you can deduct the area of the cross and mechanical opener or any other obstruction often included to keep your body piercing jewelry from going down the drain. This will be less than the inch and a half you already have. Remember too that the cross sectional area follows the inverse square law. That is, for example, if you reduce the diameter by half, you reduce the cross sectional area by four. To demonstrate this, a square one inch by one inch is one square inch. Double this to two inches by two inches and the area is four square inches. An inch and a quarter outlet will carry a lot less water than an inch and a half pipe is the point. While I wouldn't discourage you from meting code be sure it is what you need and want to do before getting into substantial demolition because the rewards aren't likely to be significant. ----- Original Message ----- From: Michael Baldwin To: blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com Sent: Wednesday, May 14, 2008 9:10 PM Subject: RE: [BlindHandyMan] Tub drain That is the plan, to make it all 2 inch to the main stack. that is what codes says I need to do, and that is what I should have done in the first place. I just didn't know if I could get the tub drain as 2 inch though, or if I had to use what is there which is 1 1/4 and then connect that to the 2 inch drain.

If you are going to 2 inch pipe I'd take out everything before that point so it's all the same size in the end. You'll appreciate the faster draining too. ----- Original Message ----- From: Michael Baldwin To: blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com Sent: Wednesday, May 14, 2008 10:25 AM Subject: [BlindHandyMan] Tub drain Okay....when you have a shower, by code it needs to have a 2 inch drain. Well our tub/shower drain has the standard 1 1/4 drain, that goes to a 1 1/2 pipe. Does anyone know if I can get the tub drain in a 2 inch size, or do I just need to make due with the 1 1/4 and connect that with a 2 inch drain line. I originally plumbed it with the 1 1/2 cause I didn't know better, and now I do, and now I need to relocate the drain for my current project, which I will post on later.
