splitting copper lines myself?


i'm installing a bathroom and i'm tempted to split the cooper line myself for a shower head. The instructions i've got is from video, looks easy enough

http://www.thisoldhouse.com/toh/vide...632426,00.html


however before diving in.. is this something many fellow DIY-ers have done?


additionally, i'm looking to draw water from the main pipes coming out of the hearer, (3/4) and was wondering how big should my split be for a shower?

thanks



edit: to add, one of my concerns is that the line i tap is right next to the floor joist, since it's a slow ceiling basement, i'll need to solder right next to the joist and drill holes to have the pipes run though, i'm a little scared of having a torch next to that much wood.. that's all.

Pedro----Soldering copper is not to difficult for most DIYers. Practice a bit first.

In the areas where burning down the house is a likely hood---consider using a Sharkbite fitting--

They are expensive but so is burning down the house--

Use metal to shield the wood from scorching---I find that electric box covers make handy,cheap shields---they have handy holes for temporarily screwing into the studs.

Oaty Easy Flow solder and Oaty paste flux (Red can) are my favorites.

I also use MAP gas because it heats the pipes faster and gets the job done faster .

----Ask away----lots of members have learned this skill---others will offer their experiences to you---Mike---

thanks for the confidence boost.

now the real questions, i have a main 3/4 that's running out of the boiler that's feeding the entire house. i'm looking to connect a toilet and a shower on the same line after a split. so

1. how large should my line be for the split?
2. how large should the line be for the toilet and shower after they split?
3. potentiall i want to add a faucet for a small bar, does that change 1 and 2?

thanks

Use a 3/4x3/4x1/2 T---1/2 inch will supply a typical bathroom---Multiple head shower mixers require 3/4"

If you are using a standard shower mixer valve then 1/2 inch is fine.
