One sink to two conversion (piping question)

I'm doing a complete bathroom remodel and I'm switching from one sink to two. I'm not sure how the piping should be routed. Both the drain pipes and water supply lines as well. I know the Rough in measuraments, I'm looking for advice on how all the piping should come together. Thanks in advance.

One sink to two conversion

Since you haven't done your drains or supply yet, then you should be able to give each sink its own drain and supply lines. Drains should be 1 1/2" from stub out to the main drain, and you should use 1/2" supply lines from your main supply.

one sink to two conversion

Thanks for the info, but here is my question. Do I install separate supply lines to each sink and run them to the 3/4 pipe ( to & from the hot water heater ) OR do I run a tee off of one set of the 1/2 lines and Then connect them to the 3/4 pipe ( to and from the hot water heater ) I'm aware that the supply line is 1/2 inch. When I look in my "how to" book, It shows a basic " rough in" drawing of supply lines for one sink but not for two sinks. Also, will it make a difference in water pressure by adding a double sink? Thanks again for your help.

Washer Sewer Smell

M

Michelle649 on Jan 08, 2006

Hi, Last weekend we has a sewer back up in our basement because of tree roots in the main line. They were cleaned out an my husband has cleaned the sewer with Javex many times. Our washer is upstairs with the drain going into the sewer. There is a smell in the washer that we can't get rid of. We have put Javex down the drain and still smells. Seems to get worse when we do laundry. Are we missing something that we should be doing? Any help would be great! Michelle

connecting brass to steel

I'm replacing the backyard sprinkler valves to a house I recently purchased. The outlet for the old valves are connected to galvanized pipe which are set in concrete. Somewhere under the concrete, these galvanized pipes connect to PVC pipe which runs underground in the backyard. I would like to connect brass sprinkler valves to the galvanized pipe. I know that there are electrolysis issues when connecting copper to steel. Are there similar issues when connecting brass to steel? I plan to install a union between the brass valve and the galvanized pipe. Do I need to use a dielectric union or can I use a regular union?
