Do you need special plumbing for a double sink?
A double vanity can offer a “his” and “hers” sink. In most cases, you can easily adapt the supply and drain pipes to accommodate two sinks, using tee fittings, special valves, extension pipes and hoses. You may have to vent each sink separately, though, depending on your local plumbing codes.
It is perfectly fine to have (2) “P” traps, one on eash sink of a (2) sink setup. As long as the “P” traps are not Double Trapped ( more than one trap serving a fixture ) then it is fine as long as the weir is sized correctly.
Can you turn a single sink vanity into a double?
It’s entirely possible to replace a single sink with a double sink, although it requires a bit of work and money. Many of them also come with cabinets over the sink along with a mirror. Vanities come in a variety of shapes and sizes to fit into any bathroom.
Does a double vanity add value?
Double vanities also add value to your home. While one sink is typical and essential, two sinks make your home more desirable and attractive to potential buyers. Often, the choice to buy one home over another is how practical the bathroom is; a double vanity definitely adds to that.

Why is s trap illegal?
Back to “S” traps – The reason “S” traps aren’t allowed is because they have the potential to suck, or ‘siphon’, water out of the trap as the water flows down the drain. On a properly installed “P” trap, there is a vent at the same place the drain turns downwards, which breaks the siphon.
Can P-trap installed backwards?
The outlet end of the trap pipe should be lower than the inlet when installed properly. The example shown has it backward, which creates a trap seal more than 4” and makes the drain more likely to clog—and that’s a long explanation for why a backwards trap is a bad thing.

Why are there two drains under my sink?
Re: Single Bowl Sink but Two Disposal Lines The DW really needs to be hooked up to an air gap, this prevents ingestion back into the DW of sewage if/when the drain backs up. You can either use an above sink air gap if you’ve got a hole for it, or you can leave it under the sink as high as possible.
