The distance is not really important as extra piping and fittings can be used, but making sure you have a good gradient is of the utmost importance
The overflow is built into the sink, it is not part of the drain. If there is no overflow, you can not add it.
That would depend on where the floor drain was in relation to the sink. If it is the drain for an existing sink it may be too far out from the wall. There is no way to know without measuring. The pedestal may have a hole in the bottom of it that may be big enough for the drain or not. Depends on the manufacturer. If you can get it to line up somehow, there is a trap that drains out the floor instead of the wall.
A new sink with a spray device like a small handheld shower, a new drain extension and a water supply. Best near an existing sink or bath. -I have installed quite a few of these for home hairdressers. About 5-6 hours labour depending on existing setup.
As long as the drain basket for the disposal will fit the drain hole in the sink, there shouldn't be a problem
That would depend on the height of the drain and how deep the sink is. As long as the drain is lower than the bottom of the sink, it should be fine.
The drain pipe should have a vent that goes up where the sink drain goes into it. That is where it vents. Sinks drain because there is nothing causing a vacuum when the water leaves the sink.
Water doesn't run up hill. There will be 2 inches of water in the sink at all times. Cut out the wall, install a new T and either remove the old one or cap it off.
the sink drain is prob.in the wall.you would have to get a wall mount commode,or install drain in floor and plug drain in wallAnswerYou also need a 3 or 4 inch drainpipe.Ans 3 - You can do this if you fit a new 3" drain to the main pipe and run it to a toilet flange where the sink is.
It is not excessively difficult to add a second sink. Make sure that there is enough room for the second sink. If you install the second sink next to the existing one, installing T-fittings to existing plumbing is a good idea. anonymous@oola.com
sounds like you are going to need to install a sump for the sink to drain into and then you put a sump pump at the bottom and connect it into the houses main line.
Yes, it is done all the time
