Can my sink be 4" to the side of my drain?

Question

I'm installing a new double vanity and the drain pipe (which is coming from the wall) is about 4" to the right of where the sink drain hole is. Is this a problem? What parts do I need?

Answer 1

You can use a tubular offset. It can be chrome or pvc.
You can cut this in half and use it where you come out of the wall.

Hope it helps.

This offset isnt a problem. You have many options to route the drain. First, from the bowl of the sink you will have a tail piece which will enter a "P" Trap. We know you need a "p" trap because you indicated that you waste water will flow out the wall ( an "S" trap that would exit through the floor ) The "P" trap kit will include a "J" Bend and a horizontal waste arm that is intended to connect to the pipe in your wall. Heres where you modification will occur.

A few things to know:
1.) you can use thin wall pvc or chromed metal interchangibly. The fittings are the same. I suggest PVC due to its better tolerance of the chemicals we use and its duribility over the metal.

2.) the nuts that connect the peices are called slip joint nuts and they are responsible for pushing the slip joint washers into the joints with pressure to make everything seal up. (NO teflon tape or pipe dope necessary.)

3.) All fittings should reach a pint of water tight just by hand tightening plus 1/4 turn with a pipe wrench or pair of channel locks

4.) the connector at the pipe in the wall should be 1.5 inch male pipe thread (if your wall waste pipes are PVC (DWV = drain waste and vent) the adapter is called a "marvell adapter" This is the peice that accepts the watse arm slipping into it and having a slip joint nut tighened onto it.

5.) The metal or chrome pipes can be cut with a hack saw or tubing cutter (of sufficient diameter)

6.) a trap is always necessary to hold a small amount of water in it so as to prevent sewage gasses from back entering the living spaces of the house. DO NOT BYPASS A TRAP!

7.) general rule alyays said 1 1/4 inch pipes for bathrooms and 1 1/2" pipes for kitchen, I say get the 1 1/2 pipe "p" trap kit that will accecpt your 1 1/4 inch tail peice from the bathroom sink drain then stick to the 1 1/2 inche pipe from there to the wall. You'll have a wider selecting of fittings and angels in 1 1/2 inch pipe, and better flow of the water.

So my suggestions are:

to stay away of the flex piping as it restricts water flow especially on horizontal runs like were you will need to use it.

to use thin wall pvc instead of chromed metal

to cut the waste arm provided with the "P" trap kit and uses 2 45 degree couplers to offset to the drain hole.

to always but a few extra slipjoint nuts and washers, as well as one 12 or 16 inch entension tube. and Use as needed to fit the trap to the proper height and distance from the wall.

to START ASSEMBLY AT THE TAILPEICE AND FIT AND CUT AND JOIN TOWARDS THE WALL FITTING. This is important as it will allow you to keep your trap high and out the way so as not to sacrifice too much of your vanities storage space.

Many hardware stores sell flexible drain piping. It looks like corrugated plastic piping. You can use this to connect the the drain pipe to the sink drain. There is a limit to how long the flexible tubing can be, but it's often an easier solution that finding a dozen of straight connnectors that will do the same.

Answer 4

Standard trap deviation is 3 inches, you need 1 45 degree el to angle the drain to line up, it is easy, unless you don't have the room for an extra fitting, if that's the case, run the pipe just past the center and swing the trap back to the drain hole. There are many mechanical fittings you can use to rearrange the pipe[ no-hub coupling or fernco].

Answer 5

There are many thing you can do with lining up the drain, think of it like a puzzle, but only with round pipes. Go to the hardware store and picture in your head how this drains looks at home and figure out what pipes are needed to complete the installation. Most times extra pieces of pipe are good to buy incase you need another duplicate piece and would save time from running back and forth to the store.

Answer 6

you're able to desire to continuously run water whilst working the disposal, provided that this helps lubricate the blades and flushes the chopped debris down the drain. that could be a risk that the countless blades are misaligned or something, and consequently they are interfering whilst that is working. i might propose do no longer use the disposal until you have had a expert look at it - once you're renting, call your landlord; in case you own, call a plumber.

Answer 7

You can set your sink across the room if you want. This just means longer drain lines and or re-routing. There is no problem doing this.

Answer 8

Yes you can do that . the plumber can offset the pipes to hit the drain where ever it is .

Answer 9

yes you can buy flex hoses for that purpose at any hardware store

Answer 10

Strangely enought that can work if the plumber really new what he/she was doing.
