Existing drain line to low for new vanity

[biglott]

Hello, I'm installing a new vanity and the drain pipe is too low and out of line with the p trap.
How would I go about fixing this? If I raised the drain line up 3" - 4'' it would still be out of line.
Thanks

Can you lengthen the pipe from the sink to the trap??????

No, The green is the bottom of cabinet. In order not to cut the cabinet, I need to move my drain line up. But still I will be off center with the drain line from the wall. Thisdrain line ties into old cast iron line that is under concrete.

[/QUOTE without reworking piping behind the wall,unless in you think it's too old to leave, best way would be to cut the shelf, if the fittingin the wall is a tapped ty (female thread)
State fresh there with glued pvc joints and you will get your angle

Move the line up if that is what you have planned. If the trap isn't straight on to your pipe just swing the
trap either right or left. There was a thread not to long ago for the same problem and he notched out
the bottom of the cabinet and it didn't turn out to bad. Lot easier that cutting the pipe out in the wall;.
Check it out as he took pictures.

Most drains end up needing a little swing. Unless you have everything drawn out ahead if time and dimensions for everything this is common.

It also seems to be common that people are buying vanities that don't fit what they have, so they need modified. Or you can dig into your wall.

As others have said, it might be easier to notch the bottom of the vanity shelf, but it all depends on what you want to do. It looks like if you turn the bend part of the trap to the left a bit you can turn the straight piece to line up with the pipe in the wall (which I know was already suggested).

Just thinking a little more. Depending on your piping in the wall it may be extremely difficult to change it and vent the lav properly.

Currently the drain pipe is 18" center of finished floor, I think I can raised it to 22. Will I need to move my water lines up also? Thanks

The higher everything is the more its hidden and out of the way, on the other hand, it gets harder to work on if it's tucked up behind things. Also if you change vanities down the road it can mess with the drainage, if you go too high. 18" is pretty standard. It's your choice. It doesn't look the like water needs moved, but your choice. You might need longer supply lines if you leave them low.

If your new valves don't hit the bottom of the vanity then you shouldn't have to mess with them.
