Can I lower kitchen waste line below the entry to stack?

[kingjude]

Can I lower the kitchen pvc waste pipe line to be as close to the floor as possible, still going at a slope, and then back up into the end of the line into the main waste column / stack thing by using a p-trap or any other layout?

or if anyone can recommend a way for me to have the drawer in between the columns?

I also thought about moving or rerouting the hot and cold water pipes over close to right column where the waste line ends but I wouldn't know how to do that and I think I need a plumber for that but I am confident in doing the waste line.



In between the two columns I was going to put a 1000mm kitchen base cabinet and put drawers in it. My issue is that the pipe will go across the cabinet and I would have to cut the cabinet and will be unable to have drawers.

Not a good idea. You will create a giant waterfilled trap, ideal for accumulating gunk and gunge, therefore a blockage looking to happen.

Water/gunk/gunge will accumulate in the pipework below the dotted line:

even if the slope is the same?

In a word NO!

It will cause a water filled trap and cause big problems in the future.

Charnwood has it spot on.........................well done counter boy.

any ideas then?

any help is much appreciated.

I was also thinking about using a 90 bend at the end of first column, putting line behind plaster wall, still at a slope and then another 90 bend towards the beginning of the second column and then straight into the stack?

 

[kingjude]

would this work? using 90 bends and putting line behind plaster wall? or just through it and still have access to the pipe if need be?

Is there a gulley outside?? if so is it soil or rainwater? or combined?

If I was doing it that way I'd do it with 45 degree bends, and preferably solvent weld.

And less of the 'counter boy', please.

What's this, a solid column?
