Moving The Sink

[whizbang102000]

Hi Gents

I am relocating the kitchen sink and wondered if there would be any issues with placing a 90 degree elbow out from the waste at floor level and running this along 600mm under the kitchen cabinets with another 90 degree elbow up into the new sink location

I am thinking about back flow etc

Any ideas or comments welcome

I'de be more worried about it blocking up , how long a run is it , can you make it a shorter run at 90 deg and then at 45 deg to the new sink ?

It should be ok to do what you want to do, but can you possibly use a P trap and just run a horizontal above the kicker/shelf?

Once I do the right angle out of the floor there will be a horizontal running 600mm and then another right angle going up into the s bend

I'm unable to run it at a 45 degree due the the type of cupboards. I'm thinking I should have enough volume in the pipework from the sink to the first elbow which may prevent any serious chocking.

Then I would suggest you use 90 deg bends that have screw off ports on the back to give some axcess if it does clog up

Good suggestion, I think this will be a suck it and see excercise but will run with the screw off ports on the back just in case it blocks.

Thanks guys

It would not be good if they block, but it would be highly unlikely. Our 57 year old kitchen sink galvanised steel pipe waste was just replaced, and it was 2/3 blocked, but still worked. I only saw the restriction where it was cut in half. I would like to think a modern 50mm PVC would last similar, if not more years.
