At the moment my kitchen sink is on a wall where my garage is on the other side of it.
i want to move the sink to under the window that over looks the back garden, but the SVP is in the opposite corner back on the wall where the sink is at the moment.
I could have had sink waste with a reasonable fall to the pipe, but there's an outside door between where i want the sink and the SVP. I can't have the waste go below this and still have a fall to the pipe.
what options do i have?
send the waste outside and hope there is a drain under my patio?
can you put a macerator on a kitchen sink to send the waste down microbore? will it annoy the fuck out of me if it kicks into life each time i use the sink?

This is what we did, however as we had the patio up we channeled the pipe to the drain under the paving.

I'm really not sure there is one out there.
Certainly no manhole/drain covers.
I could lift a few slabs and dig down on the offchance i guess, but don't want to ruin the patio, lol.

how long a run of waste can you get from the sink to where the fall will end under the door, and how far is it then from the door to the SVP?

It'd be about 1.5m to the door, then about 2.5-3m from threshold height to SVP

it would be ok if you could get a steep fall from the sink to the door, then if you could get even just a tad of a fall after that, highly unlikely though if its going uner a door

oh, it will have some head from the sink trap height to push the water along to the svp, right?
or not enough pressure?

as long as it isnt falling back it should be ok, the smallest of falls will do, just make it as steep as you can till it levels off to get it moving as quick as possible
