moving kitchen pipework

apmac

Hi all,
We have recently moved house and are hoping to redo the kitchen. Currently our kitchen overlooks the garden and our dining room is at the front of the house. Our plan has always been to knock down the walls between the rooms, bring the kitchen to the front of the house and replace the current kitchen window with french doors leading to the garden(from what will be the new dining/family area). Changing the layout will be more expensive, partly as the boiler will need to be moved from current kitchen to the garage, but it will make the house work much better for us than currently.

Anyway, we haven't had a plumber/heating engineer round yet to quote (don't know anyone/no recommendations/sticking our heads in sand in case we can't afford it) but we are starting to get concerned about how the pipes can/will be relocated for the sink & d/w. All of the wastes in the house seem to be on the back wall but we will be needing our sink etc on the front wall of the house - 7m away. The problem is the sub floor seems to be not much more than a foot deep.
Does anyone know if this is doable?? We will be getting the professionals in for advice but I'd like an idea of what is feasible first so we don't waste their time. Thanks for any replies!

Without an idea of how your house/garage and drains are arranged it's impossible to say. Don't understand the bit about the sub floor - is this a concrete floor? How do you know how deep it is?

It's impossible to answer you query on this forum. You really need someone to look at it.

If you identify your location, somebody maybe able to recommend a tradesman.

We do try to be helpful on here. But unfortunately, we are not able to guess the layout of your drains and plumbing arrangements.
You will have to get someone to look at the job and give you a quote, or to say whether the changes you want are at least feasible.
Any quote you may receive is just that, a quote, so you are not committing to anything.

I think the OP means the void below the suspended floors in which case 1 foot of drop would be perfectly adequate if they can get across the house and out of the other side.;);)
Have to say I wouldn't consider it good practice though

A foot drop may well put the exit point below ground level.... Just another thought to add to the mix!

Exactly, that's what I meant when I said "...if you can get out of the other side", ;)

Hi everyone, thanks for your help. Looks like I used the wrong terminology. When I said 'subfloor' I did indeed mean the void under the floorboards.(is the subfloor the ground at the bottom of this space then?) The ground level at the back of the house is around 50cm below floor level (we are having to build a deck & steps outside our new french doors) so it sounds like this should be plenty.
Cyclonebri - thanks for your help - can I ask why it wouldn't be good practice? Is it just to have such a long waste pipe over a shallow drop?
We are also planning on moving our washing machine into the garage(through the wall), which has a concrete floor so nothing simple here!

Depending on your layout, is there any way you can run the drainage out into your garage, along it's wall to the back of the property?

No, the drop is fine, it's simply inaccessible once the house is finished;);)

Run the waste as a 4 inch soil pipe, these are always run under the building so would be fine.
