Soil stack question
 

How hard and expensive is it to move a soil stack. I have one approximately 1.5m from the front of the house (down the side) and wish to move it to the front when I put a garage on the end of the property.

I don't want to start the garage 2m from the front of the house as I feel it won't look right, and will add issues if I ever put a second storey on top of the garage.

On a side note, how hard and expensive is it to replace the sewerage pipe running down the side of the house from the soil stack, as I may need to put it deeper in the ground once I start excavating?

Thanks in advance

Not as easy as leaving it where it is ;)
You can have a foul drain passing through footings; it's allowed.
Might be a bit nasty having a stack in the new living room but not much bother in the garage surely? You could box it off with plywood if its an issue.
You can easily weather it where it exits the roof.
Get's done all the time.

Would rather it stay on the outside of the building, just in case I want to put a second storey on at some point!

They do have them inside you know :)
Sometimes it's better depending on what you need to connect to them.
I smell a living room ;)

Moving stack is not so hard. You'll need to dig up the ground over the drain.
Just connect to the drain further along bearing in mind that you will need a manhole/ inspection chamber (depends on how deep the drain is) wherever it changes direction. Surround the drain in clean chippings (the right kind; there's regulations) and back fill. You'l need to protect the drain if its under where vehicles go.
Biggest problem usually is reconnecting whatever there was originally connected to the stack where it was before.
You need to be able to rod all the straight runs through access points and each run has to 'run' so that the foul water drains away.
Theres regulations about how much 'run'.
Cant give much more advice without knowing what the exact set up is ...

I'll photograph the stack/area and doodle some diagrams, and put them up over the weekend.

Re: Soil stack question
 

Here all above ground drainage is inside to stop it freezing, and its not a problem, just either boxed in or hidden inside the wall.

Re: Soil stack question
 

Knowing where the drain that the stack leads to would be useful..

At last!
Somewhere thats colder than us! :)

Re: Soil stack question
 

Most new builds now are inner soil stacks, theres nothing wrong with it, as skeetly said leave where it is if poss.
Getting the correct run is crucial, our building inspectors are quite lenient, i know there are regs about runs and access / rodding points but they will let you get away with some as long as 90% is ok.
I find drainage easy, i hate the digging to expose the existing, cant stand digging, especially clay soil.

I dont know we are at +4 at the moment. I still cant get my bike out though as we have at least 75 mm of ice on the side roads. Looking forward to April!

Re: Soil stack question
 

The soil stack enters the ground at the side of the house and the runs for almost the entire length of my 100ft garden to the main sewer, all of which is downhill,

Re: Soil stack question
 

I already have a rodding point half way down my garden. This was put in 2 years ago by the previous owner.

I want to move the stack as I feel it would add more value to have the garage level with the front of the house than if I stepped it back 2 meters.

Most of the ground beside my house will need to be dug up when I build my garage anyway, so I'm thinking about just renewing the pipe while I'm there and moving the soil stack forwards.

You'd hate digging here as it's mostly clay soil!

Re: Soil stack question
 

Just a thought, are you intending to move the toilet as well as the stack? Or are you just going to run a 4" pipe 2 metres along the wall?

Re: Soil stack question
 

Wont be moving the toilets, just the soil stack. Not sure on the regs side of things if your allowed to slope/kink a soil stack or if they have to be perfectly vertical. One of my toilets would be further than 2 metres away from the stack if I move it, but I wasn't sure if I could angle the soil stack, or indeed the pipe from the soil stack to the toilet.

Everything you need and have to know:

I've never felt that any of these regulations are particularly over the top.
If you find yourself unable to do it like it says in the reg's than chances are it will bite you on the ar*e later on.

HTH.

Re: Soil stack question
 

+1 for leaving it where it is and boxing it in if you can.

4 inch pipe and brackets, boxed in will take next to nothing out of the size of the room.
For the cost of materials, time and effort, it's really not worth the hastle in the long run.

Re: Soil stack question
 

It will be outside the house, going to inside the garage, this will be the awkward bit. I'm not building a second storey yet, just a garage. I would rather move it if I can.

That may as well be written in German! Do you have a gobbledegook to layman translator? lol

Re: Soil stack question
 

Here's the pic of the soils stack. I want it moved to the front of the house. The drain runs down the side of the building, between the building and the car.

Re: Soil stack question
 

if you make a double extension (second floor as well) you could run the pipe from the toilet under the floor of the extension and move the stack to the outside of the extension which would save having to route the pipe from the toilet any other way since you cant drill a 4" hole for it through joists (if there in your way for running it to the front of the house) and the stack stays "hidden" down the side of the house as well. This is only possible if the width of the extension is larger than the length.

The extra building work is easy enough even if you dont plan on building in there for few years to save building the garage waterproofing the roof, then taking it off when you plan on putting the second floor in. its all can be done cheaply if you give me a bed to sleep in while i do it, and find a good bricky, roofer and plummer. Im free in Sept and can do all the other work (or know a guy willing to travel that far).

Edit: looking at them pics it is possible my way and i can move the soil pips not the water tho i always leave them leaky.

Re: Soil stack question
 

All those joints are around about the roof level then?

Flat roof?

If I was building your garage I would still go with leaving it where it is.
Remove the section containing the 2 branches from the 2 toilets.
You can reduce the slope of those two pipes from the toilets so that they enter the stack higher up.
Use one of these:

Hopefully higher then where it passes through the flat roof.
It's pretty trivial to form a weatehr tight seal where a stack pipe passes through a flat roof.

The whole lot can be boxed off easily afterwards.

If yoou move it to the front you'll have far more work to do altering those junctions in addition to the expense of moving the stack.
I'd say the pipe running from those 2 toilets would end up lower than the roof level right at the corner and you'd have another mess to sort out there.
I really would leave it where it is.

Re: Soil stack question
 

I agree with skeetly, seems straight forward to me to leave it, mono pitch roof on garage, you could hide the lot in there.
