Moving sewer stack - $2700?

[paperfist]

2.5 inch pipes or smaller need 1/4 inch. 3 to 6 inch is pitched at 1/8. Might be different outside my area though...

Thanks for clearing that up. I think that's a universal code as water follows the laws of physics.

I guess plumbing on the moon might be a little different.

In reading your post it seems like you were saying you wanted to keep the connection from the stack you are going to cut within the space of the floor joists as it makes its way to the other sewer stack.

Also if I recall from my plumbing days the plumbing fixtures need to have a vent within 6'.

Well this post is specifically about the drain. I'm still exploring options for the sewer stack. Regardless if we move the stack or not, I'd really like to reposition the drain.

If a plumber said it was doable, what are you asking?

Did he say there were any concerns with putting those sharp bends into the pipe? No issues clearing the pipe if it happens to get clogged?

The location of the drain will be influence by its maximum distance from the vent (usually the stack). The size of the pipe used for the drain also influences this. See this for explanation http://i.stack.imgur.com/kHyFV.png

Well, it's a straight run from the original drain to where the new drain would be. We'd just excavate the concrete and splice a new drain in 3ft closer to the stack. No new bends or anything for the drain. Again.. talking about the floor drain.

If we don't move the sewer stack by the stairs, and just move the drain, we're actually moving the drain closer to the stack by about 3ft.

Ok, I was talking about the sewer stack ... you know, the question that you asked and the video link you posted just a couple of hours ago.

 

[TechBoyJK]

Yes, sorry. Yea, the sewer stack was the OP. I wanted to be clear in that the recent posts were about the drain near the stack. I didn't want to create another post for it.

Hi Guys,

Wife greenlight the $2700 expense to have the sewer stack moved. Once we got more done in the basement and she saw how well things were coming together, and she realized the only thing keeping me from putting the home theater downstairs and away from the baby was moving the sewer stack.. once she realized all this she asked me to have it done asap.

Dilemma here is that I want other plumbing stuff done, and if I could get the concrete done for much less ($1700 of the $2700 bid is excavating and backfilling concrete), I could use the saved money to have some of the other stuff done in the same project.

The plumber is one of the better rated companies in the area, and they did a bunch of the work on our house for the seller who rehabbed it. So they're already very familiar with the property. When I was getting the bid for the sewer stack, the plumber actually knew all about my house and the work that was done.

The wife also wants it done asap and already just asked me if I contacted the plumber to schedule the work. I'm telling her to hold off because if I can figure out how to save some money I want the plumber to do more work.

Thoughts?

You can do the concrete yourself if you want. It's really not that hard.

TBH the hardest part is breaking up the concrete, I'd hire that part out and do the rest myself. Though it is an adventure to try it, but it's something you probably only want to do once. haha. You mentioned a baby though... you won't want the baby to be in the house when that gets done. Will be very loud.

Adding the new concrete is not that big of a job though. So I'd do that. Always get more than what you think you'll need. #LFMF

Meh. It's good exercise. Get a diamond blade for your circular saw and take out your aggression with a sledge hammer. Then get some deadlifting in moving the pieces. I'd argue disposal is the hardest part.

 

[TechBoyJK]

I should add that my right shoulder is screwed up so I'm not swinging a sledge hammer or doing any heavy lifting anytime soon.

I'd have to ask my dad or hire someone else to do it.

 

[TechBoyJK]

I'm thinking about having them do the excavation, but leave the spoils and backfill to me. I have a friend who would help me clean up, and my dad and I could pour the concrete.

 

[TechBoyJK]

Wife convinced me to just back off doing the project myself and let her pay to have it all done. She wants it done asap, so she doesn't want me pecking at it over a few weekends. $2700 it is...

Sounds like a decent quote. $2700 for all that work is really not bad at all. Take it slow with your house, seems like you are doing major remodeling every month!

I've pretty much been doing various projects since we moved in.

One of the things keeping me from being able to frame off my music room is that I couldn't build the wall that separates the room from the rest of the basement until the sewer stack was moved. The sewer stack is being moved to a spot that will eventually be walled off. I didn't want to build the wall then have to tear it back out to fit in the sewer stack. Plus, We have a big sectional couch that we want to put down there, and the sewer stack is in the way. So the sewer stack was literally a blocker.

wooooo plumber is moving the stack today. so far so good.

Pic from when we first moved in.

We scraped off all the remaining tile, used a floor sander to take up remaining adhesive and smooth the floor out, sealed any cracks, then put Valspar Concrete Sealant down on the entire floor to make it look nice. I also painted the sewer stack white using some leftover paint.

This is a pic of 3 images. Before, after, and photoshopped to cover the hole. The plumbing still needs to be inspected by the county before the floor can be patched.

Rest are pics of the new stack

If I remember correctly, you were going to pipe one stack into the other and eliminate one of them? Looks good. Nice clean install. Is the stack that goes up into the rest of the house still cast iron?

It ended up not being possible to route the 2nd floor stack over to the primary one. So we had to use the original plan of moving it closer to the stairs.

The upper leg of the 2nd floor stack was pvc.. so it's all pvc now.
