Please repost your floor plan.

Jake The Wonderdog Oh my gosh! I hope that's not the case!!! :( I can't believe they didn't account for this. That laundry room has been there before we started anything.

IMO it could have been solved by moving the laundry to the west side since you have your mechanical in that space anyway you even have laundry sinks there . Yes it should have been discussed not sure how to address it now without major work

Sometimes things go sideways. Some locales will allow washer discharge into a dry well, it's worth it to check. To avoid the issues that will come with cutting the floor (floor cracking which can allow water intrusion) move the W&D into the mechanical room. You're entitled to a large contractor discount for this oversight.

What is the drainage plan for the future kitchen? Was any piping built into the foundation for that sink? If so, you could tie into that. If not, then you aren't getting that sink either.

Would something like this work to help push the grey water to the septic tank? https://www.saniflo.ca/en/installing-an-additional-bathroom/96-sanivite.html

catlady999 Yes! That drain is there!

You may be able to tie into that. Code requires 2" drain for the laundry.... tell contractor to figure it out. If kitchen is 1 1/2" tell contractor to buy the inspector a beer. The 2" requirement was from when we had top loading machines with 10 gal of water in them.

Jake The Wonderdog I expect a solution from him by the end of the day. It better not be something insane. Im assuming he should be able to run the pipe straight down then under the stairs and then to that drain pipe.

What is the black pipe sticking up next to the ladder? (I'm guessing that the pipe with the red cap is for the sink.)

Could that have been planned as the laundry drain?

It's awfully large for that. But it might be for a toilet, except that it is under the stairs...

The large pipe you see under the stairs is actually some new thing they have to do for code. Something about gases being released from the soil in the future potentially? It’s required for all new builds.

Radon? There's more to it than that.

It maybe for detering radon. EPA recommends a gas-tight pipe venting from gravel level thru the building to the roof.

What did the builder say about the laundry drain?

catlady999 Radon! That was it but it just needs to be capped so that it is there for the future.

Laundry will drain to the pipe where the rough in for the kitchen sink would be. The island above will drain to there as well.

weedmeister Yes radon. What more could there be? Is there something I'm missing? Inspections have been complete with no concerns about the radon pipe.

Joanna - so glad that this problem could be solved without tearing up the foundation!

If possible, it would be better to extend the radon pipe to the roof now while your framing is exposed than to try and retrofit after the walls are all up.

What I meant was that there is more to a radon abatement system than just a pipe in the slab. Usually it requires positive (ie, a fan) ventilation to the outside above the roof. Also, the 'drain pit' may need to be part of it. And if you're on a well, the well water has to have the radon removed. All depends on local code.

Radon has to vent to the utside and should be done now what would be the reason for waiting for later.

catlady999weedmeisterPatricia Colwell Consulting From what I am reading online for Ontario code it is not required to vent it out however I can understand why we should do it now regardless. I have to talk to the builder about this.

weedmeister We are on well and the well water was tested this year by both of our neighbours who are about a quarter of an acer away from us and are on well. Both tests came back with zero concerns.

I don't think radon, being a gas, is something that is checked by water testing.

weedmeister Sorry I misunderstood your comment above then. :/

Is there a 1st floor plan? Can the laundry room be moved to the other side of the house? Is there a 1st floor plan?

Yes, radon can be in drinking water from wells. Per the EPA

GN Builders L.L.C This is a high rise bungalow so the other side of the house is the bedrooms. No space for laundry except our walk in closet but we don't want to put our laundry in our walk in closet.
