Browse Forums Building A New House 1 Mar 28, 2022 10:37 pm Hi I notice my builder wants to connect the sewer pipe from the upper-level ensuite externally. Although it's on the side of the house, will not be visible and will look like a downpipe what are the downside of it? Would summer heat, heating the pipe cause order? The sewer will run below the soffit, turn down on the side of the wall down to the sewer.

Yeah that I understand but was under the impression it doesn't go straight into the same pipe down to the sewer? Thought toilet waste goes in its own pipe first down to a point before going into the main sewer pipe. That is just how I see it in my head as I would assume if it all went to the same pipe in the room you would have a foul smell coming from the drains.

That actually makes a lot more sense then running two separate pipes from every bathroom down to the main line. So is it then a normal thing to have this sewer pipe going out externally? Re: Sewer Pipe - external connection 7Mar 29, 2022 10:03 am Beetroot_Juice, The pipe is 100mm upvc, so it's stabilised against UV damage by the sun. all the fixtures (toilet, handbasin, shower etc) have a trap water seal, so you won't get fumes venting back into your bathroom. Does this builder have this house on display? if so go and have a look on how he addressed the waste on his display! If it's not exposed on the display them him to rectify it the same as the display. You should also look at you elevation drawings to see if it is shown in the drawings, I am guessing it won't, then them him to rectify it. My guess is that they forgot to bring a drainage point through the slab and now have to go external to connect to the drains. Separate to the drain issue. Why is there no wrap on the frame? The upper storey has scaffold but not wrap and the frame is showing exposure. But the top brick for the lower floor, you can see back through the gap between the brick and the underside of the top plate and it appears that wrap isn't on the lower floor either? Your builder is also going to have a hell of a job achieving an acceptable finish to the bricks if all the mortar is like that, Off white mortar on a dark brick left for awhile doesn't end with a good finish.

That actually makes a lot more sense then running two separate pipes from every bathroom down to the main line. So is it then a normal thing to have this sewer pipe going out externally? Yep that's what the s bends and p traps do, also the vent pipes (aka stink pipes). Whether its normal to exit a sewer line out like that, I don't know, though I've lived in a house where this ran down the inside of a wall to go through a slab, and the pipe broke from something, there was sewerage in the walls. Was a rental so not my problem, but you can imagine the headache this caused everyone. Dark matter scientist, can breathe underwater, mind reader and can freeze matter just by willing it.

Thank you for your input. Your guess is 100% on as the builder forgot about the drain when pouring the slab. The sewer pipe will run on the side on top of the water tank down to the sewer so there will not be any major visual impact. Re, wrapping was questioned and was told it is not required by the builder! According to my BAISX /Nathers report, there is insulation on all external walls and the roof. Is there a guide / standard that I can refer to ?

Is there a guide / standard that I can refer to ? in your basix report, there will be a column on the far right of sections titled "external wall type" titled "reflective wall wrap" and you will be able to see if they used it in the calculations. If it says "yes" then it should be installed. Unsure if its mandatory, maybe somone more knowledgable can comment.

Re: Sewer Pipe - external connection 11Jan 11, 2023 2:44 pm Hi there, i have had my builder also so same. Forget sewerage in slab so for 1x upstairs bathroom had to go external. I have 2x upstairs bathrooms but other connects to one in slab in another part of house. For this forgotten connection I have two drains in upstairs bathroom going to a toilet that then connects to an external pipe down into the sewerage line. There is no vent though. That extenral pipe connects into another sewerage line at ground level (the one not forgotten )that makes its way to sewer. The other sewerage line for other toilets has a vent. Should I have had another vent of this system or is this one enough. Ie there is "one vent in the system " . Reason i ask is noticed odd smell in summer. Ran water through system this morning but odd smell still remains. Re: Sewer Pipe - external connection 12Jan 11, 2023 3:19 pm dbo2809 Hi there, i have had my builder also so same.

Re: Sewer Pipe - external connection 13Jan 11, 2023 3:39 pm i guess my question is does all toilets need a vent or as long as one part of system has vent ( not matter where it is) it should be ok.. yes it does have smell. builder says he will send plumber but you never know when that person may come.
