I have a relatively modern energy star rated Carrier furnace/AC installed in an unfinished basement. I am thinking about finishing the basement and have had a few contractors in for quotes. One...

A quick question regarding the placement of the evaporator coils placement on top of a residential furnace. Within the plenum above the furnace, is there supposed to be a gap between the coil and the...

I'm running a primer line from my laundry sink to a p-trap in my basement floor slab and I have a quick question: Is there a preferred placement for this line and should I run a 2nd (backup?) line in...

Very true. My laundry sink/drain will be plumbed as shown in one of Terry's posts. The 2" vents will tie together and then head up to the attic where they'll connect to an existing 3" vent. My only...

No harm done as it is mostly held together with bits of tape :p My concern was how tight that radius was compared to my original drawing and that I couldn't get the vent to run anything greater than...

I've finished excavating and have laid out my basement drain and laundry (dry-fit) and I was wondering if anyone has any comments. It is more-or-less what I sketched out in a different thread, but I...

The fellow at the local plumbing shop suggested I use a 4" flexible coupling (apparently different than a no-hub coupling). The green pipe, he insists, is SDR-35 and is used by the...

My other option is to get a pair of 3" I.D. bushings, some 4" sch40 pipe and splice in a sch40 4x4x3 wye directly. This will use 2 bushings instead of one and effectively reduces the I.D. of the main...

My mistake when drawing. I've also added a T-cleanout where the 2" laundry drain line meets the slab. The perspective of the floor drain vent is also a little off.

Thanks HJ. As I've said before, they cut every corner they could when they built this place. If you think the plumbing looks suspect, you should have seen some of the electrical. I do wonder how they...

Hackney, thanks for that. I put my calipers on that broken bit of green pipe and its thickness is 0.179" (i.e. schedule 30). This just keeps on getting more and more fun. Will it really matter if I'm...

I figured that there must be a reason that it changes above and below the slab. Seems strange.

I've now located the waste line under my slab.

Above the concrete, all the plumbing waste/vent lines are ABS, while below ground they are green/white PVC. My plan is to wye into the 15" long...

My plan was to use epoxy for the floor. It will remain unfinished for the moment. I could tile it, but it wasn't my plan.

Thanks. That is what I feared. Off to rent a propper demo hammer.

It's a residential basement with a pour between 4" and 6" thick and more rock than I expected. Plans show it is non-structural but I could put my truck on it. Either way, it is too much for my little...

I'm in the process of adding a basement floor drain and I've found the basement pour quite excessive which is making cutting and jackhammering a pain. I need to re-pitch the floor to the new drain...

Anyone have any thoughts on my 2nd attempt?

Can I ask the purpose of the poly? If your basement floor is allowing water up from beneath then you're likely going to have issues no matter what you do (IMHO).

I use ship-lapped, rigid foam...

Thanks Tom.

Indeed, I've drawn the 2" vent for the drain as running under the concrete (above the drain lines) and then up the wall to 48" and then connecting with the other vent(s). I assumed if...

As described in my other thread, I'm relocating the laundry and floor drain in my basement. It is worth mentioning that the location of the floor drain is between the tankless HW and the laundry. The...

I'm contemplating my options for locating a 2" vent in my basement which will serve my relocated laundry and floor drain. I was talking with a fellow at the local (independent) plumbing store and he...

Thanks, the problem is that it isn't a straight, vertical run to my attic. Will need one major jog as the roof level is split. Oh, and I hate distrubing all that blown insulation up there.

Thanks for the quick reply dlarrivee! Indeed, the 'stack' is 3" and only contains the toilet with the one sink connection. It directly enters the main sewage line beneath the slab. I have yet to...

Can anyone advise when a toilet vent isn't required in Ontario? I have a small 2 piece bathroom on the mainfloor and the toilet enters a 3" stack directly without a vent. The sink connects to this...
