    Sewer treatment question

    I am about to change out a toilet. While I have the old toilet removed, can I pour some fruit fly drain treatment down the toilet line? Or should I still pour it down a nearby sink (like I have done in the past)? Also, I have always used a regular wax ring when installing new toilets, but I now...

    Crack in 4" sewer line

    Long time lurker, first time poster. I discovered roots in our sewer main to the street during a camera inspection. The roots are small, and not really causing a problem at this time. Using a locator and wanting to avoid future problems, I dug up the area to find where the roots enter the...

I've been noticing on and off again sewer smell from our HVAC ducts and traced it to the closet where the setup is housed in a finished basement. I've attached a couple photos here that show the...

    Horizontal Wye - angle of branch

    Hi there, I'm laying out a bathroom sewer, I have a few wyes connecting sewer branches as well as vent branches. I know that the slope of the run needs to be 1/4"/ft. My question is, does the branch of the wye need to be turned up (22, 45, 60) and then rolled in the direction of the next fixture...

    How much of sewer line to replace?

    How-do, all. I've been working on replacing my failing clay sewer line (roots, roots, so dang many roots....) and am hoping the collective wisdom here can help me sort a couple things. My sewer line set-up is like this - working from the line outside the house to inside the house crawlspace...

    Rate my sewer lateral [video]

    Hi guys, long time lurker and first time poster. This forum has come up several times when I've researched DIY plumbing tasks so I thought it would be a good place to ask. I recently had a 2 way cleanout installed and then the plumber performed a camera inspection of the sewer lateral. The...

    Tips for backfilling around sewer line repair

    Hi , I had a section of sewer line replaced in the front yard, directly beside the house foundation. The depth is about 10 feet. I'm responsible for backfilling the hole, and I'm trying to determine the type of material to use. I've read recommendations for sand, gravel or soil, and I'm not sure...

    What's going on with my sewer drain?

    Good evening. Twice now, I've snaked my ~98 year old sewer with a full 100 feet of snake, because I have water backing up in my basement after just a 4-5 minute shower. Both times, the 5/8" auto-feeding snake powered ahead with no issues both times. No roots, no apparent blockages, etc. Also...

    Bad smell in new addition

    A few years ago we added onto our house. The addition now sits on part of what was the backyard. The sewer clean out pipe is now covered by the addition, but it was capped off and relocated by a professional plumber. Each fall when the temperatures begin to drop a bad smell comes from that...

    Maximum slope for sewer -- handling a vertical step or drop under CPC/UPC

    I'm trying to find in the UPC the right section to deal with a step or drop in a standard 4" sewer line, where the usual 1/4" per foot can't be maintained. I'm aware that making the entire line sloped steeper can cause problems with solids, but that a drop can solve the problem. What's the...

    How to connect sewer line to City main?

    Tree roots got into my 1965-era iron sewer pipe so I'm replacing everything from the house to the street with 4" Schedule 40 PVC. I've trenched out to the City main and it appears that the connection of the old sewer line was made with concrete. How do I make the new connection? Chisel out...

    Advice on routing new sewer pipe through garage

    I recently purchased a house built in the 1940s with some side sewer issues. Rather than digging in a couple spots at the back of the house to reline the problem segment and continue using the existing side sewer to the street, one bidder (which comes well recommended and reviewed) advised...

    Sewer Replacement: Grade issue

    I'm replacing a 70 year old sewer line at my residence. This line outside the structure is concrete pipe. I will be installing 4" schedule 40 PVC DWV. I've measured the fall and computed the grade for the existing line. It is 1%. This is allowable in my city for a replacement, if there is...

    Sewage Ejector questions. Wet Vent

    I am installing a bathroom in the basement I have to pump up to the drain. For lack of a better name the "Sewer Crock, pump" will need to be vented. Do I have to tie into and existing vent upstairs that runs to the attic-roof or can I tie into the sewer drain and use a wet vent ?

    Fixing improper venting, old house

    Hello, This is an update/new question from my last post. My home has old all copper DWV from 1960 and earlier, with even older cast iron at basement level-down, that I'm replacing with PVC. Plumbing noise isn't an issue; I really don't want to do expensive cast. The current copper has pinholing...

    Copper waste line flat, venting lacking, and so much more

    Hey guys. I need to share a little back story to give proper context of my issue with some upstairs very old plumbing. I live in an old farmhouse that was originally Mennonite-built in 1890. There was no indoor plumbing initially but the main floor bath was put in by my grandparents at some...
