Plumbing review for first time poster and new plumber.

Hello everyone, as the title states, this is my first post. I am asking for you guys to check my work as it is dry fit PVC. I would like to primer/cement it ASAP, but I would like some professional feedback before i cement it all together.

I have added a second bathroom to my house. I followed a few books from the library, and tried to follow all the code laws, please take a look.

The first pic shows the staged bathroom.

Second pic shows the vent line, and drain lines for the sink, toilet and shower. (my house has a vent line running out the side of the house already. i decided to add a second one through the roof for this bathroom.)

the third pic shows the toilet drain on a 90*, All of the drain pipe is 4". The vent line is 2". the vent line connect with a "T" fitting, then goes to a 4" to 2" reducer. the 2" pipe is my second vent line that travels up thru the roof.

Pic 4 is the existing septic tank line that i need to tee into. My pipe runs parrel to it, and i am ensuring i have a downward slope to join the two.

Pic 5 shows two sanitary Y's connecting the sink and shower drain.

Lastly I show the flexible Y recommended to me by my guy at Lowes.




Thoughts? Suggestions? any thing I should change? I passed my inspection...but that was a joke.

 

Anyone....Let me know guys.

 

Not sure where the plumbers are today, but your post is up so someone should be along.

 

I think it looks great.

The problem though with dry-fitting is that some of your pipes may need to be a bit longer once they are cemented. They will sink into the fittings another 3/4" to inch, so may end up being too short when you have fitting next to fitting.

I would have used a 4x4x2 wye for the vent, but no issue with the reducer you have there.

Oh - did see an issue. Your sanitary tee in your 2" vent (about 4' above the floor) is upside down. The air is going upwards, so the sweep should be upward.

You'll also want to add nailing plates where your PVC goes through studs and plates.

As for the rubber wye, I would rather use a PVC 4x4x4 wye with no-hub couplers. Cut out a section of your existing run, add this, and fold the no-hub coupler rubber over. Then tighten the metal shield. I honestly don't know the code worthiness of those rubber couplers, I don't believe they are allowable... but I've never used one before either.

Looking good though!

 

I cant believe it passed. Over venting to say the least..I guess not a bad thing but looks hokey..

Not standard plumbing 101.. Yes that san tee is upside down..

Typically it wouldnt pass in the fact it cant be dry fit and needs to be filled with water to pass..

So If you say it passed glue it all up and be done with it...

Thats rubber Y should be banned..

Greenboard is no longer considered best for showers.

 

thanks for the input. i can certainly flip the 2" T. as for the dry fit, i jammed the pipes together all the way, so hopefully they should be pretty much on point as far as the distance is concerned.

i wasn't sure about the rubber Y either. i originally had a hard PVC one, but i was concerned about using that....i figured i would need a slip coupling, or something. i read about rubber couplers having to be fully banded in order to last. i don't know, i've never done this before, but i am trying to research and seek the best advice regarding it all.

thanks!

 

Sorry, thats the old dry wall. i've got the purple stuff to put up.

 

That gets you about half way into the fittings so be prepared to make some adjustments!

That also depends on what the shower will be!

 

so is the consensus to go with a 4x4x4 no hub wye with 3 of the banded metal clamps? last thing i wanto to do is have a septic leak.

lmk, thx guys.

 

you use no hub couplings.. If its tight fit then you slid the ban on the pipe, then the rubber, and then you roll the rubber back.. Fit the fitting and roll rubber and band back..

 

Dang it! i had the hubless connector/couplings in hand and the guy at Lowes sold me on the rubber 3 way..... This is a big reason on came on this site, i was suspect of that rubber piece, and happy to get some experienced info as this is all new to me.

thanks.

 

Thats proper code as I know it.. To use no hubs..

 

I don't think it looks too bad with the couple of things mentioned. Ten different plumbers will plumb a house ten different ways. Sometimes with a long run of pipe like that it's possible to put a pvc wye in if the pipe will move around just a little bit or lift. You have to be a little careful is all.
