Plumbing a basement bathroom

stradt03

Hi all,

I am finishing the basement and would like to put in a half bath. I have superior walls (as seen in the picture below). The markings on the floor are the rough locations of the vanity and toilet....I think I may move the vanity up against the wall rather than leaving a gap between the two.

I have PEX plumbing all throughout the house and the manablock in ~4-5 ft away on the other side of the bathroom wall.

Basically I am clueless when it comes to plumbing code and proper routing of lines. Can someone shed some light on what the best way to go about getting the lines for the toilet and vanity run? Can I just run them through the predrilled holes in the superior studs?

Pics are a few posts down

Thanks in advance!!

Drains go in first---then the water---

Is someone else installing the drains?

Will this go to a sewage pit or main line?

Could you resize the picture?(most people won't look at a post that over fills the screen)

I'd like to consult with a local plumber and try to do most of the work myself...including the drains.

Yes the drains will have to go to a sewage pit unless I do an up flusher. I would rather do a sewage pit though.

I'll try to resize the pics.

Thanks---We will walk you through the drain layout---and the water lines,too.

Pa. is a good state to work in----Mike---

The location of the new pit---and a wide shot of the existing drains will be helpful.

Ok, Lets try these for size.

There is just over 55" between the air handler unit and the wall for the bathroom. It currently has a bunch of Xmas decorations stored there but this is where I was thinking this could be a prime location of the sewage pit.


The sewer line out is roughly 44" off the floor.

Finally got them resized!!!

Great----I think the first one is still blowing up the screen---

As to the plumbing---good spot for the pit---
You will need to locate a two inch vent--
You might not have one---

The master bath plumbing and vent is almost directly above the proposed pit location. Can I tie into this?

oh'mike

Yes--maybe--

I'm going to wait for a licensed plumber to help you with the vent---there are a few restrictions on hooking into an existing vent--I don't want to steer you wrong---

I can't say what the PA inspectors wan,t but being a remodel, I would tie into an existing 2" or larger vent at least 42" above the floor(upstairs). Sometimes it's easy to take the vent up through a closet corner and make a tie in in the attic rather then patching walls.

If this was new work, I'd have to vent the pump separate through the roof- no other connections. PA may want this on remodels too. So it may be wise to pay a local plumber for his consultation time. Oh, and how do you propose to vent the new fixtures? Are auto vents legal there?

I'll have to look into the local code. Thanks for the info.
