I did a sketch of a bathroom plumbing, would like to know if 1 vent is enough or if you have any suggestions.

Hi Ladijurack...

Definitely some issues with your layout, OK?

To be able to help here, please find out if WET VENTING is allowed in your area (call a local plumbing inspector if needed). If wet venting is allowed then I can probably draw something up that can help here, but tell me, is that TWO toilets in the bathroom? If not, what is the other drawing of the toilet trying to show?

If wet venting isn't allowed in your area then you will need individual vents for all fixtures.

Let me know more, OK?

Mark

PS: You cannot use TEE fittings for drainage fittings on the horizontal piping so we have some work to do on this one... ;)

Thank you for your quick answer, Mark. I just checked and wet venting are not being used in Florida. There will be only one toilet in the bathroom. The second toilet is in the second bathroom connected to drain where I would connect it to that toilet, if possible. However direct connection to drain line would be possible but much more cutting concrete wall. What suggestions would you have for my layout? Also what do you recommend for water supply line cpvc or brass, if barried in the floor? Thank you very much for your help.
Best,
Ladi

Hi Ladi...

I'm afraid you lost me abit here... ;)

Are you saying you want to connect this bathroom into the toilet drain in the other bathroom? If so, that will depend on how the drains are hooked together in that bathroom. In other words, you can't connect this bathroom into the toilet drain if it inteferes with the venting of that bathroom's fixtures, right? However, if you can connect behind the other fixture connections and don't intefere with that bathroom's vents you may be able to save some chopping for sure!

Anyway, for now, I am glad to work up a diagram or two for you but will need you to give me a little time as I will need to draw things up AND I want to double check on the wet venting as I thought Florida allowed for wet venting..?

Let me know what you want me to do, OK?

Mark

PS: CPVC water lines are probably the most reliable and easiest for a homeowner to install, but if you can rent the proper tools, I would recommend running most of this in PEX tubing/fittings (google it).

Thank you so much, I would greatly appreciate it. The other toilet is connected directly to drain line, which has got a vent line heading up to the roof.
Thank you, again.

OK... check back in a couple hours. If I have nothing up yet then I am waiting to confirm the info. On wet venting in Florida and will post tomorrow sometime at the latest, OK?

Mark

According to my code books, wet venting is ABSOLUTELY ALLOWED in Florida?

Double check with your inspector, but I've drawn this up using the one wet vent, OK.. see image.

Notes on the drawing are as shown. Pipes pitch at 1/4" per foot of piping. Hang all pipes every 3-4 feet. The vent pipe needs to pitch toward the drain so any rain water or condenation that gets in the pipe falls back to the drain VIA gravity.

Also note that the 3"x2" wye for WET VENT rolls above the center of the drain line to be a "wet vent", OK?

All fittings are WYE fittings unless noted otherwise. You can use a sanitary tee fitting in the wall to pick up the sink drain. Also, not noted in the drawing is that the elbow fitting that goes to the tub must also be a LONG SWEEP 90, OK?

Otherwise, all is as noted.

Again, double check that wet venting is allowed. In my Florida code book, section 909 (909.1-909.3) wet venting is exactly how to do this job... ;)

To determine how all this connects to the other bathroom I will need more info. Update when you can.

Hopefully this has saved you some time and money (material/labor). Let me know what you think, OK?

Thank you gentlemen, this is the most useful site I have found. Mark, if you have time can you, please send your suggestion. I have to break the concrete floor to run that plumbing. Trying to do it the smartest way.
Thanks for your brains.
Regards,
L.

Glad to help but I actually can't tell you much until you start chopping the floor up and see what is existing under the ground... ;)

Post back once you get going, OK?

I will. Thank you Mark!
