have an old bath(1930's) that i recently removed and am planning on redoing. I have changed the layout a bit so the bathroom is a little bit more comfortable to use since you just about had to put your feet in the tub when on the toilet. My plumber is telling me that the toilet is within six feet of the vent stack and will not need to be vented any closer. The vent stack will be a full 4 inches all the way to the roof. My question is since the house is off ground construction does the pipes running down to dirt level affect the 6 foot rule at all? He says no. I also asked why not just vent the toilet right up the wall and tie back into the larger vent just to make sure we have plenty of venting but he believes its uneccessary. First pic is old second is new layout
tommy,
Forgot to mention that the rest of the house dumps into the main before the bathroom which would make the toilet vent a wet vent if I am not mistaken. I tend to overkill on all my projects and was thinking it would not hurt to give the toilet its own vent to give it a true dry vent. I have the bathroom down to bare studs so it really would not be to much trouble. Thanks...............
A wet vent would be if you vented the toilet through the sink. It will vent fine either way. If you wet vent through the sink, you'll most probably within the 6', but you'll have to vent it with 2".
The first sketch the toilet was right in front of the main stack leading to the roof vent. I guess I am just concerned with other stuff draining(dish washer washer machine etc) and trying to flush the toilet and it having to get air from a line with water. Like I said i tend to overkill on all my projects.
First sketch looks good, you have a vent on both sides of the toilet, you can pull air and push air. On the second sketch you have killed your downstream vent. Really not that big of a deal because it is 4" pipe, but saying you have a laundry and a bathroom group upstream then you will probably (worst case) see the water in your toilet bounce when at full flow.
Pipe drop to the 90 does not affect the 6' rule.
x3 .......I dealt with the exact same issues as you currently are on my last home 2 years ago.....everything worked Perfectly.
As far as your concerns about venting in what you are calling a wet vent, none of your discharges from other sources is of a 4" diameter, therefore your 4" will have tons of room for air.
You are sooooooo right. Was a big fan of Toto and all those "super flush" jobs. Recently moved into a home with some off brand builders cheapo toilets. My daughter has NOT clogged one yet and THAT is THE test. I'll bet they did not cost more that $100 each.
Members of a TOTO forum were always rejoicing that Totos were made in Japan and Georgia (USA) and that was the reason ther are so good(and expensive). These poor folks recently found out that the Totos are now also made in Mexico - ouch!
I don't get this new comfort height craze. The closer you are to the ground, and the closer you are to a squatting position, the better off you are health wise. Countries who sit on thrones have high rates of hemorrhoids, countries who squat do not.
new bath layout, plumbing help needed
