majorsax Posted October 16, 2008 Report Share Posted October 16, 2008 Hello all, I hope someone can help me out . . . I am trying to plan out a new bathroom in the basement and have noticed that, in order for the toilet to be the correct distance from the wall, it would sit directly over the main drain running beneath the surface. I have tried different layouts with numerous fittings and I always end up with a scenario where the toilet is either too close or too far from the finished wall. Is it acceptable to connect the closet flange directly into the 3" side of a 4x4x3 waste T, which would be in line with the main drain? Please see attached jpg for a clearer picture of what I mean. Thanks all! Major Image Insert: 44.1 KB Quote Link to comment Share on other sites More sharing options...

Thanks all! Major As far as the vent goes, the IRC doesn't require a vent on a toilet waste line, while the UPC says that you have to have a vent within 6' of the closet flange. I have no idea what your Canadian plumbing code says. Personally, I think it's a really good idea to have a vent within 6'. It will reduce the likelihood of burping at the toilet when a slug of water comes along from another fixture in the house. To the rest of it, there's nothing wrong with locating your toilet directly over the main waste line. However, your drawing shows a sanitary tee. That won't work very well; you should either use a wye plus a 45-degree ell or use a combination tee. These both direct the waste along the line of travel and lessen the chance that the product will separate from the water. When the product separates, it can lodge in the pipe and cause clogs later. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
ghentjr Posted October 16, 2008 Report Share Posted October 16, 2008 You could also consider a toilet that flushes out of the rear. It would give you a few more inches between the main line and the toilet trap. It requires being up against a wall but other than that works fine. http://www.us.kohler.com/onlinecatalog/ ... 1282740069 Quote Link to comment Share on other sites More sharing options...

There would have to be enough space between slab and the main pipe , though. Combos are much "taller" than a san-tee. Quote Link to comment Share on other sites More sharing options...

Wall-mounted WCs are great and it's much easier to mop the floor under one. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted October 16, 2008 Report Share Posted October 16, 2008 Holy Crap! Did you see the list price of that wall mount? I would live with the configuration you proposed before I spent a grand on a toilet. In fact I have a WC in my house that has the flange attached to a close 90, and that still didn't fit so I trimmed half the colar off the 90. After 10 years it still works fine, and this is in the main bath so it gets used frequently. Tom Quote Link to comment Share on other sites More sharing options...

They're readily available for $300-$400. A close 90 under a toilet isn't a big deal. In fact, a standard closet bend is really just a close 90. A sanitary tee on its back it a bigger problem because it will allow the solids to separate from the liquids. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted October 16, 2008 Report Share Posted October 16, 2008 Jim, you may want to follow the link. It is not a typical wall mount, and I have never seen anything like it. It is a combo wall/ floor mount. It looks like 2 bolts go to the wall and 2 to the floor. It seems like a good design, just not for the money. Problem is that you can't mop under it.......

ghentjr Posted October 16, 2008 Report Share Posted October 16, 2008 I just chose a link to a wall mount, did not look at the price. They are available for mucho lesso dinero. Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted October 17, 2008 Report Share Posted October 17, 2008 It's only 755 in white. Is it me or does the term 'rear discharge' seem superbly appropriate? Quote Link to comment Share on other sites More sharing options...
kurt Posted October 17, 2008 Report Share Posted October 17, 2008 Anyone here ever actually set a wall mount? Even with the wall mount, one is into the floor and main sewer in a big way. If the whole thing is hammered up for a wall mount, put in the right fittings with the appropriate clearances, and install a plain old toilet, no? The work isn't the pipe, the work is digging it all up and making it accessible. Once you've got pipe you can get your hands on, it's Tinkertoys with rules. The miracle of Fernco.........

hausdok Posted October 17, 2008 Report Share Posted October 17, 2008 Hi, Before I'd monkey around with a main line that's working perfectly fine, I'd probably go for one of these and plumb it up into the existing stack.

kurt Posted October 17, 2008 Report Share Posted October 17, 2008 Naaah.....don't be going all skeerdy cat on me....... Messing with a sewer/drain line that's working just fine now doesn't somehow tip over into a sewer that's not working fine. It's a pipe. Hook 'em together. Read the rules. Water runs downhill.

fqp25 Posted October 17, 2008 Report Share Posted October 17, 2008 Originally posted by kurt Anyone here ever actually set a wall mount? I have, quite a few too. From what I get from this application, a Wall mounted toilet will be just more work. Kurt is right, once you break the floor and dig you can do just about anything you would like. As in offset the main line to accommodate the proper configuration for your new toilet, if it absolutely has to be in that exact spot. Who knows, you might even be to get a vent in there. At least it's not Clay or Cast Iron. Frank Quote Link to comment Share on other sites More sharing options...

fqp25 Posted October 18, 2008 Report Share Posted October 18, 2008 Steven, Geberit is a nice toilet.(2nd pic) I like the sledge hammer laying next it.... How will they finally support the cast iron for the sinks? Will they just keep those 3-2x4's there? It seems like the whole thing could just twist, and fall apart.

ghentjr Posted October 18, 2008 Report Share Posted October 18, 2008 Originally posted by kurt Anyone here ever actually set a wall mount? I have one in my lower level for the entire 30 years I have been in my house. Works great, but better still, it would allow for a vent above the waste line connection for a better installation. The advice about just tapping into the main waste without a vent could lead to problems. Quote Link to comment Share on other sites More sharing options...

Frank The Geberit systems I've seen go in are just like that. The rough plumbing goes in, then the framers came in after and boxed it all out. Monster big ticket for those fancy crappers. Then came some sort of fancy color panel, and then over that came custom fit etched tempered glass covering. Single panes of glass 10'x9', all holes for all fixtures already cut out, and laid over the fancy color panel. All 4 walls and ceiling in the bathroom was glass like this. Floor drain. Hose 'er off, squeegee it down. It was pretty cool. Personally, I kinda like those Toto's with the heated, music playing, programmable warm water spray down where the sun don't shine jobs.............everyone should have one.

StevenT Posted October 19, 2008 Report Share Posted October 19, 2008 Yes, everything got framed out after the plumbing was done. The trickiest part was shifting the vent stack. This was on the 10th floor of a 20 story building. It was converted from commercial to residential in the 70's. Alot of payola, there were open fire penetrations from the basement to the roof. The plumber was afraid to cut the stack, I had to support it for him... no problem. It's hard to tell in the picture, but to save space, the walls were framed with 1-5/8" metal studs, I supported the frame with kindorf. It is a nice toilet, I dont like the flushing system, the push buttons are kinda chinsy.

No Creature Is Sillier Than a Human With Too Much Money [:-boggled LOL, all my guys said the same thing. Hey man, I didn't design it, I just built it. The sinks came with a "salad bowl" that had a large o ring on the bottom so it wouldn't slide, it sat on the sink if you wanted a bowl of water.
