wall hung toilets


G Smith: Any feedback on the bowls themselves? The seats?

Now I am sorry that we chose the GroheDal Rapid L. The Geberit instructions are much clearer. We are having trouble understanding the supply connection, as it seems to have no secure it to inside the tank; that is, it is just hose connections with the shutoff in the middle. I have an email into info@grohe, but who knows when I will get a response from germany! We are also working very slowly with the rough in. We have three of these cisterns. 2 are vertically aligned, one on a perpendicular wall 3 feet away.
==> from what I understand after reading the posts, we can make a 90degree turn below the cistern? Or do we need to go through the floor plates first? We (the royal "we") assume that since our vents are all within 3 feet we have no trouble there. How's my thinking so far?

Warner: here is a great link to a bumped out look that G Smith may be refering to

G Smith: can you post any pics?

Thanks to all in advance

wall hung toilets


Kerr,

In the Duravit line the bowl designs seem to vary only a little. Functionally they seem to be the same. Only certain designs are elongated so you may need to check this aspect. Sorry, I don't have any pictures of the last installation that I had spec'd. With in the next few weeks a contractor will be installing a Duravit system in one of my design projects and I will take some installation pictures, but it will be more of a standard installation.

As pictured in the Geberit web page that I previously posted, it seems that once you connect to the outlet on the toilet then you can elbow at any point, with the only limitation being framing. As with all toilets the "P" trap is the toilet bowl and after that the connection can follow any of the plumbing possibilities. Because the outlet from the toilet is above the floor line it is possible to elbow the drain line above the floor framing.

Looked at the URL on your post, and the only comment I have is that there may be a misleading comment or two. The flush actuator can be separate from the actual tank location (costs extra), but never the less, the access panel to get in to the tank for repairs still needs to be accessible. As in this installation, the access seems to be covered by the plywood. I have been told by some plumbers, that you can reverse the top of the tank and have the access panel facing out the other side of the wall. I haven't seen this happen yet. The remote flushing button does allow you to cover the access panel, but, again, this needs to be removable to get to the innards of the tank and the internal tank valves, and parts.

Warner: Any new pics?? Are you flushing yet? I did hear from Grohe. They said that they only support the ceramic fixtures and I should contact Germany. (I though I did! Must have been routed to the US.) I will try Duravit USA tomorrow.

G Smith:
1>> Well, I think that SOLVES the big issue, that is, we need to bend 90 degrees *backwards* to go through the balloon framing down to the house drain in the crawl. I thought I had read somewhere (maybe terrylove?) that it had to go through the floor first; my assumption was it was a suction issue.

2>> I had not thought through the cover plate issue. With the GroheDal, the cover plate "surf" is big enough to cover the entire opening to the tank. The shut-off is then accessible. If I stay with the "surf" then I would be ok, correct? The walnut plywood is my most inexpensive solution, next to paint. I want to varnish it to clean up after the small boy, should he sneak into my bathroom.. The ceiling is only (groan) 7'6" there (barrel) so the vertical might make it more appealing. However, we do have access from the other side of the wall... No, I do not want to invite trouble by turning the tank around. Frankly, I do not see how it could even be done.. Oh, thinking while typing, that is what the remote activator would be for...

3>> Any ideas on how to support the shut off valve? The shutoff valve has 2 threaded connections, 3/8 & 1/2. So far, it looks like this: The tank brass inlet is connected to a 3/8 stainless braided hose, which is connected to the grohedal shut-off valve(3/8 side), which is connected to ?? what? Now, all connections are inside the tank to this point. There are two tank access holes to choose from, behind and top. I pick behind because this allows the shutoff to be worked with a screwdriver held horizontally, or with the fingers. Is the house supply 1/2" pipe suppose to have a threaded connection attached, then attached to the shut-off?

Sorry about the long post. A lot of agita today. (and it took me to the age of 43 to find out that that is an italian slang expression, and not just good old New Jersey english)

Well, looking back on my #3, I have been thick. I checked the Geberit Tessera install instructions, thinking that it would relate to the GroheDal Rapid-L carrier, and they use a drop ear elbow supply.:

Quote:
1. Water supply specification, 1/2 copper - supply pressure
25 - 90 PSI.
2. Extend drop ear elbow supply side with 1/2 x 6 copper
nipple, secure elbow to cross brace (2 x 4 x 193/4) and
install in back of the tank reset section.
3. Remove tank door, install 1/2 NPT shut off valve through
tank opening. Keep valve in shut off position, du not
connect fill valve supply hose until the installation is
completet. [sic] end-Quote

So I guess all of my *current* issues are SOLVED.

wall hung toilets


Kerr I have not decided for sure what I am doing. Still leaning wall mount. But G Smith got me thinking no hub and with that thought in mind I would not need to jackhammer a large hole for my toilet. I need to look and see if I have a couple extra tile to match my existing tile. Then sit back and really think about the pros and cons and actually make a flipping decision. I think my wife is about to shoot me. Can"t blame her 2 weeks ago I was ready to order the wall mount and she has not seen me do it yet. Has anybody out there heard of the Wade brand wall hung brackets. I talked to a guy at Every Faucet and he says they are much easier to install ( made to US standards). They fit the Kohler brand toilets. I was told the Gerberit has a 2 1/2 inch waste line coming out do not know if that could handle my what I hear that I am full of.

Kerr,

A brief reply.

1) The toilet is a gravity drain system and only relies on the siphon action of the P trap to pull out all the water in the bowl, they gravity takes over so you can elbow directly out of the drain adaptor that is provided with the system. This is actually done all the time with floor toilets, with a 90 elbow installed directly after the floor flange in tight floor framing situations with a ceiling below and no soffits below.

2) It seems that the cover/flush plates are specific to the manufacture with GroheDal being more square than the Geberit to fit the tank extension. Other manufacture's flush plates may fit but it would need to be verified. There was one installation in "Finehomebuilding" magazine where the person made a custom tile panel to cover the tank opening, then caulked in the tile panel with color matching caulk to the grout color. This represents extreme confidence that nothing needs adjusting in the tank, because a 10 second adjustment becomes a 2 hour access project.

3) Seems like you solved the supply support problem.

Well, just wanted to thank ya'll for your help. This was a big hurdle for me.
Warner: sorry if I hijacked your post a bit.. And your wife may prefer the wall hung if you have little ones as they are easier to clean! Just saying..

No troubles so far. Pretty straightforward after all. I checked out every google hit and Terrylove.com has many, all encouraging.
