Gerberit Concealed Tank Toilet, Fill Valve Question…

Ted W. | Posted in General Discussion on April 7, 2014 03:05am

Hi All,

My client has a Gerberit toilet, the type with the tank hidden in the wall, and it does not flush properly. It make plenty of splash and noise that would impress Al Bundy, but solid waste almost always requires a couple of flushes. I adjusted the tank water lever as high as it will go, which helped a little. But two thing I noticed are the water in the bowl seems to be lower than it should, and the little hose that runs from the fill valve to the overflow is missing. Also, water does not come out the little nub where the hose would connect.

Is there a reason why this little nub doesn’t spray water into a tube and down the overflow, like every other toilet I’ve ever seen? And is there a way to get it working like it seems it should? 

Thanks

    What does the spec sheet / parts blowup show?  If it's not lost in the bottom of the tank-and no one stole it-maybe in this "state of the art" crapper don't have one...........

    I assume you have contacted the manufacturer and sought their input? 

    My only experience is seeing it on display and looking at the framing for it.  I took a look now and the 3 I pulled up were dual flush toilets.  Is your clients?

    The online parts list I looked at didn't show a hose.

    http://www.geberit.us/RepairDrawings/RP109-304-00-5.pdf

    They do state that it's "dual flush".  Are you sure you're getting a full flush and not a half flush?

    1. calvin | Apr 07, 2014 07:27pm | #3

      Dan

      the only floor mount dual flush I've .........................used, had a 2 stage button-partial half moon button was single flush-bigger portion of button-dual flush.  Think it was a toto.

      Is that the way those dual flush controls work?  

      We just got indoor plum'n.

      1. DanH | Apr 07, 2014 07:34pm | #4

        I'm kinda with you -- to me "dual flush" means you empty the bucket twice.

        I've only occasionaly read about the units.  On some you lift the handle for a half-flush and push down for full.  Others you push and hold for full.  One would need to read the actual operating instructions for this unit, I suppose, but, hey! real men don't read instructions.

        Hey Calvin, congrats on the indoor plum'n... the ol' outhouse will be useful for smokin' fish and beef jerky. 

        1. DanH | Apr 08, 2014 06:59pm | #9

          I'd let it air out a bit first.

        2. calvin | Apr 08, 2014 07:13pm | #10

          Ted

          thanks for the congrats........

          You know, it was a two seater-damn enough room to put a set of bunk beds in it...........

          Which brings a comical winter tale to mind.

          After a blizzard in Jan of '77, we shoveled out to the 2 seater.  Drifts head high-some higher.  Worked a good part of the morning.  The door side was drifted up to the roof-another hour and we could open the door..................one solid white from floor to ceiling.   Shoveled out one of the seats and sure-snow down in the hole.

          The positive side-married my wife the next fall and she had me promise we wouldn't live in that fine palace of mine.  Rent was REAL cheap and if you didn't mind a couple pushes on the pump handle-very good water.  Ah, the old days-times were so much simpler then.  That following January there was another big snow-aptly called the Blizzard of '78.  We couldn't go anywhere for 5-6 days, but we were much more comfortable.  Didn't have any power but we did have the wood stove that kept us warm the winter b/4.

          Still married-still got the stove in the shop.  Made a good decision on both!

          You're up by Chicago, no?

            Haa!! I thought we were kidding about the outhouse.

            In 1973 I spent a few months down south, way in the backwoods of Alabama, where we had an outhouse to do our business. I was warned to watch out for snakes whenever I used it, but the worst that happend is I got stung by a hornet once. Good thing too, becasue the rule is if you get bit on the leg a friend will suck the poison out. You get bit on the buttox, it was good knowing ya!

            Yes, I'm in Chicago, up on the north side. And I do remember the blizzard of 77. I also remember the one in 67. My brothers and I dug tunnels through it.

            I haven't been here at Breaktime in quite a while. Looks like it slowed down a bit. 

          2. calvin | Apr 08, 2014 09:18pm | #12

            Ted

            yup, it slowed down alot.  The jive part, almost non existent.  But hey, small town or a crowded big city?

            Come back when you have the time.

            '67 graduated from HS, too excited to remember much about that winter.

            And I know it's hard to believe, but I think the Glass City beat out Chi-town in the snow dept this yr.  Over 7 ft is way more than normal.   You can have the title back (or Minn for that matter).

            "Small town or big

            "Small town or big city?" 

            Are you asking about where I visited Alabama? No town.... dirt roads... middle of nowhere. It was called Summiton which I assume was the name of the county. It was like a scene from Deliverance.

            I don't come around much anymore because I don't do much that requres any advice, and don't really know enough to offer any that isn't quickly trumped by better advice. The comradery around here was nice, but looks like that's pretty much faded.

            How's quitintime going? Oh heck, why am I asking? I'll just stop by there and say hi. See ya there!

    See the "service" section

    See the "service" section here: http://www.geberit.us/pdf/installation/997.006.00.0.pdf

    There is an adjustment for water level.

    And the dual-flush units appear to have two buttons, the single-flush units only one.

  4. gfretwell | Apr 08, 2014 12:11pm | #6

    I have one with the Toto bowl. Short answer, it is a bit shaky and very sensitive to the actual pipe you are dumping into. It never seems to actually develop enough interia in the water column to suck out the trap. I suspect that is why it doesn't need to refill it.

    We end up holding the flush plate in until it is not flushing anymore. The system still seems to bypass enough water to keep the trap full.

    Thanks for your input everybody, and sorry to take so long getting back... it's "busy" season (yay!)

    It is the dual flush with half-moon big button and smaller instet button, as some of you described. I definitely tried the big, full flush one.

    I guess the nipple is there for other models which do use it, but this model doesn't. I got the tank to fill to it's max during my last visit, before starting this thread.

    I think it's best I just tell the customer that's all I can do.... no charge.... lesson learned. There's probably a knock-out inside that fill valve and I probably could retrofit a piece of tubing to the overflow, but I'd rather not take a chance on possibly causing damage or opening a can of worms and end up regretting it, especially since it busy season (yay! again). I've got a long list of other, more doable, things to do.

    Thanks again for all your input.
