My toilet is a duravit 1930 series model with Euro style push flusher rather than handle. Internal flushing mechanism is not traditional float ball. toilet water constantly leaks from tank into bowl causing the toilet to intermittenly run to refill. Is this an easy fis x or do I need a plumber?

The level is determined by a floating device connected to the water valve. Some are on an angled arm and some move up and down.
Determine how your valve is shut off and either change the big round float or adjust the clips on the rising one.
Just keep the level below the overflow and the flush handle to avoid a running toilet or a leak.

Hi, Go to amazon and look for replacement parts.... here:

if you can see the water running in the bowl it's a good chance that the flappers warn http://www.aplumbers.com/residential/toilet
1. tank the tank lid off.2. flush the rubber thing that comes up and allows the water to go to the bowl is the flapper 3. remove 4. replace that should fix it.
problem 2
1. tank tank lid off.2. if the waters flowing over the long tube in the center and down then the water level is too high3. adjust the level either it will have a ball **** or a float in either case   a ball **** adjusts by a screw on the fill valve. the float has a either a metal rod w/ a pinch clamp or a plastic long screw type thing.4. adjust water level .5. barely lift handle to allow a little water out til fill valve kicks on then release handle til valve stops .6. just keep re adjusting til you get the water level right there should be a molded in line for the level on the back of the tank.

I had this issue as well with my toilet. My chain was unattached and had been sucked down the drain under the stopper valve preventing the toilet stopper valve from completely closing and causing the water to continually run. After re-attaching the chain I noticed when I flushed the toilet that the handle did not rise again until I manually pushed it up. After readjusting the chain to a tighter position where the chain was not floating at all but instead holding the stopper valve in place I again flushed to check the reaction. This fixed the issue of the water continually running and also the handle not resetting itself properly.

Here is the steps I took to resolve my issue:

Step 1: Remove the lid off of the tank.

Step 2: Check to see if the chain coming from the Toilet Handle to the Stopper Valve is loose, unattached, or broken.

Step 3: Flush the toilet and check to see if the problem has been fixed. If not readjust the chain to a different position and flush again.

Step 4: If all is resolved replace the tank lid.

Other possible things to check:
Check the Float Ball to see if it's Half-way or more submerged in the water. If it is it needs to be replaced.

I hope this helps!

Several ideas. Start to fill? Have you looked inside the tank to see what's going on? If it just filling very slowly, then you most likely have some calcuim build up inside your flush valve blocking some flow, if this is the case you will have to clean the flush valve. If your flush valve is staying up and the toilet is "running" unitil the float drops. The float (either the arm ballcock style, or newer fluidmaster) is rubbing on either the flush lever or side of the tank, and taking longer to drop to let the water start flowing. I

The push button siphon assembly is worn out. Just replace it entirely.

Note: Before doing any major work on your toilet, be sure to turn off the water supply to the toilet...

If your toilet's "guts" have an float ball, try unscrewing the ball a little to lengthen the float (which controls the water shut off)

If that does not work, try putting a little bend in the arm that the float connects to get the ball lower into the tank.

If you are referring to the style float that surrounds the fill tube like a doughnut, most likely you have some sort of build up either on the fill tube the float surrounds, or on the float itself - or both - that is causing friction that not allowing the float to travel (and shut off the water fill into the tank

If you are referring to the flapper at the bottom of the tank that allows water to travel from the tank to the bowl, most likely it is has two "arms" that anchor to the flapper to the fill tube. There may be some buildup on these arms that needs to be removed to allow the flapper to open and close easily.
If the flapper is not closing, you may also have a chain that is binding up when the flush handle is pushed. Clean the chain with some CLR, and/or remove any excess links that are piling up when the flapper is closed.

Which style of flush valve do you have? If it is the dual-flush option (solids/liquids) I do not know how to adjust those. If you have a traditional style, then the flapper or ball is closing too soon. You need to adjust the guide arm (flush ball) higher or shorten the chain between the flapper and the handle. Adjust this carefully or you will have it fail to seat and the toilet will constantly run.

I hope this helps.

(who needed to replace the fill valve and the flapper at her home earlier this week)

bend float down to adjust water level if water is covering float and still not stopping some flushers have an adjustment screw on top also turn slowly a 1/4 turn at a time if still doesnt stop lift float until stop bend rod to adjust if water doesnt stop from lift than diaphragm in flusher bad and have to change out again

One of two things is the problem. First, make sure that you have a tight chain with little slack. If there's too much slack, the flapper won't catch in the passing air to stay up. Second, the flapper is not correct for that style of toilet. You might want to look into purchasing a new Kolby filter that has a removeable cone in the center. Move that cone to 12 o'clock to allow the maximum amount of water to run through the flush valve. If the flapper you have now is flat, it needs to have a cone in the center on the underside.
