At each flush of the toilet the water in the bowl moves slowly and weakly. The first time the bowl water rises a bit and gradually goes down. This is followed by a slightly stronger second dumping and then finally shut off. The toilet is a kohler brand and is of the water -conservation type. I have snaked the unit. opened all the rim holes, put is lime dissolving chemicals. Need advice..

Re: toilet flushes weakly and two times
After working for ROTO-ROOTER for 20 + years, I have come across this problem more than twice. There are many problems that can be included, but let's start with the most simple and go from there. Step 1... Check your roof vent to see if it is obstructed with debris, such as birds nest, frozen ice, dead animal...etc..... To check this you must go onto the roof and find the sewer vent(it is not hard to find as it smells like sewer). Visually look into the vent even using a flashlight to make sure there is nothing obstructing the vent pipe. certain things can clog your vent such as Debris,Birbs Nest, Ice, dead animal,Etc..A drain line needs a air vent so water can flow....If nothing is visually seen , have someone flush the stool. If you cannot see any obstructions and HEAR THE FLUSH, Your Vent is okay. Check out plumbing and venting on the internet for more reference. If this is not your problem then you must pull the stool and see if there is an object stuck in the toilet......Comb, toothbrush, Etc... The best way is to pull the stool from the floor and look from the bottom of the toilet to see if there is an object stuck inside the stool.Turn off the water supply and disconnect it from the tank. Go to your local hardware store and buy 2 wax rings with plastic flanges and a set of flange bolts(these are cheap and can be returned if not used).Turn off the water supply to the toilet tank and flush it to drain all the water from the tank and the stool. You can use a shop vac or an old towel to remove the water. After removing the stool, lay it on its side and look from the bottom to see if there are any obstructions. You may need a mirror and flashlight to see inside the gooseneck of the stool. If you cannot see any obstructions, you can try to dump a 5 gallon bucket of water through the bottom of the stool to push the object out the way it entered. NOTE: When reinstalli8ng the stool, be careful not to over-tighten the floor flange bolts as you might crack the toilet......Joe

If it has a power flush (i.e hole about 1" in size opposite side of flushing direction) that hole gets plugged by minerals from the hard water, when it does the flush will be much weaker. To clean it, use a bent coat hanger and ream out the deposits as far in as you can reach. Then turn off the water supply, flush the toilet, then quickly pour one pail full of water into the toilet to drop the water level to minimum. Get "Lime Away" at H/Depot, pour in 1 cup and let sit overnight to eat the remaining hard water deposits from the bowl and power flush. In morning turn on water flush a few times, should wok good as new. Repeat anytime hole starts to get plugged.
My toilet had the same problem a few times. I managed to clean it out because the pipe is somehow connected to the downstairs drainage pipe in my house. What fixed the toilet clog was going to the source of the problem and pouring extremely powerful hair clog remover chemicals in it (I did have to open all the windows and get the pets as far away as possible and wear a mask). After the specified amount of time waiting, I went to go flush and it worked.
I would recommend doing the same thing but only if everyone in the house is gone for 1 hour. Also I would air it out by leaving windows open, not first floor doors or windows though. It can be deadly if inhaled for extended periods of time. The more powerful the cleaner, the better the results but the deadlier it can be if inhaled. Try this.
My second guess is that it may be the plug inside the toilet's tank. You should check to see if it is working properly. Try flushing with the lid off and watch the plug to see if it is working properly.
Try getting a bucket full of water and dumping it pretty rapidly into the toilet bowl. This is essentially what happens when the toilet is flushed normally, but it removes the variable of how the water is being delivered from the tank to the bowl. It should swirl and go charging down the drain, quickly leaving the bowl with very little water. If it does not act that way, then problem is definitely that the drain is obstructed. When you snaked it, you probably used a fairly short snake (about 10 feet?). Try a plunger - use a good one not the kind designed for sinks. Flush multiple times and get vigorous with it. If that doesn't clear it you will have to remove the toilet and use a much larger and longer snake (50 ft or more).
Sounds like you have a clogged drainline or vent-stack. Fill a large bucket with about three gallons of water and dump it quickly into the bowl. If the drainline/vent is clear, the toilet will "flush" like a gravity toilet and the water will drain from the bowl almost as fast as you can pour it in.
If the water level in the bowl slowly rises (as if it's about to overflow) and then slowly drains, you have a clog somewhere.
All toilets, regardless of their flushing mechanism, require a clear, unoibstructed drain/waste/vent system to extract waste.
If the toilet "flushes" with the bucket of water, you may want to call Flushmate tech support (the number is on top of the tank) or check out the installation and troubleshooting videos at howto.flushmate.com.
If there is a shower in the same bath is it also draining slowly?
If so check that drain systems air vent, (on the roof).
Find the pipe coming out of the roof nearest the bathroom with the problem and when a second person flushes the toilet you should be able to feel
air moving in and out of the pipe with your hand covering the end. If not the vent could be blocked by leaves or animals etc., this vent has to be clear in order for water to drain properly.
Make a small mark with a pencil or marker that can be erased of were your water line is in your bowl. Pour some water from a bucket into the bowl SLOWLY and see if the water line rises or drops back down to your original mark. If it drop back to the original mark, then that is the way the toilet was made. You won't be able to do anything about it. If it rises and stays at a higher level, then you have a problem with the fill tube in the tank. You will need to call a Pro!
