Question about Kohler Toilet - One Piece with Ingenium Flushing System - San Raphael by

Open Question

I have a Kohler 1 piece model 703 toilet and I need to repair the flapper. However, when I looked inside the tank, the large rubber gasket has deteriorated under the flapper and I don't know how to take the mechanism out to replace the gasket. The mechanism that sits on the gasket appears as if it locks in with three tabs below but I have no idea ho\w to remove them. I'm pretty handy but this one is stumping me. I also need to know where I can buy replacement parts. I need some expert advice. Thank you

SOURCE: not the float

Had a similar problem with a Wellworth after changing out all the replaceable parts. The new triangle gasket + nut kit was missing the flat anti-friction ring needed to allow the plastic nut to be hand tightened enough against the rubber gasket - without the ring the friction stops the nut turning, and you get a leak because there isn't enough pressure on the gasket. Retrieved the old ring from the trash & put it in - works perfect now! not sure if this is your problem too, but you might want to check the locknut / gasket tightness & seal.

That is a tricky one. Tighten the tabs, twist into place, then tighten a bit more. They are a pain in the a$$, but with patience you will get it done. Good luck

The top of the pipe above the flush valve is threaded if you unscrew this you will be able to remove the flush valve and replace the gasket. I am assuming we are talking about the same here is a link that has all the parts:

Try adjusting the float level. The float is what tells the toilet to stop filling. If the float is set too high, then water will just go down the overflow tube and never be able to get to the level it needs to turn off.

Hi,
The model 703 was replaced by part number 1068030. go to the kohler.com site and get to the part area and search for 1068030.

You may just need a new flapper - 1010376 part number

I need to replace the flapper on my kohler model 703 toilet but don't know that part # can you give that to me please.


Kohler toilets normally have the part numbers on the underside of the the tank lid. I was not able to find the 703 model listed on the Kohler sites; check under the tank lid there for a more complete model number and possibly a specific number for your toilet flapper.

Here is a fairly user friendly site with an illustrated selection of Kohler replacement parts. You may be able to match your model number or measure and visually match a suitable replacement:

Your other option is to turn off the water supply to your toilet; remove the flapper and pay a visit to your local plumbing supply store. In some cases you will be able to use a universal repalcement part as long as the means of attachment and the size are the same.

Hello, W/D here.

With the water off, drain the tank (lift the flapper). Look inside where the flapper seats. If the (usually black) gasket is rippled, this may be the cause of your trouble. You can remove the rippled portion of the gasket with a razor knife, just be very careful not to damage the flapper seat. Removing the protruding material will allow the flapper to fully seat without damaging the gasket integrity.
Best regards,

contact Kohlet online or there 1 800 number. They have all the parts but they also charge a lot.

Me I would turn on cut-off valve then go to Home Depot or Lowes and explain problem and tell model 703 and they can look it up and order your parts. They may even be cheaper then from Kohler.

I have the Kohler model 703 one piece toilet. It runs once about every ten minutes. It sounds just like a flush but nothing happens in the bowl. Any ideas?


Something is leaking. Your description sounds like tank water is slowly leaking and then the tank refills. You really need to use Kohler brand parts, as others pieces seem to not work well.

Jacuzzi sent me new rubber gasket for attaching flapper assembly to tank-(held in place with a large white plastic nut) Does the totally flat side of the rubber washer face the tank or away from the tank?...


The rubber washer goes to the inside of the tank under the flush valve which gets screwed on with the large plastic nut on the bottom side of the tank. Then the foam gasket fits over the plastic nut which goes into the toilet bowl hole for the water to flow into the bowl. Tank needs to be removed from the toilet bowl.

HOW DO I CHANGE FLUSH SEAL ON KOHLER ONE PEICE TOILET


The flush seal is the rubber gasket between the tank and the bowl. You do not have one. So I am guessing you mean the wax ring on the floor?? They usually only get replaced when the toilet is changed, unless you spring a leak. Or are you talking about the flapper inside the tank that holds the water till the flush lever is pulled? Get a new flapper, if it is just the flapper you need, otherwise you will have to buy the whole thing, all these parts are available at the hardware store. I think it is held on by a couple screws in there, might just be a press fit, we don't see too many one piece toilets. And the wax ring is about $2, but the toilet has to be unbolted from the floor and water disconnected, clean off the old wax, put on the new ring, smoosh it back down and bolt it back it up. Don't for get the water line. Check to make sure you have no leaks. Hope this helps.

Kohler two peice toilet the water just circles and will not flush.there is plenty of water in holding tank that run through


These models need to have a flush valve flapper that has a styrofoam float on the lift chaninof the flapper. Go to hardware store or home improvement store and get a 'Korky brand toilet tank flapper with float 'ball". Cut the rubber ring piece away from the flapper and you don't need it (see cut here marks on flapper). Install flapper and adjust the float fairly close to the flapper.
When the water level drops in the tank and reaches the level of the float on the opne flapper, the flapper quickly closes causing the toilet to have a "surge" of siphon action which forces the water in the bowl to be drawn out.
