The bolt that holds it on is a reverse threaded bolt. Retighten it going the opposite direction. This should do it.

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

Toilet flush levers are always adjustable. For the most part, there are two types of chains that attach to the lever. Ball chain or linked chain. Either way, you'll see that there is a rod behind the toilet handle lever. That rod has many holes. Re attach the chain to the proper hole on the rod that makes the chain taut and not loose. Hope this helps!

Can i put a fluidmaster 400A in a Kohler Rialto

Save that valve... !
Use a fluidmaster (diaphram) part #242 as a replacement substitute!!
Easier than most pill bottles... !!!
(turn off the water)
The valve seems to be very thin plastic but mine lasted 20 years before needing a new diaphram. I cold hear the water going (seep. seep, seep))... and changed the flapper valve... Wrong!
I actually bought the new white plastic one to experiment on... but never got that far... Great price ($26) from Amzn (new spare... still in box)

The white VALVE (right) end of the 1068030 twists off easier ... over the top (clockwise: less than 1/8 turn... there is a little white lock bar on the very back that has to be pressed in to allow rotation).
Ignore the (blue) float lever... you wont be turning anything that far.
The expensive & unavailable KOHLER diaphram can be substituted with a $2 FLUIDMASTER #242 diaphram... available everywhere... Home Depot, ACE, General Plumbing Supply...
(Amazon = $4 +/- shipping, (local "dealer" had nothing in stock... of course)). ships for a whole lot more!
Sadly... THAT very SAME FLUIDMASTER #242 will also fit in the "Kohler 703" valve everybody seems to be throwing away (the easiest valve I have ever repaired).
The GRAY "703" valve seems to be very thin plastic but mine lasted 20 years before needing a new diaphram.
That is a hard twist 1/8 turn: counter-clockwise... same #242 diaphram... 5 minute job!
Six minutes if you hold a cup over the valve and rinse it out like you are supposed to do...

Kohler toliets can be a pain to repair. I have found with them that the only thing to do with them is go to a plumbing company, take the model number with you and replace all in the inner parts to it. You will replace the fill valve and flush valve. After I do this on Kohler I don't have anymore problems with them. It should work for you, just make sure they are Kohler parts. Good Luck

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.

Kohler will try to sell you $46 anchor bolt kit 84999 & also there special tool. You should expect that for a $400 toilet.

Try this instead:
1. Use 1/8" drill bit and drill and drill around the bolt until the anchor material can be removed.
2. Carefully clean hole with 11/32 drill to remove all remaining acchor material.
3. Go local hardware store & buy a 10 - 32 3/8"X3/4" rubber expansion plug (make certain threaded part is brass & has shoulder on 1 end), a 10 - 32X1.5" Phillips bolt and couple of small fender washers fit the seat.(about $4 for 2)
4. Assemble carefully not to over tighten and crack the porcelain.

Hope it helps
