Toilet Repair
 

Slow leak. Used to the old flapper valves- This one has something not seen before- Seems to be all one piece .2013 CYV- any idea if Lowes carries these and if so how hard is it to replace- thanks

If it has a large cylinder that moves up and down, it provides to same function as a flapper. There is a red or yellow gasket at the bottom of the cylinder that is about 4 inches in diameter. Turn off the water, flush, then lift up the cylinder and peel off the gasket. Replace it with a Kohler yellow (not red) gasket that you can buy at Lowes, Home Depot, and ACE Hardware.

and dont forget to look at you tube for repair

I will add to make sure the seat in the porcelain tank is clean of any debris. There are youtube videos on this if you are not sure how to proceed.

I just made that fix with a Kohler replacement part. Easy enough to do.
Be aware, it's not a one piece unit anymore and it's mostly cheap plastic.
There are 3 pieces. The one I had to replace was not the stopper part, but the part that had the "bulb" water shutoff, that wasn't working, and so the water kept filling.

Youtube videos were helpful.

Why only yellow- what is the difference?

Apparently, the red ones break down and do not last as long. At least that is what I have been told.

It may be the case that you get what you pay for.

I replaced one (don't remember the color) with a yellow one from a single-pack. it is still working.

I then bought a two-pack of yellow because it was cheaper than the single. I am now using the second of the two-pack because the first one has already failed.

I bought a spare. This time I got a two-pack of red because it was significantly cheaper than the single yellow. I'm now thinking that may have been a mistake.

Agree.

I too am old school. Simple standard parts. Well that is long gone. They gotcha by the parts. There should be a brand name on your toilet. Kohler is commonly used and what others have suggested. You can take a picture of what you have and people at Lowes or perhaps a neighbor can help you. It, it is the Kohler it is all PLASTIC PARTS. Changing the large O RING like 4-5 inches a cross the first time takes a bit of force.

UTUBE there are videos for most everything. Kohler there are several. The ballcock. The way mine was done, you need to use the old hose. To change it you need to change the shut off valve.

Once you go Yellow , you become a smarter fellow

Or you could "call the guy"

Once you watch the youtube and know how to access it, after you remove the old gasket from the bottom of the plastic tube, just flip it over to the other side in a pinch, I did that two years ago and it's still going strong.

This could be what you need:

Very easy to replace.
