You’re welcome and thank you for the kind words! 😎

Thank you sir, I was able to fix my toilet flush issue.

[@HacksbyDad]

Glad to hear it! 👍😎

[@jomo8385]

Thank you. You really explained this well. Is there a way for me to send a picture of my Kohler cistern tank? It has an extra tube from the double flush.

[@HacksbyDad]

Ummm… what’s a cistern tank? 😎

Best vid out there

Thanks! Much appreciated! 😎

So, from what I'm understanding, you can only fill the bowl so high before water will be siphoned out of it? Is that correct? If so, how do I determine the proper level...not too high, but not too low? Thanks for your good explanations. I subscribed based upon this video alone.

Thanks for subscribing!
Yes, there is a maximum water level for the bowl. Anything more will spill into the siphon and down the drain. SLOWLY pour 1/2 gallon of water into the bowl and the resulting level should be max level. Mark the water line with a pencil mark for reference. Flush the toilet and see if water still flows from the refill tube into the overflow tube after the max bowl level is reached.

My toilet tank does refill automatically when the float is at the bottom. Any ideas about what needs to be adjusted?

[@chrisklest1238]

Why does your refill tube aim into the overflow tube? Mine was like that and was wasting tons of water because most of the incoming water was dumping into the bowl, that was already full, when it should have been filling the tank.

I have an issue now where the tank is slow to fill. I replaced the toilet flapper but when shutting off the toilet supply line the valve is completely tight and closed and water is still supplying the tank. So I figure the bibb washer on the shut-off valve is already worn. So I still managed to replace the flapper and have someone hold the fill valve float to closed position while adjusting the flapper chain and float to optimal setting. After 2 days, the tank is slow to fill. I was thinking small debris from the shut-off valve bibb washer has lodged inside the fill valve ports! I need to replace the shut-off valve or replace with brasscraft rebuild kit but now I have to shut-off the main water lines in the house.

[@HacksbyDad]

Sorry to hear that. Replacing the shut-off valve can be a pain.

[@ybrik5937]

@@HacksbyDad I may call a plumber to do this. It's a pain for me as I have no room to make a mistake if I do it myself as the whole house has no water supply during the repair. I'll ask the plumber just to replace the internals with rebuild kit which I already purchased.

Is there a few different designs or are they all now the same as this ?

[@HacksbyDad]

There are different variations of all the components. 😎
