This video is way more helpful and informative than some animated videos that have unnessary gross details but miss the most critical part.

This video is so detailed and so well explained. Thank you🙏

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.

[sorguvasfen]

This was definitely one of the better videos.

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.

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

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

At age 63, I have installed many toilets, trouble-shot many others, but I am having a time lately. The water level is dropping, and I assumed it was leaking past the flapper. Replaced the flapper and it is still leaking. I can't see any rough edges that would keep the flapper from sealing. I thought I must be missing something. The only reason I care is because the shower will nearly scald me if the toilet refills while I'm in there. I still don't know what's going on. Maybe the overflow tube is leaking ?

Something isn't working correctly with my fill valve. Unless there's something else I'm not aware of. I replaced my fill valve with a Korky universal fill valve and no matter how much or little water I let flow into the flow tube the bowl fills up at the same level every time, which in this case is very quickly. According to Korky you're supposed to adjust the water flow for the flow tube so it shuts off about the same time as when the tank is full. However for me the bowl fills up super fast every single time no matter how little water I send through the fill tube. I just don't know how that can be possible.

Back in 1965 they had 4 1/2 gal toilet flush. Everything worked great with the high cost of water in California it was costly to flush. when in that year my Dad worked at in a top-secret Testing Laboratory where my Dad worked that day. He brought home a New and water saving device Fluidmaster 400a'. You could use your old 4 1/2 gal toilet flush and convert to a 1 1/2 gal flush in less than 5 min time. It would flush the same and be easy to install. It saved a lot of money in a year's time. As for today, trying to keep it clean and save time and money is a little harder. You can live with the problem or live with the solution? my Problem was trying to keep my toilet clean and odor free, with a lot of hard water stains Keeping the Water Jets Free from Hard Water? Hard water is a Problem' So I found Spray Bleach from Walmart, every time I use it. Spray a little bleach in the Bowl. I refill the Spray bottle with a funnel. added the 64oz bleach to the spray bottle and a little dish soap to it. Shake it a little and ready to use. Happy Newyear's Hugs wheelchair larry
