20 Most Recent Toto UltraMax One Piece Toilet, 1.6 GPF - CST854S-11 - Colonial White Questions & Answers

Your Toto has the "G-Max" flush valve system. The Korky/Lavelle folks have a carded replacement flapper #2021BP for it. It is red in color and the only generic flapper that will work on your toilet. While it may look the same, do not confuse it with the blue flapper #2022BP. Known as the PowerMax flapper, the blue color is to distinguish between the two and the flappers are totally toilet specific. Let your fingers do the walking and locate a hardware store near you that carries the Korky/Lavelle brand or it can be ordered online from several places using the part number for your search word.
If the fill valve ever stops filling correctly, the Lavelle "Quiet Fill", #528BP, is what Toto uses in most of their toilets.

replace the syphon.

If you are able to identify the source of the leak, you may be able to fix it yourself. If the leak is coming from the brass connection, you may need to replace the connection or tighten it. If the leak is coming from the plastic, you may need to replace the plastic part or use a sealant to stop the leak. If you are unable to identify the source of the leak, it is best to contact a professional plumber to help you diagnose and repair the issue.

It sounds like you may have a problem with the water pressure for the rear wash setting on your Toto Washlet. Here are a few things you can try to troubleshoot the issue:

1. Make sure that the water supply hoses for your washlet are securely attached and not kinked or clogged.
2. Check the water pressure at the source (e.g., the wall outlet or the valve under the sink). If the water pressure is low, that could be the cause of the weak stream.
3. If the water pressure is fine, try cleaning the nozzle for the rear wash setting. Sometimes debris can accumulate in the nozzle and cause the stream to be weak.
4. If none of these troubleshooting steps help, you may need to contact Toto customer service for further assistance. They should be able to provide you with additional guidance or arrange for a service technician to come and check your washlet.

Start cleaning flapper. If it does not work then replace toilet flapper.

Remove the batteries straight away. That is always imperitive to avoid damage to the electronic components. I had similar issues yesterday with a television remote and a cat spilling water on it. I shook it dry very vigourously. Then I got a hairdryer with a concentrator nozzle on it set to hot and high blower for a couple of minutes each side. Be careful, is is gery hot, and if it is too hot for your fingers, move it away.Then I turned it to low and left it on the counter with it blowing into the battery compartment for 10 minutes and then the button side for 10 minutes. It worked okay after that apart from the zero button and the record button. today those two are fine. https://www.google.com/search?q=Coco+Bidet+CCR-9510RS+remote+replacement ..

It needs a new flapper valve. It has to be a proper Toto one and they are 4 times the price of a standard flapper. They are guaranteed though, IIRC 6 years. Easy job to replace. I had 5 Toto toilets in an airport business class lounge and replaced a couple of them. https://www.google.com/search?q=toto+toilet+flapper+replacement ..
