20 Most Recent Toto ULTIMATE ROUND FRONT ONE PIECE TOILET MS853113-12 Questions & Answers

I've installed a lot of Toto toilets and have had few leaks but, not from the one piece toilets. It might be a problem toilet but, I would be sure the drain is not blocked causing a small back up after the flush.I have seen this happen many times. The toilet can be pulled and a 5gallon bucket of water can be poured down the drain to test this before replacing the toilet. also be sure water is not spraying on the top of the tank lid and leaking down the back of the toilet.If you flush the toilet with the lid off it should be easy to see if that the problem. hope this helps.

check your flaper

don't think you r going to get 2 toilet with same problem. I would think you have a broken floor flange instead. rubber seals are great as long as the floor is level and smooth where as the wax seals tend to fill in areas that are not quite level. hope you can get this thing figured out. Toto are great toilets and it would be a shame not want to use it.

If you use a clear caulk around the bottom and the leak stops then we will know it is coming from under and it will need to be pulled and replaced. if leak continues then there would be no need to pull the toilet any more.

I wonder, did they caulk around the bottom where it meets the floor. I guess condensation could happen if the room is very humid. but the condensation would be all over the tank. try caulking the base , let dry and try looking for the leak again. this should isolate if its coming from under the toilet or from the surface.

Have you tried resetting or resetting it to factory settings? If this does not work, I would recommend getting in contact with the company to discuss your problem. There customer service team is here to help you if your product is not working correctly.

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.

They sell every part except the tank! You would have to contact Toto direct, or a plumbing outlet would order it for you. https://www.totousa.com/toto-customer-support https://www.google.com/search?q=replacement+tank+for+TOTO+CST416M-01 ..

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 ..

Remove the screw, then go to any store selling nut. Show your original screws, You can ask them plastic type nut. Buy also small silicon tube. This is use to hold the nut after you put it back the screws.
