will this replace the original thu369s flapper ?

It should. I used it to replace on my Toto brand toilet. However, it only lasts about a year.

It should. This one replaces mos TV of the flappers. It replaced on my Toto brand. Only problem, it lasts about a year.

Not sure. I did not have the model you mentioned. But, the description within this replacement best describes what it does replace.

Do not use this part as a replacement for an older style flapper valve. It is designed for specific models and will not work.

Yes, this flapper will fit the ST 743S. My understanding is that it fits all Drake model toilets. I do not know what you mean by a "water saving hole." I am not a plumber. I can only tell you that the one pictured to the right is the correct one. It does have a small hole on the bottom, as pictured.

If even if it does fit I would change the toilet out. We had the original 3 for 8 years. They leaked. We replaced and those 3whic only lasted 2 years. The design has a very high rate of failure for the 503 series. Last week we changed those out for an Advantage Gerber model and avoid another flood. Their customer service is virtually non-existentant. Lots of lawsuits againts the 503 series!

I would like to add that it will flush easily if you have the "sweet spot" on the chain for the flapper. I had to replace my flapper (and the lever because the plastic inside broke) and didn't get the right spot on the chain the first time so we had to hold the lever down for much longer. So, if you ever have to replace the flapper, make sure you note where on the chain the previous one was attached so you can match it.

It should. You need to take the original one along with the new one to a locksmith so they can sync it the same as your other one.

Hi, I would stick with the OEM valve THU138S found here https://www.guillens.com/Toto/2P_Toilet/Nexus_CST794SF.htm

Check parts list or toilets that this flapper will work on. I know it works on several toilets but all if the ones that I have installed are a different model than your. Double check with Togo web site

I bought by "sight" hoping it was the right one for my daughter's bathroom faucet not knowing her model number. It was!! I looked up the model F 8h6 and it looks like my daughter's. So I would say yes to your question.

Lilianna:I am not sure if it will fit that model number. I do believe that all the fittings are standard so I would tend to say yes. Not sure though!

sorry, can't say, since I ended up returning it... my plumber, bless his little heart fixed the old one.

It did not fit mine - it is the older "original" model. It was slight too large in diameter.

Don't believe so, I had a plumber install it and it was a replacement for an old one the same size.

I'm assuming by number you mean model numbers. If you have a pump that looks the same as that one it will work promise as long as you hook it up same as the old one

What is a THU138s flapper? If in doubt, take the flapper to your local hardware store for replacement.

Yes. But the sweep at the bottom is not as deep as the original and water gets under the door. Hope this helps.
