We have to make sure of the terms you are using here. The screws that hold the seat back?
The seat itself has a top that closes but I've not seen a toilet with a seat back... However, if you're referring to the screws that hold the seat to the bowl, you have a big problem if those are what is leaking only when you flush. That would most likely be a crack in the bowl portion. The water goes through that area only during a flush. If you are calling the tank the seat back, yes you would start with the rubber washers. And here is the rest of the story. You are asking for extra work if you only replace the washers. Instead pick up a tank rebuild kit that has the new screws, washers and nuts. That will have the rubber washers included. There will also be the large rubber gasket that seals between the tank and bowl. You can get the gasket separately, some kits include it, or you can get the full kit that will also have the flush assembly as well. If you hear the water leaking when the tank has filled this is most likely the reason. If you take the 2 apart or twist the tank around at all it's easy to get a leak started there as well. And that leak will be whenever there is water in the tank. It's a little extra work but it will save you doing it twice. A couple things to remember if you decide to do this yourself. Get a little container of silicone grease. Comes in a very small pack and you should coat the rubber washers and the threads of the screws with the grease. This will protect the washers and screws over time and help in sealing as well. And don't over tighten everything going back together. You can squash the washers through the tank and have a new reason for a leak. You can always tighten a bit more if you haven't tightened enough at first. ----- Original Message ----- From: Spiro To: [email protected] Sent: Sunday, October 19, 2008 1:31 AM Subject: new question on RE: [BlindHandyMan] toilett I have a leak. When I flush, the toilet leaks straight down the bolt that keeps the tank onto the seat back. Am I right thinking if I can release it, I should put in new rubber washers? Why only when it is flushing? Thanks [Non-text portions of this message have been removed]
