BathTub Overflow Gasket

I purchased a new overflow gasket. The associate at the hardward store said I could put it between the inside of the tub and the overflow cover. I have tried it that way and there is still a leak in the ceiling below. Is that an improper installation or do I have a bad gasket? Any help would be appreciated. Thanks.

Hi,

You have to remove the old gasket. The gasket is really on the outside of the tub. It fits between the overflow plate and the outside of the tub.

Pics would help, but I think its a inproper install or not a retrofit part,

Sometimes its best to replace the whole waste and overflow. But access can be an issue. Waste and overflows are troublesome even for plumbers.

Hi,
Overflow gakets are tapered. Make sure the thick side is pointed down.
Good Luck Woodbutcher

Thanks for the help so far. On the original install I removed the old gasket, cleaned the area and placed the gasket with the thick side pointed down. Again, this is all inside the faceplate. Here is a picture of the tub and overflow drain. I placed the gasket on the inside of the tub, not between the overflow pipe and the tub.

The gasket needs to be OUTSIDE the tub; between the outside of the tub and the overflow piping.

That's what I thought. But the guy at True Value said I should do it the way I described. So, now the problem becomes, how do I get it back there?

Same way you got the old one out. Take a pic of the gasket they gave you. Some are brand specific.

Does it have a groove on the otherside? Does it fit properly around the overflow portion shown in your pic in post #4?

And yes the fatter side should face down. Also those screws nee to be tightened very secure to smoosh the gasket against the back of the tub.

The gasket and overflow need to be centered befor you tighten.

And if it still leaks then on to plan B.

How do you know its the overflow? Is the tub being filled that high?

Is it leakining possible when you drain the tub and its actually the strainer?

Or the gasket could be sealing properly but uts the actuall overflow pipe thats leaking?

This is what you need to determine.

There are no grooves behind the tub. The copper overflow pipe moves a little. But I don't think enough to get the gasket between it and the tub. Should I be putting a little bit more force on it to move it?

The faucet is dripping onto the overflow and leaking from there. I have the below ceiling opened up and can see where the water is coming from.


thanks.

Does the gasket have a groove?

Yes you need to slip it on the brass plate that you show in post#4, and behind the tub. It needs to fit properly though to make a seal.

You took the old gasket out correct? The new one goes on the same way. Did you compare the two gaskets? Are they the same or similar?

I did take the old gasket out, BUT, the old gasket was between the tub and the overflow plate (cover). So on the inside of the tub. Which I assumed was the improper installation. So, I have no idea, what it should properly look like.

Could there still be a gasket stuck on the tub? Feel around.

Felt around the tub and took a look from the below ceiling. No gasket.

OK insert the new gasket fat side down. You did not answer if there was a groove on one side of the gasket, so I assume its flat on both sides.

Yes use pressure to move the brass overflow enough to position the gasket so it sits flush agaist the tub and overflow.

Watch out!! If you drop it its gone......

Then install the trip lever and cover plate. Once you get one screw started the gasket cant fall.

Watch this guy.

Thanks for your help and the video. I guess my concern is that I would have to move the copper pipe about 1/4 - 1/2 inch to get the gasket in. Right now it is flush nearly against the back of the tub. If I move the pipe that much would I break the pipe or cause damage anywhere else? Thanks.

I just want to make sure that if I move the pipe that much I won't break it. I have to push it up to .5 inches backward to get the gasket in.

Sure do what you need to. If the pipe is corroded and it does break you said the cieling was open. I would replece the whole waste and overflow with PVC.

If you loosen the nut where the overflow tube goes into you may get more movment. But then you may not be able to tighten the nut back and develop another leak.

Thanks for all your help. I made a wedge from some old wood and slowly wedged it from the hole in the ceiling between the pipe and the tub with a hammer to create some space. I got enough clearance and installed the gasket. Hope I didn't create a leak in the process. Really, really appreciate all your time and help.

Thanks Again
-Joe.
