Plumbing Q - placement of bathtub drain washer

[JoeM]

Dumb plumbing questions about Price-Pfister Trip Lever Waste and Overflow assembly.

I have a 25 year old cast iron tub. I have noticed rust under the tub at the drain, corrosion on the brass waste assembly, and a leak. I am trying to repair it.

The waste elbow is located under the cast iron tub. A waste plug assembly is located in the tub (the trim you see at the top of the drain). There is a washer between them.

1) Should the washer go under the tub? This is where it is now, but the leak worries me. A Danco part seems to show it above the tub, but this doesn't seem right either.

2) Should I put plumber's putty or something between the waste plug assembly and the tub?

3) Anything special to watch out for in this type of repair or other stuff I should do as long as I am in there?

Thanks,

Joe M

The rubber washer goes under the tub and use plumber's putty around the waste plug. The only tip I can recommend is to be sure that all your mating surfaces are thorouoghly clean before assembling. It should work well for you.

Thanks Jim.

No problem, Joe. I hope you have a spud wrench for the job. It will make the job a lot easier and will alow you to get the shoe seated properly into the female end. BTW - as an added little hint, be sure that you roll the putty in your hands for a few minutes. When it's warm, it will seat a lot easier.

Jim,

Spud wrench? No spud nuts at far as I can detect.

Are you talking about a barbell wrench? This fits inside the waste plug (or shoe) and is used to install remove it instead of plier handles like I am using. The thing looks like a miniture barbell (or dumbbell weight). I've never seen more than a picture and I am not real sure on terms.

B TW, I finally figured out [was told ;>) ] that the plumber's putty forms the seal and the washer/gasket is just there to provide some spring force to keep the shoe against the tub.

Thanks again,

Joe
