re: Can I replace this bathtub drain?

Your house have a slab or crawl space?

Ever heard of YouTube? Plenty of videos on this. I just replaced mine in the house I just bought because the old one’s top was broken. The drains themselves simply screw into the pipe under the tub.

You take that tool I referred to up a few posts. Jam it into the old drain, then grab your 1/2 inch drive ratchet and unscrew the old drain from the pipe.

Clean the threads in the pipe and around where the old drain was. There will/should be dried Plummer’s putty all in there.

Next take your new drain. Some new drains come with a threaded adapter if you have a wider pipe inlet. If you don’t need the adapter discard it.

Take some new Plummer’s putty. Just a ball of it about the size of a ping pong ball and roll it between your palms and create a snake. Take that and wrap it under the new drains lip and lightly press it in place to form a seal.

Take the tool used to remove the old drain. Carefully put it in the new drain (you don’t want to scuff it up) then place the new drain into place and start to hand thread being careful not to cross thread. When you can’t hand tighten any longer put your ratchet back on the tool that ms jammed in the new drain and click your ratchet to tighten and start to screw it in. Screw it until the Plummer’s putty starts to squeeze out from under the drain lip and the tub and you feel you have tightened it enough. Do not over tighten. Take your finger and remove the excess putty that squeezed out. All done.
