ᐅ How to open a floor drain in a laundry room

Hello everyone,

In our single-family house (built in 1965), we have a laundry room with an old floor drain. I wanted to remove the grate to take a closer look at the condition of the drain and to see if a backwater valve might make sense here. However, I can’t get the grate off; it’s stuck very tightly. Does anyone know how I can open the drain?

Thanks and good luck,
Andreas

I would try using a very large can of WD-40 and a lot of time...

I would try using a large rubber mallet. Just hit it until it comes loose.

If it doesn’t come loose, I would carefully use a rotary hammer on the edges. That should do the trick.
