Seal it to the back side of the tub? There should be a foam ring that is beveled that goes between the tub and the drain. When you tighten the cover plate down, it compresses the foam and seal the drain.
Seal the hole so that it doesn't work? There is probably a cover plate that is solid and would seal on the inside surface of the tub.
It is the volume of water that the tub can hold until the water reaches the overflow hole.
Its your bathtub drain.
Typically right under the faucet in a bathtub is a round metal piece with holes. This is an overflow outlet. It connects to the bathtub drain. If water rises over that disk, it will go through the overflow...so your tub does not fill completely and overflow the edge of the tub. The overflow prevents accidental flooding of the bathroom.
Forever or until disturbed whichever comes 1st. Probably 25 years or more, but some will dry rot and fall off sooner.
You spelled it correctly, but in case you need it again: Overflow In a sentence: I overflowed my bathtub. Hope this helps! :)
A Porecelator is the American equivalent of an overflow outlet on a bathtub or sink.
As long as it's below the overflow, it's 'correct' .
backsplash or overflow... :)
A quick way would be to drop into a plumbing supply store. They often have tubs on display with the overflow drain hooked up. You will be able to see where the overflow water goes down the drain. Des Perado
So If the main hole blocks the water do not get overflow through basin.
It either goes into the ceiling undetected for a long time Or it can go down the over flow past the stopper and into the drain line depending on whom did the installation
It's a drainage hole so the dam doesn't overflow.
