what is this?

[Bluemoon64]

Wondering what this is and if I need it or can I take it out. There is a attachment to hook up to the water supply but it is not hooked up. Any help would be appreciated.

OK every time I try and add an attachment it crashes so I will try to explain....
Round tube sticking up directly behind toilet seat. The top twists off. Is it a way to supply the toilet bowl with water other than the sprayer?

That part is called a "vacuum breaker".

What is its function? Do I need it?

Definitely essential for proper operation. Do no remove. I keeps a vacuum from building up in your system.

Sorry about the spelling, blame it on not double checking the spelling checker.

Welcome to the forums.


It lets whatever plumbing it is connected to suck air into the pipes, without letting fumes or liquid from the pipes back into the living space.

They are used in various applications. One common spot is a faucet, to prevent a connected hose from holding water when the faucet is turned off.

If it was connected to the commode, perhaps it allowed the water trapped after the flush valve to drain into to the bowl? Just a wild guess.......

But, if I am reading your post correctly, it is not connected to anything now?

It should be connected to the drain line of the black water, or directly to the black water tank. It lets air in when the tank is drained, or the toilet flushed, to replace what is draining out.
