Our sprayer connects to the supply line, between the wall and the toilet, so it should work fine.
the included valve will turn the water off to the sprayer but still let water go to the tank
it comes with a valve that is easily reached. just flip it up when you sit and then flip it down when you stand.
Yes. I am using this from long time and no leaks. I recommend this.
i believe so but you would need a hot water pipe at the toilet hook up from the wall.
No
You can mount it to the side of your toilet tank or to the wall/cabinet
no it will not fit the shower pipes.
yes there is a bracket that hooks onto the tank.
