Unsure how to connect to toilet shutoff valve

I'm trying to connect a bidet to the toilet shutoff valve, but I'm not sure the best way to do it.

Normally, the supply line can be disconnected from the shut-off valve part, but I don't know of a good way to accomplish this. I unscrewed the shutoff valve, and this still leaves the supply line connected.

The toilet water supply line and shut-off valve that looks like this: http://tinypic.com/r/qzhfkn/8.

These 3 pics show the bidet:

Is the stop valve non-standard? Any suggestions for how to install the spray attachment?

You need a new shutoff valve. That one is both old and not designed to separate from the supply.

You do realize that a real bidet mixes both hot and cold water to a very comfortable temperature then washes your private parts. This " bidet " is going to be very cold in winter . Also most bidet come with a vacuum breaker so that it is impossible to siphon out the contents of the toilet bowl back in to your drinking water. I would not touch this job.

Both answers above are true.

You need to plumb (inside the wall) for a new fixture like a bidet, not just tap into an existing toilet supply (cold). You also need to plan for a drain/vent combo.

If you are not familiar with plumbing, call a licensed plumber.

Thank you for the reply. I was hoping to avoid replacing the shutoff valve, but it is my final option.

Appreciate the reply. Without going into too many details, yes... definitely cold, but tolerable. :)

Thanks for the reply. I was hoping to avoid having to go inside the wall, since the cold hasn't been too much of an issue (previous home). I'm not sure it's even possible, but I'd love if there were an option that could use the water supply line to the tank interface.

Actually there are 3-way angle stops available. We use them all the time under the kitchen sink, mainly for hot water to the kitchen faucet and hot water to the dishwasher - from the same source.

But in your case, it's different.

1. All connectors are exposed. Do you really want exposed pipes?
2. The bidet will probably be located too far for a simple connector. That's why re-plumbing is necessary.
3. You need hot water to the bidet as well. If you have a hot water pipe in a wall nearby, you could do it.

In any event, I feel that you'll need some professional help.
