toilet flow restrictor

I have a Y connection on my toilet line that feeds the toilet tank and also a bidet. Something has gone wrong with the bidet flow control and the pressure is unpleasantly high. I can lower it by closing off the toilet valve part way, but that makes the toilet fill slowly (and loudly). Is there such a thing as an in-line valve I can put just on the bidet line to lower the pressure just on that line?

I'm sure, but we don't know the size or connection of your current line.

I assume you have a Japanese style toilet seat bidet (a European one you'd just open the faucet less). Check the instructions for your bidet. Some can adjust the pressure. On mine it's one of the controls on the remote.

Put a straight 1/2" FIP/MIP quarter turn valve on where your bidet connects, if your bidet flow control isn't working.

.

Yes, there is such a thing as an in-line valve that you can put just on the bidet line to lower the pressure just on that line. You can use an adjustable T-valve which is an easy way to control the water pressure coming out of the bidet1. Another option is to install an external water filter which can help reduce the water pressure2.

I hope this helps!

The bidet itself should have a flow control lever to control the force of the water. I have two of the least expensive base models and both can control the flow. But I still throttled back the toilet fill valve. Since once I'm done, I'm in no hurry for the tank to refill. However, my toilets do not make very much noise.
