how do I undo these hoses?

I added an expansion tank to the TT & used Sharkbite fittings & PEX. For $2 I also bought the disconnect tool.

thanks everyone
we would be lost without you!

And after You do get them apart You will wonder how these can possibly hold the pressure,but they do a really good job!

We use them all the time for quick connects for the RO System and the Watering lines to Our Small Garden. they come in a variety of sizes!

I make sure to release the water pressure first then I use a small adjustable wrench held flat and slide down the hose to depress the ring and make sure to pull hose after depressing ring not before.

Correct answers above...I have a little plastic tool that looks like this to depress the collar so the hose can be pulled out.

See the little collars on the fittings. They need to be pressed in and the hoses will pull right out. If they're hard to press in, push the hose in a bit and they should release....Dennis

Push the hose in then depress the piece on the hose and pull the hose.To reconnect just push the hose back in
