Thank you for contacting Biobidet Support.
You will need to connect the provided T-Valve to your cold water shut off valve at your wall/floor.
The provided water supply hose will connect to that t-valve then to under your toilet tank. The other provided water supply line will connect to the open end of the tvalve to the bidet.
I have provided the A7 instruction manual for your reference as well on page 7.
IF you cannot remove your provided water supply line, you can use yours but will require another t-valve in 7/8".
Let us know if you need further assistance at email@example.com
