Thank you for contacting Biobidet Support!
I'm sorry to hear the T-Valve has a leak! The correct O-ring should be supplied, and I do apologize that there may be the wrong o-ring.
First thing to check is if the O-ring that was supplied can be flipped over to create a snug fit. A lot of times the o-ring is just upside down.
The T-Valve CAN be connected either to the water shutoff valve if the valve dimensions and threading accomidate. You can also connect under your toilet tank in the same manner as well if it is the correct fit.
If you are still experiencing a leak, PLEASE discontinue use until we can find the proper solution for you. Contact us further at firstname.lastname@example.org
