We are aware of this problem and it is something we are prepared to handle. We have the T Valve you need, the reason you got the 7/8" is because it is the more common of the fittings.
If you want to reach out to us at (847) 458-2334 or at Support@biobidet.zendesk.com, we can get the right T-Valve fitting to you as soon as we can.
All of our models come under a warranty, and if your unit is still under warranty, we can send out the 3/8" T-Valve under cover of the warranty.
