Installed a Bidet (seat type) and now the toilet fills very slowly

[Deleted member 116079]

Ive replaced the fill valve contraption and flapper inside which didn't help the slow filling problem.
Also tried it without the t valve connected and the toilet fills up perfectly, maybe three times faster.

The T-Valve that came with the bidet seems to be much smaller inside but so do the other ones i would attempt to replace it with.

Thanks for your time!

Have you a photo of tee valve and installation?
