I recently purchased a bidet seat/washlet. I live in NYC in a rented apartment, and the toilet is designed in such a way to be fairly shallow - and inflow tube to the toilet tank is very hard to reach.
The instructions for my bidet seat said explicitly not to install the t-valve on the wall juncture, but instead the juncture between the tube and the toilet tank, and so I attempted to do so.
While I was able to attach the bidet (via the t-valve) to the tank, I could not get it without it leaking, nor could I reinstall the toilet connector to the tank without that leaking. After several hours of trying, I called my Super who also had no success, and who eventually called a plumber who came the next day and reconnected the toilet without the bidet attachment. (He, I think, replace a plastic piece that went from the toilet tank to the connector with a longer/new one? But not sure).
Is it possible/advisable to try again, but attach the t-valve to the wall side of the toilet water connector? Do I need a different kind of t-valve for this application?
Thank you, and please let me know if pictures or any other information would be helpful
