There is water dripping out of the part of the t-valve adapter connected to the toilet tank. The angle required to tighten the bolt with a tool makes it (seemingly) impossible.
Wrench? Not enough space to turn it. Pliers? Too big to reach it. It’s been tightened by hand as much as possible, but still leaks.
Even when I remove the other connections, the problem is still the lack of space to work with.
Any ideas for a solution? Thanks, kind folks.
The installation instructions show a rubber washer in that T connection to the toilet inlet, so once you have it finger tight, it should only need another 1/4 turn or so with the wrench to make a seal.
Tools
There are some specialized tools available for tightening nuts in tight spaces:
One is a "basin wrench" (example only):
More generally, you can get "crows foot" wrenches, which attach to a standard ratchet extension for right-angle work (example only):
Alternate Part Eliminates Need For Specialized Tools
Also, the manufacturer website indicates they sell an "alternate" T which seems to connect right at the shut off valve instead of at the toilet inlet. That may be your easiest bet.
