Hi there,
We tried to replace a fill valve on TOTO Drake II with a TOTO C100 washlet and found it very difficult to screw the metal nut to the plastic fill valve. The space is tight, the T junction valve is also in the way for a wrench to properly maneuver. In addition, we can only use fingers to tighten the metal nut for a little bit before it stops turning.
But when we use a basin wrench to tighten the nut, the other person has to use another wrench to hold the fill valve inside the tank to prevent the fill valve from turning. We worried using so much might to tighten the nut would ruin the thread. TOTO tech support said we can definitely use wrench, but couldn't provide further help to address our issue.
Should we continue to tighten the nut or try something else? We think we can remove the nut and try it outside the tank. If it doesn't fit, then it's fill valve problem.
Considering the tight space and the T junction valve, if anyone has experience with the similar situation, any advice will be greatly appreciated.
Thanks you!
