BETTER domed washer for fill valve to bidet t-valve

thingiverse

The domed washer (some t-valves came with flat washers which are a joke and don't really seal the connection) I've created makes for a better seal against leaking. * Make sure you set the washer domed side up in the t-valve. No need to crank down the nut to the bottom of the fill valve tube. Just turning by hand for a good seal, then turn the water on (make sure you still have a small bucket under the fill valve) and check for drips. If you see water leaking, then, slowing tighten until no leaks appear.
