6It did the job I needed.
No fuss getting it set up, and the fill sounds better.
A solid replacement. Everything seems to be working well.
The tank fills quietly now. Nice and simple.
Much quieter
Glad to have the noisy refilling sorted out.
Works as expected, and the adjustment was straightforward.
