Fluidmaster Side-Entry Fill Valve ½" is rated 4.6 out of 5 by 131.
Rated 5 out of 5 by from Good and easy to fit This was a very straightforward fill valve replacement. The instructions are very clear for a non-plumber to follow. Once fitted the valve is easy to adjust and quiet in operation.

Rated 5 out of 5 by from Best on market I am a plumber and only fit Fluidmaster fill and flush valves. They are far superior than the Siamp valves. You will be lucky to get 3 years service before the fill valve diaphragm fails! The first sign of failure is the cistern takes ages to fill up. I change them to Fluidmasters and personally guarantee them for 3years. All Fluidmasters are made in California believe it or not.

Rated 5 out of 5 by from Super fast fill up I found this fill valve super easy to install, and set up, great water level adjustment, runs very quiet, and is a fast fill. Overall very pleased and most importantly, the client was happy.

Rated 4 out of 5 by from So far so good This was very simple and quick to fit with the clear instructions provided. Much better than the Flodisasta it replaced, which failed after less than 1 year. It's also so quiet that I cannot hear the cistern filling. Only time will tell if it lasts. My only gripe is that the whole thing twists on its axis at the inlet pipe after it has been tightened. I'm not sure if this is to allow easy, tool-free adjustment of the float's position, but it it seems odd that it can easily be moved by hand.
