Rated 4 out of 5 by from Needs a Mk2 version I have been using Fluid master fill and flush valves for years and have found them to be well made and utterly reliable. With the water turned off it takes just a few seconds to change the diaphragm washer in both side and bottom entry models. I was very interested to try these new models for comparison. I tend to use the side entry models for older toilets and loft storage tanks, as they never seem to wear out. The AIRGAP 6000 were purchased to try out in a toilet and storage tank. The easy to remove pressure reduction device fitted into the brass shank of the side and the bottom entry models was a good idea. Keep it in for mains water, remove it for a tank fed system. The delayed fill is interesting as it has an auxiliary float chamber with a tiny hole in the bottom. When you flush the system it takes a few seconds to for the total system to empty, meanwhile the water dribbles slowly out of the float chamber and holds the float up for a short time hence the delayed fill. A word of caution - The so called vortex generator is higher than it needs to be, so it may prevent you using as a direct replacement for the earlier Fluidmaster side entry valve - a very stupid mistake; also when the valve turns off it sends a 100mm water jet out of the top of the valve - not clever!. Needless to say the older model diaphragm washer does not fit these new models. Other than my comments the valves are well made and very quiet in operation
