This is an excellent fill valve. It is quiet in operation, shuts off quickly, and is very well made. The height of the valve is adjustable to suit most cisterns. The PRO45B has a brass shank pipe connection, but there is a cheaper version with a plastic shank. The brass version is worth the extra cost. The one I purchased has only been installed for a month, hence the durability and life is not yet known.

For fitting it is important to understand that the valve mechanism is contained in a housing at the top of the valve, and that the valve fits vertically into the cistern. The float side of the valve requires 75mm clearance from the valve vertical centre-line, and the opposite side requires 25mm.

Before buying ensure that the valve will fit the cistern. The top of the valve is 50mm diameter - so check that there is enough clearance to the side wall of the cistern to accept the valve head (25mm from centre-line to cistern). This was a issue with an Ideal-Standard Studio cistern, causing slight bending of the valve stem, but not enough to cause a problem.

To install in accordance with the water regulations, the instructions advise to set the "critical level" mark on the valve to at least 25mm above the overflow water level in order to ensure that cistern water is not drawn back into the supply. This translates to the top surface of the valve being 75mm above the overflow water level. Check that the cistern and lid can accept the height and diameter of the valve head. The valve stem can be adjusted to be shorter, but it is not recommended to contravene the recommended fitting height and water regulation. If the installed valve height is a problem a better solution may be to lower the overflow water level, and save water as a consequence.

I bought this to replace the plastic thread version as I had inadvertently stripped the threads when installing it. This valve replaced the original ball valve.

I decided that this was a much nicer, neater solution. I followed the instructions to the letter but had to remove and re-drain the cistern once as I had extended it too high and the cistern lid wouldn't sit properly. This also allowed me to adjust the clearance between the float and the syphon as there's not a lot of room in my cistern.

Happy to say it works well and the amount of adjustment both of the overall height and the travel needed of the float for shutoff is great. It's pretty quiet on my high pressure system although I was careful to turn down the inlet valve to make sure in wasn't filling faster than the overflow could drain. The shutoff time is pretty quick, from full flow to off only takes about a second, unlike the older ball valve.

It says on the box that this is for high and low pressure systems and the fill is quiet because it fills at the bottom of the value (near where it goes through the cistern) and as a result you don't hear the water drop from the filler nozzle.

Its nice and adjustable in terms of pipe height and the float height. Also would've been super easy to fit, unfortunately my pipes don't line up nicely as they do on all those youtube tutorials. This meant I had to ensure the bottom was tightened up much more than recommended to ensure the washer sat nice and flat at the bottom of the cistern, to avoid a leak.

I had to purchase a brass backing nut separately to solve my particular problem, but as it has a brass shaft they could've supplied a metallic nut as the threads are less likely to get damaged.

Either way a good problem and sorted out my water hammer problem. Oh it also comes with an restricter which you can optionally fit to further reduce water hammer, I fitted the restricter anyway.

Quiet, fast, it seems to be of high quality and was delivered promptly. Unfortunately, the large central portion is too big to fit beside the syphon in my compact cistern, so the float cap is too high and the valve cannot stop the inflow.

Bought to replace the same valve but with plastic shank, which I was struggling to fit without leaks at the thread and base. The brass shank allowed for better sealing and tighter fit, and was far better than the plastic version. The unit itself I like for the ease of adjustment and quiet operation compared to the old ball-valve type mechanism which was noisy and prone to corrosion and calcium deposit build-up on the metal parts.
