Help! Installed new closed cistern toilet with push button and flushes fine. Then after about three minutes the inlet valve begins to run water again and there's an horrible screeching noise a minute or so later. I have adjusted the level but still leaks noisily after a while. Could it be to do with something called a filter restricter - it came in the pack but I didnt bother fitting it because never needed on my previous toilet?

I'd appreciate any help. Thanks...

Unlike your old float valve which will have had a high pressure nozzle fitted as standard, modern valves are supplied the opposite ie, set up for low pressure, which is why you need to fit the flow restrictor - to stop the mains pressure from overloading the valve.
