Out toilet cistern is overflowing. The plastic assembly that contains the float and valve mechanism seems to be shot.. Its marked (in italics) on the top of the internals "impulse"
Anyone know where I can get spares for it? Ive googled, but to no effect :(
Wickes/B&Q. Just buy the same kind of float valve.

The innards of cisterns are failrly universal - so you can use generic replacements - they don't have to be the same make as the originals.
Ball valves come in two basic forms - conventional (long arm with large ball on the end) and Torbek (diaphragm valve with very small plastic float) - with a further sub-division depending on whether the cistern is side or bottom entry.
If you remove the existing valve and take it to a plumbers merchant - or even B&Q - you shouldn't have any difficulty in getting something to fit.
You'll probably have to buy a new unit. It's possible that it's repairable - look for a string of PTFA or solder or something comung out of the pipe and stopping the valve from closing properly, or wear of the washer (B&Q, ironmongers for new washer), or problems with the nose of a plastic cone in the valve - I have seen these with crevices on the seating surface, which you can just scrape back a fraction to get a proper seating again. You'll probably need a new unit, though. Make sure that the existing float will screw onto the new arm! They're not dear.
And the Fluidmaster type, with a doughnut float that rides up the pole.

OK - *three* basic forms - I missed that one!
...and the ones with a ball come in two flavours. Those with a diaphragm and those with a piston in tube.
usually it just needs a little rubber disc in the fill valve, 30p or less.

Are there different types of the conventional ball valves?
The reason I ask, is that I recently replaced the ball valve for my parent's cold water tank. I put in a conventional ball valve.
Now, whenever the tank is filling, you can hear a loud noise at the kitchen tap and below the cold tank (where the cold water main obviously runs up the wall). It's as though you can hear the water noise, but amplified.
They never had this before.
I've swapped the little white nozzle inside the mechanism to make sure it's for high pressure (which is was anyway!) and this has made no difference.
Any ideas what I can do to fix this problem?
