Gravity fed system cold water tank in the loft seperate cylinder in the airing cupboard managed to sort the issue on a short term by putting the mains via hosepipe up the hot trap,however the problem reared its ugly head after 1 bath full of water . The does seem to be alot of miscellaneos debis in the main cold water tank so I clean that out and see what happens however this doesn't seem to affect the cold water supply/pressure upstairs many thanks for the help Brett

it sounds as if you have already cleared any chance of air lock already by running mains preasure water up the hot water pipe so it sounds as if what you have is debris in the pipe. you cleared trhis temporarily by running mains preasure up the pipe but the debris came back down again blocking your water flow. find out if blockage is pre cylinder or post cylinder and treat to clear accordingly.

Sounds like you have an air lock try blowing into your tap. Failing that you need a plumber to try a few other tricks.

Sounds To me that you have got an air lock can be removed by back filling hot from cold main as it is of a greater pressure and will push the air lock back out. If Prob persists after running bath sounds like your storage tank in loft is running out and drawing air in quicker than is filling back up try changing ball valve to see if this helps you can put a Larger ball valve in, this sometimes will do the trick.

Have you checked that nothing has fallen into the cold water tank in the loft?

Hi, Sounds like a tycipcal air lock in your pipe! Has any one been up in the loft just befor it started playing up?Thay may have nocked a pipe and changed it out of its rising direction? If not has the header /storage tank got lids on them?? could be that something has dropped into the tank and is restricting the water into the feed pipe. regards Ashley

had it once with iron pipe that had rusted internally causing slow flow/blockage. Temporary fix was to feed the mains pressure up the hot pipe to dislodge the rust! Then let the water flow till it runs clear.
