We have a water tank in our loft that we turned off the mains supply to it, emptied it out, then when it got basically empty and just trickling through, we turned off the gate valve too. Did the work, opened gate valve, filled tank, all good, until we realised the pressure is none existent now to the cold taps, with the pressure only coming from the water built up in the pipes, and after a few seconds, this goes and you end with a trickle, but say flush the toilet and then turn on the tap, there's nothing coming to the tap.
First thought was gate valve seized up, however it freely moved the entire time, no stiffness, and you can see it raising up and down as you screw it. You also can still stop the water flow when losing the valve, and then open it again, though that's not to say it gets stuck when just a tiny bit open, I assume I'd feel resistance?
An idea is that, when the tank was emptied, could bits of debris from the bottom of the tank, now get sucked into the pipe and cause a blockage, letting only a tiny bit flow through?
If so, my issue is the tank is about 30cm max from the ceiling, so next to no access from above, and the height of it is greater than my arms reach.
If it is this, any ideas how I could unblock it? Thought maybe to push water up the pipe backwards, though no idea how'd I'd do this. There is a mains feed running right near the cold water feed to the taps.
If not this, any ideas what may have caused such a drop in pressure?
Thanks for the help
