Hello, any tips for finding and replacing blocked water pipes? I am pretty sure the cold feed from our F&E tank to the boiler is blocked, but the pipework is more or less all completely hidden...

Also could it be an airlock? If so are there any tips for sucessfully filling a system again, this one had been drained for 3 years?

nwjr,
Most likely an air lock, do some temporary adaption of the pipework to the F&E tank so you can use mains to clear the airlock.
