Air trap after loft tank cleaning

[Atiyaa]

After cleaning up of loft big tank, water supply has stopped for taps due to bubble trap. How to release please?

Do you know if the distribution pipes were plugged in inside the tank during cleaning? Could it be dirt getting into the system?

Two ways.

1. Back feed with mains pressure, ie connect a hose from a mains tap to one which is fed from the tank - this will push the airlock back into the tank.

2. Use a wet vac on one of the tank fed taps, this will pull the airlock out of the tap. This method is easiest. Create a good seal between vac hose and tap using a damp rag, keep sucking until your vac is full then pull the hose away and water should continue to flow. May need to do it a couple of times if it’s bad.
