I was boarding the loft out and emptied the cold water storage tank to make it lighter so i could get the boards underneath.
I did this by turning the cold water to the house off and running water out the bath. Later turning the cold water on allowed the tank to fill as normal.
This morning the shower didn't work at all to start with, but the bath and sink taps did although not as much water as normal came out, as if there's less pressure. Puttign the shower in the bottom of the bath and running it improved things a bit but it's still poor - any ideas?
I think it may be trapped air but how would that stop the shower working and how do I get it out?
The tank is filling normally.
