Hi, I've got a Glow worm swift flow 80. Last night the pressure dropped to 0 and couldn't get any hot water. In the instuctions is says to turn it off if its below 0.7. Can anyone help and tell me how to fill it up or repressurise? Have just moved into our first home so not very up on central heating etc.
Any help will be much appreciated.
Thanks
Dee
