Hi All

The pressure on my Megaflow unvented water heater has dropped to almost 0.

My plumber is not able to come out for a few days to adjust the pressure and I have no hot water/heating. I know that he adjusted the black switch/lever and I just want to know if it is ok to do this and if it is anyway dangerous if there is no pressure. I have attached a couple of pictures.

Thanks so much in advance.

Hi canary girl , your boiler wont work with no pressure in it so you have to look for something that resembles this


your may have two black handles or just as in the picture, all you have to do is open the tap/s and watch the dial you have posted the picture of and when it gets to 1 turn the tap/s off

simple really.
