I just returned from holiday and I may just becoming paranoid but my system appears to constantly have a rushing water sound when the hot water comes on. I swear it never made it that noise beforehand.
I have a potterton boilder in the kitchen, the two water tanks in the loft, and a hot water cylinder in the airing cupboard. It just sounds like there water constantly running around the system, although the hot water does appear to be fine when I run it, hence me not sure whether I'm imagining something that has always been there.
Another thing I noticed is that there fullway valve at the front of the cylinder which is in the close position and is cold, however when I trace the pipes back either way, about 10 inches away the pipe is hot. Should this valve been open or closed (see photographs).
Any help is appreciated.
