Its just started happening and i HAVE NO IDEA WHY, I also noticed the
shower is driping as well, might be something to do with it. I am
going to ring a plumber to get it fixed, but would like some feedback
to see what you guys think, pretty sure its out of my league to fix it
though.

I can get full power On the cold water just fine, but when I turn the
hot on inthe shower it has no power at all. I adjust the hotness of
the shower now by turning the cold down.

I did a google and some have said it might be the ho****er line to the
shower and its just gunked up with stuff and a clean out of the line
is needed.

Thanks for any info.
