The toilet in my upstairs bathroom doesn't flush very well. It seems to have the right mechanics but there's no power behind it; not everything goes away without a 2nd or 3rd flush.
It doesn't appear to be particulary old or anything and worked fine until a couple of years ago.
I have a downstairs W/C that was installed about 4 years ago which works fine.
Do you have any suggestions on what I could do to improve it please?
