I turn on the hot water tap for my bathtub, giving it maybe half a
turn, leaving it until the water is hot. I then turn on the cold water
tap, and only have to turn it a fraction of an inch or so before the
water is warm. If I turned it as much as the hot water tap, the water
wouldn't even be warm, it would be cold. What is the problem and how
can I fix it? (It's been like this for ages, and the distance you have
to turn the cold water tap before the temperature is optimum is
getting less and less.)


Your hot water feed path may be more restricted than the cold one which
can produce the kind of results you are seeing.

Put an empty bucket under the bath spout and time how long it takes to
fill it with hot water with the cold tap closed and the hot tap fully open.

Empty the bucket and repeat with the hot tap closed and the cold tap
fully opened.

If it takes significantly longer to fill the bucket with hot water than
with cold water you've located the problem.

Fixing it is another (and likely rather expensive) matter.
