My manufactured home has plastic plumbing that bangs steadily whenever
I draw hot water. Not the cold.
I was told the problem was 'loose' pipes, Could that be? Or what
else? I am getting sick of the noise early every morning.
Possible the are loose. Hot water will cause the pipes to expand as the
water goes through and heat them. It may be possible to re-route or add a
couple of elbows as expansion loops to prevent some of it.
Early every morning? Is this just happening in the shower by any chance? If so,
the cold side of the shower mixer (I'm betting it's a Delta) is probably set too
low. Crank it up slightly and that should cure it. The adjustments are located
behind the coverplate. pry off the center cap of the knob, and remove the screw
that holds the knob. Pull the knob off, and remove the two phillips head screws
under the shaft. Pull off the coverplate and you will see the adjustment valves
on the left and right of the mixer. They are operated with a flat blade
screwdriver. The one on the right is the cold water. Just turn it
counter-clockwise a little. You can temporarily put the knob back on without the
retaining screw to test the results. Do not go crazy and turn it a lot at once.
It won't take much of an adjustment to get rid of the drum solo.

No - not just the shower. And no - the house is 5 years old.
I just have lived with it for a long time and now I want to eliminate

Do you have hard water ?
Next time you hear the noise,
go stand by the water heater......
Our water has suspended minerals.
It settles ( and cakes ) in the water heater.
When the water heater kicks on,
it clunks, grumbles and growls.
...no...flushing the heater doesn't get it out.
Could be too loose or too tight. The plastic pipes expand when they get
hot so they move. The need to be able to move yet be securely attached.
You might want to go to the basement and let someone turn on the hot
water and track down exactly where the noise is coming from. If they are so
loose as to flop around you need to secure them better, if the can't move at
all (along their length) then you may need to provide that ability. If you
have long runs and if the elbows are tightly secured that could be a
