I think its called hammering. There is a device called a 'water hammer
arrester' that I think will solve this for you.

Water heater. Esp gas heater when firing.
The momentary drop in pressure allows little
"explosions" in water at the bottom (usually in
calcium deposits).

Not harmful in itself, but could indicate
heater hasn't been flushed regularly.

If he's flushing with hot water, that is the right answer. If he so
challenged as to recognize that, its water hammer and can be solved with an
over the counter hammer stop or just solder in a few 12" long peices of
copper pipe capped off. The air these pipes contain is enough to act as a
shock absorber.
