Removing mold in hot water lines.

Turns out my coach had a plugged up hot water circuit drain.  All three outlets flow slower than the cold side and after removing a hot side fitting from the manablock there is stuff in the system. 

How do I kill it and flush it without damage?

Bob,

What does it look like?  Black mould or lime deposits or...

Vinegar for lime deposits, 33% hydrogen peroxide for mold (don't get it on yourself). I let the vinegar set for a couple of days.

We use CLR for lime deposits can get it at Wally world. Works on calcium, lime and rust build up.

It is white deposits from heating water and will clog faucet strainers.

We remove propane hot water tank's drain plug and flush with wand every 2-3 months. And we are always surprised how much white cloudy water comes out when we use the flushing wand.  We use city water hose with wand on the end.

That is what I thought too, along with hard water mineral particles.  Mine got horribly plugged up.  Several gallons of vinegar later, and taking apart, and cleaning, the water regulator and faucets, things were running better.  I purchased a portable RV Water Softener and the water has been flowing great ever sense.
