blue-green crystals forming at gas water heater junctions
 

Our heater is about 6 months old. We knew the inlet pipe had a tiny leak
and have been watching it hoping impurities would fill it up. Instead a
soft crystalline growth is forming at several places on the heater and
downstream as well.

My husband, a competant handyman and mechanical engineer did the install
and We would like help figuring this out. Could the heater sacrificial
anode be malfunctioning? I believe all pipes in the house are copper or
iron.

We are also experiencing a pressure drop in the hot water lines only.

Hate to say this, but he can't be too competent if he allowed a small leak
to continue hoping it will go away on it's own. Sometimes they do, but
typically its only after the pipes experience accelerated rusting/corrosion.

You didn't describe the situation that well, what is the inlet pipe made
of - iron or copper? What are your hot water pipes overall - iron or
copper? Those two answers might help us better understand it.

I have used 2 paRT EPOXY TO STOP MINOR LEAKS.

iTS REALLY BETTER TO TAKE IT APART AND START OVER the corrosion may be
attacking the tanks connection area.

Dieelictric unions are a good idea.

If the lkeaks at the tanks connection and you dont fix it one day soon
you will need another new tank:( Have that one pro installed its
cheaper than buying another new tank:(
