Good morning everyone:
Earlier this year I had an Aquahot hot water problem on a '95 Bird. Low
flow was the symptom. I shut off the incoming cold water source, drained
the hot water side and took the hot water input and output fittings apart.
Then using an old Par pump, I pumped in 1 gallon of vinegar until it
started to flow out of the output side then shut the out put valve off
while still pumping and let the Par pump shut off at it's 40 psi point, un
plugged the Par pump and walked away form about 5 hours leaving the vinegar
to sit static.
Returning to the Aquahot after 5 hours, I put the output hose into a
container, ran a cold water source to the input side and started the pump
and opening the valves. The solution coming out was blue/green in color. I
completely flushed the system with fresh water until the color of the water
was clear. Then hooked the lines back up and started the water running in
the coach. No more lack of flow problem.
This procedure should be added to the yearly PM schedule. The Aquahot hot
water is an heat on demand system and the 3/8 copper tubing wrapped around
the heat source will scale and start to plug the anti scald valve.
This may also have something to do with a present problem with the 5.7gpm
65 psi pump run/stop/run/stop. I noticed this happening on the one I
installed in my coach and I found that I had a slight blockage on the out
put side. When I found that problem and repaired it, I had no more problem.
Just some thoughts on that.

Good morning Wallace:
That is true, you did have that idea to begin with and the Factory Aquahot
Reps backed it up. And it worked, even though I was reluctant at first. Of
course, I was also reluctant to "sour" your indigenous water system.
Now, had we added salad oil to the vinegar, it would have made for nice
lunch. The color may have been a little off and clash with the tomatoes
though. VBS
