I read a series of posts from jweiner regarding "green crystals clogging aerators" and I was wondering if that issue had been resolved, and what was causing the problem. I have the same issue. Thanks!

How old is your water heater? What brand?

We have two and they are both AO Smith - one was installed 1/15/14 and the other 6/3/15. I don't know if one or both are the problem. Our plumber drained one of the two last year and found a lot of crystals. I'd have to check which one he drained. Things did seem better for a while, but now are bad once again.

Hello,  Can you tell us a bit about the plumbing?  Is there a hot water recirculation line on either heater?
Yours,  Larry

I'll have to check the manual - I can't tell. I do know the situation was very much the same as the other gentleman's. Just wondering if that had been resolved.

I do not think the other person ever reported back. That said, whether you have a recirc won't be in a manual. But if you sent us pictures of the top and bottom of the tank, we could tell.

Thank you. I'll do that today. I appreciate the help. I contacted AO smith and they just suggested flushing the tanks every 6 month - 1 year. Does that sound necessary?

It wouldn't hurt, but if it's what I think it is, there is a simpler, long-term fix.

I did send two pics of my water heater in reply to the e mail I received. Don't know if there's another way to send, or if that's ok.

I see you sent them to me. That's OK, but it's better to post them here. For that, hit Post Reply and then browse to where you stored the pictures and upload them. You'll probably need to size them down a bit. The forum doesn't like giant file sizes. Don't send those two again. But I'm interested in the pipe on the righthand heater that runs vertically and parallels the temperature/pressure relief valve drain line. Where does that go on either end? I'd like pictures of that.

I think this is the view you need.

I'm afraid it doesn't help much. That pipe that I described...if it's a recirc line, then one end will probably go to a pump and one end back into the water heater, although with gravity-feed recirc, there'd be no pump. You might go to waterheaterrescue.com, click on Commercial Heaters, and then on Proper Recirc Valving or something like that, to see how these things work.

Hello,  There is a clue in the photo.  Those two insulated lines running vertically in front of the tanks likely go to a recirc system.  Still, we need to see how they connect at the bottom of the tanks.  Backing up and getting a photo of the entire setup would be nice also. :cool:Yours,  Larry

Hello,  I do not see a pump, which means this could be a gravity recirculation loop. I see ball valves on both lines coming down to the drains.  These valves could be throttled down so they are most of the way closed and that can prevent much water and sediment from the bottom of the tanks from being pulled into the system when water is drawn.

Yours,  Larry

Thank you for your help. So you think the green crystals are most likely sediment not a disintegrating dip tube (like jweiner had described)?

Hello,  Good chance!  I don't see anything in the photos to prevent water from the bottom of the tanks from getting into the plumbing. When you draw hot water, it will come from the top of the tank but also will flow from the bottom if it can. Throttling down those two ball valves will slow reverse flow, so sediment must stay in the tanks. Also, you are likely to get better hot water delivery... which could be much hotter, so do be careful  :cool:
Yours,  Larry
