Hi Terry,
Thanks for your reply. I do have a backflow preventer on my irrigation system. In addition, now I have a backflow preventer/check valve right before my water conditioning system too.

Hi Gary,
Sloshing might be the wrong word to use; maybe stirring. When I was looking at the prefilter as the zones were changing, I could see iron/sediment going back and forth. If I had air coming in, wouldn't I have a leak then? Actually, I don't see that I could have air coming in if I have any type of line pressure. I look at it as the plumbing system is trying to get to some equilibrium pressure as these zones kick on. When I'm using the term backflow, I don't mean that it is draining, but rather just a little movement backwards. Once it seems like a zone valve closes, then the water flows a little forward. Kind of like a pendulum. It's hard to describe what I'm seeing in words....thanks for your reponse
Then the pressure is going to zero as the zone comes on due to the peak demand gpm of the zone's heads being higher than your pressure tank/water service can deliver.Quote:

And recall that water is not compressible so the pressure going to zero psi is not going to cause any water movement without something in the system being compressible, like a garden hose, air operated water hammer suppressors, washer machine hoses, etc..Quote:

I thought someone in this thread said that it should be irrigation sprinklers teeing off of the main and the main inlet continues on to the house; I have the opposite. Is there some length of pipe that is needed from the main to the water conditioning equipment? Mine are in real close proximity. Yeah, I don't know how rusty water or iron could get through the iron bed. It was just rebedded; I had the problem before and after rebedding. Unfortunately, I have been down the path of getting all new and refurbished equipment.
I doubt very much that you have any suction leak there, what you had was a classic back flow situation. The check valve has solved your problem. Did you have an approved backflow preventer installed or just a check valve? Both do the same thing but an approved back flow preventer is as Terry pointed out, code required on sprinkler and irrigation systems. I wouldn't give it any more thought, you have done the right thing.Quote:

The entire plumbing system in the house provides some amount of expansion (and subsequent storage) albeit not much. The sprinkler system was dropping the supply below the house pressure causing a small amount of reversal. The final step of a birm filter backwash is a forward rinse and pack, with an emphasis on "pack". This packing is an important last step and the small reversals were shaking up the pack allowing the filter to be too loose.
Also, there could be small amounts of air trapped in the top of the softener or hot water tank which would increase the amount of "draw down" increasing the amount of reversal. I see this exact same symptom on my system.
Hello All,
I figured I'd close the loop here with an update. It's been almost a year since I had this problem. The check valve isolating my system has worked flawlessly. I ran my outside sprinklers almost every day during the hot summer months. The inside house water was/is absolutely crystal clear. No more draining hot water tanks, dumping ice cubes, and softener/filter regens. I've passed this on to a few of my neighbors. They only have water softeners, but they've been complaining of iron in the water (not to the extent I had) during the summer months. Thanks for the great posts. Hopefully this helps other people.
I don't know how this works so here goes. I have a failed MacCleens iron filter that i need to replace. I also have aquired 3 old softners, one with a fleck 3210 and the other 2 with a fleck 3200. Rather than purchase a new filox media filter, can I use the parts from these and just purchase the new media and gravel, If so, what do I use for the control head,and what do i do with the brine settings, and inlet on the controller?
Fleck 3210 and 3200? that would be what kind of timers are on the valves?
Might there be a photo of the units in question?
It might be that you could buy new media , but what media is a question ...
But I be at a loss on the type of fleck valves that you have.
The valves are 3200/ with manual skipper wheel, or 3210/ with water usage auto set wheel. I also have the original 2510 that is on the old MacCleens unit, that could be rebuilt?
Do you need a picture of the valve body?
Photos would be great... of both the valve body and timer controls on the front of the valve bodies.
2510 is a valve that is in use today so that can be rebuilt with no challenge.
You might wish to start a new thread for this,
Some thing like Refit of Iron Filter
Just a thought.
