DIYer, not in the trades
The wife put her foot down and said it is time to replace this 20 something year old system. I rebedded both the iron filter and the softener around 10 years ago and was planning on another rebuild versus replace but she'll have nothing of it.
I don't have any numbers on water test results. The dealer that sold me the current system says he no longer does HP tanks with aeration. The iron filter he now sells takes big gulps of air during backwash to aerate and oxidize the iron. I contacted an out-of-town dealer about a new Patterson style system similar to what I have now and he tried to up-sell me to the same type of big gulp system my local dealer has.
I had another water treatment guy come out to have a look at my system and take water samples. Before he took a water sample, he too was talking about one of those big gulp systems but changed his tune after testing the water and after hearing what I had to say about my system. I am going on the faith that he is honest and we are rebuilding the HP tank and micronizer, adding a second modified* HP tank downstream to work as a contact tank and air separator, and replacing both the iron filter and softener. *We will modify the downstream HP tank by shortening up the AVC so it will hold more water and less air. The only source of air to this second tank is air that might move forward from the upstream HP tank at the bottom of a pressure cycle if the draw exceeds the flow rate out of the micronizer.
We will up-size the 3/4" line out from both HP tanks to 1-1/4" and reduce it to 1" at the iron filter inlet. We will up-size the line after the iron filter to 1" and also the outlet from the softener to where the 3/4" cold line takes off to the HWT to 1".
AFAIK both heads will be the Clack WS1 with the softener being metered. I think the media tanks will be 10x54 which are taller than my existing tanks. They don't fit under the floor due to having just a crawlspace so the will protrude above the floor at the entrance to the crawlspace.
