Both the 5600 and 2510 use the same pilot tube assembly o ring and ring clip... and if there is the 1.05 why would one need to change distributor tube?

A high pressure spray nozzle will work in putting down into the media tank and stirring up the media.. now it is best done out side for the over flow of water from the media tank is going to make a bit of a mess of things ..

There is not that much of iron, I am looking at a system that has 15ppm of iron and 2.5ppm of Mn........ that in years is going to be fun changing and there is really no way around the mess that it will be.

All good comments. It was suggested to me to add a line that goes directly into the intake line for the filter when I make my changes and then use it as a method for introducing bleach directly into the media. This would allow for a cleaning and keep from having to go through shock treating the well. Also, I would not have to deal with the dumping and reintroduction.

Sounded pretty good to me. I am not exactly sure how to do it, but I'll need a shut off valve and I assume a "T". Has anyone done this before? Also, still looking for advice on the DLFC size for Filox...10,12 or 15?

There was a 2510 that used air rather than salt and the line that would have gone to the salt had a 3/8 check valve on it, that line could then be added to and chlorine pulled in through the line...

Back wash rate for the 1 cubic media is 11gpm and 2 is 15gpm. What size tank is in use now?

10". I have read that it needs to be anywhere from 10 - 15 GPM depending on water temp, tank diameter, tank design, amount of media, etc....I was thinking 12 or 15. Since my iron is not attrocious, I was leaning to 12.

Ja, lots of factors to consider. The amount of media for a given tank size will determine the freeboard. The higher the backwash rate, the more freeboard may be required. Back when my iron filter was new, I could shine a light through the tank and see the media well up during backwash. After I had the media rebedded, I was getting media up into the journals in the head due to insufficient freeboard.

A tank of 10x54 is going to be 1.5 cubic with 17" free board.......... really no matter what the media is.

Backwash rate is then on the media... risen lower while kdf will be high... 20gpm.
The current media in question is a cross between pylox and greensand so about 12gpm should do good.

As for media into the valve, either to much or if Pumice/filtag going into back wash while the media was still to fresh and no cap had be made on the top of the media.

That could have been the case.
How long from the rebed to the first cleaning?
just a few hours or more like 10 days with the loss of pressure at any given sink?
