EMAIL = Subject: fleck 5600 as an iron filter
I recently installed a Fleck 5600 from you set up for a green sand filter. Within 3 months the injector, brine valve and valve ports were plugged from Iron fouling. I cleaned them with a mild acid solution and got them relatively back to new. I am unable to draw adequate vacuum when regenerating. I need to order new parts but am wondering if there are any tips you may have to avoid the frequent cleaning/replacement of the parts. My source well has an Iron content of 2.5 PPM of Iron. and is set up to regenerate 2x per weak. Thank you, Chris
** Very typical because of the iron and organics we have in Florida water.
When I use to service these type units in Okeechobee area, it was common to have to clean or replace injector sets every 3 - 6 months.
The replacement Injector for the Fleck 5600 or 2510 is the # 2 PVC,
Injector Nozzle and Throat Sets Fleck Valves
*** Other things you could do:
1 ) Clean ( dump ) the old Potassium Permanganate out and start "fresh". A lot of oxidized iron builds up in the "feeder" tanks over time.
Tank Feeder for Potassium
Pad Felt Pad for standard Potassium Feeder = N1043
2 ) Use "technical" grade Potassium Permanganate, and not "free flow", IF available in your area.
It cost more, but is less likely to clog valve. And we currently do NOT sell any potassium permanganate.
3 ) Do not use the Greensand Filter, if it's just for Iron Removal.
A water softener can remove the 2.5 ppm iron.
But if this unit is also used to remove any hydrogen sulfide odor, you would need more than just a water softener.
see: System Recommendations
Odor - Sulfur (Hydrogen Sulfide) in your water
4 ) I'd be careful using acid, as it can make the injectors brittle and fail ( I know from personally destroying injectors soaked in STRONG acid solution ).
5 ) Also... how old is the Media? Typically "life" in Florida is 5 years ( I've seen 2 years - 10 years, depending on the application ).
It could be the media in the tank is "loaded up" with too much oxidized iron that it has not been able to "flush out" during Backwash cycles.
