Rotten egg (sulfer?) smell within hose down Help!? I have a resourcefully, pressure pump, whole-house filter, water softener and iron...

I have a resourcefully, pressure pump, whole-house filter, water softener and iron filter system. My marine smells horrible! Try brushing your teeth with it gross! What can I do? Is it the hose down heater that's making it smell?
Answers:    you will call for a potassium permanganate water filter system and a chlorine injector put surrounded by the system to get rid of this smell...you will also have need of to remove the anode rod in your hose down heater or your hot hose down will still smell very doomed to failure...
no its in the powerfully, the water is endorsement thru sulfer, , not much you can do about it.
