We started performing water heater flushes as a service to our clients recently.  It has been interesting to see how much we have been able to get out of most of the water heaters.  Most water heaters in this area that are not using softened water are quite gross inside.  Some of them will not flush because there is so much build-up of sediment inside.  Those that would flush, had a great deal of nasty brown water that came out.  We try to flush it until the water comes out clean.  With a good softener, this was usually only a gallon or two of nasty stuff and then it was clean.  Without a softener, there has been 20 to 30 gallons of nasty brown water that came out before it cleared up.

Some people have been frustrated that we could not flush their heater, and tried to blame the problem on us.  Everyone in Southeast Idaho should be aware of the fact that without a functioning, properly sized, water softener, a water heater will build up with sediment rather quickly.  Within one year, there is likely to be so much sediment inside that it cannot be flushed because the drain is plugged with sediment.  Having this sediment build up is costing more electricity and or gas to heat the water because it first has to heat the sediment.  Sediment acts somewhat like an insulator keeping the water from heating as quickly and efficiently.  The sediment also becomes a breeding ground for disease that can make people sick.   It is important to keep a working water softener in areas with such hard water as ours.
