Descale water heater , easy way

[RJ2]

I like to descale the Atwood water heater
Without going through the total system flush hassle .
Very simple process , take plug out , get a nipple to hose brass fitting , smalll piece of hose and funnel , hooked to locking latch As pictured . pour in couple gallons of vinegar . Lower hose after couple hours , it drains out then flip pump on for 30 seconds , put plug back in .
