Atwood water heater with aluminum tank.....need to do an acid etching.
Vinegar Soak!
Turn off water supply (or bypass water heater)
Drain water heater and reinstall drain plug
Remove T&P Relief Valve
Using a funnel pour vinegar into water heater via T&P Opening
*6 gal tank---4 gallons vinegar/2 gallons water
**10 gal tank...7 gallons vinegar/3 gallons water
Reinstall T&P Relief Valve
Turn water heater ON...let it heat then cool down and reheat 4X
**Do Not use the water....let it heat/cool/soak
Best to let it operate overnight/into next day
AFTER 4x heat/cool cycles
Turn water OFF
Relief Pressure ---POP open T&P
Then remove drain plug and let it drain
When Drained....turn water supply back on (or if bypassed --place back in service) and let it BLAST out of drain hole
Drain/flush couple of times
Install drain plug
Fill water heater by turning water supply back on....bleed air out by opening hotside of faucet
Turn water heater ON.
