CHLORINATION PROCEDURE

 

 

 

 

CAUSE

The chlorination procedure is used to eliminate various bacteria that

 

accumulate and grow in water heaters. These bacteria often cause odorous

 

or discolored water conditions.

 

 

 

 

PROCEDURE

Please read the steps of the chlorination procedure prior to beginning. If you

 

feel uncomfortable performing any of these steps, contact a service person to

 

perform this procedure for you.

 

 

STEP 1

Turn off the gas supply to the tank.

STEP 2

Turn off the cold water supply valve to the tank.

STEP 3

Open a nearby hot water faucet to relieve the vacuum.

STEP 4

Drain all the water from the tank (a water-hose may be needed).

STEP 5

Remove the anode rod(s), and close the drain valve.

STEP 6

Using a funnel in the anode opening add one gallon of household chlorine

 

bleach (e.g. Clorox or Purex) for every 25 gallons of tank capacity.

STEP 7

Reinstall anode rod(s) after inspecting and replacing as needed.

STEP 8

Open cold water supply valve and refill the system. Then draw the water to

 

every hot water fixture, until the smell of chlorine is detected. Operate dish

 

and clothes washers until a noticeable amount of the chlorine is detected as

 

well. All hot water lines must receive treatment.

STEP 9

Leave the chlorine solution undisturbed for one hour or more.

STEP 10

After the contact time has elapsed, drain the tank according to steps #2, #3, &

 

#4.

STEP 11

Close the drain valve and refill the tank. Allow the tank to sit for 15 minutes.

 

Repeat steps #2, #3, and #4. Continue to flush the tank if the water is

 

discolored or contains a chlorine odor.

STEP 12

Close the drain valve and refill the tank. Flush all chlorine from the piping by

 

opening every hot water outlet/ appliance.

STEP 13

Return hot water heating system to service by following the recommended
