Use your Rusco pre-filter to shock the media or house pipes and heater tank.

If you aren't injecting chlorine or peroxide as a part of your treatment, then using the Rusco pre-filter to occasionally clean the pipes is pretty easy to do:

• Shut off the water.  If you are doing the heater tank, shut the gas/ electricity off

• Open the ball valve on the Rusco, draining the water into a bucket or through a hose

• Unscrew the housing, remove (and clean, if dirty) the cartridge.

• Close the ball valve, and fill the housing with chemical* 

• Screw the housing back in.

At this point, you will be sending that slug of chemical in the Rusco to one of three places:

• backwashing filter tank, to clean and restore media

• cold water pipes in the home

• heater tank and hot pipes in the home

To Send the Chemical into the Filter Tank:

• simply open a tap after the filter for just a few seconds, as the filter (usually an iron filter) is right after the Rusco.  The chemical will get into the tank where the media is, and you let it soak a few hours and then backwash it out.

To Send the Chemical into the Heater Tank and Hot Pipes:

• If there are any backwashing filters, softener or post filter cartridges in housings, the filters must be bypassed and/ or the cartridges removed.

• Open a hot tap and leave it open for a couple minutes- the slug of chemical will go into the tank with "new" water and you are getting rid of the hottest water.

• Stop and refill the Rusco again.

• Now go to each single hot tap and open for 15-30 seconds.

• Let the chemical sit in the pipes**

To Send the Chemical into the Cold Pipes

• Bypass any filters, remove any downstream cartridges

• open each tap one at a time for 15-30 seconds

• Let the chemical sit in the pipes**

Notes:

 * , **   Chemical is usually going to be hydrogen peroxide or chlorine

• Use chlorine and let it soak many hours, for iron bacteria, especially inside an iron filter tank, but also if the pipes are old and have years of biofilm on them

• Most sulfur odors you want to use peroxide and you only need an hour or so to soak

• It is often necessary to repeat the whole process a few times, to get all the pipes up their taps.
