Install Water Heater Odor Killer on the inlet to the water heater using 3/4" pipe nipples (can be ordered as an option) to your existing 3/4" flex Line already on your water heater. Fill with store bought 3% hydrogen peroxide. Turn water back on and run hot water in house until you notice bubbles. Let sit for 4 to hours.

  • Installed on the cold line to the water, it can be used as a convenient way to add hydrogen peroxide or chlorine bleach to the water heater, which will instantly eliminate sulfur odors in water heaters. Unlike regular plastic pre-filters, the Rusco Hot Water Filter is chemically resistant, and not affected by higher temperatures, should any hot water back up into it.
  • It is easy to install and needs to be on the cold line leading to the water heater.Includes 1/2" manual flush ball valve.

Here's how it works:

  • Shut off water before the Rusco Hot Water Filter and open a hot water faucet after water heater

  • Turn water back on and run hot water for several minutes
  • Allow water heater to sit for 3-4 hours
  • Odors are GONE!
  • Kills bacteria in water heaters
  • Eliminates odors and slime build-up
  • For most water heaters we recommend the 3/4" 60 mesh size Rusco Hot Water Spin Down Filter
  • Kill Water Heater Odors fast and easy with peroxide or chlorine bleach (peroxide recommended)
  • Safe non-toxic peroxide breaks down into oxygen and water after killing odors
  • 3/4" strainer screen installs conveniently on your water heater inlet


  • Rusco Hot Water Filter (60 mesh 3/4" NPT thread works best)
  • Stainless steel screen
  • Chemical Resistant - peroxide or bleach won't harm housing

water heater odor killer

Hello - I finally had a plumber come yesterday and install the spin-down hot water filter I got from you in order to add Hydrogen Peroxide to our hot water tank in order to solve our odor and stain problem.

Installation was easy for him and I loaded it with the hydrogen peroxide - one time - and the odor and stains disappeared immediately.

Immediately - like magic. Thanks so much - we have been living with this nightmare for a couple months now and were so hopeful it would work. I had no idea it would work this well. Thanks again.

We were quoted literally 2K to filter out sulfur in a hot water heater. Replaced the anode rod with aluminum one and installed this device. Used one shot of hydrogen peroxide and the smell has been gone for almost two months!
