How does the sulfur reduction system work?

The LA30P feed pump injects the Sul-X solution into the water. The solution reacts with the hydrogen sulfide gas in the water, converting it into a solid almost instantaneously. The CBF backwash system then traps the solid hydrogen sulfide in the media bed, periodically flushing itself to rinse this material to the drain.

How often does the filter media need to be replaced?

The media can last 8 to 10 years or even longer and needs to be replaced only if there is a drop in pressure or performance.

What type of maintenance does it require?

The only maintenance required is adding the Sul-X solution to the media periodically (SS0104 comes in a box of 4 one-gallon Sul-X solution bottles). The Sul-X solution is used in much the same way as salt with a water softener. One bottle of solution per month is typical usage, but you may use more or less depending on the hydrogen sulfide level and your water usage. We recommend beginning with one box and determining from there how often you will need to replace the solution.

How would I know when and how much Sul-X solution I need to add?

The LA30P feed pump includes a small, 15 gallon holding tank for the solution. This tank is translucent and has marks for the volume on the side. You will be able to check the solution level by looking at the tank or holding a flashlight against the side to see the shadow of the solution. We recommend adding more Sul-X solution when the volume level drops below the 5 gallon mark. Please note that the Sul-X solution is often diluted with fresh water, so 1 gallon of solution can make 2 to 5 gallons of diluted solution. The manual will include instructions for mixing the solution and setting the pump correctly on-site.
