DRAIN IV is a HVAC condensate drain line conditioning system that helps prevent bacteria from growing in the drain that forms into clogs. If you live in a climate that you run your air conditioning, you will have condensate that is sent to a sewer drain or the exterior of your home. With aluminum being the makeup on the modern coils, you have a high chance of bacteria festering in your drain line. When unattended to, a clog can form, causing condensate to backup into your system and possibly causing damage to your home.

DRAIN IV can only be purchased from a licensed HVAC contractor. You can contact us and we will refer a contractor that can install DRAIN IV in your home.

DRAIN IV can be purchased by licensed HVAC contractors from your preferred local supply house. Contact us if you are having problems sourcing DRAIN IV.

DRAIN IV is a complementary solution to UVC lights. UVC is a great solution for killing bacteria where the light has direct contact, but UVC does not treat the drain line. We can inject our proprietary solution either into the air handler drip tray or directly into the drain line.

No, DRAIN IV will not need to be uninstalled in colder climates when used with our SubZero Hero Anti-Freeze additive. The DRAIN IV SubZero Hero additive keeps your DRAIN IV system working year-round and prevents freezing in the DRAIN IV pump, bag and tubing.

DRAINIV-CON-8.5OZ concentrate solution is a proprietary agent that is acetic acid based along with other compounds. Our concentrate and other approved fluids must be used to avoid damaging the system and voiding the warranty.

Only our proprietary concentrate, DRAINIV-CON-8.5OZ should be used with the DRAIN IV System to avoid damaging the system and voiding the warranty.

DRAINIV-CON-8.5OZ concentrate solution is to be diluted with tap or bottled water.

Empty the DRAINIV-CON-8.5OZ concentrate solution into the 1-gallon IV Bag and fill within 1” from the top of the neck with water. See bottle instructions for details.

PH range of the diluted DRAINIV-CON-8.5OZ concentrate solution is 2.3-2.4.

DRAINIV-CON-8.5OZ concentrate solution, when diluted, has a PH of 2.4-2.6 which is acidic on the PH scale. Most coil/pan cleaners have an alkaline PH which when mixed, will result in a PH somewhere between the PH’s of the two products. Please contact your coil/pan supplier for information about their product safety. Do not mix with strong oxidizers, acids and bases. Do not use without diluting.

For Contractors, DRAINIV-CON-8.5OZ concentrate solution can be purchased at your local HVAC supplier.

Homeowners with DRAIN IV installed should contact their preferred HVAC Contractor to order the refill concentrate solution.

Yes, the diluted concentrate is safe for septic systems. It does not harm the beneficial bacteria within the system and can even help break down soap scum and grease that might clog pipes.

The solution we use is a gentle acid, much like household white vinegar, applied at a safe dose of 30ml (1 oz or 1/8th cup) every 2 days. This amount mixes with condensate from the coil in the drain trap, becoming even more diluted. Rest assured, by the time it flows out of the drainpipe, it’s completely harmless to animals!

6 months is the recommended refill schedule. However, we designed the system to have extra fluid so that the IV Bag doesn’t run out if servicing is slightly longer than 6 months.
