What the product is and who it is for

Metra Severe Clog Relief is a 5X concentrated cleaner formulated with proprietary enzyme technology for HVAC condensate systems. It targets stubborn organic buildup inside A/C drain pans, drain lines and condensate pumps to restore clear flow. The 8oz bottle suits homeowners who want a professional-strength, DIY pour-in solution for slow or blocked drains without special tools. It is not for buyers needing a larger volume for multi-unit servicing or an automated dosing system.

What the bundled accessories

The product ships as a single 8oz bottle with no additional accessories, dispensing hardware or software included. Because the concentrate is designed for direct pour-in use, the absence of extra items means the user must supply their own measuring container to portion the required 24 oz for drain lines or 23 oz for pump boxes. No installation kits or treatment schedules are provided in the package.

Practical limits of the standard

The enzyme formula requires a dwell time of 4560 minutes in drain lines and at least one hour in condensate pumps before system power is restored. Monthly maintenance calls for a 6 oz dose, while complex plumbing layouts may benefit from bi-weekly applications. The non-corrosive chemistry is safe for standard HVAC materials but the product does not address mechanical damage, collapsed piping or inorganic blockages that enzyme action cannot dissolve.

Questions about this item

How often should I treat the drain pan and line to prevent future blockages?

A monthly maintenance dose of 6 oz is recommended; for recurring issues caused by complex plumbing layouts, bi-weekly applications may be beneficial.

What limits how well the enzyme formula works on a severe blockage?

The product requires a wait time of 4560 minutes after pouring 24 oz into the drain line opening before restoring A/C power to allow the enzymes to break down the buildup.

Is the concentrate safe to leave sitting in the condensate pump and plastic piping all day?

Yes, the non-corrosive formula is safe for standard HVAC materials including A/C drain lines, drain pans, and condensate pumps.
