Its non-fuming, non-acidic formula safely works through standing water to clear grease, hair, and soap buildup without harsh fumes or splash-back. NSF registered and septic-safe, this 1-gallon solution is trusted by contractors for efficient, routine maintenance in commercial and residential settings. ## Description Nu-Calgon 4165-08 Drain Solve is a professional-grade alkaline drain cleaner formulated to quickly open and maintain clogged drains in HVAC and general plumbing applications. Packaged in a convenient 1-gallon bottle, this powerful yet non-fuming solution is designed to clear A/C condensate drain lines as well as kitchen, lavatory, bathtub, and other facility drains where grease and organic buildup can cause backups and service calls. Drain Solve uses an alkaline-based formula that cuts through grease, hair, vegetable matter, soap residue, and other organic debris without the violent eruptions or dangerous splash-back often associated with harsh acid drain openers. It does not contain sulfuric acid, helping reduce the risk of noxious fumes and aggressive reactions that can put technicians at risk. The liquid pours through standing water so it can begin working at the clog source without needing the drain fully cleared first. Ideal for HVAC professionals and facility maintenance teams, Nu-Calgon Drain Solve is widely used to keep air conditioning condensate lines flowing freely and help prevent overflow, water damage, and nuisance shutdowns. It is also a strong option for commercial and institutional environments such as restaurants, healthcare facilities, fitness centers, kennels, and bars where organic buildup and grease are common drain problems. When used as directed, it is safe on septic systems. This product is NSF registered and must be used in accordance with label instructions by HVACR professionals. For general drains, pour 16 ounces into the drain and allow it to work for 15–20 minutes, then flush with warm water and repeat if necessary. For larger drains, use the entire contents and allow it to work up to 30 minutes before flushing with warm water. For ongoing maintenance, apply 8 ounces weekly for small drains and 16 ounces weekly for larger drains to help prevent recurring clogs.

A/C Drain line was clogged badly, vacuuming was not pulling all the slime and sludge out of the line, Added a bit of drain solve, let it sit for a bit, and then, I heard the suction noise from the vacuum connected on the other side of the line when it finally cleared obstruction, flushed with some hot water, and system is draining like a waterfall now. 100% recommend.
