Review: This works when vinegar leaves buildup! - I’ve been using vinegar every year for 7 years on a tankless, but flow has been restricted and not as hot recently. Then the Navien threw a 304 error and flow wasn’t being detected. No particles in filter or trap, but definitely buildup. Tried a 6% vinegar flush for an hour, but no fix and only a few particles cane out in the filter. Could hear pump and see flow only with shower on. Assumed a big plumbers bill! I got the Flow aid descaler within 24hrs and ran it for an hour. It immediately started removing scale into the bucket. Ran for an hour and it looks clear with a few particles in the now spotless filter. Pump came on after restart and error cleared with full recirc flow! Saved me hundreds if not thousands in repair! I’ll never use vinegar again. This stuff works! Review: Shows a color change when completed. - Used on a Rennai tankless water heater that was 18 months in service on city water. Flushed for 60 minutes. Inlet filter was clean before and after the flush. Flow-Aide doesn’t say on the label, but in does make your flush mix an amber or yellowish color. After flushing for an hour the water was clear or a slight blueish. This shows that the flush was effective. Will be using again in 12 months! ## Features - Non-Corrosive, Non-Toxic, Fully Biodegradable, Safe to Handle, Zero VOC - Quickly dissolves water scale, lime rust and other water formed deposits, restoring efficiency to most all appliances - Certified to NSF/ANSI 60 for use as a cleaner in potable water systems - 32oz bottle (1 quart) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E5P5XFS | | Best Sellers Rank | #21,899 in Health & Household ( See Top 100 in Health & Household ) #307 in All-Purpose Household Cleaners | | Brand | J.C.

I have a pump and a bucket, and I hook hoses to the cold and hot water flush connections supplied with the water heater. The other end of one hose is connected to the pump output, and the other is inserted in the bucket for return flow. I put a full quart of the Flow-Aide in the bucket, then fill with water to cover the pump. Open the vlaves, turn the pump on and recirculate for about 30 to 45 minutes.There's probably other de-scaling uses for this product, but it would likely require a recirculation setup to be effective. **Q: Does this product contain vinegar?** A: The container does not list the ingredients; it does say it is biodegradable. **Q: Can you use this in a washing machine? Dishwasher?** A: Yes, this should be fine for that and the Flow-Aide is: Non-Corrosive, Non-Toxic, Fully Biodegradable, Safe to Handle, Zero V.O.C. You may want to first consult the manufacturer of the product you are descaling but you should be fine. GlobalTowne is an authorized J.C. Whitlam distributor. **Q: Has anyone used this in a regular water heater (not tankless)? We have a 50 gallon with a lot of sediment. Tried vinegar but it didn't work.** A: No. Only used on gas tankless unit. I assume the main potential issue would be the amount you'd need to cycle the right dilution through that 50 gallon tank...and any potential negative issues with the anode tube and elements. I'd find something particular to a tank water heater. Good luck! ## Customer Reviews ### ⭐⭐⭐⭐⭐ This works when vinegar leaves buildup! *by K***N on April 28, 2026* I’ve been using vinegar every year for 7 years on a tankless, but flow has been restricted and not as hot recently.
