Whitlam Flow-aide Solution, 1 gal

Clearly this stuff worked, the results are in the bucket. I had no problems using it. It worked great! I used it to clean a tankless water heater & I will be using it again next time.

I use this product to clean my tankless hot water boiler, it saves me money, Hiring a tech to clean it is usually around $200 With Flow aid and a pump I can do it once every 5 months for under $40.00, So I decide to buy a gallon which will last a year or so which is a big saving, paid $66 for a gallon and use only 32oz each time which by the time I used it all I saved about $8.00 than if I bought one at a time. so if you have to flush out your tankless hot water system save yourself money get a pump for under $65 and Flow-Aid and stop paying the high price for a tech to do it.

This is the best de-scaling solution I have ever used. If your looking for the best this is it.

loosens and cleans scale fast compared to vinegar

Tried this on the tankless water heater instead of vinegar. It really cleaned it although I did it twice for an hour each. With the gallon size I was able to make enough for two batches of product. Clean, rinse, clean, rinse, rinse. The prefilter is how I could tell. It has a wire screen that was brown as if it was rusted. After the treatment it looked brand new. Not as inexpensive as vinegar but it definitely does the job.

I live in a town with extremely hard water that clogs up everything. After installing a tankless hot water heater over a year ago I needed to descale my unit. I mixed up a quart with a gallon of water (1:4 ratio) and using a sump pump recycled it for 45 minutes. There was immediate hard water deposits that came out but over the 45 minutes all of those deposits dissolved into clear liquid. I'm certain that the inside of my unit is squeaky clean.I have seen reviews were people think this eats their metal but metals other than copper do not hold up over time. I suspect this descaler removes the deposits and rust exposing the weak components.I am very happy with the quality of this product.

My plumber used this to service water heater and descale the boiler. I bought some to try on hard water deposits on the shower wall and all the sink and shower fixtures. This is the best stuff! Put about 1/4 cup in a SS bowl and add 3 drops or so of good dish soap such as Dawn, then put about 3/4 cup of warm water. Use a latex glove and dip a scrubby in and wipe on faucets and go over for about 30 seconds. If thick deposits, let it sit for a minute and then repeat. Then wipe off with a wet cloth. This stuff is so much better than any other way to do it!! May not be the purpose on the label, but boy does it work.

I have used Whitlam Flow-aide Solution for several years to clean and flush my electric tankless water heater. I use a half-gallon diluted with one-and-a-half gallon of water and run it through a submersible pump for 45 minutes. Then I flush out the five-gallon bucket and repeat the process a second time. This stuff works real well. I have high calcium water and this product flushes all the deposits out of my water heater. My water heater has been running efficiently now for close to seven years. Excellent product.
