Q:Can you flush two water heaters with one solution
by|Nov 6, 2023
1 Answer
Answer This Question

A:  The acidic property of the solution breaks down over time. Therefore, I would not reuse the solution as its efficacy will be diminished. However, a plumber I have learned that water quality varies tremendously by location. In some locations scaling is so prevalent that scale needs to be dealt with annually and in others where it never builds up. I don’t descale a piece of equipment except when its decreased performance requires it. If the unit is performing properly, I don’t perform an unnecessary descaling process.

    Answer This Question

    A:  It is hard for me to give you a definitive answer based on such limited information so you may want to give me a call so that I can get specific information about your home. Water heaters do not make water smell. The heating of the water may exacerbate odor, but it does not cause it. Odor usually stems from containment in the water. Bacteria can feed on this contaminant and give off sulfurous selling gas as part of its waste. The heating of the water can excite the bacteria and make the problem more noticeable. I have also run into situations where contaminant in the water reacts chemically to other materials in the water heater, such as an aluminum or magnesium anode rode and gives off a noxious odor. In this situation bacteria are not involved; the process is purely chemical. The solution to these problems depends on the nature of the continent. You can certainly have the water tested to find out what is causing this and what is involved in its removal. But I would start by speaking to your neighbors or the water department. Chances are your neighbors will have the same problem and that a best practice to solve the problem has already been established. If you are on a well, I would speak to one of the prominent well drillers or sellers of well supplies in your area, they should also be very familiar with the water in your area. I have run into situations where the solution has been as simple as changing the anode rod in the water heater, or decontaminating a well with bleach to others where a series of filtration devises has been needed. But let me reiterate, I have never run into a situation where the water heater was the cause of the smell. The source of the smell has always been the water. A parallel situation is what is called “soap scum”. Soap scum has nothing to do with soap. Soap scum is the buildup of minerals found in untreated water onto plumbing fixtures. The solution is not a different soap. The solution is cleaner water. Chris 978 651 3301

      Q:Can you use calci-free in a rheem tankless?
      by|Sep 8, 2022

      Answer This Question

      A:  I am sorry but I cannot give you a definitive answer as I am not an authority on Rheem product. I would suggest you consult you manual on what product it recommends for descaling or give Rheem a call. It would be a good idea to have the model number and serial number of the unit handy. It will appear on the units rating plate.

          A:  Yes, it can be used in all tankless water heaters. Just do a good flush before reconnecting the plumbing for regular use.

            Q:Do I need to use both the descalling product and the flushing product?
            by|Mar 14, 2022
            3 Answers
            Answer This Question

            A:  With this product the term flush is referring to the fact that it is a descaling product. So you would just use this. However, as a plumber I want to also point out what I believe to be a common misconception. Many people seem to think they must descale there units annually. I have found that not to be the case. Water quality varies tremendously throughout the country. With wells it can even vary house to house. I do not recommend prophylactically flushing or descaling units on a set schedule just for the heck of it. Unless of course you know based on prior experience that it must be done based on your water conditions. Experience has taught me that some areas the water quality will require that you do it much more frequently than others. And in some areas it may not be required at all. When scale builds up it will diminish heat transfer as well as water flow. If the water is not getting as hot as it used to or the flow has diminished, this may be a sign of buildup. However when these issues are not present, I typically elect not to do it out of concern that these acids could damage the heat exchanger. Lastly recently I serviced a unit that was still producing plenty of hot water and flow. But it had recently begun to make a howling noise. After adjusting the gas valve with a magnehelic the sound was still present. So the manufacturer recommended that I flush the unit. To my surprise this did correct the problem. It also got the efficiency back to factor settings. I know this contradicts what I have said but I am still reluctant to introduce acids into heat exchangers when it is not needed. If you do use this or other similar products make sure to flus the unit out when done. I will typically hook the unit up to a garden house and run fresh water through it for fifteen minutes.

                    So far so good. It seems stronger than vinegar. The price was fair. Wear gloves and eye protection. I wish the directions for disposal was more detailed.

                    Worked very well in cleaning my Rinnai Tankless Hot Water Heater. Only recommendation is that you follow the instructions specific to your model of heater vice simply using what is written on the Calci-Free container. Though very similar, a longer flush time is recommended along with a more robust back-flush rinse.

                    After only 5 minutes of back flushing the on demand water heater I could actually see some calcium deposits floating around the 5 gal. pail being used to hold and pump the solution. I waited about 2 years to flush the system and after I was done, approx. 30 minutes, there was a considerable increase in the volume and pressure of the hot water being produced. Will do this every 6 months now that I see the positive affect it has.
