Water Still Foamy…even Effervescent like Alka-Seltzer!

Hello again to those who answered my first post named "Foamy Water" back on 8.9.14. We thought we had resolved the "foamy water" problems yet no, now they are back.

On the 8th, we had foamy water coming from all the faucets. Not only foamy, yet effervescent like it had an Alka-Seltzer in it. It also had a light odor, not sulphur, but more of a manmade, chemical odor.

Since the first post, we have move on from the RV Park we were staying. Before leaving, we hosed off the front windshield and when it dried there was a white, "mineral" residue left in all the water drops. So, we thought there may have been a high mineral content in that park's water and that is what had been causing all the foaming water issues. So, before leaving the park, we drained the holding tank and all the water lines and left them empty. We did not drain the hot water tank via the plug, yet did run the hot water until it was empty.

When we tied into city water at the next RV Park, there was a very brief moment of lightly foam water, then it ran clear and continued to run clear for about 24 hours. Then, the foamy water returned, but only in the bath faucet and toilet sprayer. After allowing the water to run for about a minute or so, the water ran clear again and after a couple hours, it's still running clear. The Holding Tank remains empty.

Our ideas to what may be causing this or where it could be originating:

-- Do white potable water hoses go bad? As in the liner breaking down. During a recent disinfecting, we introduced bleach into the holding tank via the drinking water hose as we do not have an outside opening to our tank.

-- Can the lining of the plumbing piping break down? Could some minerals react with the PVC?

-- Is there anything in the water system like in the hot water heater that would cause this? The first time we encountered this, the foaming was in both the hot and cold water. Today, only the cold water was foaming and only in the bath faucet and toilet spray lines???

PLEASE NOTE: Our responses may be delayed as we will be off WiFi and this forum after today 8.12.14. Traveling in Canada and will be in their national parks for the next two weeks w/o Internet connection.

Thanks for all your continued ideas!

Many thanks!!!

  • You may have had some high-mineral water introduced into the plumbing system.

    Disinfecting with bleach may have scrubbed the tank and the rest of the system so that minerals were suspended in the system. If you drained the system but not the water heater, there will still be a few gallons of water in the heater. If you have a Suburban water heater, I would suggest to drain the heater and inspect the anode rod. Some water sources will deteriorate the anode rod quickly and that could also result in cloudy water.

    Good luck with the water and enjoy that good Canadian water.
  • It could be that you had water high in Calcium Carbonate. This is common in wells that pull from a limestone aquifer. In the Black Hills of South Dakota, there is a very short water fall called Cascade Falls. The water originates in a spring about two miles upstream. As the water cascades, the churning releases the calcium and the oxygen resulting in effervescence, calcium deposits, and dense water that makes you float high when you swim. It's kind of neat.
  • It will not be anything to do with the piping. It's inert and can't cause that. I assume you've determined that it's not dissolved air in the water which will precipitate out after a few minutes?

    If it is coming from the hot and cold faucets, it's sounds like something to do with the water source. Do you have a filter of any kind? If so, that could be introducing something into the water.

    With the hot water side of things, the water sits in the tank between uses and you *might* think it's something within the tank. But if it's happening equally with the cold side too, there has to be something in common and about it could be is the source water, unless you have a filter.

    Where are you camping? If on a municipal system, I would highly recommend that you call the local Water District and ask to talk to the manager and have a discussion with him/her. I did that earlier this year in Wa. and got some great info. that I couldn't have gotten elsewhere. If you are on a private system (groundwater or surface water) I would ask the CG if they have any test reports. If no luck, I would go somewhere where you can connect into a municipally supplied faucet and see what happens. Does it happen at home?

    If you are camping in the same general area, you could always get a test done at a water testing lab. May cost around $50 or so but you would hopefully know for sure if it's the water or not.
