JimK Posted July 14, 2018 Report Share Posted July 14, 2018 If it gets bad enough you will see discoloration in the water tank and if really bad you will see and taste the problem. More common is pseudomonas growth which will start as a very faint pink color on the sides of your tank. Other serious organisms can grow and not show any discoloration. If you are using non-chlorinated water, I would recommend adding a small amount of bleach to the tank. Fill the tank and refill and rechlorinate as needed. As you point out the fill hose can be a serious source of contamination that is often overlooked. Even when using clean, chlorinated water, the hose will remain wet inside almost indefinitely. That environment is a great breading ground for bacteria, algae, and molds. When you store your water hose for days, weeks, or months consider sanitizing the hose before use. I have not found a good way of doing this. I make a stout solution of bleach in a gallon or two of water and pour it into the hose. Stretch out the hose so the solution trickles out of the other end.

Pam first noticed something in the ice cubes from our ice maker. That lead to investigating and I found green algae growing in the white hose by removing it and looking. That lead to checking the water line to the ice maker and since it was clear I could see a small amount of algae growing there also. The line went up the back of the refrigerator which was on the sunny side of the RV which I suspect is the reason it showed there first. I didn't find evidence anywhere else inside. In flushing everything I lifted the upper end of the ice maker water supply to avoid putting the residue through it. I then used a jumper to supply 12V to the water valve for it. The supply hose I used a mix of 1/4 cup of bleach in 2 gallons of water and then filled the hose with that and let it stand for several hours, using a different hose to supply the RV.

Second choice is Calcium HypoChlorite. In emergency we used Sodium Hypochlorite. When I retired these were the only chemicals approved for use in potable water. Why use a very hazardous chemical when a gallon of Clorox is so inexpensive and readily available? Actually, most of the places I have been either have or are switching to Sodium HypoChlorite, reason being that Gaseos Chlorine is just damned dangerous. Granulated or Puck form chlorine (Calcium HypoChlorite) is used at a couple of our well sites and on new installations of mains and services due to its relative long term stability and ease of use. Sodium HypoChlorite, in the form that we get for Water Treatment is 12.5% vs your normal over the counter bleach being 2%-3% chlorine. Sodium HypoChlorite loses strength over time but the risks are SO much lower that it is fast becoming the if not already the preferred method of chlorination for groundwater. Surface water on the other hand is often switching to a process called Chloramination due to the fact that Chloramine's do not have the Disinfection Byproduct of Trihalomethanes which is a known cancer causing agent. In short, I would go with the simple method, use bleach, don't try to use other pool chemicals or what have you, bleach is safe, readily available, and cheap. Also I would suggest ordering some simple total chlorine test strips such as http://a.co/bmNyePI to use when you first hook up in order to make sure that the water you are getting has been chlorinated, the reason I say to use total instead of free test strips is because if Chloramination is done correctly there should be no free chlorine. Anyhow, this was my first post here I hope it was useful to someone.

Ray,IN Posted July 15, 2018 Report Share Posted July 15, 2018 Barb, I do not use it to disinfect drinking water, only to sanitize the entire fresh water system(110G) annually.

Yes, but the low amount residual chlorine does not prevent algae from growing in municipal water when exposed to sunlight. As far as I know ALL public drinking water must meet the same standards, whether it's municipal or private well at a licensed CG.

2gypsies Posted July 16, 2018 Report Share Posted July 16, 2018 Sounds like we're not the norm but in 16 years of full-timing and getting water from many different sources and not all municipalities, we never sanitized. We drank and cooked from the tank. Every so often we'd buy a new fresh water hose. We did use good water filters though.

Otherwise, we dump fresh water and fill with municipal water on a fairly regular basis and don’t sanitize. We do dump water and refill when taking out of storage each spring, and then dump the desert water as soon as we get to the coast as the desert water is so high in TDS.

Sehc Posted July 17, 2018 Report Share Posted July 17, 2018 If algae is growing in the water, there is no chlorine residual. At distant parts of municipal systems, chlorine residual can be lost. That is why you see the crews flushing mains. Maybe the camp ground is not so diligent. Quote Link to comment Share on other sites More sharing options...

I drove for just as long before I began to wear seat belts too. Do you ever visit a doctor if you are not sick? Some of us take preventive measures because of things we have learned as a measure of risk management. As a society, we do many things today for both health and safety reasons that nobody bothered with for many years. It just could be that those changes play some small part in the reason people are also living longer today? I sanitize annually now that we are part-time as the rig sits in storage for several months each year and did pretty much the same when on the road full-time. Unless you check the water at every stop, you very likely put well water into your RV from time to time that is not chlorinated as many rural areas use it. If you stop at COE parks, some of those are on well systems that are not chlorinated as is true of some state and county parks. We lived the RV volunteer lifestyle and we did sit in one location for anywhere from 1 to as much as 4 months and sometimes we were using well water. While such wells are tested on a regular basis, they are seldom chlorinated. Edited July 17, 2018 by Kirk Wood Quote Good travelin !...............KirkFull-time 11+ years......

We discovered that when we removed the faucet screen to see why the flow had slowed down. We moved. Be proactive, people.
