Water Tank Sanitization
Most people tend to sanitize RV Water holding tanks with Bleach, if they do sanitize. I try and stay away from bleach in all aspects as there is mounting evidence that it's not the best for us, from inclusion into city water (taking a shower in chlorine gas, eww), to just being around it more often. Bleach does have some good aspects, such as killing bad germies. There are other options to killing bad germies though, better options depending on the intended application.
To sanitize my tank, I chose to go a more environmentally friendly route, using Hydrogen Peroxide. One of the keys to using Hydrogen Peroxide is to use the 35% Food Grade version. The typical stuff, in the brown bottle, from the drug or grocery store, just won't cut it, no pun intended.
I used this article as a general guide for how went through the sterilization process. One thing I didn't do is add lemon juice. As it's slightly acidic am sure it would've helped, but my thinking is Hydrogen Peroxide is corrosive to begin with so that should be enough to do the trick.
Got my bottle of the Hydrogen Peroxide from Raw Vegan Source, quite some time ago, to use as a vegetable wash. For a vegetable wash, use 1 capful to a full sink of cold water. Put veggies in, swish around, then rinse with clean water. Viola, cheaper than vegetable wash from the store.
My steps, for right or wrong were:
- Empty RV Water holding tank, low as it could go
- Fill RV Water tank (with filtered water) most of the way
- Mix 2/3 of bottle (unsure how much, can't find bottle, though it's smallish) with pitcher of water
- Empty pitcher with mixture down fresh water fill tube
- Rinse more water down
- Continue filling tank till mostly full
- Drive down road (to next destination in my case), about 3-4 hours, only enough to swish things around is truly needed
- Prior to hooking to campground water, turn water pump on and run through water pipes to all faucet. Let the faucet/shower, hot and cold water, run couple minutes.
- Open up drain valves for hot/cold water by main water holding tank for couple minutes
- Let water sit in everything for couple more hours
- Leaving faucets open fill up grey tank with solution from fresh water tank
- With Toilet open fill up black tank with solution from fresh water tank
- Let sit for couple hours
- In meantime fill fresh water tank with, well, fresh water
- Empty Black tank
- Empty Grey tank
- Return to normal use
- Flush all lines with the fresh fresh water (still contains minimal amount of hydrogen peroxide,very diluted)
These are the steps I did from memory.
While flushing the toilet, did notice lots of little black things come out from the water pipe into the bowl so looks like this did the trick for most of it. With the faucets and shower, didn't have the white background so couldn't tell if anything got dislodged.
When can get more Hydrogen Peroxide will probably redo these steps just to verify all the baddies are gone, maybe even adding some lemon juice into the mix like the article above mentioned.
Other uses for Hydrogen Peroxide
While doing some research for posting this, came across bunch of other links regarding different uses for this. Here is one of the better ones, from Wolf Creek Ranch. Haven't tried anything specifically found there, just more interesting.
Drain Shutoff replacement
After doing this cleansing noticed some water dripping from the hot and cold fresh water drains by the main tank. These are used to drain the tank (like did above). It seemed like no matter what I chose to do, how hard I chose to shut them, they wouldn't stop leaking.
|First try, no clue..|
|Drop tube and faucet|
|First one on!|
Of primary note is the use of Teflon tape. Unsure if there are more environmentally friendly products to use to seal threads, but this is what have been using. Two key things to remember, if possible, as it makes life easier. First is to wrap the tape on fairly tight, tight enough so it "clings" to the threads. Second is try to wrap it in direction of the threads. This means that when putting on the shutoff valve, in my case, that the tape has less tendency to want to come off as am not trying to peel it back up.
