Is it a bad idea to store pure water in a storage tank in my truck bed for 3-7 days? I just ordered a WFP setup and want to bring pure water to the job site rather than filter on site for various reasons. I could filter on site if I run my tank dry. Was hoping if I don’t use all the pure water it can sit for a while until the next job?
Also what size tank do you guys recommend? I was going to get a 125 gallon, as I will mainly be using it for the 3 and 4 story hotels in this area.
Any recommendations on a 300ft WFP hose reel, as well as a reel for a supply hose?
Yes it is a bad idea, when you store di-ionised water in your tank, it has the ability to absorb the environment. If its high density plastic or a stainless tank. What it does to dirt on the windows, it reacts the same way in the tank. What you can do, and i have done is store water in your tank, and a 12v pump about 90psi and 5ltrs a min. And pump the water through the water filtration system and through the waterfed pole. I use about 3ltrs a min using a 400ltr tank. I normally only carry 200ltrs, that seems to do me.
The filtered water in you tank won’t clean anything in a day of sitting around. Sorry buddy.
A deep cell 12v battery and 12v pump, with JG water tight fittings is all you need.
Best of luck with it all.
Have you confirmed your theory with a TDS meter or other testing equipment?
In my experience, and from what I’ve researched, there’s nothing in high density polyethylene (HDPE, what most water tanks are made of) that can leach into the water, apart from possible manufacturing residue if it wasn’t cleaned effectively before use.
If you’re really concerned about the residue/leaching issue, only buy potable-grade tanks for your system.
I leave water in my tank all the time. I’ve never seen the TDS creep up over time, or experienced water spotting from an “old batch” of pure water.
Hmm, I don’t care how it tastes only that it has a zero TDS. I’ve stored di water in tanks for weeks with no problem. Being paranoid about bacteria, I tossed some alcohol in there too.
Your pure water water will be fine sitting in your tank. We used to store up to 500+ gallons in plastic water tanks for 2+ weeks with no issues or change in water tds.
an ex forum member used to post about stuff like this regularly.
here goes:
when water is freshly de ionized it is hungry and when put on glass immediately it is it’s most aggressive as a cleaner.
otherwise it will absorb co2 from the air which will satisfy SOME of its hunger making it a slightly less aggressive cleaner and lowering it’s ph BUT NOT increasing it’s tds.
windows still dry spot free if washed and rinsed correctly.
the water from purification systems used by window cleaners are not considered potable (drinkable) because our systems have nothing to kill bacteria.
MANY window cleaners store purified water without issuer.
i usually purify on demand but keep some 5 gallon barrels of pure on hand for use in my backpack sprayer, i use car wash soap containers ( lots of clean out required but free!) some were stored over winter and didn’t even break when they froze.
Back when I used to use the backpack a lot I used to keep gerry cans of made up pure water. One year I had a full backpack and 2 gerry cans of pure water sit over the winter months, brought out for the first job of the following spring season with 000 TDS water and perfect results.
I would think bleach might give you better bang for your buck. One or two drops per gallon should kill most bacteria. Whether or not that’s enough to cause spotting on the glass, I am unsure.
I think it depends on the type of tank and if it’s in the sun… not sure though. I filter my water after the tank. I know the water sitting in the 200ft of pole hose goes up to 5-6ppm and has to run until your back at 0ppm.
125 gallon tank is a good size but when it’s full and with all your equipment it’s going to be a heavy load.
