Title: Pure water
Post by: brianbarber on January 05, 2010, 11:31:39 pm

hi guys,
If we use pure water (0.00 tds), to clean carpets, does anyone know what would be the ph value of tap water, as I believe pure water is the exact neutral ph value?
Reason I ask is I occasionally carry water to some jobs, but now have a 350 litre tank in van for my window cleaning.

Thanking you in advance

The PH level will vary from each persons tap and location.

You could get a simple PH level measuring kit online or simply pop into your local aquatics and they will have a PH kit but only a basic one. That will give you an idea.

I have often wondered if we cleaned with pure water 000tds if the carpets would actually be any cleaner visibly?

I have never tried.

I use pure water, dont think they are visibly cleaner but better in theory for equipment as no scaling issues however it has been raised that pure water is aggressive so long term could prove detrimental to seals etc but have not found this yet.Pumps tend to be so unrealiable and have short lives its hard to tell if its running hard water through them thats bad!

I think when chemicals are formulated the chemist uses pure water so in theory shoud give better results but prob not that you would visibly notice.

I wonder that if pure water leaves the carpets feeling any softer underfoot in hard water areas.

Not sure of the ph values at cold but I'm assured that heated pure water has an acidic value.
Pure water is softer because all the calcium is removed by the filter membranes. Si theory if you use heater pure water then you will be giving the carpet an acid rinse and it will leave softer carpet too.

Im no chemist but as far as I know your water will still be "hard" after the R/O process if you live in an hard area unless its gone threw a softener before R/O.

Ph is not affected by going threw R/O

Hot pure water is not more acidic than cold

Pure water doesnt clean carpets any better than normal water and is not more aggresive (thats just sales talk!)

perhaps we need our very own chemist to answer in more detail and to clear this subject up ;)
