Water Meter problems

[Robotstar5]

Its that high here the waters laying on top of the ground

I was just thinking that, it's raining so hard here at the moment you wouldn't need a pump, an aquavac would be just as good

Today, this arrived from Amazon:

Now, I am not conducting some great experiment but what I would like to do is check m water doesn't have loads of contaminants in it. So far the tap water came out at 56 and bottled water at 72, this is just a comparison scale and I wouldn't imagine for one second it is measuring ppm with any sort of accuracy. The snag is 52 is the better end of the scale and 72 is heading towards the not so good end.

Would anyone care to comment?

It's a conductivity meter, TDS means total dissolved solids - solids of what? Then it gives a reading in Ppm - parts per million. It should read conductivity, in micro Siemens if I recall, but what does that tell you?
A bit pointless really.

i have about 600 gallons of water stored in the pit in my garage just pump it out if i need to use it or ok if theres a hosepipe ban

Do you wear waders to work on your car ?

no but i tripped up one day and fell in was sogged it probably saved me from broken bones if i fell the full 6 foot to the bottom

Have you thought of hiring it out ? Private pools are all the rage now

That's called a pond......

Technically I think it's probably the north sea coming home

Ah....a "Salt Pond".
Is it (to quote Jed Clampet) a Seement Pond ?

im actually considering one under the pathway of the garden at least its not heavy use there as its just a house pathway and it can also collect rainwater as well for the garden

Thats interesting, around here we have Spotless Water: https://www.spotlesswater.co.uk/

It is that cheap I use it for everything, windscreen fluid and especially, coolant in the machines. Washing the car and anything else I can think of.
I was really shocked when I checked the tap water with a TDS meter.

I'd be somewhat cautious of using heavily deionised water for anything that doesn't strictly need it. The lack of ions makes the water quite reactive around aluminium and yellow metals. Our deioniser at work produces water at ~0.5uS/cm^2, equivalent to ~0.3ppm and it will happily etch ally and makes brass fittings disappear. Only stainless and plastic fittings survive long term.

What sort of numbers are you getting on your meter?

That I did not know.

When using DI, you really do have to careful what fittings you use - it will de-zinc brass, destroy aluminium if its near stainless. Its so hungry for ions. It was an expensive lesson for where I worked 30 yrs ago. Needed a complete rethink for one machine design.

£6.59 gadget off Amazon - is not quite laboratory stuff...

I would agree and it is nothing more than an "indication" which is all I want really.

Now that I did know but completely forgotten until you reminded me. Blaser Swisslube in their instructions specifically state to use deionised water with their coolant so I do. There are no warnings about fittings and the only brass on the machines are the central lube system ones. As far as using it to wash windows and my car with, I think I am on pretty safe ground there. I hear you though.
