Title: Who has the worst water reading?
Post by: Steve Weatherley on June 18, 2007, 08:23:35 pm: My tap water reads 379 on the TDS meter. Can anyone beat this? Does anyone have exeptionally good water readings ?

Post by: Steve Weatherley on June 18, 2007, 08:36:07 pm: I thought those of you in the West country get very low readings (around 70 ish)?

How do you get the reading down to zero?
Just for the record here's what I do......

Water goes through a sediment filter (750 ml)
Then it goes through the Merlin
Then a 750ml D.I chamber (this I have to change every 600 litres!)
After water is pumped out of the tank it passes through 11 litre DI vessel

After this my reading usually comes out between zero and 2.

After changing the resin in the 750ml vessel the reading is usually zero or very low but after I have filled my 175litre tank about 3 times the reading goes up to about 15. This is why I have a 11 litre DI vessel inline between the tank and the microbore.
I was wondering if there was a problem with my RO membranes so have ordered new ones. I also plan to change the system to a static one as I have heard that the Merlin in a van bumping up and down can wear out the membranes quickly due to friction.

Post by: Steve Weatherley on June 18, 2007, 08:56:24 pm: I am pretty sure that my merlin only brings the reading down to about 50...
Title: Re: Who has the worst water reading?
Post by: Davew on June 18, 2007, 09:02:02 pm: I have Ro-man 300 gpd with no di and this gets my tds to five. Small di in my van takes it to zero, havn't changed the resin yet since Feb.
Title: Re: Who has the worst water reading?
Post by: vwm on June 18, 2007, 09:07:43 pm: my tap water is 248tds and the merlin brings it down to 11-16 any higher and i just change the filters. then i just di it in the van in a 11L vessel which is lasting me 6mths producing 400-500L a day.

membranes on the merlin should last about 3 years (static) dont like the idea of the ro unit in van

Post by: macmac on June 18, 2007, 11:46:34 pm: A customer of mine in a rural farm house has a natural water supply & the reading is 1500ppm on tds meter. yes 1500. un-known to me till this, as the meter only reads 3 digits it displays 150 then a little x10 flashes. Fortunatley for them, they now have a mains supply for drinking water which reads 92ppm.

Post by: Davew on June 19, 2007, 07:51:42 am: David, how do you know when to change your membranes rather than the filters?
Title: Re: Who has the worst water reading?
Post by: AuRavelling79 on June 19, 2007, 05:13:23 pm: My 200gpd membranes are nearly two years old and the water goes in at 385 and comes out at 13/16ppm (until recently it was between 9 and 12 so I think they are getting "tired".)

Then the water goes through the DI and it is 000ppm for about about 800 litres of usable water. It rises to 001 for the next 800L or so and then I get about 400L at 002ppm at which point I change the resin (750ml).

I don't have a resin bottle on the van and at the brush I get about 002/005.

Title: Re: Who has the worst water reading?
Post by: Count Phil on June 20, 2007, 02:42:37 pm: Ours is around 480 (mid bedfordshire)

Above 500 is illegal! The water companies have to keep it below this. If your reading is above this, report the water company.
