Hi Everyone.
Having a problem with my water purification system which is as follows:
Typical 3 stage pre filter (5 micron, carbon block, carbon GAC)
Typical 3 stage RO system which produces 300 litre per day
20" resin filter using high quality Tulision resin
This feeds a 1000litre storage tank
Tape water varies between 175 and 275ppm
I wouldn't say my system is used heavily, maybe about 1000 litres per week.
I back flush my system regularly (monthly)
I been using the pure water system for about 5 years
I change the pre filters approx. every 6 months.
Last summer I changed my RO units for the first time.
Change my resin as and when ppm raises above 12-15ppm
Problem:
My water quality has has dropped off a cliff measuring about 50ppm. (4 days ago) So I immediately changed my resin which worked, bringing the reading back to zero. But within 36 hours to was right back up. I have just (today) changed all three pre filters and re-connected the system but without the resin filter. It measures 55ppm (tape water 200ppm). Which seems high, so I have also measured the water quality before the RO section - so just the pre filters - and that measures 200ppm, same as the raw tape water. Indicating to me that the pre-filters are not doing anything.
So my overall question is - Where does my problem lie?
Approx. what amount of impurities should the pre filters alone remove?
Approx. What amount should the RO units remove?
Approx. What amount should be left for the resin to remove?
I'm at a loss as to which part or parts of the system are failing and why...
Thanks to all who read this, hope it's understandable and thanks in advance for any help.
Regards
Carlton
