Another Tool/Gadget to finger my D.I.Y. Itch,

Will be Using it to monitor RO Water and would skip the service contracts, cause spares are easily available now a days
and for those who know how it works, can easily save a couple of thousand a year.
Basic operation is, You can check TDS level twice a month, The least the reading is, purer the water is.
my current reading is 21 after 1 year of usage. I am not spending 4.5k on contract this time.
New Filters and membrane installed would give readings, near 0(Zero) while normal home usage of 1 yr. should not be more
than 15-25. and if you change the sediment filter in 6 months, your membrane would last twice its normal life of 1 yr as suggested by companies, but all that counts is the TDS Count, So watch and act.
new filter set would be around Rs.900 ( 3 filters)
One Decent Filter membrane would be Rs.1200-1400
and companies charge 4K + for annual AMC so what they would cover extra is PUMP, and that's only Rs.1000 tops, so all in all even in worst case scenario (Blown Pump) you can save Rs.1000 and if pump doesn't needs to be replaced you save Rs.2000+ a year.
other parts are considered as consumables and would be charged by AMC providers so its out of equation for D.I.Y. cost.

Last pic from phone cam before it went down for 2 days :-)
Bought Pocket Digital TDS Meter from this seller delivered a day earlier than ebay estimated time.
Paid Rs.550/- after ebay discount coupon.
 
Yes, thats why I am never going to switch to water purifier! :)
 
I'm now thinking of buying this kit:

RO Complete Service KIT With 80 GPD CSM Membrane FOR Water Filters Purifiers | eBay

Just not sure if my ZeroB Prestine can accept all these filters. Need to open the filter this weekend and figure out.

Zero B used to charge be 7.5k for biannual AMC, it was a complete rip off. They gave me the candles & kit only once in 2 years, and the last change happened 2 yrs back. They never come and change the pre-filter which should be changed every 3 months. They only respond oncall.
 
truth is its a great ripoff game for all companies .

i think you should have get membrane changed along with filters on your own will..............or did they not allow it?
 
Last time they visited, almost 2 yrs back, they changed only the filters and said the membrane is still good to continue. So I'm still retaining one sealed membrane from them. Their present 2 yr AMC expires coming Jan. Once I get the TDS meter, if i find the TDS level high I'll ask them to come and do the needful, it will be a learning experience for me too. :)
 
I do all the RO maintenance myself. Buy the spares from ebay. Easy to get spares if you have Kent RO.
Big cost saving and Peace of mind.
