First of all I really appreciate the sales mania of ef(eureka forbes ) salesmen company trained them perfectly to sale its product even if person does'nt feel any use of company product.
Guess what to sale RO to my father ef sale executive was just hovering near my house even my father says "no" to buy it clearly he.comes 3 to 4 times even after returning him after closing door...
but at last he convince my father to purchase it. Well comes to point about RO
weight= slight heavy
color =white
looks =simple
material=durable
output =8 lt per hour
waste water every hour= 30 lt appx
tds reduction upto 95%
collection unit= no
automatic function =no
well it has five filters
which mrp combine 5 cost around 3100
yet all five u can get at discount in near 2300 rs apx from any ef franchise
well as we try its filter and membrane run for near 9 month
tds 600apx output tds near 30-50 apx
well it gave almost mx 9000 lit water
as I research its filtered water taste some bitter as we are adjusted to high tds water that conatin high iron contains that cause water to be sweat in taste at high tds
water look crystal clean after filter from RO
well look for maintainance
as this ro have all push fit fitting its filter replacement does'nt need more labour
just open 4 outer and 6 inner screw and it is open
just click and push connecters through which filters were connected with white pipes to eath other take new one and again push coonecter to filter end and thats all
well this ro membrane that s the imp thing I research as indicated 75 gpd (more gpd means more filter output capasity termd as gallon per day but when I cut old mem from this RO ef supplies
100 gpd taiwan made csm membrane (100 gpd does"nt means it is definately better than 75 gpd one because ooutput also depend on brand and quality as chinese one 100 gpd membrane gaves same performance like 75 gpd standard one )
CSM is cheap oem membrane supplier to various RO manufacturer but not good brand in world of RO membrane
so you can put itself separate brand cartidege that comes even cheap than ef oem membrane that cost min 1800 RS(MRP 2350) and csm cartidge u got in that ef 1800RS cartidge
so to cut membrane u could get vontron or filmtec (filmtec dow chemicals is best brand and no. 1 quality brand in whole world ) in around 800 and 1200 rs and casing 200 rs and put in THIS RO whenever membrane got out
this compatible cartidege u could easily clean after removing from housing.
but u eureka forbes supplied CSM membrane u cant clean
so u at least need to spend on every 10 k litre on filters and membrane change apx
1200+600( 600 original ef carbon filters u could get local one also cheap but as there is no much difference in original ef and market one u can use eureka forbes ones)
than total spending will at least 1800 RS
u may need 20RS push connecters that is 5 to 6 rs /unit cost as connecters were worn out and leaked after months of usage
so overall this is simple design RO that u can maintain itself if u gain some knowledge
second thing ef provides 1 year amc for rs 3000 in which 1 time all filter and membrane replacement
given and any electric part replacement throughout the year whcih include mainly electric pump replacement without labour and cost
ok after apx 3 years on near 9/11/11 its pump head failed so I install 800 rs local booster pump and at this time I also replace orginal oem ro membrane cost 2000 with chinese vontron ulp-1812-75gpd cost about 700 rs and than I checkout tds by two person meters to ensure the tds reading
input water(tap water) tds=650 apx
output water (ro water) tds =35-40 apx as two separate reading by two meter
