Aquaguard filter candle price and change frequency

What is the general market selling price of aquaguard filter candle and how often should I get it changed? Is the changing frequency same for carbon and UF filters.

Also the installation guy was saying I should get some device installed to increase water pressure. Costs around 800. Is it needed?
 
Parts are available on Ebay at vary cheap rates than offline price. I change spun filter frequently and other according to need when filter starts to chock.
 
If you are getting it done from a agency - call Aquaguard directly and get it done. The last time I got it done through a third party, got cheated.

Its easy to DIY, but ensure that you do it right.
 
Frequency of change would depend on the input water quality. If it is clear enough, the AMC asks for yearly change for the carbon granule filter.

Most probably, he is referring to a "Flow Restrictor" which costs less than Rs.200 in ebay.in.

RO membrane comes with capacity mentioned in GPD. A common 80 GPD RO membrane ( outputs water @ 80 gallons per day ) translates to 302.84 litres per 24 hours which equates to 12.62 litres per hour. For a RO equipment ( with 80 GPD membrane ) with 10 litres storage, it should take around 48 minutes to get topped-up from empty. Whatever water ( with dissolved solids ) that does not pass through the membrane ( rejected ) comes out as wastage. This wastage of water will differ between brands/models. I am using a 10 litre Zero-B pristine which rejects around 22-24 litres of water for every 10 litres of purified water.
Theoretically speaking, say I squeeze the the wastage outlet pipe ( with hand ), thereby restricting the waste water from getting out, then the water that cannot come-out will be forced to pass through the RO Membrane. This is what a "Flow Restrictor" does. While a Flow Restrictor is useful when top-up time/water rejection is high, it would/could also lessen the life of RO Membrane.

An injured RO membrane will allow dissolved solids to pass through it. I highly recommend a TDS meter ( around Rs.600 in ebay.in ) for all RO users.
