I'm planning to assemble a tankless RO purifier for home use. I found the following sites selling RO spares

hitechro
pearlwater.in
jeitechaqua.in
satyaneer.com

Are they reliable, have any of you ordered from them?

Also Konvio Neer parts seem very popular on Amazon. Any experiences with them?
 
Piggybacking on this thread, when is it the right time to change the RO filters? I have not changed mine in almost 1.5 years and I checked the TDS the other day and it was 22, whereas the raw water was 350. Does it make sense to change the filters right now? Or should I just change the prefilter? If not, what is a good time-range and metric?

Usually our service guy checks up and changes it when its time..

Yeah, ours was under AMC too and he'd regularly come and change the filters. First he started off with the Aquaguard filters and then shifted to the local ones. I was just wondering if there is any metric to find out when the filters actually need to be changed? Service chaps would say they need to be changed on the regular, since it means more money for them.

Ah I see, thankfully my service guy doesn't loot us :p he is quite reasonable..
 
@sibot I used to change the ro membrane when the water took too long to refill. If water is not hard, then ro membrane lasts a long time. Also depends on the brand.

I would change the sediment and carbon filter regularly since they may have limited absorption capacity (I used to just flush the sediment snd carbon filter). Maybe change them yearly or earlier since they are cheap.
