Then perhaps you can answer this question.

If one were to install a TDS probe in the RO's waste pipe, would a comparison of the feed pipe's reading make it possible to determine when the flushing procedure was completed.

i got my ro system from pure freedom, had it 3 years never flushed once and it is excellnt !

[easy clean]

No, waste of time just flush it as often as you can

I don't believe thats possible. I don't know it for a fact though. A RO's whole process ensures it is flushing whilst being run. The 'additional flush' is just to ensure there is no contaminants on the membrane. There is nothing concrete to say there is anything on the membrane in the first place.

[Nick_Thompson]

Mr CleanClear, that is a very good point. As you say, the whole possess of reverse osmosis, as it occurs inside these housings, lends itself to a continuous flushing procedure.

Perhaps, then, it is merely a question of water pressure and flow rate that determines whether mineral deposition would ever proliferate the outside wall membrane.

Michael, it would be very interesting if you, or anyone else who has forgone the flushing recommendation, could take a peek inside the housing to see, if indeed, a clean membrane laughs in the face of the flush.

[R.C Property]

if the RO has been sitting for a day or 2 not being used then the tds reading is higher when first turn on due to the settling of the impurities in the RO. always good to flush each time before you start to make pure water.

I took the membrane out of the housing about three weeks ago just to rinse the housing out , which i did using the transfer pump to flush it out with pure water, also cleaned the housing out. Just a small amount of surface slime. You can't really see inside the membrane as its covered with some sort of strong white tape. But usually just do a short flush occasionally, 15 mins or something about once a fortnight or whatever. But certainley no regime to do it regular.

I have a merlin but there is no flush on it. If I plugged the pure outlet would that be what flushing does.

I wouldn't recomend doing that. There is a flushing kit available for a Merlin. How usefull it is for our purposes i've o idea as it works by coming on for a short time after each 'production'. I think this is designed for home use at a tap or such like.

ionics used to recommend to backwash every 1000 litres which is pretty expensive coz it costs £2 per bag of salt and to ro flush once a week

i try to backwash 1-2 a week and flush once or twice a week at same time, with out the ro ur knackered really not pure water no work look after your main tools guys

What is 'backwash', can you describe what you do?

[richywilts]

on the ionic systems you have a cylinder type canister that you fill with dishwasher salt and change hoses about and it backwashes the first two filters (basically your pre filters before ro) to regenerate the water softeners or something

ok cheers.

it regenerates the softener resin
