that Vyair will give you around 50l per hour, with a 2-1 waste to good output.

its a good RO for the money

thanks gto, dont think its going to be quick enough for my needs though,

might be an idea to also check that the inline tds meter is actually registering correctly by using a hand held tds meter. I heard once that the inline units aren't very accurate.

Also the units Gap supplies with 10" housing appear to have 2 pressure gauges now. If yours has 2, the first on the inlet and the second after the chlorine filter, do both gauges read the same?
C-N-C would have appeared to have bought his at the same time as you, so I expect that they would be the same. If only 1 gauge then is that registering the correct water pressure to begin with?

What's your pure to waste ratio? Just guessing is the worst thing to do. You need 70/30 or so. Restrict flow with a ball valve. Forget about measuring pressure with the waste open. Check your pressure when your valve is set at the right ratio. I get next to nothing pressure when flushing. That's the way it is.

morning ian
spruce has just given me the idea that I could atleast test it by putting in the kitchen (not permanently too small a space) and could flush it this way with greater pressure which may prolong its life and bring down the tds a bit.

not sure what you mean when you say you've run yours 40 ft away ?
where was the pump ? at the water source or at the ro ? and on the same level I presume ?
reason being I tried a clarkes pump and it made no difference when connected before the pre filters and ro on the first floor. Manufacturers guidlines were for the pump to be at same level and as close to water source as possible which is why it never worked for me.

what clarke pump was it, do you have a link ?

If I remember right it was this one I tried but returned it

you do not need 70/30 waste to pure at all that just slows things down a lot, 50/50 is perfectly fine I have been doing it this way for years with the same 4040 no problems at all, I flush on everyfill
