Yeah there's 3 new filters underneath it.
It's ordinary hose. Didn't cost much and yes it takes half hour to fill, but doesn't matter. I just turn it on and carry on with whatever I'm doing.

What ro unit do you have? I have a tds in the high 400s. My 300gpd ro will bring it doen to 27 on tap pressure. It says approx 50psi on my ro.
i was automatically going to say get a booster pump, but you sound ok for water pressure. With a higher pressure the tds should be lower than that. 2 di vessels saves loads on resin.
Also, i think it's better to not fill the vessels to the top, cos a good shake will extend the life of it. With 2 vessels, they should be good for awhile.
But bringing it down from 29, it sounds about right.
Give the vessel a shake and that should come down further.

Unfortunately this is normal rog. A bigger DI chamber or 2 chambers is a good idea.

Alright, thanks.
Bit disappointed though. Everyone said I wouldn't have to change anything for months. Not a week and spending out already.

increase your pressure and check your membranes. you should be getting a better reading. what size flow restricter do you have on your waste?

I don't even know what that is, sorry!

An RO man system is usually pretty much plug and play, I doubt he needs to take his membranes apart, he has most probably put it all together correctly and turns on the tap to produce water.

As we all know there is a fair bit more to it than that.

Roger, I hope you are not just sticking the hose for the RO straight onto your kitchen sink tap?
Fingers crossed you have followed one of the bits of advice you were given and fitted an outside tap under your sink and drilled though the wall so you could at least have everything permanently connected.

Absolutely EVERY TIME you use the RO you should flush for a good 10 or 15 minutes before letting the membranes get down to business, and pop off the tube leading from the RO membranes into the DI vessel as it can take several minutes before the RO is working to maximum efficiency.

The RO man systems usually have a one litre DI vessel, the same dimensions as the two pre-filters, as you know, I coped fine with the same system for a few years and only ever had one DI vessel, once the resin starts to become exhausted, you can wring a little more use out of it by passing it through a second vessel, but if the first one is totally spent it can have the REVERSE effect  and the water coming out of it can have a higher TDS coming out than going in!!!

Most DI vessels are much larger than the one you are using though Roger.  If you were using a much bigger one, the resin would have lasted much longer.  If you buy a 25kg bag of resin, it ought to last you about 3 months - a bit longer if you run the resin through two vessels.  The second vessel could even be in your van at a push if there is insufficient room at home.

the problem is not with di. its with the ro. at 290 from the tap it should be coming out less than 29, less than 10. so its either not getting enough pressure or the membranes aren't seated correctly.

[geefree]

it sounds like a 200 gpd ro man,

my water at the tap is now 270.... i have the same ro man , only its 300 gpd,

and it brings my tds down to 00.02

without a 10" resin vessel.

I think you should increase the pressure at the tap squeaky, and get some better connectors so they dont blow off.
