The pumped 600gpd day one? Any good?

Cheers

I would have thought you would be better off buying a 4040 or the more compact 4021 ro myself.

Cheap Chinese crap had the 300 gpd and it was a pile off crap

Cheers Pap, but I don't want to spend £700 on an Ro

Don't forget to add a pump Matty if your tap pressure is rubbish..

[Matt.]

Well that's were am stuck a bit, not sure where or wen I fill ever up it's different all the time, I do a tap tds test an one after I have ran the RO for a few mins and as long as it's in the teens al fill up.

So am not sure but is it hf4 for low pressure and hf5 for high ....... But I won't be using a pump

I do like the 4021 but the 4040 will fit along the front of me tank nice

Popcorn Dave 

Are you expecting a show on the other channel haha .......... I try not to get involved but that just tickled me silly

Just fit one of each, problem sorted surely?
Some yanks tend to use petrol driven booster pumps for on demand ro's which also is another option I suppose.

[slap bash]

I use one of these with John`s booster pump and never a days problem it looks like the 150 lit membranes which I would insist on as they are good.  A 4 membrane system with will have very little waste water as each membrane after the first one works on waste from the first membrane and the third one of the waste of the second membrane and so one. I can just hear the 4040 guys go mad as they do produce more product but do produce more wastewater as well.  Bigger is not always better.
