does anyone have a diagram of a twin 4040 setup.
Also what do you do with waste to you recycle some of it.

thats the kiddi, I just need a close up to see how it is all plumbed in ect, any chance ?

Or anyone else got a diagram of one 

[Lee Pryor]

its very simple, it started off as a single and when i added the second RO i just cut the hoses and added some Y piece spliters then plumbed it in the same way as the first, we did recycle some of the water, but with the pressure boosted to a constant 80-100psi it hardly wastes anything so we dont bother anymore

what waste to pure do you have ? and what is your input tds and output.

Many thanks for the info by the way.

Ian thought i would knock this up for you mate

Tds from tap is about 250ppm, then after RO (pressure makes a big difference) 4-7ppm then ooo after DI waste is very little maybe 10% i mean its just a small trickle, booster pump is a must!

You will need to zoom in on this to read mate

Cheers for that Lee

Daft question but do you get double the waste?

[Andrew McCann]

I hate to jump in and pour cold water on the very small waste percentage of 10%

Even with a twin set up using a booster pump 10% is just too small a waste to product ratio. Your tap TDS is a lot higher than Lee's Ian and even softened as I believe your ingoing water is you are very likely to kill your membranes without at the very least 30/40% waste. One other big effect of low waste is increased TDS out. Lee.. if you increase your waste I would almost guarantee output TDS will drop.. maybe even to zero.

OOPS grub is ready...  I will come back to this re recirculating waste a bit later.

You havnt replied to any of my emails.

Do you want to buy the ladders?

Bob?
