Advice on buying a RO-filter

[Matti]

Hi guys,
I just got my revenge osmosis filter and it works, kind of.
I spared couple of euros by buying the smaller dennerle and it's soooo slow.
So spend some extra and get a decent size.

The other thing I noticed is that it does not lower PH.
Otherwise it works fine, TDS is almost zero.

Couple of things:

• RO units require decent pressure input. They are typically rated for 8 bar input pressure @ 20'C. What is your water pressure ? You can get booster pumps that will dramatically improve the flow.
• pH is a ratio and as such a pH reading is irrelevant/inaccurate for RO water. Use TDS which is a better indicator of RO quality. Yours is TDS of zero so "sorted".

As Ian has said, you need a pump. I get 100l out of mine in about 6 hours connected to my shower cold outlet. Get the highest output device you can afford.
