Re: Rverse Osmosis

I used a Merlin RO unit some 5 years ago when I had a play with RO and was not that impressed. I had good water pressure of ~ 50 psi and the waste water was ~ 70% and good only 30%. This was the main reason for me giving up on the RO thing as I was on a meter with a large pond. I think there are bet...

Hi All IMO. 2 drains on the market that are worth considering, ****** and the Spin Drifter. Similar/same price. Similar/same construction method. Spin Drifter max air delivery reccommended is 40ltr but some have got away with 80ltr (but for how long). ****** one will take up to 400ltr no problem. **...

The Kohaku is way out in front for me.
