D.I.Y or buy second hand
Dont spend £1000s on what is essentially a pump, battery and a few other bits
I just pcked up this 2 man system off ebay last week for £400
Bargain! 700l tank, 2 pumps, 2 controllers, auto shut off, 4040 R.O, 2 D.I vessels and filters and it has a frame round the bottom to bolt in.
would i have paid the 3 grand retail price for it though ?
not a chance
Only thing i would change is the old tatty manual reels to some nicer leccy ones, ill probably D.I.Y them though..
