watermakers from Jetwashers
Being a Yorkshireman, inveterate tinkerer and all round tight git, I have decided to build my own watermaker. I have investigated this on the net its well documented, I find I can build a 40gph one for for about £1500 but........ I then heard about a dutch lad selling plans for using a jetwasher for the base but of course he wants his palm crossing in Guilders before he'll send you the plans.
My question is has anyone recently made a watermaker using a Karcher or similar and how did it perform.
I have a Karcher K7 that is surplus to requirements and needs a new hose has a performance spec about 3.75hp motor and 550l/hr (120 gph) at 2300psi so I think with a different (lower) pressure regulator at 1500psi the output could be increased probably to around 200 gph and a 12% conversion rate would give a watermaker of 24gph capacity
The mechanics of construction appear to be straightforward high pressure plumbing. There does appear to be a problem buying the RO pressure vessels in the UK as I've not yet found a supplier.
Input power isn't an issue, cost however is. Any advice will be gratefully received particularly on sourcing the RO bits in the uk.
