In general Germany's water comes from lakes and deep underground wells. Over 20 years ago they introduced laws to stop people washing cars with soap unless there was a water catchment system to stop detergents filtering down into the water table. A pain for car drivers as you can't wash you car at home with anything other than tap water.

Don't drink the expensive wine though, they made that in lead vats and the acidic content of the posh wines dissolved the lead and driving them all mad.

Re: Watermaker Myths

I've been volunteering myself, my own time, picking up marina trash for over three years. Mainly outside the marina via dinghy.
#1 item I scoop up - plastic water bottles.

Our society has been brainwashed by big bucks (coca cola types). We have become far too lazy (for some I get why they do it) to refill a lightweight canteen to take to, wherever.

I wish I could afford a watermaker! I am that gal who schleps refilled jugs of water back and forth. I wouldn't drink from most of the marina water I've experienced (with a Brita no, maybe with a high end filter) it isn't the city water, its the old, poorly maintained plumbing. Brownish tinted with specs is not okay. Marina before this one had salt water leaks.

Re: Watermaker Myths

When I deliver a boat with a watermaker, I drink the tank water. As I had a bout of reflex fainting yaesr ago,I add Gatorade crystals to boost my electrolytes. I have a nifty Thermos water bottle that has a built-in straw so I do not have to tip the bottle. On a monohull tipping the bottle is an invitation to wear the contents of the bottle.

When teaching on the West Coast I drink tank water also laced with Gatorade.(there are some places I will not refill the tanks.)

My only complaint about RO water is that is pretty flat tasting. So I also carry ice tea mix.

Bingo...
Getting people to pay a price for water that is more than diesel per gallon is marketing magic. We hear all the hate directed at Big Oil...when it is Big Water and their never ending plastic bottles that should get the real stink eye!

Yep, always enjoyed watching people complain about big oil as that plastic bottle of fancy tap water was right next to them.

Re: Watermaker Myths

Referencing the WHO article, we can do a little math. The article recommends the following water content for magnesium and calcium:

* For magnesium, a minimum of 10 mg/l (Novikov et al. 1983; Rubenowitz et al. 2000) and an optimum of about 20-30 mg/l (Durlach et al. 1989; Kozisek 1992);

* For calcium, a minimum of 20 mg/l (Novikov et al. 1983) and an optimum of about 50 (40-80) mg/l (Rakhmanin et al. 1990; Kozisek 1992);

Assuming you drink 1-2 liters of water per day, they are recommending you get about 50mg/day of magnesium and 100mg/day of calcium from your drinking water. This represents about 10% of RDA. Ice cream is high in calcium. Chocolate is high in magnesium. So go ahead and drink your RO water but don't forget the sundae.

Wish the high cost was a myth. Do the Chinese make one yet?

When compared to the cost of the boat and ongoing maintenance cost, the water maker is chump change, especially when convenience is factored in.

Don't count on the Chinese offering the fantastic customer service and high quality merchandise the folks on this forum offer.

If they put melamine in dog food as a filler which caused many pet deaths, I sure as heck wouldn't trust the water coming out of their product.

The new systems are pretty much automatic and have much higher outputs.

The one on the Leopard 44 I delivered in September/October is essentially foolproof.

I don't think a good watermaker will ever be inexpensive. I recently put one together from information gleaned from the internet. Predictably, the highest proportion of cost was the high pressure pump at just under a boat buck. Surprisingly, the next highest proportion of cost were the many s/s high pressure plumbing fittings. I don't see any reason for either of these things to come down in price. Shopping relentlessly and doing all the work myself over a period of months I spent somewhere between $3,500 and $3,800. Sure, you can do it cheaper, using inferior components, but if you do the unit will be failure-prone and you will find yourself waiting for parts in mananaland, hoping for rain.
