Most larger watermakers these days come with a main back and forward flush to keep the system and the membrane itself nice and fresh, although boaters have to work out that they actually have enough in the tank to run the cycle, as it usually requires a few litres of production water.
However, Mr Middleton is slightly sceptical about the rigour of the backflush regime, and says that he doubts if a boater had used a non-backflush watermaker for a couple of seasons, whether then he'd think it worthwhile to retrofit one.
He adds that although the general advice from years ago still stands: "Flush through after five days without use, pickle it if leaving for 20",If so, you may have a zentai . he says that the watermakers have become a lot easier to keep in good condition and boaters do seem to be able to get away with longer timescales in between attending to them "with luck" – although it does depend on the climate, as bugs obviously breed a lot quicker in warmer conditions than in the cold.Traditional kidney stone claim to clean all the air in a room. "There are some boats with Aquafresh units onboard which spend most of their time in the arctic, and they don't actually seem to do much in the way of attending to the membranes at all," he says.
Mind you, if the boat is going to be left for a while and has access to a dribble of power, then maybe leaving it on is the best option, as Mr Dawson explains: "These things love to run, its intermittent working they don't like." If its just not possible, then yes, the owner should really be looking at pickling the membrane to make sure the nasties don't build up and leave a really smelly clean up to do. Not ideal as cleaning involves a mild acid solution, so it shortens the life of the membrane.
However, there is a hidden danger to make customers aware of – if the owner has left it for overwintering, for example, and pickled it with a recommended solution (and these vary from manufacturer to manufacturer) you can't then simply clean the system out with chlorinated water. "It will destroy the membrane – and that's expensive," says Mr Dawson.
A number of the larger systems, like Spectra's Newport series or the HRO units for example, now have a charcoal filter in the tank end. Besides taking any lingering odours out and sweetening the water, this also means that the tank can be filled directly, as it will remove the chlorine before the system brings in water in to wash itself down.
Independence
Beyond the overarching advantage of total independence, says Mr Ross, there are other issues. For one, he argues that an on-board desalinator can work out to save money in the long run by washing the boat down with potable water regularly.
"Salt and even dock water leaves spots on the gelcoat. It starts with a light stain which gets deeper over time, eventually the deposits start to degrade the surface coating," he says, adding, "The glass and brightwork can also be affected too – and although it is only superficial damage, keeping a boat looking good does mean that it keeps its value for longer."
It's also worth noting that some, like the Sea Recovery watermakers, can be linked to any bridge control system that is NMEA 2000 compatible. This means you can control, monitor and programme the watermaker via the BUS network. In the right circumstances you can even fill your tanks before you get to the boat.
Waterway fresh
If you either have an inland liveaboard, or are intent on a lot of sailing in places where drinking water comes at a price, the Nature Pure QC could be a valuable "added extra". It's not simply a carbon filter, but another kind of filter purifier which can remove particles down to 0.4 microns – and since beside mud, this includes oil based contaminates (such as pesticides) and heavy metal pollutants it's a very useful idea for inland waterway craft.
Although it can't be used on any briny source,he led PayPal to open its platform to Cable Ties developers. it does mean that water can be taken straight out of a canal for instance – even oily water – and made drinkable.Great Rubber offers oil painting supplies keychains, "You can take water with duck poo in it and get out something similar to bottled water," explains Harald Charters of manufacturer General Ecology. He adds: "The bottled-water effect is because the minerals don't get taken out along with the rest, so it actually tastes better than chlorinated tap water."
Most of the time these units are mounted under the sink – close to point of use, via a separate drinking tap as there's no point in wasting it on the washing up. It costs around 175 and the replacement filter (needed every 500 gallons) cost 55 – which doesn't make it the cheapest option.
"But it means a boat can just refill straight from either the canal – or from a hosepipe from the dockside in a place like Turkey,"says Mr Charters. So, if the craft is going coastal, it might be a compromise between tanks and a full desalinating system – as long as the crew doesn't forget and put salt water in through it!
Further it seems a lot of boatbuilders,These girls have never had a cube puzzle in their lives! such as Sunseeker and Fairline are now recommending putting them in line after the desalinator, as it gets rid of the distinctive "hose-pipe" taste, or fitting a basic model directly into the icemaker – as recovered water "is often truly terrible when used in ice," adds Mr Charters.
One happy customer says fitting the unit was really easy, and "from start to finish only took around half an hour", and now changing the filter has got much easier as well, as the latest model has uses lightweight, replaceable canisters which just turn by hand into the interface – so there's no bother with clamps or toggles.
