Re: [Amel Yacht Owners] Pickling watermaker

We also do not pickle our water maker, having been dissatisfied with both SMBSulphite and propylene glycol. We flush with own freshwater for 45-60 sec (about 8 liters) after every use. For extended periods without use, we flush with 200 liters after removing the pre filters. We have left the system for 6  months over the summer in the Sea of Cortez with no problems on return. It does take about 20 minutes to give satisfactory water after the extended inactivity. We’ve done this for 7 years now on these membranes (we have 2 40” ones).

Tm with you on this Eric,
I approached the Watermaker with fear and trembling. How to care for it, how to clean it how to pickle it. When to pickle it. How long could you leave it before you should pickle it. 
I am grateful to the advice from this group which lead me to the fresh water back flush. Now I just back flush with fresh water after every use. There are times I leave it untouched for two months or more when I am away from the boat. I just start it up, run to waste for a few minutes and all good. The membranes are still good. 120 ppm. The pre filter does need changing periodically but that would apply anyway.
It is some years since we put any outside water into our tanks. Got to avoid introducing chlorine. Another good bit of advice from this group.

When I leave the boat at a marina and am away for a month or more I pay the dockmaster to run my watermaker. I added a switch to the fresh water pump in the engine room , so that the only time the pressure water is on is when they run the watermaker.
Works for me but each case is unique. I just lost faith in sodium- whatever as it destroyed all the fittings and bobbin on my watermaker.

Hi Eric,
That's fine if you are near the boat, or can guarantee that you always have enough fresh water and do what Bill on Bebe did with a solenoid valve and a timer to flush the system regularly, but my point was the distinction between SMBsulphate and sulphite which are completely different chemicals.
I prefer to follow what the membrane manufacturer says, rather than what somebody "believes" to be true.
But each to his own....whatever works for you can be fine for you...but maybe not for me...
