For the moment I'm unsure if I will then schedule a weekly visit to the boat to flush (15 minutes drive & walk, door to dock) or if I will pickle it again.
Assuming I decide to skip the weekly commitment and pickle after a couple of weeks, you are recommending I should change the pre filter (only one) again.
You will have a Desalator desalination unit on board then Hoppy (probably a Duo 60). The procedure is very quick and easy.
Remove the pre-filter element (bin)
Pour the sachet of preservative powder in the cartridge supplied as part of the OEM kit
Put the cartridge where the prefilter element was
Open the back-flush valve (also back-off the regulator
valve on the control panel
so it can actually back-flush with your on-board pressure system)
Let run until nearly all of the powder has dissolved (less than a minute), then close off.
That's it. Come re-commissioning time, continue the backflushing for several minutes, to work out the preservative, then replace the pickling cartridge with a new pre-filter element, and you are ready to run (you will still want to run for several hours before letting the product water into your tanks).
Tip - the preservative powder supplied as part of the OEM kit is sodium metabisulphite. You can get a 1kg bag of it from some home brew supplies shops in Australia
, then weigh up single
dose lots, and for about $4, you will have enough for the next 6 years of so.
Note also, that if you have chlorinated water in your tanks
, this can cause damage to your membrane (Telly will be able to advise further on that - some membranes are more sensitive to chlorine than others), and as the Desalator Duo 60 does not have a carbon filter, you need to be aware of that
Hope that helps, and hope the shipping
back here works out well - would be interested to hear the charges if you want to PM me.
