Hose - in-line filter - water tanks

[Piers]

Jusy seen a boat fill their water tanks using an in-line filter which they fitted between the pontoon hose and their boat's water tanks. Seems a great idea to me, but what to use? Any ideas?

useless gimmick ??

Really? Wouldn't it keep the dust and whatever from reaching the tank rather than the sediment sitting in the tank?

from a mains water supply ?? think its called paranoia

I have a 10 micron water filter after the water tanks, and it needs changing every 4 months. Black and restricting water flow. Maybe Guernsey is different?

Mechanical filters are only good for catching sand or other "hard" impurities, which depending on the marina might be a problem or not.
A water softener is imho much more useful than a filter alone, because on top of filtering impurities it also removes calcium from the water, hence keeping cleaner the whole fresh water circuit and making showers, hand washing etc. much nicer.
This is the model I fitted onboard. It's directly feeded by the direct dock fresh water connection, and can obviously be used also for refilling the tank.
Short of a full flagged reversal osmosis watermaker, it gives you the best fresh water you can get. Highly recommended!

PS: I can understand anyone suggesting to not bother using anything at all.
It's one of those things that you can't appreciate till you try it. :encouragement:

I would disagree slightly Mapis as using the correct inline filter to the tanks can remove a lot of impurities and additives to mains water and the most common types of impurities are aluminium additives which do actually have a health risk for many people. Using a simple activated charcoal based medium will remove most of these before they get into the water tanks along with any other silts or solids, and water quality varies around the world, something to remember.

Water softeners, yes, totally agree so why not use both and filter your water going into your tanks and put cleaner water into your softener.

Hi Piers

I would believe he had a side flow filter. For the filter you should have a combination filter, 5 micron + activated carbon, it is possible to fill qualitatively good water. You can find such a local HVCA store or web shop...

Example filter house, hight 10". Fiting 3/4" or 1".
https://www.lvi-kauppa.fi/epages/Lvi-kauppa.sf/fi_FI/?ObjectPath=/Shops/2015031303/Products/3614810

Example filter flow 1500 litres / hours max 8 bar.
https://www.lvi-kauppa.fi/epages/Lvi-kauppa.sf/fi_FI/?ObjectPath=/Shops/2015031303/Products/3614814

About this filter: Household and industry Polypropylene filters out water from sand, algae, etc. debris from activated carbon to enhance water color, taste and smell

Or beter filter
https://www.lvi-kauppa.fi/epages/Lv...g=Mikro-+organismisuodatin+0,15µ+Atlas+SX+10"

About this filter: The filter is designed to eliminate bad odors caused by small microorganisms and organic substances, and pesticide residues, insecticides and chlorine detergent residues. Also removes water from the water. salmonella and legionella bacteria.

And last examples pro version double filter system

You can build an easy rack for the filter house to attach to your railing or other place and once you've refueled you move lazaret etc.

Actually, we are not disagreeing at all.
If you click the "Tech Specs" in the webpage I previously linked, you will see that it includes a 5 micron carbon filtration cartridge.
In hindsight, you might have read my sentence "on top of filtering impurities it also removes calcium from the water" as if I meant that the ION exchange resins alone are also good for filtering the impurities, but that's not what I meant.
The water flows through the filter first, and then through the resins - all "in the box", so to speak.
It is indeed a smart little package, though obviously a bit larger than a filter alone.
Btw, don't be fooled by the dedicated website: it's actually produced by this company, specialized in top quality watermakers, up to 1600 L/h, with either single or 3ph power.

I knew we had been here before lol. That's quite a neat setup and a fraction of the price of the Spot Zero setup Magnum (RIP) had specced for his new boat. http://www.ybw.com/forums/showthread.php?488839-Fresh-water-filtering-and-softening-suggestions

MapisM - how many litres before regeneration? Is regen manual?

 

[MapisM]

4k litres, and yes, regen is manual (the equipment only works by water pressure: no electric pumps/valves of any kind - a simplicity which I like, on a boat), but very straightforward.
It's just a matter of positioning a couple of valves in order to backwash the system first (10 mins), and then rinse the resin with the salt (30 to 40 mins - the process is completed once all the salt is used).

Btw, the box can be left on the dock and used pretty much as any in-line filter.
I preferred to have it installed in the boat because I already had a straight dock connection, and it was easy to fit it in-line with that.
Besides, I also had a decent space in the lazarette astern, where it's well protected by sun and rain.
The only small complication if you should go for that type of installation is that you need an outlet for discharging water upon regeneration, but I was lucky in this respect because I could use a small shower box+automatic pump nearby, that was already there for the a/c chiller condensation.

Mapis, moot point as there are many ways of doing the same task, OP didn't specify what type of inline filtration system they were using.

95% agreement generally but without OP knowing what the inline filter was it leaves it open to interpretation and assumption, but hey that's life as Esther used to say.

 

[Piers]

the boat was on a delivery trip. Malaga to Hamble with a stop in Gibralter. Had to pull into Guernsey to take oin water - someone had lefta tap open and dumped some 2,500 ltrs of fresh water so the last 3 days were withoiut any water. And the water maker had broken.

Watching them fill, there were two filters.

The first appeared to be: https://www.asap-supplies.com/seagull-dockside-pre-filter-system?nosto=frontpage-nosto-recommended

The second was a carbon filter.
