carbon filter for the water
- Thread starter hookway
- Start date
Lots of people put in-line filters on their tank(s). Back pressure on most isn't a concern.
Consider the greatest benefits of these common carbon filters is two-fold:
1. Removes odor and taste, and
2. Provides a false sense of safety.
Most home improvement store bought filters are ineffective at removing the 'stuff' that can cause illness. And even if they did, these chemicals and pathogens would simply accumulate in the filter creating worse problems.
Use bottled water, beer, wine or a good scotch, not necessarily in that order.

I'll be sure to CLEAN any filter in that case, if I get one at all.
Incidentally, I do have a backup supply of wine & single malt.
You don't need filtered water to wash dishes, wash your face, shower, brush your teeth or--if your toilet is one that uses pressurized fresh water--flush the toilet. So all you really need is a faucet filter on the galley sink. And you might not even need that if you recommission the fresh water system annually using the directions I've posted to this site at least a dozen times and which has be reposted by others at least that many.
This link should cover the topic. Not knowing your system, practices, or what you a re trying to accomplish, the answer is rather long. As Peggy hinted, there are a number of steps, and filtration is only the last.

If the water is not drinkable, then the system is either poorly maintained or poorly designed.

Bourbon and branch water? Does the Bourbon sanitize? After a few, who cares?______
I have one of these that I use only for Transient Marina water sources, since my current water source is soft and sweet.

We use this filter with the Optional Carbon Filter

Nothing worse than mixing High Sulfur, High Chlorine and unknown water in my water tanks.
_______
What motivated me was Chlorine removal, since I have Aluminum Water tanks [slow corrosion].
_______
Residual Chlorine from a well flush (used) shore water line, does little for sanitation in your boat's tanks, after you release the source line pressure. This is the reason most boaters flush and sanitize their tanks, frequently.

#1 Our tanks are fulley cleaned and the system 100% shock sanitized each srping.
#2 Our tanks NEVER have antifreeze in them.
#3 Our water is pre-filtered before it goes in the tank.
#4 The water is treated in the tank.
#5 We use this filter housing on the supply side of the pump;
#6 We use this filter in the housing:
#7 We additionally filter with a Brita on-faucet filter.
#8 We send the water out for testing at least once per season. It has always tested as 100% safe & drinkable..

Same as my Post# 8 link, but different Manufacturer. I just do it before going in my tanks.

One of the most important steps is to let the water run long enough to clear out all the water that's been sitting in the dock supply line in the summer heat before filling the tank.
Yup. Always take a few minutes to rinse off the deck, anchor, or something before filling. Easy.
For what do you have it tested? It may be more informative to post a pic or PDF of the results

Therein lies the problem that creates the false sense of security imentioned before.
Most municipalities do the minimum required to meet Federal water quality standards and nothing more. Unfortunately, you could test for those exact analyses on a quart of gasoline and obtain results meeting those standards.
That's why I asked to see the list of analyses people believe keeps them safe. It doesn't.
This is probably an over reaction.
The cause is typically high sulfate content, which is converted over a few days to sulfide by a few bacteria. If you simply treat with chlorine while loading, the sulfate will stay sulfate, which you cannot smell or taste. The chlorine will also convert sulfides back to sulfate, removing most off tastes and odors. The carbon will remove any chlorine residual. This is a particular problem on islands in seawater, which may have wells affected by seawater intrusion (high sulfate).
Which is not to say you shouldn't always inspect the water before loading. But actual "bad" water in the US is unspeakable rare.
