I've previously treated my tank with a Whale carbon filter and treated the tank with chlorine tabs (https://www.piratescave.co.uk/aqua-clean-tablets-midi-box-x-32.html) when I filled up. This led to a nasty taste from the water, as when I was filling up the tank from say, two thirds empty, I would treat the whole tank again (60 liters) with two tablets. I guess that led to a build up of the taste.

On my new boat, I've considered using the below to try and remove that chlorine taste and offer another barrier to any foul water.

Or could I get away with not using the chlorine at all? My water tasted so much better before I did anything with it to be frank - and we never got sick! :rolleyes:
 
A very good question having played with water quality from the tanks.

As we all know usually the trouble is water left standing for relatively long periods (between boat use) which often go away when it is being used daily. Very often the problem is micro-organism build up in the pipes - not a problem with the tank itself.

The quality of the water put into the tank in the first place is also a consideration.

I now do the following. I filter the water going in. I use a carbon filter, water softner and micro-filter. This takes out a lot of the contaminants, and stops the bulid up of scale. I then have a T valve immediatley after each tank. Every so often I run a few litres of hot tub shock solution throught the pipes (I use this as it is pure belach without any additives and comes in granular form) leave for a short while, and then run off some water.

That keeps the water pure and sweet and I dont use anything else.

I think filtering the water first could be dispensed with and there is an argument that the carbon will remove some of the chlorine in tap water and it is worth adding a little back if you are pre-filtering (but I dont).

Am I understanding that you put the water through a carbon filter and then treated it with chlorine? This is backwards and explains the result.
* Particle-only filter to keep crud out of the tank. If a tank has a layer of crud in it good taste will be a challenge.
* Chlorine in the tank both for bugs and taste (off-tastes are generally caused by sulfide in the water, which chlorine oxidizes).
* Carbon filter on the way to the tap to remove the excess carbon. Carbon is very efficient at this.

In the UK I'd go with Daulton Supercarb.

We have a General Ecology filter on the boat in Greece. In general it seems to work well, improving the taste of water from the tank, which is the only source we drink. However, in mid-summer the water on tap in the marina becomes brackish, presumably with dissolved salts as the aquifer level falls on the island. The GE filter does not remove this taste.
 
For general prevention and decontamination of potable water supplies on board, I use Endosan products.

https://www.endosan.com/


It's a mix of hydrogen peroxide and silver. No taste of chemical at all. It prevents algal and fungal buildup in pipework and tanks/ I use it for agricultural spraying on a commercial basis, and somehow there is always a bit left in a bottle for the boat.

As a general disinfectant for the galley and heads and bilges, it cannot be beaten, I give a quick spray round with diluted product when leaving, and the boat never ever whiffs when I return.. The spray bottle is used on humans for scratches and grazes, too.

No affiliation with the maker, just a very satisfied customer,

Oh yes, you have to a bit careful with undiluted product of the strongest (50%) liquid, but otherwise a spray bottle and squirty bottle are on board and available at all times and for use by anyone.

I also use it on sheeps' feet for foot rot.

I sounds as though you are over doing the chlorine.

I usually treat the first fill each season with Milton at the rate of 2.5mls / 5 litres. Provided that is not exceeded it is fit to use after standing for a short while. If the dose is increased it tastes of chlorine and tea made with it tastes horrible but at that dose it is fine

( In practice I part fill the tank, add the Milton and run a little of the more concentrated stuff through the pipework before topping up the tank )
 
I fill up my s/s tanks with tap water having run water through the hose a bit to remove any stale water. One of my tanks has a general ecology filter system for the drinking water (replacement cartridges are expensive). I find that if i'm boiling the water I don't use the filter tap. I used to clean the tanks each year but have reduced that to about every 2 or 3 years. the water does taste better with constant use though.
 
I always empty my tanks before leaving the boat. When refilling i allow the taps to run water for a short while. The boat is currently in Spain and i dont use any chemicals. I tend to use bottled water for drinking and tap water for cooking never had any bad smells or problems with the water.

Nope, we treat with the tabs in the tank and then we carbon filter under the tap. However, I think our dosing with every fill up overdosed the Chlorine as Vic suggested.

+1 - as good as the GE Nature Pure but a lot cheaper for both the installation and the replacement filters/candles.[/QUOTE]

Ah, one of these chaps?

https://www.finerfilters.co.uk/fine...n-ultracarb-imperial-obe-w9223006-filter.html

That seems a better price! I'll run the tank cleaner through all pipes etc, fit one of these (if thats the right one) under the galley sink, filter the water on fill up, and only dose with a little chlorine on first fill of the season. Then just do lots of sailing and using of the water to make sure its rotated.
 
The time has come to fit the water filters to Mirage. Based on the above, I was going to go with one of these:

Finerfilters 10” Clear Housing with ¾” ports, Pressure Release Valve and Doulton Supercarb Imperial OBE (W9222909) Water Filter Finerfilters

So my Bavaria has Whale 15mm pushfit plumbing, and the above has 3/4" BSP threaded ports. My plan is to cut the cold feed under the tap in the galley and insert the above. What fittings would you suggest to connect the filter housing to the plumbing? What I've come up with is below:
Does that make sense? Or have I over engineered this... (as usual)...
 
I would use an opaque housing. It will be more durable, cheaper, algae can't grow in the dark, and you can't judge the condition of a fine filter visually anyway.

The Subercarb filters are great. They remove cysts and chlorine. I wish they were more available in the US. I also like that you used a standard housing, so that you are not bound to a proprietary refill.
 
The filter was eventually fitted, we had a few leaks to start with whilst I learnt how to use the push fit stuff, and I ran out of the Whale fittings I purchased and needed additional pipe. A quick visit to Screwfix later for their 15mm fittings saw the set up complete and at a fraction of a of the Whale stuff - although the fact the pipe isn't blue offends me, so I will likely swap it out once the boat is delivered back.

On the 10 psi pump, the flow rate is right down, however, when the pump itself runs when the pressure drops, it does push it through a bit faster. It is more than fast enough to draw a glass of water - and it tastes amazing!

Does anyone use a higher psi pump?
