Geoff,
Nothing is bullet proof. One water tank is not acceptable with or without a
watermaker. There are a myiad of things that could foul the contents of a
water tank and a watermaker is just one of them. With two tanks and a
failure, you have a back-up. Make space, generate a second tank and direct
the output of the watermaker to just one of them with a transfer pump that
can move contents from one to the other. Just consider that you are 10 days
from the nearest water supply and your only, very ample water supply becomes
contaminated and your plan is?

Steve,

How are you claiming that watermakers fail? The only failures that I've
heard of are by cracking the membrane due to over pressurization or
sudden pressure change. In general they fail when someone hasn't
pickeled the system and then you don't get much output or the TDS is too
high. I've never heard of one failing during a production run.

I always check the TDS meter at the start of the run and at the end of
the run and I always see better TDS readings at the end. I pump
directly into my main (and only) tank and have never had any problems.

Peter,
You have received some pretty good responses to your query, but what
troubles me is your query. Please tell me you are NOT pumping the
output of your watermaker into your main water tank, because it very
much sounds like that is what you are doing. Please be aware that
these watermakers fail and that their failure can contaminate the
output. It is always wise to use an intermediate tank and then do a
manual transfer after checking that the generated water is OK.

Hi,
Does anybody know if an activated charcoal filter removes chlorine
from fresh water such as that taken on board from municipal supplies

I read the following within an article in "Ocean Navigator" - online

"A charcoal filter is also required to prevent chlorine in water from
dockside sources getting to the membrane. It should be placed in the
system before the watermaker when tank water is used during
backflushing."

Further, I have had an activated charcoal filter for drinkable water
using the cartridge disposable household plumbing in-line filter for
years but have no idea as to how often one should change them.

Anybody know?

regards
Peter
