What have I been drinking?

[sahona]

In the process of re-doing the pressurised system to tidy it up and make it more accessable.
Some of the pipes were put in by me last year, and should be re-useable, however, I cleaned them anyway.

I was surprised and disturbed to see the black gunge emerge on the pull-through. (but we haven't been aware of any associated medical problems)
What do the rest of you put in the water to stop this - sodium bicarbonate?

Me thinks you need a plumber Bill.
Havent had my water tank in long enough to get to that stage, besides I dont use the tank for drinking or cooking water, just use bottles.
What about Milton fluid?

Testing the subframe:
1. Connect garden hose.
2. Stand back

Look - no fountains ! (have to admit this is not the first attempt...)

Now it's sitting in the garage using the 12v pump to pressurise, with a tiny fuse in the circuit so I can detect and pre-emptively repair the cause of "nocturnal pump burps". (the fuse will be blown if the pump attempts to start)
The other pump is for the deck hose.

As we live aboard all the time we have found this problem quite alot. Our way of stopping it almost completely is when filling the tanks we use a funnel (not the diesel one) which we line with about 6 layers of a fine cotton material then pass all water through this then we charge the tank with TANK PURE drops we have had no problems with the water since. You might also try fitting an AQUA FILTER in the line for drinking water this gives you bottle quality water. We have tested this system and have found that the filter will last about 9000lts well above the recomended amount. Hope this helps.
