Charcoal from water filter?

travelingjw · 10-23-2020, 09:01 AM

We have started noticing a spurt of black water when we turn on our faucet after hooking up. I flushed the system and purchased new filters (Camco in line blue filters). This morning after a freeze I run the hose to clear the air before I hooked up and a black spurt came right out of the filter. Anyone else see this?

By flushing the system, do you mean you sanitized? Black algae in the hot water tank or other locations in the system for that matter? Have you left water sitting in the tank? Also, even though you drain water supply tanks, there is always a small amount of water left. It grows bad things between uses.

I accidentally left water in the tank between uses. What came out was about 6 gals of black, and I do mean black water. Water left sitting, especially in our temps here, goes bad pretty fast.

I didn't sanitize, I just ran water through every faucet to assure that any "matter" would be flushed out. The black spurt only comes out of the sink nearest to the city water inlet. When we get home I am going to disconnect the P-trap and check the low point. But the fact that I had a black spurt prior to hooking up this morning makes me suspicious that it is charcoal from the filter. This is also because the color is dark black, not "mold" black.

How new is the filter? Is the filter located at the CG hose bib? Are you using one of the Blue RV filters or do you have a whole house filter with independent filter cartridge. Did you shake it to get all the water out when you drained it?

My experience with whole hose filters, it is not uncommon to get charcoal fines out of them when I first add water.

Thanks, the filter is brand new. I place the filter right at the inlet to the TT. It is a Camco blue filter which we have used since we since we purchased the TT. I purchase 2 and swap them out in the middle of our traveling season.

My experience I always get charcoal dust out of a new filter. My home filter cartridges instructions, state to run the closest faucet for a minimum of 5 or 10 minutes to flush out the charcoal dust.

I get that black spurt EVERY time I hook up my Camco filter, even when it's been used before.

It's a burst of charcoal from the filter.

So, before I hook up my hose to the rig, I first blast out the hose bid and let it clear. I've had dirty water come out the hose bib when first turned on. Then, I hook up my pressure reducer, blue filter, and water line, and turn the bib back on to flush the hose and filter. I ALWAYS see a black spurt come out, even after multiple uses.

Once I let it run clean for a minute or two, I turn off the hose bib and attach to the rig.

I did the same thing the first time I hooked up a new filter to our TT. I didn't flush it first, and the charcoal dust went through our plumbing. It got into the water heater, which didn't impress the DW when she went to take a shower. It looks bad, but is harmless. Just another learning experience in the world of RVs.
