Water supply issue

[Island boy]

I'm new to the forum and would like to know if anyone has experienced any issues with small black flakes in water lines being trapped in the faucet strainers.I don't know if it may have something to do with the water heater or not. First noticed it after I replaced the two yr old water pump that failed.this is taking place in a 2011 avalanche 330 re.Any thoughts would be appreciated,thanks. Ps Never used city water hookup.

The small, black "flakes" could be pieces of some part of the water pump that broke or disintegrated - such as the impeller. You indicated that the pump had "failed" and perhaps some of the small pieces found their way into the water line.

Since you replaced the pump, are you still noticing debris in the filter?

Sometimes, in new units, you will find construction debris that has clogged up the faucet filters resulting in low or no water flow.

One possibility is that there was trash in the fresh water tank that hasn't been flushed out. Remove and clean all the strainers on each faucet, then fill your FW tank, chlorinate it, run the cold and hot water until you smell the chlorine at each faucet, let it sit at least overnight, preferably 24 to 48 hours, then flush the lines and tank, refill, flush again, and see if the black flecks are still present. If so, then you might consider this:

The inside of the water heater is coated with a porcelain lining. You may have a cracked lining. There are several reasons for the lining to crack and start flaking off:

1. You didn't replace your anode rod as needed and the tank started to corrode which can crack the lining.
2. The tank overheated and damaged the lining causing it to crack.
3. There was enough water remaining in the tank during winterizing that when it froze, it pushed against the lining causing it to crack.

If you remove the anode rod and use a straw to vacuum out the water and sediment, you'll see the small flecks (if this is the problem). There isn't much to do to correct the problem other than replace the water heater tank or the entire water heater.

NOTE: If the HWH lining is cracked and the "flecks" are getting into your water system, remember that porcelain is "glass" and is not healthy to consume, so drinking the water with porcelain in it could be a very unhealthy thing to do. Finding the source of these black flecks and removing them is important.

Thankyou for the input. I'll take a much closer look at the possible water tank problem. I'll post again if I find anything out,hopefully it's just junk from the worn waterpump. One of my concerns was possible bacterial growth. A good sanitizing should take care of that. Thanks again

Hey I B , you should install a filter on the inlet side of your pump.Amazon has SHURflo filter/ strainer #255-313 for around 10 bucks.---Lou---
