Water pipe erosion |
Water pipe erosion can cause copper pipe to fail\Typically copper pipe is rated to last 50 years.But copper pipe can fail due to erosion |

Connecting copper pipe to galvanized pipe does not damage copper pipes.But will cause galvanized pipes to deteriorateAlways use brass pipe when connecting copper and galvanized together Prevent electrolytic corrosion/ deterioration of galvanized pipes and clogs Use 6 wraps teflon tape on threads Buy: Brass nipples at Amazon Brass elbows at Amazon Resource: Low hot water pressure. |

Causes of erosion-Failed anode rod can cause erosion on hot pipe when iron gathers in low spots on pipe. Replace anode rod... inspect each 3 years. Replace damaged pipe.Resource: Inspect and replace anode rod -Water quality can affect erosion. have hot and cold tested separately. -Water speed can cause erosion: Install pressure reducing valve, and expansion tank, re-install smaller recirculation pump. Resources: Pressure reducing valve and manuals Recirculation pumps and flow charts for selecting pump -Turbulence can cause erosion: Pump can cause air bubbles inside the water line. Install air vent -Turbulence can cause erosion: If copper tubes were not reamed to remove rough spots before soldering. Take apart pipe, cut in half, and examine.

Green corrosion at faucetBlue-green sediment at the bottom of water heaterCopper-infused scale deposits within our hot water systemI clean various fixtures by soaking them in CLR to remove deposits and I am surprised by the speed at which they re-form and that they clearly show signs of copper oxide (again blue-green). Our water, while hard (we have a softener), is not particularly high in copper. So the copper must be coming from the interior of our pipes and this "erosion" worries me. Our recirculation system is running a Taco 006 pump on 1/2" pipe and in doing some research I found a copper industry handbook that says the flow rate in our pipes to avoid erosion/damage should be significantly lower (half as much) as what we are getting from the Taco 006. Answer The simple solution would be turn off (or remove) pump and see if green reappears at faucet. This would include or eliminate pump as suspect. Replace pump would be next simplest solution.... but costly as you said. Soldering pipe is straighforward, even for beginner... of course you have to buy torch and solder. How-to-solder-pipes.html |
