rust in pipes??

Posted by minniemom (My Page) on

HI,
We recently had an addition put onto our home with a 2nd floor bathroom directly above the original bathroom that still remains. Yesterday, after the hot water was running a while, I noticed that the water was tinted brown in the shower, then in the sink as well. When I mentioned it to my grandmother (who's house it was originally) - she stated that it has happened before. All of the research I have been doing, tells me it could be old water heater. But ours is brand new. I am thinking that it may be the pipes leading into the house from the ground. Because it happens in both the original bathroom and the new one. When I run the cold water, it dosn't happen as much, mostly the hot. Sound familiar to anyone.
Thanks,
Jennifer

RE: rust in pipes??

Rust can occur in any iron pipes or vessels in the water supply system. This could be old galvanized iron piping either in the supply line from the municipal main or well to the house, an old iron well pressure tank, a water heater vessel or an old expansion tank.

As a rule the rust is affixed to the pipe or vessel walls fairly soundly and it doesn't move much but whenever the water is shut off and the system drained for maintenance you can expect some of the rust to be dislodged when the water is turned on again.

Generally if you let the water run about 20 to 30 minutes it will flush clear.

Aside from being very unsightly it generally does not pose any serious health risk.

Sounds to me that you have old galv. pipe where the new addition is connected, there is no way to fix this without getting rid of the galv., that means that it all has to come out including the underground supply. Sorry for the negitive, lots of luck.

I am assuming you are on well water, right? Nearly all natural water sources have some iron in it. If you have city, rural or any other centralized public water system, then another solution may be required.

What is iron as far as water treatment is concerned? Iron can come in a number of ways: Ferrous, ferric, bacterial/organic, or colloidal.

Ferrous (clear water iron, soluable, fe++, dissolved) iron comes from the ground clear but is still present. It will cause no iron problems as long as it remains dissolved, except maybe for odor and taste. But as soon as it becomes Ferric (rust, ferric-oxide, insoluable, Fe+++, solid) iron is causes stains and can become more than just a bother.

Bacterial (iron reducing bacteria-IRB) can most likely be seen in the toilet tank as a slimmy, gelatinous muck on the wall of the reserve tank. Take your finger and slide it across the tank's wall, if it feels slimmy and comes off on you finger, chances are you have bacterial iron and chlorination may need to be done, initially.

Colloidal iron is rare and very difficult to remove. It is notied by a slight rosey tint to the water and its specific gravity is so similar to water that it doesn't easily settle out. Think of milk as a colloid: how long would it take for the milk to seperate from the water and settle to the bottom of the glass?

Most likely you have ferrous iron. If is oxidizes, it will turn to rust.

As mentioned before galvanized piping can create iron problems. Look at the pipes on your water heater. Many companies still use galvanized pipe (about 2" in length) at the top of the heater. Also, it may be found near your pressure tank.
