We had a new well pump installed yesterday. The well is 650', Goulds 7gs15 pump at 600', static level 150'. The installers chlorinated the well and washed down the sides of the casing for 30 min. The water was clear when they left but was dirty this morning. We didn't use much water that night,(shower, toilet). I don't know if it is dirt sediment or rust. We have lived here for 8 yrs and never chlorinated the well ( didn't know we had to). I ran two faucets and a outside garden hose for 1-1.5 hrs with no change in water color. Any sugestions on what my next step is or if this is normal? Thanks.
Have you had rust stains in the house or do you have a softener or iron filter? If so the discolored water is probably caused by oxidized ferrous iron particles called ferric iron, or rust.
The reason it didn't show up until the next morning is probably due to it taking some time to oxidize the iron or they didn't run chlorinated water into the house after shocking the well and/or the volume of chlorine was too little or, only now is it cleaning rust out of the plumbing.
If you don't smell chlorine in the water, then it's probably dirt being stirred up by the new pump or maybe some pressure water leak spraying the inside of the well. If you have any water treatment equipment you need to by pass it or the chlorine can damage or ruin it; especially softener resin.
BTW, shocking a well usually causes this type problem and can cause the pump, power cable and drop pipe problems; especially galvanized pipe. If you have galvanized pipe, that would take a few hours to cause it to start rusting and discoloring the water.
You don't have to shock your well but anyone you hire to work on it is usually required to shock the well. As if there is no problem in doing it; your government just wants to help you...
Be careful of running water out a hose forever. You should monitor the flow so you don't run the well 'dry' and damage the pump etc.. And running water like that can cause discolored water too.
