I have a tenant in an old building that has been having an issue for the last few weeks, most of the building is copper. It's the only tenant with this problem so far, also the tenant is on the main floor of the building and the other tenants on the same floor haven't reported this issue....The tenant has been at this building for over 20 yrs and only recently has this been happening. The tenant comes in during the morning and leaves for the night after evening time.
When they use the cold water sometimes air and water comes out of the tap and spits out brown water, after a few minutes of the water running it turns clear again. This will happen randomly several times during the day. I checked with the city and no work has been done on the main lines and we are the only building on the street to have this complaint.
Why would air be in the cold water line? With the hot water line the tenant says is not problem, but I heard that air from the hot water tank can go into the cold feed line and move inside the system could this be causing the problem. Also, the building is on a radiator heating system but there is a check valve (one way valve) for the cold feed line for the heating system so I don't think that is causing the problem.
I would assume air is getting into the system and disrupting the lines causing the brown water sediment problem....any suggestions I should try besides redoing the entire main supply line?....
