My house is about 55 years old. We recently had our basement floor partially excavated to fix a portion of the waste water piping. The old clay piping had shifted, causing a blockage and backup into our basement. We found the broken clay piping and replaced it with PVC. All good.
Twenty four hours later, we're having dirty water off and on through all of our faucets and showers. The plumber says that with all of the digging during the basement excavation, they knocked loose some of the sediment that has built up on the inside of the copper fresh water line.
The fresh water and waste water pipes do run a few feet away from each other, and the excavation was pretty intensive, so I see this as being feasible.
Does this explanation fly with you guys? Any suggestions? The plumber said that it should stop in a day or two.
