Good day!
Yesterday, I removed my 26-year-old dishwasher because a new one is being installed today. Beforehand, I turned off the main water supply as a precaution and drained the remaining water from the lowest outlet point. I wasn’t sure if the shut-off valve was completely tight.
I then screwed on a blank cap and sealed it with Teflon tape, just to be safe. When I reopened the two main valves, yellow-brown water came out of all the taps on every floor.
The situation cleared up quickly, but I’m still wondering: where did that water come from? It seems that by shutting off and draining the system, I mobilized some stagnant water that had been sitting there for a long time and was now released. I tend to think it originated from the hot water side.
The house is as old as the dishwasher.
Does anyone have an idea? Many thanks!
