Older heater with rust build up in the bottom of the tank.
The most usual cause for brown water in the bath is a growth of algae in your hot water tank; it could also be rust in the hot water tank. The simplest solution, although very expensive, is a new hot water tank. Personally, I would be willing to bathe in brownish water.
Yes it would cause it has water in it
Hot water tank needs bleed of air,
Hot water... sometimes semen.
hot water is hotter cause hot water is always hot
water pump, oil, water, engine coolant....main cause would be engine coolant, just check to see if you have a leak.
No. The glass of the beaker, since it is hot, not cold, would not cause the ambient moisture to coalesce on the glass
My first thought is a leaky hot water line.
If it is a electric water heater, then one of the heating elements are burned out.
This could be rust particles from your hot water tank. This is not healthy and you should have a plumber check this out.
If the water or soup you are putting your dumplings in is not hot enough it can cause them to fall apart.
Lots of stuf can cause it including sediment or a blocked supply line
