Wasp infested pipes
Steel pipes are not for decoration. They need to be clear so air, water, or gas can pass through. When the flow gets cut, one is likely to have a big problem. However, most of the time pipes get clogged due to dirt or rust, which has an easy solution.
There is a slight chance no plumber will fix your problem. If what’s clogging the pipe system is a massive hive, you need to call an exterminator! A single wasp sting can be extremely painful, so have that hive taken down!
