Gutters – June, 2023

Looks good! (Not)
Gutters are supposed to stop before they touch the siding or trim. By burying the end of the gutter in the trim, any leaks will flow behind the siding and trim, causing damage to the house.

Clothes dryers cause almost 16,000 fires each year in the US. What does your dryer duct look like?
We’re not sure exactly what’s going on here, but it looks like the breaker on the left was tripping and someone “solved” the problem by running three strands of magnet wire to an adjacent breaker. This would certainly stop the first breaker from tripping. Of course, it could also cause the house to burn down.
Each plumbing fixture in a home connects to a drain/waste/vent (DWV) piping system that takes wastewater to the municipal sewer or a septic tank. Those sewers and septic tanks produce gases and foul odors that (unsurprisingly) we want to keep out of our homes. To do that, each fixture’s drain should have a trap that holds a small plug of water to block these gases. The sink in this photo lacks a trap, so sewer gases can enter the living space. Time to call a plumber.
Back in the day, this would have been the house’s “main grounding connection.” It’s where the electrical service was grounded to the house’s steel water pipe. Somewhere along the way, someone changed out the thicker steel pipe for a more slender copper tube. Disturbed rust on the screw threads shows where someone loosened the clamp to change it, but callously disregarded the fact that the old clamp didn’t fit on the new tube. Like the Grinch’s heart, it’s two sizes too small. This leaves the house with a very poor grounding connection to the earth, making it vulnerable to surges.
Our intrepid homeowner switched from an electric range to a gas range. To accommodate the new range, any electrician could easily have changed the old 240-volt circuit to a 120-volt circuit, but our hero came up with a better way: Mangle the old range cord to make an “adapter.” Why is that a problem? Let us count the ways:
A few things are wrong here. The most obvious is the plumbing vent pipe that supports a satellite dish. Our plumbing code calls this “flagpoling” and prohibits it outright. Plumbing vents shouldn’t support any other objects, including television aerials, satellite dishes, and, of course, flagpoles. Flagpoling can cause the horizontal portion of the vent (in the attic) to sag and hold water. It could also cause the vent to break and admit sewer gas, or even water, into the attic.
At the right side of the photo, trying to hide near the edge of the frame, the B-vent is very badly rusted. This vent carries exhaust from a furnace and/or water heater through the roof. When they get this badly rusted, B-vents can develop holes and leak. It’s time to replace this one.
When plumbing a new house, plumbers must pressure-test the waste pipes to ensure that the system doesn’t leak. Leaks might allow waste water or sewer gas to enter the house. So, when the drain piping is complete, the plumber inserts a test plug and fills the drain system with water all the way to the top of the vents on the roof. This allows the plumbing inspector to check for leaks. When this test is done, the plumber removes the test plug, seals the drainpipe, and goes onto the next job. On this house the plumber forgot to seal the pipe.
The test plug is that long black tube below the pipe. It had been inflated inside the pipe for the pressure test and was subsequently removed. Perhaps the plumber then went to lunch and forgot to come back and cap the drain pipe. In any case, someone should install a cap now, before a backup causes sewage to flood the crawlspace.
One of the reasons that home inspectors run so much water during an inspection is to reveal problems like this one. The basement floor drain is connected to the main sewer line, which doesn’t drain fast enough. As a result, some water backs up into the basement. While this might be a sign of a simple obstruction in the sewer line, it might also be a sign that the whole sewer line needs to be replaced.
When one fails or is improperly installed in a way that prevents it from doing its job, a traditional tank-style water heater can behave like a bomb (or a rocket). Here, a flush kit for a tankless water heater is installed upside down, placing a shut off valve between the hot water output and the pressure relief valve. While the small amount of water in a tankless water heater would cause a less “exciting” failure, accidentally closing the valve could still create a dangerous and/or expensive result.
