Temperature and pressure relief (TPR) valves are critically important safety devices. 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 [...]
A trombone comes to mind... Or maybe miniature golf. Drainpipes under a sink should be simple: a small U-shaped bend called a “trap” holds a plug of water to prevent sewer gas from rising out of the drain. This plug of water should never be more than 4” deep and the remaining drainpipes should be as short and direct as possible. The drain [...]
What is a toilet fill valve? A toilet fill valve performs the thankless task of refilling a toilet's tank after each flush. They come in a variety of configurations, based on the size, shape, and design of the toilet. A malfunctioning one can make the toilet run continuously or fail to refill the tank with the right amount of water. When they're installed too [...]
PVC pipe is a no-no. This water heater has a 1/2" PVC extension tube on its temperature-pressure relief valve. PVC stands for Polyvinyl chloride, but a more suitable name might be “Pipe Very Cracky”. The piping is brittle and not rated for use inside a home generally, and especially not as an extension tube on a water heater temperature-pressure relief valve. In addition to [...]
Duct tape and bailing wire are a short-term fix. Anyone who grew up on a farm knows that much can be done with duct tape and bailing wire, at least to get a job done in the short-term. But repairs made in the short-term are often forgotten and become long-term, permanent, repairs. Here we see duct tape used to repair a gaping hole in [...]
Rule #64 of home inspections: If anyone *can* do their own plumbing work, anyone *will* do their own plumbing work. As we’ve mentioned before, every plumbing fixture is supposed to have one trap to hold a small plug of water and prevent sewer gas from rising up out of the drain. This homeowner must have been one of those people who believe that “more [...]
