Do you have gray plastic shut off valves and supply hoses under you sinks and toilets? If your house was built in the 1970s to the mid 1990s you could find this type of valve and hose under a kitchen or bathroom sink or possibly under the toilet.
The gray plastic fittings in these pictures are made of polybutylene. This was a standard plumbing fixture valve and hose material from the 70s to to the mid 90s. During this period, there were issues with polybutylene supply tubing in walls and crawlspaces developing leaks and the use of this material was discontinued around 1995. I still run across these type of valves and supply hoses under sinks and toilets. Given the past long term issues and problems with polybutylene piping I always recommend replacing these valves and hoses with modern plumbing parts. Interesting find at a recent inspection. The armored conduit for the electric water heater was just a bit short during installation. Rather than obtaining a longer piece, the installer decided to substitute duct tape to cover the gap. Though it is the same color as the conduit, duct tape does not provide the same benefits as an appropriate length of armored conduit. This is a potential safety hazard for shock and needs to be repaired. Standard building practices call for the power supply wires to be protected with BX armored conduit all the way to the top of the tank to prevent damage. Duct tape is not listed in the building code as an option.
