Plumbing questions, answered by experts

A back pressure valve is a control valve used on production vessels, such as separators, treaters, and free water knockouts. The valve holds pressure until a set point is reached, and then releases upstream pressure to reset. Back pressure valves are not safety mechanisms. Instead, they are regulators designed to keep the fluid, gas, or liquid mixture in a system at a certain pressure level to prevent bursts and other incidents.

Meanwhile, a backflow preventer is a safety mechanism that kicks in when the pressure has already failed and contaminated water flows in the reverse direction. Most backflow preventers consist of two one-way valves, or check valves assembled together. This design only allows water to pass through in one direction but not the other.

The best place for a kitchen sink drain is the middle of the sink. Most people prefer center drains because they allow for better water and waste drainage, and the center location limits splashing because water flows straight down the drain hole. If the sink drain is too close to the edge of the sink, water can collect and drain too slowly. It can also be easier to clean sinks when the drain is closer to the center since debris is easier to wash down and doesn’t collect along the sides as easily.

The life of a shower cartridge depends on the valve type and materials, frequency of shower use, hardness of the water, and the installation process. Brass cartridges can last up to 20 years, while those with plastic components may only last 4 or 5 years. You can replace shower cartridges with plastic components when replacing the showerhead as part of a regular replacement schedule. With a brass model, every 15 years is a good standard to follow.

A hose bib is typically located on an exterior wall of the home, about 6 to 18 inches from the ground or on a deck floor. It will have a top handle that you use to turn the water supply on and off. It will also have a male hose thread, or MHT, on the outlet side, where you would connect a hose.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.
