Plumbing FAQs, answered by experts

Switching to city water from well water requires running a private main service line from the closest main city line to your home. When comparing well water versus city water, city water is routinely tested and readily available but can be more expensive than well water.

You can adjust the mixing valve on your shower if it uses a single handle to control both hot and cold water by removing the handle and adjusting the cap on the mixing valve. The cap fits over the valve handle and creates a low and high point for your handle to spin. Remove the cap and turn it to adjust how it mixes hot and cold water, and then replace the cap and reinstall the handle.

Problems with a damaged handle or valve cartridge can result in a leaking faucet that won’t turn off completely. The faucet may also be rusty or corroded, which can prevent the faucet from turning the water off all the way. A leaky faucet can cause issues beyond the annoying dripping sound. It also wastes water and can be an indication that something else is wrong with the system, so fix a leaky bathtub faucet as soon as possible.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

In most cases, you can’t connect to an existing sewer line, but this is specific to new builds and additions. For example, if you add on to a home or build an ADU, you'll likely have to install an entirely new sewer line. In most places, connecting new lines to an existing line is not up to code. As such, most new home builds or additions will require proposals for an entirely new line from the construction site to the sewer.
