"Zoom Drain showed up as scheduled. My technician was highly professional and explained the drain clearing process and options to me. They quickly and professionally cleared my clog without making a mess in my home. As I was concerned that my clog was an indication of a drain collapse or tree root issue in my lateral, I chose to have or my drain scoped. Their excellent drain camera gave me a great view of the condition of my drain piping. It was reassuring to see that this was a â one offâ problem and that my drains are in good shape. Will definitely recommend Zoom Drain to my neighborhoods."

"We built our house 20 years ago. We discovered the master bathtub was leaking to our family room. Glenn tried to just reseal the drain but found our builder used the wrong materials and didn't properly configure it. Glenn apologized for having to cut the ceiling to get to the pipe that needed to be replaced but finished the repair quickly and cleaned up everything. I would definitely recommend Glenn at Hosack Plumbing to anyone needing plumbing help."

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"

Drain Pipe Installation FAQs, answered by experts

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

It’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

Baking soda and vinegar aren’t just great for making a volcano for your kid’s science project. You can also pour this dynamic duo down your shower drain to dissolve hair clogs. If that doesn’t do the trick, you can step it up with a commercial liquid drain cleaner.
