"Kirkwood Plumbing was very responsive, sending a highly qualified technician within 24-hours. He did an incredible job replacing old cast stacks and vents to our 2nd floor bath. The further comment that I would make is they are not cheap. I'm still trying to reconcile their cost for a 7-8 hour job, but the results couldn't be better."

"Everything about this repair job was wonderful - from Brad giving us the bid (and explaining exactly what would be done), to Will and Ree (sp?) doing the excellent work. Everyone was courteous, professional and left everything spotless. And the cost was surprisingly lower than I thought it would be."

"as installed in 2010, which is correctThe plumbers did arrive about 1 hour and 40 minutes into the 2 hour window.  I explained the problem.  They asked me to show where the drain went in the basement.  They estimated it was about 55 feet from the kitchen sink that would need to be cleaned.  They said they would perform a whole house plumbing inspection while there.  While one plumber worked on the drain the other checked for natural gas leaks, there were none, and checked the water heater.  They told me the water heater was installed in 2010, which is correct.  He also told me the anode rod needed replacing.  I googled anode rods and found 2 references from plumbing supply companies that verified everything he told me.  They also sold me an enzyme to maintain the drain.

French Drains FAQs, answered by experts

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.

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

Yes, pop-up drains commonly get clogged with hair, soap scum, and toothpaste. It is important to know how to properly clean the drain or get professional help to ensure it remains clear and can drain water effectively.

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.
