"We have been Will’s Plumbing customers for over ten years. They have replaced several water heaters, a water softener, installed a new toilet and today William “Junior” repaired a water line leak in the front yard. We have always been pleased with their work, they do it right the first time. Their employees are responsive, professional, knowledgeable, and courteous. They send a plumber within hours of our calls. They arrive on time, explain the work involved, answer questions, give a solid price quote, and clean up when the job is done. It is without hesitation that I recommend Will’s Plumbing & Testing Service and ask for William “Junior” Krashoc, it was a pleasure having him on the job."

"This is a review for Patrick S at A & A Plumbing in San Antonio, Texas. We had two sinks in the same bathroom that were draining slowly. This was not an emergency, so I made an appointment for two business days later. The person on the phone was polite and helpful and did a good job explaining the company policies about the service charge (about $20) that is credited towards any work done and what to expect when the plumbers came. I was given a 4 hour window and they came very near the beginning of the window. They called in advance to confirm and then again to let me know when the plumber was actually on his way and the name to expect. When Patrick got here, he gave a description of what was the likely problem and a quote to fix both sinks at once as we agreed the problem was probably past where the sink drain pipes joined up. He promised to talk over any surprises he found before doing anything extra, but his diagnosis was correct and they had both sinks draining wonderfully in less than an hour. Patrick and his colleague were pleasant and left everything as clean as when they came. They did not push selling me extra services, although they did ask if I had any other issues. I felt the price was fair for the high quality service I got. I will use this company again if we have another plumbing problem."

Drain Cleaning FAQs, answered by experts

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

No. You should dispose of all oil-based finishing products through a local hazardous waste program. Not only can oil-based finishes be hazardous for the environment if disposed of in the sink, but they can cause clogs in your pipes and stop up your drains. Most municipal garbage or waste disposal companies have a specific location or pick-up schedule for hazardous materials, so that’s your best bet to get rid of excess finishing products.

Yes, drains are one common entry point for water bugs. However, water bugs may enter your home through various locations including doors, windows, pipes, and vents. Water bugs are drawn to the dark and moist atmosphere drains provide, and can easily find their way into your home through sewer drain pipes. You can stop water bugs from entering through drains by regularly cleaning your drains and repairing faulty drainage systems.

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.

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.
