"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."

Customers say: Quick response

"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

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Bleach—even diluted bleach—is not always the safest option for cleaning your drains. With a high pH, bleach can be highly corrosive to many types of pipes, especially when used regularly. When mixed with household cleaners and organic waste, it can also create dangerous chemicals. Remember to use proper protective equipment and ventilation when dealing with bleach.

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.
