"Noel and his helper showed up on time and brought in their equipment, protecting the floor area around the sink with a large mat. He patiently worked to break down the clog, which was extensive and sludgy. After the clog was fixed, he checked for leaks and cleaned up thoroughly, leaving the area looking and smelling nice again."

"Art was extremely helpful and accommodating at every step of the project, from bidding through scheduling and even some additional work we needed a few weeks later. The team worked efficiently, doing a new main line install (going under our sidewalk and concrete without any demolition), re-piped the horizontal pipes under the house with copper (they were 100 year old galvanized), and setup a new shut off and regulator outside. They did everything in a day and cleaned up nicely. When we had other contractors working on our foundation 2 weeks later, they bent over backwards to get plumbers out the next day to make some fixes to drain pipe and at an excellent price. I got quotes from three companies and Repipe Pro was the most competitive and also great responsiveness from Art and his wife Thelma who run the business. To anyone looking for a repipe of a home or new main line or having drain work done, I definitely recommend contacting Art at Repipe Pro."

"I need drains cleaned from tree roots 1x or 2x a year. This is the first time I have used DrainCo. The office coordinator, Star, was so courteous and helpful. Great attitude, service; very prompt (even early!); 1st guy did not have right sized rooter blade - no charge! They sent another right away and he did a thorough job on oak tree roots! Highly recommend DrainCo for drain cleaning!

"Service was wonderful, we needed help on a Sunday, and Jose Garcia came to our house and did a quick service. We thought it was a quick fix, but the next morning it started to back up again. We called that morning, they came out again and was told that it would be more work. Two more worker, Oliver and Jesus, came the next morning and by 2pm, all the work was done and my bathroom was cleaner then what they had walked into. I will definitely be using them for any future needs."

"This is the third time I've used them. The first time they straightened out another plumber's mess, and then two other events that occurred. They're very punctual; when I called them on the weekend they were still able to send someone out on the same day. They're clean, they work fast and their rates are excellent."

"In 2013, AAP replaced my toilet with a new one (that they recommended). Over the past 4 years, that toilet has plugged up 6 times and I had to pay $125 each time to have AAP unplug it. I complained that they obviously installed a terrible quality toilet. The manager agreed to replace the toilet with a new one that was better quality...for free. No cost for the toilet or the labor to install it. Although I was pretty angry that they recommended a terrible toilet, I appreciated them replacing it for free. It was the right thing to do. Except for this issue, I have been very happy with AAP's service. They have always been able to come the same day I've called (even nights and weekends). And the service guys are all very nice and capable. I will continue to use them for all my plumbing needs."

Sink Installation FAQs, answered by experts

Yes, a toilet, sink, and shower can share the same vent. This is a common installation method that can simplify plumbing and save space. However, there are important considerations. The vent and associated plumbing must be large enough to handle the demands of all fixtures without compromising the vent's effectiveness. Additionally, the toilet should always be located downstream of all other fixtures. Because requirements can vary and space might be limited, it is essential to check your local building and plumbing codes and consult with a qualified plumber to ensure the installation is done correctly.

Hairline cracks—tiny cracks in the surface—in porcelain sinks can happen due to age, chemical damage from cleaning products, dropping heavy objects on the sink, thermal shock from drastic temperature changes, stress during repairs, and manufacturing errors. Hairline cracks often start very small and grow longer and wider over time. While they may appear problematic, hairline cracks don’t indicate structural problems and may not impact the performance of sinks. However, they can eventually cause water leaks and mold growth if left to grow.

The biggest sign that your flange leaks is if you notice water at the base of the toilet. The cause is likely due to a poor flange installation, so you might have issues with loose bolts, an uneven flange, or a cracked plastic flange. Add a deteriorating wax seal to this, and you have a recipe for disaster. The best solution is to shut off the water valve, replace the toilet flange, and seal it with a new wax ring.

While the drain connection for a garbage disposal is nearly universal and fits standard sink drain holes of 3 1/2 to 4 inches, the size of the disposal unit itself is not. You must have enough space in the cabinet underneath your sink to accommodate the disposal's housing. A larger model may not fit in a compact cabinet or if the existing plumbing is arranged in an unusual way. Before buying a new garbage disposal, measure the available space under your sink. If you are replacing an old unit, it's often easiest to choose a new model of a similar size.

Many parts of your plumbing system can fail, but clogged drains are one of the biggest plumbing problems you’ll likely encounter. From your kitchen sink, bathroom sink, or bathtub, there are plenty of opportunities for gunk, hair, food scraps, and more to get stuck in drains. When this happens, water will slowly drain, leading to standing water, bad odors, drain flies, and other issues.

Many homeowners can handle a minor clog themselves, but if you have a clog in your main line, you’re best off hiring a local plumber to get the drain back to its normal flow rate.
