"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."

"Installation went smoothly. I've had the system for about 5 years and I recommend it highly. The water tastes great. We don't buy water anymore. Our pipes are protected from mineral buildup. Very pleased with our purchase."

"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."

"I'd been having a problem with the toilet draining in my guest bathroom for a long time.  Soon it became apparent that the sink and tub were also having the same problem---the entire bathroom wasn't draining well.  Multiple plumbing companies had come out and multiple things had been tried, to no lasting avail.  Due to a previous hydroflush and camera I knew there were roots in the line and that was possibly the problem.  So when I saw the 'deal' for $300 for root removal and flushing, I called them out.  They spend quite a bit of time cutting the roots and flushing.  However sadly that didn't fix the problem.  The bathroom in question was at the farthest end of the plumbing line.  So I called them back out.  A different person than the first person came out.  We had to knock a hole in the wall to access the toilet clean out but once that was snaked the toilet worked well.  However then he had to use the sink clean out to help the sink to drain.  Then he tried to snaking the tub, but was unable.  As the tub did drain (even if a bit slow) we decided to leave it at that as it is my guest bath and not much used.  The extra work was $275.  However it has now been over a month and everything is working well.  We are SO pleased to be able to use our toilet again after many months of non-use!  Both of the people who came out were very polite and professional.  I would certainly use this company again.

"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, you can install a farmhouse sink on an existing countertop—but there are some caveats. You’ll need to precisely measure. It’s best to choose a sink that’s the same dimensions as your existing sink, since your contractor won’t have to cut the countertop. Otherwise, pay close attention to the depth of your counter (the front to back measurement). You don’t want to install something that’s so big it sticks out beyond your countertop and cabinetry.

When installing an undermount kitchen sink in a granite countertop, use 100% silicone to secure the basin. If you’re worried your sink is too heavy, speak with a countertop professional about how to adhere the sink to the countertop without worrying about issues down the road. Sagging undermount sinks can be a common plumbing problem if they’re not properly adhered, so always make sure you’re using a high-quality material.

Local plumbing codes and manufacturer recommendations typically dictate the minimum distance between a sink and a dishwasher. This is generally 18 to 24 inches, providing enough room for easy loading and unloading of dishes without hindering the sink's function. Maintaining this separation not only adds convenience but also reduces the chances of water damage and optimizes plumbing connections.

Yes, you can use flexible pipe for a sink drain. Flexible pipes can make it easier to fit sink plumbing together with less measuring and fewer cuts. However, corrugated flexible pipe can trap hair, grease, and food particles in the folds and cause foul odors and eventually build up enough to clog the drain. Smooth pipes are recommended for sink drains and plumbing.

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.
