"Derek helped us out with some plumbing on our food truck. He installed a three compartment sink and fixed drains under the truck. He responded to our call right away and came out the same week. He was thorough, made sure to have everything that was needed and went above and beyond to help us out. He was confident and I trusted he knew exactly what he was doing. He got the job done quickly and efficiently. Would definitely recommend! Thanks so much!"

"Noel showed up on a Saturday and unclogged our kitchen sink in an hour. We had tried everything we knew to do and even took all the pipes apart under the sink to try and find the problem. When we couldn't find the clog we decided to look for a professional to help out and we called Noel. He and his employee were awesome. They replaced all of our old pipes and snaked the lines to the outside And all for under $300. We will definitely use him again and are planning to use him to power was all of our pipes soon."

"I have used Don with D'White's plumbing multiple times for all of my plumbing needs. Once I had a clogged sewer line that somehow Don was able to accurately locate a broken pipe , in my front yard which he then dug a trench and replaced the pipe. Don has replaced my water heater, including replacing wood caused by water damage underneath the heater. I have had clogged sinks which he has cleared quickly at a very reasonable price. I have been so happy with D.White's plumbing that I have referred him to my family members and friends for their plumbing needs."

"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."

Sink Installation FAQs, answered by experts

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.

Yes, you can fit a vanity unit to an existing sink, especially if you plan to custom-build the vanity. With a prefabricated vanity, you’ll likely need to make a few adjustments. It depends on the type of sink, the size of the sink, and the existing plumbing. If you plan to retrofit a sink into a prefabricated vanity, make sure you take precise measurements and that your sink is compatible with the vanity you select. Prefabricated units have a precut sink hole, so you’ll need the size to match your sink.

Tools include pipe wrenches, plungers, and augers. Professionals use advanced equipment for complex issues.

Yes, plumber's putty ensures a solid bond between the drain assembly and sink. Silicone is a good alternative if you prefer not to use plumber's putty. However, plumber's putty typically isn't visible from the outside of the drain, as you can wipe away any excess when done.

Basic replacements can be done DIY, but professional services ensure proper sealing, leak prevention, and plumbing adjustments.
