"We had a plumbing emergency after regular business hours when a toy got stuck deep in our bathtub drain. I called Mr. Rooter Plumbing of North Miami Beach, and to my surprise, technician Jose was at our home within an hour! He was incredibly professional, courteous, and took the time to explain everything before starting the job. Not only did he quickly clear the drain, but he also managed to rescue Chase from Paw Patrol—which made my son’s night! Having their main office so close to us in Bay Harbour is a huge plus. I highly recommend Mr. Rooter Plumbing of North Miami Beach to anyone in the area. Excellent service, especially when you need it most."

"Romain's Plumbing is the absolute best! We had a very bad leak in our 50 plus year old home that two other plumbers could not fix, pin point nor identify. He was able to troubleshoot and find exactly where the problem was, explain, figure out, fix and repair everything quickly and efficiently. He is honest, trustworthy, hard working, and most of all reliable and fair. This is the number one Plumber in South Florida!"

"Called John's after finding their ad in the local newspaper.   We also called another local plumber, but went with John's after they sent someone out immediately to look at the problem and give us an estimate.  We scheduled the repair for the next day after getting what we thought was a reasonable quote.  Brian, the same person who had come out to inspect problem, arrive early today to fix the leak.  He was respectful, friendly, and diligently worked to fix the problem.  We are very impressed with everyone we spoke to at John's and the great service we received!  We would not hesitate to use them again and  will be recommending them to all of our friends.  "

"Shortly after buying our new home, we noticed some plumbing issues—specifically, yellow water coming from the laundry room and kitchen sink. Just an awful start to being a homeowner. At the very least, Joseph came to the rescue. He was quick to respond and resolved our first headache as homeowners. Definitely recommending to family and friends in the future!"

"Very pleased to have found Matt. He was quick to respond to my solicitation and set up a walkthrough after our first conversation. I had an odd flooring issue that was driving us crazy, he said it was indeed odd and that he would need to do some troubleshooting. We set an appointment for the work and he arrived on time. He was able to determine and resolve my issue and did several other jobs around the house. He is knowledgeable, skilled and courteous. Will be hiring again soon. Thanks."

Plumbing questions, answered by experts

You’ll need two sizes of pipe to plumb a bathroom. You’ll use a 1/2-inch pressure pipe for your supply lines that run from the fixture to the larger 3/4-inch supply lines that run through the house. For drain lines, you’ll need a 3-inch PVC pipe for your toilet, a 2-inch PVC pipe for stand-alone showers, and a 1 1/2-inch pipe for a shower/tub combo and the bathroom sink. Each fixture’s drain will run to the 3-inch main drain that runs through the house.

Yes, frozen pipes can prevent a toilet from working correctly. If the pipes are frozen, water cannot flow, which means your toilet tank won't be able to refill after a flush. This will prevent the toilet from flushing again. Depending on which lines are frozen, the ice can also block the drain pipe, preventing water from flushing away.

As a temporary workaround, you can manually add water to the tank for each flush. To clear a frozen drain pipe, you can try filling the toilet bowl or tank with warm water and flushing to help thaw the ice. However, the best long-term solution is to unfreeze the pipes to get your toilet back in working order.

If your pipes are suddenly making loud noises, it could be due to any of the aforementioned issues. A water hammer is a common cause of this problem. Other potential causes include water pressure issues, loose pipes, air bubbles, and worn-out fixtures. Mineral buildup in the pipes can also cause loud noises. 

According to the Uniform Plumbing Code (UPC), the distance between your trap and the vent should be no more than 6 feet. For your vent to work properly, it needs to feed into the drain line within 6 feet of trapways that connect to it. Using this formula, you should be able to determine whether you will need multiple vent lines.

Basement toilets don’t always need a pump. However, it is the most common setup because plumbing systems use gravity to move waste away from the home. Basement toilets often sit below the home’s main sewage system, and installing a sewage ejector pump pushes the wastewater and sewage up to the main sewer line. Alternatively, you can use an upflush or macerator toilet that breaks down the waste and pushes it straight to the main sewer line rather than via a sewer line from the bathroom.
