"Cody with FlowPro Plumbing did an excellent job in replacing two toilets in our home in Sunset, La. He removed the old toilets and took them away without leaving a mess. While here he also cleared a water line to the bathtub that was clogged with rust. Cody and his helper were very professional, and I would not hesitate to recommend his services."

"It's been about a year since we had EZ Bathe remove a jacuzzi tup and a shower. Then custom design a one of a kind shower and a custom walk in tub. Every day we are excited to have them both. They were fabulous. They adapted everything to fit both size restrictions and size abundance."

Plumbing FAQs, answered by experts

Having the right size pipe ensures proper drainage and helps protect against clogs and other plumbing problems. A pipe that's too small will take longer to drain, which can result in backups. And solids can build up in pipes that are too large. Choosing a pipe with the appropriate volume also means it will be able to handle water pressure, which is the force behind the water.

Adding another bathroom isn’t the most complicated project you can undertake, but it’s in the top 5%. Anything involving plumbing and electrical work should be handed off to a pro, and adding a half bath involves both. A contractor may charge $70 to $120 an hour for labor, but chances are they can work much faster and more accurately than a DIYer.

You should leave the water dripping when temperatures are below 20 degrees for three hours or longer or your power goes out in the winter. Leave the water dripping until temperatures are consistently above 20 degrees and you’ve checked for frozen pipes. With water movement in your pipes, ice is less likely to form, and your pipes are less likely to burst. The drip relieves pressure, preventing burst and leaking pipes.

Plumbers will typically take one to two hours to install a new drain pipe, but that timeline can vary based on the area’s accessibility, the drain length, and the type of drain line. Replacing an easily accessible p-trap under a sink could take as little as a half an hour, while replacing a larger section of drain line behind the wall could take as long as three to four hours. When hiring a plumber for your specific installation, ask them to provide an estimated timeline to get a more accurate assessment.

If you notice water leaking down the side of the bowl or tank and you don’t notice any cracks in the porcelain, the odds are that it’s condensation. If you notice water around the base of the toilet, this points to a leak. Check for loose bolts. A sewage odor may also indicate a broken toilet flange.
