"Our sewer main busted and Oak Plumbing’s master plumbers Matt & Mike did a great job at digging down over 7ft to replace the broken section and also upgraded my single sewer main clean out which was nearly rusted through to a dual solid ABS clean out. And also I would like to add that Nate also did a great job at identifying our problem! Thanks guys! You’re AWESOME!"

"The proprieter, Mr. Hernandez, helped me select a new tankless water heater to replace my old one. He was generally easy to communicate with and did what he said he was going to do. Although this was a replacement water heater, the plumbing had to be replaced to fit the new unit. A few hours after he installed the new water heater, I noticed a minor problem, texted Mr. Hrnandez, and he was at my house an hour later, at 9:00 pm, to fix it. I have had many craftsmen work on my house over the years. It's usually pretty frustrating and aggravating. When there was a problem after other jobs, most of them told me my house was defective, admitted that the problem was their fault but refused to fix it, claimed that I did not understand the situation, or just stopped responding to my communications. Mr., Hernandez responded instantly to my text message and was at my house an hour later (at 9:00 pm) to fix the problem. He is a skilled professional plumber and an honorable person. I hope to do some significant remodeling that will require rebuilding some of my house's plumbing, and I'll try to get Mr. Hernandez to come back for the work."

Plumbing FAQs, answered by experts

Schedule regular inspections, fix minor issues promptly, and ensure proper drainage.

No, you can’t convert a gravity-flush toilet to a pressure-assist toilet. Pressure-assist toilets include a tank-within-the-tank, and a standard gravity-flush toilet doesn’t have a capability to include the additional tank. If you want the benefits of a pressure-assist toilet, you’ll have to make the investment in a new one. 

Replacing a toilet costs between $275 and $480 in most cases, and the average cost sits around $375. This includes removing the old toilet and installing the new toilet. Your price could be significantly higher if you invest in a high-quality brand, need the replacement done on an emergency basis, or replace your toilet as a part of a larger bathroom remodel that demands additional work.

Some of the problems with in-wall toilets include the complex installation, which might need extra framing. It is also more difficult to access the toilet tank for maintenance or troubleshooting because it’s behind the flush button panel and in the wall. Over time, you’ll spend more on maintenance because you’ll need a plumber to work on hidden plumbing.

Check connections, clean fixtures, and apply finishing or protective coatings to preserve months' worth of shine and functionality.
