"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

To find a leak in a small pool, place a few drops of food coloring in a random area. If the food coloring flows out, you've found your leak. However, this can be time-consuming and impractical in larger pools. The best option is to hire a pool repair specialist with ultrasonic equipment.

If nothing is coming out of your faucet, you could have frozen pipes, a clogged faucet, or your water supply could be shut off. First, check your shut-off valves. If it's a hot sunny day, you can rule out frozen pipes and look closer at your aerator for signs of mineral deposits. Removing the aerator and cleaning it out can often return water flow. If temperatures are below freezing, you may have frozen pipes. Knowing what to do when pipes freeze is essential for thawing your pipes and preventing them from bursting.

Depending on the home, wastewater either goes into a septic tank and seeps back into the backyard or is sent via sewer system to a local sewage-treatment plant. Septic systems naturally separate different components of the waste so that it can naturally and safely disperse it. They are usually reserved for homes not served by a municipal sewage department (like rural homes). A treatment plant, on the other hand, speeds up that process through screening and purification.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.
