"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!"

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Andy came over to look at the water heater and told me what he would do and what needed to be done, it was 18 years old and out of code. He was here on time and did a great job and I liked him too. I would recommend Family First and would hire Andy again."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

Plumbing questions, answered by experts

Baking soda and vinegar aren’t just great for making a volcano for your kid’s science project. You can also pour this dynamic duo down your shower drain to dissolve hair clogs. If that doesn’t do the trick, you can step it up with a commercial liquid drain cleaner. 

The first rule of plumbing is nothing but water, toilet paper, number one, and number two go down the drain. 

To prevent clogs, get yourself:

  • A compast pail where you can clean plates, drain grease, and toss scraps and paper towels. 

  • Drain screens for the shower, tub, and bathroom sink to stop hair, jewelry, toys, etc. from going down the drain.

  • Trash cans for everything that shouldn’t go down the drain, like dental floss, hygiene products, and cat litter.

P.S.: If you do drop your priceless ring down the drain, take a deep breath, and then follow these steps to retrieve jewelry from your drain.

If you notice water dripping from your bathroom fan, you likely have an accumulation of condensation. The fan pulls warm, wet air from your bathroom and into the attic. However, if the water accumulates as condensation over time, it can begin to drip back out of your bathroom fan. It’s important to take action quickly to prevent mold growth and water damage.

The general rule of thumb is that you should clean your pipes every 18 to 22 months, although the process for cleaning depends on the severity of the issue and what type of pipes you have.

That being said, regular maintenance on your pipes can help prevent the need for a full-on replacement and help extend the lifetime of your pipes by quite a bit.

You should flush your water heater at least once a year, with some experts recommending a schedule of every six to 12 months (e.g., once in the spring and fall). The ideal frequency depends on several factors.

If your area has hard water with high mineral concentrations, you should flush the heater more often—typically every four to six months. Additionally, a water heater that is used frequently may require more frequent flushing than one that is used less often.

Regular flushing is important because it removes sediment buildup from the bottom of the tank. This maintenance helps improve the heater's efficiency, extend its lifespan, and prevent issues like clogs, overheating, and increased energy consumption. You can either learn to perform this task yourself or arrange for a service plan with a professional plumber.
