"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!"

"I hired General Plumbing and Rooter to help me replace my home’s main water line that ruptured last weekend. I diligently started looking for qualified plumbers and started assessing the different project options. After collecting multiple bids, I elected to go with Ray Ramirez, the owner of company, who offered helpful advice and was very patient as I went through the bidding process. Immediately he and his crew started the project and replaced my line with beautiful 1” copper pipe! The City Inspector signed off the project and commented on what a nice job was done! I now have the best water pressure in my home since I bought the place 12 years ago!! Thank you Ray and crew for helping me navigate the project during this challenging time (during COVID-19 pandemic ). I highly recommend their work and professional helpful approach."

Plumbing FAQs, answered by experts

PEX pipes can freeze. While they are less likely to burst than rigid pipes like copper or galvanized steel, it is still possible. PEX is flexible and can expand as water freezes and contract as it thaws. However, this expansion can cause leaks around the pipe's connections. Furthermore, frequent freezing and thawing cycles can stress and weaken the material over time, increasing the risk of a future burst. Therefore, even though PEX is freeze-resistant, it is not freeze-proof, and standard insulation precautions are still recommended to prevent freezing.

Problems with a damaged handle or valve cartridge can result in a leaking faucet that won’t turn off completely. The faucet may also be rusty or corroded, which can prevent the faucet from turning the water off all the way. A leaky faucet can cause issues beyond the annoying dripping sound. It also wastes water and can be an indication that something else is wrong with the system, so fix a leaky bathtub faucet as soon as possible.

Pedestal sinks are bolted or screwed into the floor and the wall to prevent it from moving out of place. You may have to change or add to the bathroom flooring when installing a pedestal sink if the flooring was laid around the previous sink, not under it.

Homeowners insurance usually doesn’t cover sewer backups because it’s typically an avoidable problem with proper maintenance. The only exception would be if the backup is occurring because of local flooding and only if your city uses a combined drainage system for stormwater and sewage. If that’s the case, your policy should cover any resulting damage.

While frozen pipes will eventually thaw on their own as temperatures rise, it is not safe to let this happen unattended. As the ice blockage melts, water can become trapped, building up extreme pressure within the pipe. This pressure can cause the pipe to burst, leading to severe water damage, costly leaks, and serious damage to your plumbing system. It is best to handle frozen pipes as quickly as possible. If you do not see any visible damage, you can try to slowly warm the pipes by increasing warm air circulation or applying warm towels. However, if you spot any leaks or damage, you should call a plumber immediately. The best course of action is always to take preventative measures to stop pipes from freezing.
