"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"Jose (with JRC Plumbing) did an excellent job replacing my kitchen faucet. He quickly responded to my request and was on time to the job site. He was clean and effecient (everything you hope for in a plumber inside your home)! His attention to the details (making sure the faucet was centered and no smudges) was definately appreciated. I highly recommend Jose for your next job!"

"I purchased a water heater from Do It Right Plumbers . The tech, Chris, was on time and very thorough The installation went as smooth as could be. When the work was finished, you wouldn't have known any work had been done. It was that clean. Not only would I recommend them, but I also plan to use them in the future for my plumbing needs."

"We’ve had so many plumbing projects over the years and have always used Rapid Rescue. They have replaced our water heater, completely plumbed two bathrooms & worked on the house mainline as well as the gas line and hooking up the water lines for the washer & dryer. They are honest, reliable and affordable. The work they have done has been top notch and it lasts. I highly recommend Wes and Rapid Rescue for all of your plumbing needs."

"We had a great experience with GG’s Plumbing at our cabin in Lake Arrowhead. We originally hired them to install a whole-house water shut-off system, and the job was done quickly and professionally. While they were there, the team noticed that our pipes weren’t properly insulated — something that can obviously become a real issue in the mountains during winter. What I appreciated most was their approach: they didn’t pressure us at all. They simply explained the risk, gave us the option to fix it now or later, and let us decide. That kind of honesty goes a long way. We chose to go ahead and have the insulation done, and I’m glad we did. Their team was easy to work with, the communication (mostly through text) was fast and clear, and everything was handled smoothly. Reliable, knowledgeable, and straightforward — I would absolutely recommend GG’s Plumbing."

Plumbing FAQs, answered by experts

There are many reasons why water pipes leak. The most common reasons include clogs, broken rubber seals that deteriorate over time, corrosion on copper, brass, or galvanized pipes, and damaged pipe joints.

You might also have a leak if your water pressure is too high (usually higher than 60 psi) or if your fixtures have a crack. Moreover, natural changes in the area around your underground pipes, like growing tree roots, flooding, or earthquakes, can cause leaky water pipes.

If you notice your main water shut-off valve is leaking, try tightening the valve slightly to see if it stops the leak. If the leak persists or worsens, it’s best to contact a licensed plumber to assess and repair the valve. Using too much force or attempting a DIY repair can further damage the valve.

Most gas stoves either have a shutoff valve inside the oven drawer compartment or behind the stove wall. Cooktop shutoff valves are usually inside the base cabinet, and wall ovens usually have a shutoff valve in the cabinet below or next to the unit. Construction regulations require installing a shutoff valve within six feet of the appliance. So, if you can’t find the valve on the appliance, look around the connecting gas pipes within the six-foot radius.

There are several signs that can indicate you have air in your pipes, including unusual noises coming from the pipes, like banging and whistling, and inconsistent water flow and pressure. Spitting from the faucet right when you turn the water on is another indication that you might have air in the pipes.

Yes, before you can connect to a public sewer, you must gain permission from the water company near you. You'll also need to ensure that you comply with local regulations prior to connecting to a public sewer line. Apply to your local water authority by looking at their website for an application or by giving them a call to have your home ready for a seamless sewer line connection.
