"Andrew was great on time and personable. He knew what he was doing and even showed me the issues. He fixed what he was able to and advised me on what I need to do next since the next issue was not the plumbing. When I was urgently looking for someone to come fix the leak I had, everyone else was unable to make it the day of. Andrew made it in an hour from speaking with him. I would recommend his services to anyone needing a plumber."

"1 & Done Plumbing has done an excellent job in finding and fixing the water leak(which a couple of other plumbers couldn't find)from the shower stall. Anthony and Andrew(the father and son duo) are honest and dedicated workers. I do not hesitate in seeking help from them again."

"They cut out the old dry wall, removed any and all mold, then replaced the dry wall, placed a tub and shower unit, they had their plumber come in and adjust our piping and install our new shower head and tub faucet all within 6-7 hrs. The installers were very nice, respectful, polite young men-- I would 10/10 recommend this company!!"

"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

Affordable Plumbers FAQs, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

A faulty fill valve is the likely source of noise in your pipes after flushing a toilet. The valve is what’s responsible for bringing in the additional water needed when you flush a toilet. If this valve malfunctions, then it causes a sudden change in water pressure, which results in noises in the pipes.

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

Yes, pipes can freeze during the winter months. If temps dip below 20 degrees Fahrenheit for six or more hours, your insulated pipes are more at risk, while uninsulated pipes can freeze if temps fall below 32 degrees for around 12 hours. Exterior pipes are more likely to freeze than interior pipes. The best way to prevent freezing pipes is by insulating your pipes, keeping your home’s temperature above 55 degrees, opening cabinets and doors containing pipes to promote circulation, dripping faucets, and disconnecting hoses.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.
