"Patrick Longo of Longo Plumbing was the best plumber we have ever had. We had a complex problem with the large spa tub in our master bedroom. Patrick went above and beyond to diagnose the problem, order the necessary parts, contact Kohler to discuss, and fix the three issues we had with the tub. He stuck with the job until the tub was in 100 per cent excellent condition. He was prompt, courteous and very responsive. We highly recommend Longo Plumbing for any plumbing jobs big or small."

"Let me start by saying Marco is an amazing plumber. We needed our main line replaced because it was getting backed up and out of all the plumbers that came to give us an estimate he seemed the most honest. He was very attentive and communicative. When I had questions he was always very informative. He was very reliable and clean. Will definitely be hiring him if we ever need to again."

"Wow! Gerrod at Valiant Plumbing would get 6 stars if I could give them. He was professional and did a fantastic job on updating two sinks and bringing everything up to code. He paid a lot of attention to detail, including cleaning old mineral deposits. He even saved the day when a refrigerator delivery crew needed a water line disconnected but wouldn't do it themselves, Whew! Pricing and schedule availability were very reasonable and he did not try to upsale anything. Also, just a nice, decent guy. I felt comfortable having him in the house. I'd hire him again in a heartbeat and would recommend him highly. First picture is before of kitchen faucet, rest are after pictures."

Affordable Plumbers questions, answered by experts

Showers frequently experience leaks, most commonly originating from either the faucet or a malfunctioning shower drain. Detecting a leaky faucet is straightforward—listen for the constant sound of dripping water, even after you believe you've fully closed the faucet. In the case of a shower drain issue, it is often characterized by water seeping from the base, usually caused by a deteriorated seal between the shower wall and the shower tray.

Whether an earthquake gas shut-off valve is required depends on your location and circumstances. Certain cities, states, and even insurance providers mandate them, especially in areas with high seismic activity. In California, for example, while laws vary by county, most jurisdictions require a valve to be installed in newly constructed homes or when a home is sold or renovated. The Los Angeles Municipal Code specifically requires a licensed contractor for installation. Even if not required by law, installing a seismic shut-off valve is a wise safety measure. These devices automatically cut off the flow of gas during an earthquake, which can prevent gas leaks, fires, and explosions. It is recommended to check with your local building department for specific laws regarding installation, permitting, and inspections, and to ensure the valve you install is on your city's list of approved models.

Minor fixes, like leak repairs, are manageable DIY projects; however, major replacements usually require professional services to ensure safety.

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.

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.
