"Scotty provided a clear and detailed explanation of all my options, promptly restored my hot water heater to working condition, and informed me that the unit was out of warranty and may soon require a complete replacement. I found him to be highly knowledgeable, honest, and transparent throughout the process. Moving forward, he will be my primary plumber, and I will rely on him for all future plumbing projects."

"Richard came out and put a new dishwasher in for us. Good guy, showed up right on time and didn't leave a mess behind. He made sure everything was working perfect and didn't leak before he left. It's hard to find someone who actually does what they say they're gonna do these days. Will definitely use him again next time something breaks down. Highly recommend Bidwell Home Services."

Plumbing FAQs, answered by experts

Running hot water through frozen pipes can help thaw them, but it's not always a guaranteed solution. To prevent pipes from freezing in the first place, it’s crucial to open the hot and cold faucets connected to the frozen pipes and allow a slow, steady stream of water to flow. Additionally, applying gentle heat using a hairdryer or heat tape can expedite the thawing process. If the pipes remain frozen, professional assistance may be necessary to prevent damage.

You can adjust your water pressure using the water pressure regulator, which is a valve that's usually located near your water main valve. Opening and closing that valve dictates how much water pressure your house receives. You can also potentially increase your water pressure by purchasing a water pressure booster and hiring a pro to install it for you. 

While flooding is always cause for alarm, certain situations are considered more urgent than others. If there is water pooling anywhere in your basement, it’s time to call a local emergency plumber ASAP. Standing water in your basement could be from a plumbing leak or from cracks in your foundation—either situation can go from minor to major very quickly. On average, the cost to hire an emergency plumber ranges from $100 and $500, depending on the scope of the repair and when you call them—calling an emergency plumber on the weekend or on a holiday will cause the rate to jump.

You can use a stud finder or wall scanner to detect plumbing behind a wall. A stud finder can help detect metal plumbing pipes. Or, you can use a wall scanner, a special tool that many pros use to detect pipes when water is running. Make sure a faucet is on nearby to get the water flowing before you fire up the wall scanner.

There are three main types of shower valves: pressure-balancing, thermostatic, and diverter. Pressure-balancing and thermostatic valves are both considered mixing valves because they regulate water flow and temperature, but they do so in different ways. A pressure-balancing valve senses changes in water pressure, such as from a flushing toilet, and adjusts the incoming hot and cold water to maintain a consistent temperature; these typically use a single knob. A thermostatic valve uses a thermostat to precisely control the water temperature and requires a separate control to adjust the water volume. A diverter valve directs the flow of water from one fixture to another, such as switching from a tub faucet to a showerhead in a tub-shower combination.
