"Ned with Mast Plumbing has been great to work with. I?ve hired him for work at my house, which involved relocating the plumbing for my washing machine, extending and repairing some water and drain lines. Ned has also helped several of my friends and some of my clients I?ve referred to him with projects ranging from plumbing new gas lines, tankless water heater installs and installing new water mains. Ned is clearly very experienced, professional and patient. He explains the process clearly, and is honest about your best options. I highly recommend Ned with Mast Plumbing, and will continue to refer him to anyone I find in need of a quality plumber."

"Our service tech, Devan, arrived promptly for an after hours call. He was courteous, professional, and knowledgeable. Showed us exactly where our blockage was and remedied it for a very reasonable price. Having many horrible experiences with plumbers in the last 40 years, I feel like I've finally got a go-to plumber with All About Rooter, LLC ."

"Harts dispatch kept me updated on the status of the plumbers arrival. We called for two issues and of course the mystery noise stopped the day he came! But he was able to fix the low pressure in the sink by replacing the faucet. All other plumbing companies we had out said our only option was to replace the old galvanized pipes! I truly appreciate that Konner took the time to look at the issue, listen to us and come up with a solution that worked and not just say the most expensive option of replacing all the pipes! Highly recommend using Harts!"

"Bath Conversion owner Kevin visited me and listened patiently what I wanted. I wanted to replace the bathtub for the soaked one and add to the shower. Total cost was fair. Once he had a tub, he contacted me then they worked so hard, had almost done in one day. The second day was just finishing and took less than one hour. They cleaned everything. They were very friendly and very professional. I strongly recommend this company to others. Thank you, Kevin."

Plumbing FAQs, answered by experts

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

Yes, you should leave outside faucets dripping in freezing weather to prevent frozen and burst pipes. While a drip doesn't always prevent freezing, ice is less likely to form and there's less pressure in your pipes, meaning they’re less likely to burst. You can also winterize your outdoor faucets, eliminating the need to run a drip.

Yes, because any trapped moisture can have a negative impact on the integrity of the wall or façade of the building. Per the 2015 International Residential Code and Commentary: “Weepholes shall be provided in the outside wythe of masonry walls at a maximum spacing of 33 inches (838 mm) on center. Weepholes shall be not less than 3/16 inch (5 mm) in diameter. Weepholes shall be located immediately above the flashing.”

Most toilets have a 12-inch rough-in or hole, but some have 10- or 14-inch holes, which means that not all toilets fit all setups. Knowing how to measure the rough-in is essential, so you purchase a toilet that fits the existing drain hole. It can be costly to have the rough-in moved, and most stores don’t accept toilet returns.

No, a larger well pressure tank will not increase your home's water pressure by itself. Water pressure is determined by the pressure control switch on the well pump.

However, a larger tank does offer other benefits. It can store more water, which allows you to run water for longer periods before the pump needs to turn on. This reduces how often the pump cycles on and off, leading to less wear and tear on the pump and the entire well system. Consequently, a larger tank can help extend the life of your equipment and may prevent future pump issues that could affect water pressure.

If your goal is to increase water pressure, consider these alternatives:

  • Adjust the pressure settings on your tank to a higher PSI (pounds per square inch).

  • Replace your current pump with a model that has a higher flow rate, measured in gallons per minute (GPM).

  • Have a professional install a water pressure booster pump in your plumbing system.

  • If you experience pressure fluctuations, consider upgrading to a constant pressure system.
